Declaration
procedure CopyToTBitmap(Dest: TBitmap);
Description
Copies the image to the
Dest TBitmap object. These
PixelFormat conversions are applied:
ie1g -> pf1bit
ie8p -> pf8bit
ie8g -> pf8bit (create gray scale palette)
ie16g -> pf8bit (copy only high 8 bit)
ie24RGB -> pf24bit
ie32RGB -> pf32bit
Note: To output as a 32bit (RGBA) bitmap image (with an
alpha channel), call SynchronizeRGBA( False, True ); before CopyToTBitmap()
Examples
// Copy the displayed image to a TBitmap
ImageEnView1.IEBitmap.CopyToTBitmap( MyBmp );
// Copy the displayed image to a TImage
ImageEnView1.IEBitmap.CopyToTBitmap( Image1.Picture.Bitmap );
// Load a RAW image into a TImage
myBmp := TIEBitmap.create;
myBmp.Read( 'C:\camera.dng' );
myBmp.CopyToTBitmap( Image1.Picture.Bitmap );
myBmp.Free;
// Output content of TImageEnView as a 32bit Bitmap with alpha channel
var
bmp: TBitmap;
begin
bmp := TBitmap.Create();
ImageEnView1.IEBitmap.SynchronizeRGBA( False, True ); // Convert 24bit Image + Alpha channel to 32bit RGBA
ImageEnView1.IEBitmap.CopyToTBitmap( bmp );
... bmp is now 32bit
bmp.Free();
end;
// Copy TIEBitmap with Alpha to 32bit BMP
iebmp := TIEBitmap.Create();
bmp := TBitmap.create;
iebmp.Read( 'D:\OriginalAlpha.png' );
iebmp.SynchronizeRGBA( False, True ); // Convert 24bit Image + Alpha channel to 32bit RGBA
iebmp.CopyToTBitmap( bmp );
... Do something with bitmap, e.g. bmp.SaveToFile( 'D:\BMP32.bmp' );
bmp.Free;
iebmp.Free;
