ImageCropper view (MFImageCropper.jar)
Like CropImageView​

Joystick and Slider view (MFJoy.jar)

Lua script interpreter (MFLibLua.jar)
Lua 5.2 interpreter to script your app. It contains the complete MFLib base library because many of these functions are implemented as Lua functions.
You can implement your own functions in the interpreter.​


Example apps for base, image, parser and Lua functions included.


Additionally the package contains the MFLib native Library selector (Windows program).
With this selector you can select which native library platforms (arm, arm v7, arm 64, x86, ...) should be included in the libs, individually for each project.


Drawback: this new version is donationware and not free.

For a donation of at least 10 Euro i will send you the download info for the base library setup (all functions/objects and the examples, but without the Lua library).
On library updates i inform you with download info for the new version.

For a donation of 15 Euro i will send you the download info for the extended library setup (all functions/objects and the examples, including the Lua library).

For a donation of 20 Euro i will send you the download info for the extended library setup and for the max library setup when available (end of year/beginning next year).
The max library is same as the extended library and additionally with motion detection class.

The old version 1.07 will be free forever but it's not longer maintained.

    • ColorNearComplementary (argb As Int, angle As Float) As Int
      Takes the given color and creates the complementary color with a twist.
      The high contrast of complementary colors creates a vibrant look especially when used at full saturation. This color scheme must be managed well so it is not jarring.
      Complementary colors are tricky to use in large doses, but work well when you want something to stand out.
      Complementary colors are really bad for text.
      The returning color is the color right (+angle) or left (-angle) from the complementary color.
      "angle" can be a value between -45 and +45.
    • ColorSplitComplementary (argb As Int, angle As Float) As Int[]
      Takes the given color and creates a list of three split complementary colors.
      The split-complementary color scheme is a variation of the complementary color scheme. In addition to the base color, it uses the two colors adjacent to its complement.
      This color scheme has the same strong visual contrast as the complementary color scheme, but has less tension.
      The split-complimentary color scheme is often a good choice for beginners, because it is difficult to mess up.
      Element 0 of the returned list is the given color, element 1 the color left (-angle) from the complementary color and element 2 the color right (+angle) from the complementary color.
      "angle" can be a value between >0 and 45.

      Triadic color harmonies tend to be quite vibrant, even if you use pale or unsaturated versions of your hues.
      To use a triadic harmony successfully, the colors should be carefully balanced - let one color dominate and use the two others for accent.
      Element 0 of the returned list is the given color, element 1 the color +120 degree from the given color and element 2 the color +240 degree.

    Methods:
    • AbsIndex (index As Int) As Int
      Converts the acceptable index 'index' into an absolute index (that is, one that does not depend on the stack top).
    • AddSearchPath (path As String)
      Add a path to the Lua search paths environment.
      If 'path' is '/data/data/progdir/files' then the following two entries will be added:
      '/data/data/progdir/files/?.lua'
      '/data/data/progdir/files/?/init.lua'
    • Arith (op As Int)
      Performs an arithmetic operation over the two values (or one, in the case of negation) at the top of the stack,
      with the value at the top being the second operand, pops these values, and pushes the result of the operation.
      The function follows the semantics of the corresponding Lua operator (that is, it may call metamethods).

      The value of op must be one of the following constants:

