Comment (by Michael Koch):

 Replying to [comment:3 Jozef Chutka]:
 > Hi Michael,
 > please check the attachments I included. I am trying to mask semi
 transparent image containing "X" by mask in "O" shape.

 Your image main.png (which contains a green X over a black background)
 can't be semi transparent because it has no alpha channel. The pixel
 format is rgb24.
