DrawBitmapCreator (Source As BitmapCreator, SrcRect As B4XRect, TargetX As Int, TargetY As Int, SkipBlending As Boolean) As String
Draws the image stored in the Source BitmapCreator to this BitmapCreator.
Source - Source BitmapCreator
SrcRect - Defines the region in the Source BC that will be copied.
TargetX / TargetY - Top left point in the destination BC.
SkipBlending - Whether non-opaque pixels in the source bitmap should blend with the background.
DrawBitmapCreatorsAsync (Target As Object, EventName As String, DrawTasks As List) As String
Asynchronously draws all the draw tasks. Note that no other drawings should be made until the BitmapReady event is raised.
The 'bmp' parameter will not be initialized in B4J.
Target must be a class instance.
Example: bc1.DrawBitmapCreatorsAsync(Me, "BC", Tasks)
Wait For BC_BitmapReady (bmp As B4XBitmap)

DrawBitmapCreatorTransformed (Task As DrawTask) As String
Draws a scaled and / or rotated BitmapCreator.
Task.TargetX / TargetY define the target center. This is different than the behavior in other methods.
Task.SkipBlending = True will treat all pixels with alpha > 0 as solid colors and other pixels as transparent.
DrawCircle (X As Float, Y As Float, Radius As Float, Color As Int, Filled As Boolean, StrokeWidth As Int) As BCBrush
Draws a a circle. Returns the color brush.
DrawCircle2 (X As Float, Y As Float, Radius As Float, Brush As BCBrush, Filled As Boolean, StrokeWidth As Int) As BCBrush
Draws a circle.
DrawCompressedBitmap (Source As CompressedBC, SrcRect As B4XRect, TargetX As Int, TargetY As Int) As String
Draws a CompressedBC object created with BitmapCreator.ExtractCompressBC.
DrawLine (X0 As Float, Y0 As Float, X1 As Float, Y1 As Float, Color As Int, StrokeWidth As Int) As BCBrush
Draws a line. Returns the color brush.
DrawLine2 (X0 As Float, Y0 As Float, X1 As Float, Y1 As Float, Brush As BCBrush, StrokeWidth As Int) As BCBrush

DrawPath (Path As BCPath, Color As Int, Filled As Boolean, StrokeWidth As Int) As BCBrush
Draws a BCPath. Don't confuse with B4XPath or Path.
Returns the created color brush.
DrawPath2 (Path As BCPath, Brush As BCBrush, Filled As Boolean, StrokeWidth As Int) As BCBrush
Draws a BCPath. Don't confuse with B4XPath or Path.
Non-full paths: Connection segments are drawn between each two lines. You can disable it by setting BCPath.DrawConnectionSegments to False.
This will make the drawing twice as fast (in most cases it will be fast enough anyway).
DrawRect (Rect As B4XRect, Color As Int, Filled As Boolean, StrokeWidth As Int) As BCBrush
Draws a rectangle. Returns the color brush.
DrawRect2 (Rect As B4XRect, Brush As BCBrush, Filled As Boolean, StrokeWidth As Int) As BCBrush

FillRadialGradient (GradColors() As Int, Rect As B4XRect) As String
Fills the rectangle with a radial gradient. Skips blending.
FillRect (Color As Int, Rect As B4XRect) As String
DEPRECATED: use DrawRect instead.
FlipCompressedBitmap (Source As CompressedBC, Horizontal As Boolean, Vertical As Boolean) As CompressedBC
GetARGB (x As Int, y As Int, Result As ARGBColor) As ARGBColor
Gets the color of the given point as an ARGB color.
The Result parameter stores the output.
getBitmap As B4XBitmapWrapper
Converts the bytes buffer to a bitmap.
getBuffer As Byte()
Gets the internal buffer.
GetColor (x As Int, y As Int) As Int
Gets the color of the given point as an int value.
GetPremultipliedColor (x As Int, y As Int, Result As PremultipliedColor) As PremultipliedColor
Gets the color of the given point as a premultiplied color. No conversion is required for this format.
The Result parameter stores the output.
Initialize (Width As Int, Height As Int) As String
Initializes the object and sets the bitmap dimensions.
Note that XUI library must be referenced as well.
IsInitialized As Boolean
Tests whether the object has been initialized.
IsTransparent (x As Int, y As Int) As Boolean
Tests whether a given point is completely transparent.
MAX_SAME_COLOR_SIZE As Int
mHeight As Int
mWidth As Int
ReplaceSemiTransparentPixels (NewColor As Int, Rect As B4XRect) As String
Replaces all semi-transparent pixels in the Rect with NewColor.
This can be useful to remove antialiasing effects.
SAME_COLOR_LENGTH_FOR_CACHE As Int
SetARGB (x As Int, y As Int, ARGB As ARGBColor) As String
Sets the color of the specified point.
SetBitmapToImageView (Bitmap As B4XBitmapWrapper, ImageView As B4XViewWrapper) As String
Similar to B4XView.SetBitmap. The difference is in B4A where the Gravity is set to FILL instead of CENTER.
This is useful when you want to use a scaled down bitmap.
In most cases you should use this method instead of B4XView.SetBitmap.
SetColor (x As Int, y As Int, Clr As Int) As String
Sets the color of the given pixel.
SetHSV (x As Int, y As Int, alpha As Int, h As Int, s As Float, v As Float) As String
Sets the color of the specified point.
SetPremultipliedColor (x As Int, y As Int, Premultiplied As PremultipliedColor) As String
Sets the color of the specified point.