      LUA_OPADD: performs addition ( + )
      LUA_OPSUB: performs subtraction ( - )
      LUA_OPMUL: performs multiplication ( * )
      LUA_OPDIV: performs division ( / )
      LUA_OPMOD: performs modulo ( % )
      LUA_OPPOW: performs exponentiation ( ^ )
      LUA_OPUNM: performs mathematical negation ( unary - )
    • Call (argCount As Int, returnCount As Int) As Boolean
      Calls a function.
      To call a function you must use the following protocol: first, the function to be called is pushed onto the stack;
      then, the arguments to the function are pushed in direct order; that is, the first argument is pushed first.
      Finally you call Call; 'argCount' is the number of arguments that you pushed onto the stack.
      All arguments and the function value are popped from the stack when the function is called.
      The function results are pushed onto the stack when the function returns. The number of results is adjusted to 'returnCount',
      unless 'returnCount' is LUA_MULTRET. In this case, all results from the function are pushed.
      Lua takes care that the returned values fit into the stack space. The function results are pushed onto the stack
      in direct order (the first result is pushed first), so that after the call the last result is on the top of the stack.
    • Call2 (args() As Object, returnCount As Int) As Boolean
      Calls a function.
      To call a function you must first push the function to be called onto the stack.
      Finally you call Call2; 'args' is an array with arguments (allowed types: 'Boolean', 'Int', 'Double' or 'String').
      The function value are popped from the stack when the function is called.
      The function results are pushed onto the stack when the function returns. The number of results is adjusted to 'returnCount',
      unless 'returnCount' is LUA_MULTRET. In this case, all results from the function are pushed.
      Lua takes care that the returned values fit into the stack space. The function results are pushed onto the stack
      in direct order (the first result is pushed first), so that after the call the last result is on the top of the stack.
    • CallFunc (func As String, args() As Object, returnCount As Int) As Boolean
      Calls the global function with the name 'func'.
      If 'func' is a script defined function then the script must first called with 'Call()' or 'Call2()', otherwise the function is not defined.
      'args' is an array with arguments (allowed types: 'Boolean', 'Int', 'Double' or 'String').
      The function results are pushed onto the stack when the function returns. The number of results is adjusted to 'returnCount',
      unless 'returnCount' is LUA_MULTRET. In this case, all results from the function are pushed.
      Lua takes care that the returned values fit into the stack space. The function results are pushed onto the stack
      in direct order (the first result is pushed first), so that after the call the last result is on the top of the stack.
    • CheckArg (index As Int, cond As Boolean, msg As String)
      Checks if a condition is true for the specified function argument. If not, the method throws a Lua runtime exception with the specified error message.
    • CheckBoolean2 (index As Int, def As Boolean) As Boolean
      Returns the function argument 'index' as boolean.
      The function uses 'def' as a default value when there is no argument 'index'.
    • CheckByteArray (index As Int) As ByteBuffer
      Checks if the value of the specified function argument is a string or a number. If so, the argument value is returned as a byte array.
      Otherwise, the method throws a Lua runtime exception with a descriptive error message.
    • CheckByteArray2 (index As Int, def As ByteBuffer) As ByteBuffer
      Checks if the value of the specified function argument is a string or a number. If so, the argument value is returned as a byte array.
      Otherwise, the method throws a Lua runtime exception with a descriptive error message.
      The function uses 'def' as a default value when there is no argument 'index'.
    • CheckInteger (index As Int) As Int
      Checks whether the function argument 'index' is a number and returns this number cast to a integer.
    • CheckInteger2 (index As Int, def As Int) As Int
      Checks whether the function argument 'index' is a number and returns this number cast to a integer.
      The function uses 'def' as a default value when there is no argument 'index' or when this argument is nil.
    • CheckNumber (index As Int) As Double
      Checks whether the function argument 'index' is a number and returns this number.
    • CheckNumber2 (index As Int, def As Double) As Double
      Checks whether the function argument 'index' is a number and returns this number.
      The function uses 'def' as a default value when there is no argument 'index' or when this argument is nil.
    • CheckOption (index As Int, options() As String) As Int
      Checks whether the function argument arg is a string and searches for this string in the array lst (which must be NULL-terminated).
      Returns the index in the array where the string was found. Raises an error if the argument is not a string or if the string cannot be found.

      This is a useful function for mapping strings to C enums. (The usual convention in Lua libraries is to use strings instead of numbers to select options.)
    • CheckOption2 (index As Int, options() As String, def As String) As Int
      Checks whether the function argument arg is a string and searches for this string in the array lst (which must be NULL-terminated).
      Returns the index in the array where the string was found. Raises an error if the argument is not a string or if the string cannot be found.
      The function uses 'def' as a default value when there is no argument 'index' or when this argument is nil.

