TIEBitmap.FillRect

Declaration

procedure FillRect(x1, y1, x2, y2: integer; Value: double);

Description

Fills the rectangle with a specified color.

Pixel Format	Value
ie1g	Specify either 0 or 1
ie8g, ie8p	Specify value between 0 and 255
ie16g	Specify value between 0 and 65535
ie24RGB, ie32RGB, ie48RGB, ieCMYK, ieCIELab	Specify TColor

For ie1g images, values can be 0 or 1. For ie8g and ie8p, values can be from 0 to 255.
For ie16g images, values can be from 0 to 65535.
For ie24RGB, ie32RGB, ieCMYK and ieCIELab values are a TColor value.

Note: Rect values are inclusive so FillRect(0, 0, 5, 5, clWhite) will fill a 6x6 pixel square

Example

// Fill image rect with white
IEBitmap.FillRect( 100, 100, 200, 200, clWhite );

// Fill monochrome image rect with white
IEBitmap.FillRect( 100, 100, 200, 200, 1 );

// Remove all transparency from image (make it fully opaque)
iebmp.AlphaChannel.FillRect( 0, 0 iebmp.Width - 1, iebmp.Height - 1, 255 );
