TIEBrushToolInteraction.AddToPainting

Declaration

function AddToPainting(BmpX, BmpY: Integer): TRect;

Description

Add extra destination points to a programmatic painting operation (i.e. to mimic a user painting operation with your own code).
Result is the area that was painted (in screen coordinates).

Normally, painting operations are performed by the user via miBrushTool, but it can be performed with code using:
1. Set the size and color of the brush
2. Start painting using StartPainting
3. Add extra points to the painting operation using AddToPainting (Optional)
4. Enact the painting changes using EndPainting

Demo

Example

// Paint a red line
ImageEnView1.BrushTool.BrushColor := clRed;
ImageEnView1.BrushTool.BrushSize  := 50;
ImageEnView1.BrushTool.StartPainting( 50, 250 );              // Start at 50,250
ImageEnView1.BrushTool.AddToPainting( 200, 250 );             // Paint to 200,250
ImageEnView1.BrushTool.AddToPainting( 200, 450 );             // Paint to 200,450
ImageEnView1.BrushTool.EndPainting();                         // Enact the changes