      This is a useful function for mapping strings to C enums. (The usual convention in Lua libraries is to use strings instead of numbers to select options.)
    • CheckString (index As Int) As String
      Checks whether the function argument 'index' is a string and returns this string.
    • CheckString2 (index As Int, def As String) As String
      Checks whether the function argument 'index' is a string and returns this string.
      The function uses 'def' as a default value when there is no argument 'index' or when this argument is nil.
    • CheckType (index As Int, t As Int)
      Checks whether the function argument 'index' has type 't'. See type for the encoding of types for 't'.
    • Close
      Close the Lua interpreter instance.
    • Compare (index1 As Int, index2 As Int, op As Int) As Boolean
      Compares two Lua values. Returns true if the value at index 'index1' satisfies 'op' when compared with the value at index 'index2',
      following the semantics of the corresponding Lua operator (that is, it may call metamethods). Otherwise returns false.
      Also returns false if any of the indices is non valid.

      The value of op must be one of the following constants:

      LUA_OPEQ: compares for equality ( == )
      LUA_OPLT: compares for less than ( < )
      LUA_OPLE: compares for less or equal ( <= )
    • Concat (n As Int)
      Concatenates the 'n' values at the top of the stack, pops them, and leaves the result at the top. If 'n' is 1,
      the result is the single value on the stack (that is, the function does nothing); if 'n' is 0, the result is the empty string.
      Concatenation is performed following the usual semantics of Lua.
    • Copy (fromIndex As Int, toIndex As Int)
      Moves the element at index 'fromIndex' into the valid index 'toIndex' without shifting any element (therefore replacing the value at that position).
    • Copyright As String
      Returns the MFLib copyright string.
    • Dump (index As Int, indent As String) As String
      Dumps the element at index 'index' to string. if 'index' is 0 then the complete stack is dumped.
      'indent' contains the characters for indenting the recursion levels.
    • Equal (index1 As Int, index2 As Int) As Boolean
      Returns true if the two values in indices 'index1' and 'index2' are primitively equal (that is, without calling metamethods). Otherwise returns false.
      Also returns false if any of the indices are non valid.
    • Gc (what As Int, data As Int) As Int
      Controls the garbage collector.

      This function performs several tasks, according to the value of the parameter what:

      LUA_GCSTOP: stops the garbage collector.
      LUA_GCRESTART: restarts the garbage collector.
      LUA_GCCOLLECT: performs a full garbage-collection cycle.
      LUA_GCCOUNT: returns the current amount of memory (in Kbytes) in use by Lua.
      LUA_GCCOUNTB: returns the remainder of dividing the current amount of bytes of memory in use by Lua by 1024.
      LUA_GCSTEP: performs an incremental step of garbage collection. The step "size" is controlled by data (larger values mean more steps) in a non-specified way. If you want to control the step size you must experimentally tune the value of data. The function returns 1 if the step finished a garbage-collection cycle.
      LUA_GCSETPAUSE: sets data as the new value for the pause of the collector. The function returns the previous value of the pause.
      LUA_GCSETSTEPMUL: sets data as the new value for the step multiplier of the collector. The function returns the previous value of the step multiplier.
      LUA_GCISRUNNING: returns a boolean that tells whether the collector is running (i.e., not stopped).
      LUA_GCGEN: changes the collector to generational mode.
      LUA_GCINC: changes the collector to incremental mode. This is the default mode.
    • GetField (index As Int, key As String)
      Pushes onto the stack the value t['key'], where t is the value at the given index. As in Lua, this function may trigger a metamethod for the "index" event.
    • GetGlobal (name As String)
      Pushes onto the stack the value of the global 'name'.
    • GetMetafield (index As Int, key As String) As Boolean
      Pushes onto the stack the field 'key' from the metatable of the object at index 'index'. If the object does not have a metatable, or if the metatable does not have this field, returns false and pushes nothing.
    • GetMetatable (index As Int) As Boolean
      Pushes on the stack the metatable of the value at the specified index. If the value does not have a metatable, the method returns false and nothing is pushed.
    • GetTable (index As Int)
      Pushes onto the stack the value t[k], where t is the value at the given index and k is the value at the top of the stack.

