- CreateWithBitmap (Image As Bitmap, ModeX As TileMode, ModeY As TileMode) As AS_Texture
Creates a texture with the given bitmap. This texture can be repeated or mirrored.
Image: a bitmap containing the texture image.
ModeX,ModeY: one of the TILEMODE constants for each axis.
- Merge (Tex1 As AS_Texture, Tex2 As AS_Texture, MergeMode As Mode) As AS_Texture
Merges two textures of different types (a bitmap and a radial gradient for example).
The returned texture cannot be merged with another texture.
Tex1,Tex2: the textures to merge. They must be of different types.
MergeMode: one of the MERGEMODE constants.
- Translate (OffsetX As Int, OffsetY As Int)
Translates the origin point.
Properties:
- IsInitialized As Boolean [read only]
AcceleratedSurface
Events:
- Draw (AC As AS_Canvas)
- Touch (Action As Int, X As Int, Y As Int, Event As Object)
- Update (ElapsedTime As Long)
Methods:
- BringToFront
- ElapsedTimeSinceLastDraw As Long
Gets the elapsed time (in milliseconds) since the last Draw event.
Returns always 0 if StartRegularDraw was not called.
- Initialize (EventPrefix As String, IsHardwareAccelerated As Boolean)
Initializes the accelerated surface.
IsHardwareAccelerated: This setting should be set to true to benefit from the hardware acceleration.
It is ignored by Android versions prior to Honeycomb (3.0, API 11).
- Invalidate
- Invalidate2 (arg0 As Rect)
- Invalidate3 (arg0 As Int, arg1 As Int, arg2 As Int, arg3 As Int)
- IsInitialized As Boolean
- RemoveView
- RequestFocus As Boolean
- SendToBack
- SetBackgroundImage (arg0 As Bitmap)
- SetLayout (arg0 As Int, arg1 As Int, arg2 As Int, arg3 As Int)
- StartRegularDraw (Interval As Int)
Fires automatically the Draw event at regular intervals (in milliseconds).
This function will attempt to honor the requested interval, but the actual delay
between Draw events may be different, depending on system load and capabilities.
- StartRegularUpdateAndDraw (Interval As Int)
Fires automatically an Update event and a Draw event at regular intervals (in milliseconds).
This function will attempt to honor the requested interval, but the actual delay
between events may be different, depending on system load and capabilities.
- StopRegularDraw
Stops the timer started with StartRegularDraw or StartRegularUpdateAndDraw.
Properties:
- Background As Drawable
- Bitmap As Bitmap [read only]
Returns a screenshot of the current contents of the view.
- Color As Int [write only]
- Enabled As Boolean
- Height As Int
- IsHardwareAccelerated As Boolean [read only]
Gets whether the view is hardware accelerated.
If the view is not hardware accelerated under Android 3 or +, check that you set IsHardwareAccelerated
to true in Initialize and that you added SetApplicationAttribute(android:hardwareAccelerated, "true")
to the manifest.
- Left As Int
- Tag As Object
- Top As Int
- Visible As Boolean
- Width As Int
