[lazarus] help for Scanline exemple

[wile64]

Hi,

I use the example Scanline to change an image with the alpha channel as
well.

  alphaTransparent  = 0;
  alphaOpaque       = 255;


  IntfImage.CopyPixels(ScanLineImage);
  MyBitmap.LoadFromIntfImage(IntfImage);
  Canvas.Draw(10,10,MyBitmap);

The problem is that I have no transparency with this method.

How to give transparency to MyBitmap?


Thanks for help,