      This function pops the key from the stack (putting the resulting value in its place). As in Lua, this function may trigger
      a metamethod for the 'index' event.
    • GetTop As Int
      Returns the index of the top element in the stack. Because indices start at 1, this result is equal
      to the number of elements in the stack (and so 0 means an empty stack).
    • HasFunction (func As String) As Boolean
      Check if a global function with the name 'func' exists.
      If 'func' is a script defined function then the script must first called with 'Call()' or 'Call2()', otherwise the function is not defined.
    • Initialize
      Initialize the Lua interpreter instance.
    • Insert (index As Int)
      Moves the top element into the given valid index, shifting up the elements above this index to open space.
      This function cannot be called with a pseudo-index, because a pseudo-index is not an actual stack position.
    • IsBoolean (index As Int) As Boolean
      Returns true if the value at the given index is a boolean, and false otherwise.
    • IsCFunction (index As Int) As Boolean
      Returns true if the value at the given index is a C function, and false otherwise.
    • IsFunction (index As Int) As Boolean
      Returns true if the value at the given index is a function (either C or Lua), and false otherwise.
    • IsInitialized As Boolean
    • IsNil (index As Int) As Boolean
      Returns true if the value at the given index is nil, and false otherwise.
    • IsNone (index As Int) As Boolean
      Returns true if the given index is not valid, and false otherwise.
    • IsNoneOrNil (index As Int) As Boolean
      Returns true if the given index is not valid or if the value at this index is nil, and false otherwise.
    • IsNumber (index As Int) As Boolean
      Returns true if the value at the given index is a number or a string convertible to a number, and false otherwise.
    • IsString (index As Int) As Boolean
      Returns true if the value at the given index is a string or a number (which is always convertible to a string), and false otherwise.
    • IsTable (index As Int) As Boolean
      Returns true if the value at the given index is a table, and false otherwise.
    • IsThread (index As Int) As Boolean
      Returns true if the value at the given index is a thread, and false otherwise.
    • Len (index As Int)
      Returns the "length" of the value at the given index; it is equivalent to the '#' operator in Lua. The result is pushed on the stack.
    • Length (index As Int) As Int
      Returns the raw "length" of the value at the given index: for strings, this is the string length; for tables, this is the result
      of the length operator ('#') with no metamethods; for userdata, this is the size of the block of memory allocated for the userdata;
      for other values, it is 0.
    • LessThan (index1 As Int, index2 As Int) As Boolean
      Compares two Lua values. Returns true if the value at index 'index1' is less than the value at index 'index2',
      following the semantics of the Lua operator (that is, it may call metamethods). Otherwise returns false.
      Also returns false if any of the indices is non valid.
    • LoadFile (dirName As String, fileName As String, chunkName As String) As Boolean
      Loads a Lua script from file. If there are no errors, load pushes the compiled chunk as a Lua function on top of the stack. Otherwise, it pushes an error message.
      The chunkname argument gives a name to the chunk, which is used for error messages and in debug information.
    • LoadString (script As String, chunkName As String) As Boolean
      Loads a Lua script from string. If there are no errors, load pushes the compiled chunk as a Lua function on top of the stack. Otherwise, it pushes an error message.
      The chunkname argument gives a name to the chunk, which is used for error messages and in debug information.
    • NewTable
      Creates a new empty table and pushes it onto the stack.
    • NewTable2 (arrayCount As Int, recordCount As Int)
      Creates a new empty table and pushes it onto the stack. Parameter 'arrayCount' is a hint for how many elements the table will have as a sequence;
      parameter 'recordCount' is a hint for how many other elements the table will have. Lua may use these hints to preallocate memory for the new table.
      This pre-allocation is useful for performance when you know in advance how many elements the table will have.
    • Next (index As Int) As Boolean
      Pops a key from the stack, and pushes a key-value pair from the table at the given index (the "next" pair after the given key).
      If there are no more elements in the table, then Next returns false (and pushes nothing).

