TImageEnProc.SetFromRGBChannels

Declaration

procedure SetFromRGBChannels(BitmapR, BitmapG, BitmapB: TIEBitmap);

Description

Creates an image from R, G and B channel bitmaps, e.g. as created by GetRGBChannel (all existing content will be cleared).
BitmapR, BitmapG and BitmapB must be the same size and ie24RGB. They should be gray-scale.

Demos

Example

ImageEnView1.Proc.GetRGBChannel( ImageEnViewRed.IEBitmap, ImageEnViewGreen.IEBitmap, ImageEnViewBlue.IEBitmap );
ImageEnViewRed.Update();
ImageEnViewGreen.Update();
ImageEnViewBlue.Update();

... Modify the content of ImageEnViewRed, ImageEnViewGreen or ImageEnViewBlue

ImageEnView1.Proc.SetFromRGBChannels( ImageEnViewRed.IEBitmap, ImageEnViewGreen.IEBitmap, ImageEnViewBlue.IEBitmap );

Other Examples

// Load test image
ImageEnView1.IO.LoadFromFile( 'D:\TestImage.jpg' );

  


// Apply blurring to the blue color channel
bmpR := TIEBitmap.Create();
bmpG := TIEBitmap.Create();
bmpB := TIEBitmap.Create();

DestIEViewer.Proc.GetRGBChannel( bmpR, bmpG, bmpB );
bmpB.Proc.Blur( 10 );
DestIEViewer.Proc.SetFromRGBChannels( bmpR, bmpG, bmpB );

bmpR.Free;
bmpG.Free;
bmpB.Free;

  


// Flip the red channel vertically and the blue channel horizontally of an image
bmpR := TIEBitmap.Create();
bmpG := TIEBitmap.Create();
bmpB := TIEBitmap.Create();

ImageEnView1.Proc.GetRGBChannelAll( bmpR, bmpG, bmpB );
bmpR.Flip( fdVertical );
bmpB.Flip( fdHorizontal );
ImageEnView1.Proc.SetFromRGBChannels( bmpR, bmpG, bmpB );

bmpR.Free;
bmpG.Free;
bmpB.Free;
