with Init_BPP32_B8G8R8A8_BIO_TTB and CopyPixels in example don't work,

  IntfImage.CopyPixels(ScanLineImage);
  MyBitmap.LoadFromIntfImage(IntfImage);


Thats why I asked what the description of IntfImage was and not 
ScanLineImage.


When Copying pixels the description is not copied, but the pixels are 
matched to the description of IntfImage

That is what I suggested in my first reply.

(or change the description of IntfImage)

  Hi,
 
  I use the example Scanline to change an image with the alpha channel as

alphaOpaque   = 255;
 
 
IntfImage.CopyPixels(ScanLineImage);

 what is the Description of IntfImage ?
 Does it have an Aplha channel ?


see the Scanline example ;-)

  ScanLineImage:=TLazIntfImage.Create(0,0);
  ImgFormatDescription.Init_BPP32_B8G8R8_BIO_TTB(30,20);
  ScanLineImage.DataDescription:=ImgFormatDescription;


   MyBitmap.LoadFromIntfImage(IntfImage);

 Why not loading from ScanLineImage ?


I change several images and load since ScanLineImage directly, there is
plenty of evidence of previous file

   Canvas.Draw(10,10,MyBitmap);



 I think ths should work.


Yes, but not transparency!

 The problem is that I have no transparency with this method.
 
  How to give transparency to MyBitmap?