      While traversing a table, do not call ToString directly on a key, unless you know that the key is actually a string.
      Recall that ToString may change the value at the given index; this confuses the next call to Next.
    • Pop (count As Int)
      Pops 'count' elements from the stack.
    • PushBoolean (value As Boolean)
      Pushes a boolean value onto the stack.
    • PushByteArray (value As ByteBuffer)
      Pushes a byte array value as a string value on the stack.
    • PushInteger (value As Int)
      Pushes a integer value onto the stack.
    • PushNil
      Pushes a nil value onto the stack.
    • PushNumber (value As Double)
      Pushes a number value onto the stack.
    • PushString (value As String)
      Pushes a string value onto the stack.
    • PushValue (index As Int)
      Pushes a copy of the element at the given index onto the stack.
    • RawEqual (index1 As Int, index2 As Int) As Boolean
      Returns true if the two values in indices 'index1' and 'index2' are primitively equal (that is, without calling metamethods). Otherwise returns false.
      Also returns false if any of the indices are non valid.
    • RawGet (index As Int)
      Similar to GetTable, but does a raw access (i.e., without metamethods).
    • RawGet2 (index As Int, key As Int)
      Pushes onto the stack the value t['key'], where t is the table at the given index. The access is raw; that is, it does not invoke metamethods.
    • RawLen (index As Int) As Int
      Returns the raw "length" of the value at the given index: for strings, this is the string length; for tables, this is the result
      of the length operator ('#') with no metamethods; for userdata, this is the size of the block of memory allocated for the userdata;
      for other values, it is 0.
    • RawSet (index As Int)
      Similar to SetTable, but does a raw assignment (i.e., without metamethods).
    • RawSet2 (index As Int, key As Int)
      Does the equivalent of t['key'] = v, where t is the table at the given index and v is the value at the top of the stack.
      This function pops the value from the stack. The assignment is raw; that is, it does not invoke metamethods.
    • Ref (index As Int) As Int
      Creates and returns a reference, in the table at index 'index', for the object at the top of the stack (and pops the object).

      A reference is a unique integer key. As long as you do not manually add integer keys into table t, Ref ensures the uniqueness
      of the key it returns. You can retrieve an object referred by reference r by calling RawGet2(t, r).
      Function Unref frees a reference and its associated object.

      If the object at the top of the stack is nil, Ref returns the constant LUA_REFNIL. The constant LUA_NOREF is guaranteed to be
      different from any reference returned by Ref.
    • Register (funcName As String, eventName As String)
      Creates a new global function 'funcName' and assigns the event 'eventName' to it.
    • Register2 (moduleName As String, funcName As String, eventName As String)
      Creates a new module (table) function 'funcName' and assigns the event 'eventName' to it.
      The (global) module 'moduleName' will be created if not exists.
    • RegisterPrint (eventName As String)
      Defines a event for the output of the Lua function print().
    • Remove (n As Int)
    • Replace (index As Int)
      Moves the top element into the given valid index without shifting any element (therefore replacing the value at the given index),
      and then pops the top element.
    • Resume (index As Int, argCount As Int) As Int
      Starts and resumes a coroutine.
      To start a coroutine, you push onto the thread stack the main function plus any arguments; then you call Resume, with 'argCount' being the number of arguments.
      This call returns when the coroutine suspends or finishes its execution. When it returns, the stack contains all values passed to Yield,
      or all values returned by the body function. Resume returns LUA_YIELD if the coroutine yields, LUA_OK if the coroutine finishes its execution without errors,
      or an error code in case of errors.

      In case of errors, the stack is not unwound, so you can use the debug API over it. The error message is on the top of the stack.

      To resume a coroutine, you remove any results from the last Yield, put on its stack only the values to be passed as results from yield, and then call Resume.

      The parameter from represents the coroutine that is resuming. If there is no such coroutine, this parameter can be nil.
    • SetField (index As Int, key As String)
      Does the equivalent to t[k] = v, where t is the value at the given index and v is the value at the top of the stack.

      This function pops the value from the stack. As in Lua, this function may trigger a metamethod for the "newindex" event.
    • SetGlobal (name As String)
      Pops a value from the stack and sets it as the new value of global 'name'.
    • SetMetatable (index As Int)
      Pops a table from the stack and sets it as the new metatable for the value at the given index.
    • SetTable (index As Int)
      Does the equivalent to t[k] = v, where t is the value at the given index, v is the value at the top of the stack, and k is the value just below the top.

