I am trying to create an image generator and I don't know how to
"merge" the images into one and save it in a transparent png.

Could someone please guide me?

I need to get the images of 4 "TImage" called: Card, Texture, Ribbon,
Picture.
In addition to the 2 texts (TLabel)


I tried creating a "canvas" but I did not know how or I think it is to
draw geometric figures.

It depends if you have half-transparent pixels or if pixels are either
opaque or transparent.

If you don't have half-transparent pixels, then you can use a
background color like clFuschia and define it as the transparent
color.
