public procedure TCanvas.BrushCopy( |
ADestRect: TRect; |
ABitmap: TBitmap; |
ASourceRect: TRect; |
ATransparentColor: TColor |
); virtual; |
ADestRect |
|
Rectangle on the canvas where the content from ABitmap is stored. |
ABitmap |
|
TBitmap with the pixel content copied in the method. |
ASourceRect |
|
Rectangle with the bounds for the copied region in ABitmap. |
ATransparentColor |
|
Specifies the pixel color in ABitmap which becomes transparent when copied to the destination rectangle on the Canvas. |
The end result is that pixels copied from ABitmap using the color in ATransparentColor are replaced with the brush color for the canvas. This makes the copied area in ASourceRect partially transparent when applied to ADestRect.
Pixels colors from ASourceRect are applied to a temporary image, and the StretchDraw method is called to draw the copied rectangle onto the canvas.
Set the Color property in Brush before calling the method.
|
The Brush used to paint on the Canvas. |
|
|
Expands or contracts the specific graphic content to fit the specified destination rectangle on the canvas. |
|
|
The Color of the current Brush. |
|
|
TColorToFPColor - converts a color of type TColor to one specified as a FPColor. |
|