      This function pops both the key and the value from the stack. As in Lua, this function may trigger a metamethod for the "newindex" event.
    • SetTop (index As Int)
      Accepts any index, or 0, and sets the stack top to this index. If the new top is larger than the old one,
      then the new elements are filled with nil. If index is 0, then all stack elements are removed.
    • Status (index As Int) As Int
      Returns the status of the thread.
      The status can be 0 (LUA_OK) for a normal thread, an error code if the thread finished the execution of a Resume with an error, or LUA_YIELD if the thread is suspended.

      You can only call functions in threads with status LUA_OK. You can resume threads with status LUA_OK (to start a new coroutine) or LUA_YIELD (to resume a coroutine).
    • TableMove (index As Int, fromIndex As Int, toIndex As Int, count As Int)
      Moves the specified number of sequential elements in a table used as an array from one index to another.
    • TableSize (index As Int) As Int
      Counts the number of entries in a table.
    • ToBoolean (index As Int) As Boolean
      Converts the Lua value at the given index to a boolean value (false or true). Like all tests in Lua, ToBoolean returns true
      for any Lua value different from false and nil; otherwise it returns false.
      (If you want to accept only actual boolean values, use IsBoolean to test the value's type.)
    • ToByteArray (index As Int) As ByteBuffer
      Returns the byte array representation of the value at the specified stack index. The value must be a string or a number.
      If the value is a number, it is in place converted to a string. Otherwise, the method returns nil.
    • ToInteger (index As Int) As Int
      Converts the Lua value at the given index to the signed integral type integer. The Lua value must be a number or a string
      convertible to a number; otherwise, tointeger returns 0.
    • ToNumber (index As Int) As Double
      Converts the Lua value at the given index to the type number. The Lua value must be a number or a string convertible to a number;
      otherwise, tonumber returns 0.
    • ToString (index As Int) As String
      Converts the Lua value at the given index to a string. The Lua value must be a string or a number; otherwise, the function returns nil.
      If the value is a number, then ToString also changes the actual value in the stack to a string.
      (This change confuses Next when ToString is applied to keys during a table traversal.)
    • Type (n As Int) As Int
    • TypeName (index As Int) As String
      Returns the name of the type encoded by the value 'tp', which must be one the values returned by Type.
    • Unref (index As Int, reference As Int)
      Releases reference 'reference' from the table at index 'index' (see Ref). The entry is removed from the table, so that the referred object can be collected.
      The reference 'reference' is also freed to be used again.

      If 'ref' is LUA_NOREF or LUA_REFNIL, Unref does nothing.
    • Version As String
      Returns the MFLib version.
    • Yield (n As Int) As Int

Hi. It seems a very big work. For now I need to capture and access the camera images, as I wrote in my initial messages. Also some filtering could be interesting, but the most of the functions you implemented is not of my interest, for now. For the moment I want to do some experiments mainly on Samsung tablets. In the future, perhaps, I can try to distribute apps based on your lib, but first I must to do some research.
What should I do to get the appropriate version of your lib? Thanks and my compliments.

Dankeschön.
Bitte!

Auch zu Dir ist die Mail mit dem Downloadlink unterwegs.
Danke.
Am meisten interessiert mich die LUA-Lib; ist eigentlich der Hauptgrund meiner Spende :)
Download mache ich später...

Keine Ahnung bez. der 404 Fehlerseite, ich vermute den Fehler bei Paypal.
Ich vermute den in deinen Einstellungen bei Paypal.

Hi. I have downloaded the library, from your link. I already answered to the mail with which you sent the link, that the Installation doesn't work. It fails saying that folder "Additional libraries" doesn't exist, but even creating it, no result is reached. In the cited mail, I have sent more info. What I suspect is that the installation uses folders with hard coded names, that differ from the names that I have. (The message says B4A/Additional libraries, but "B4A" in my computer is "Basic4Android", and, actually, it is the default name, not my choice). Please check. Thanks.

Hi Giovanny
I answered today to your mail. Please check, if the path for "Additional libraries" is set in your B4A configuration.
