If Location is ieTBitmap, then only pf1bit and pf24bit and pf32bit are accepted.


Example


// Display the same image as a TImage
ImageEnView1.IEBitmap.CopyFromTBitmap( Image1.Picture.Bitmap );
ImageEnView1.Update();

// Copy 32bit BMP to TIEBitmap with Alpha
iebmp := TIEBitmap.Create();
bmp := TBitmap.create;
... Get 32bit Bitmap, e.g. bmp.LoadFromFile('D:\BMP32.bmp');
iebmp.CopyFromTBitmap( bmp );
iebmp.SynchronizeRGBA(True, True); // Convert 32bit RGBA to 24bit Image + Alpha channel
iebmp.Write( 'D:\Alpha.png' );
bmp.Free;
iebmp.Free;
