I want to show an apple on screen but the image has a white background and it doesn't blend with the background of a tree.
Is there any image format in which only the red apple is displayed?
.png images wont show the transparent area. But you will have to make sure that the "white" area is transparent and not white.
If its not a .png image just go in to photoshop or any other image editor, cut out (magic wand) the white area and save it as a .png
