I am preparing some images to animate on mobiles. Basically, I am exporting PNG sequences, with Alpha channel and distributing these images on the Art board.
All this images are 200x200 px. So, if we think, 5 images distributed on the art board it will have 1000x200 px.
The problem is, when exported with alpha, these images lose the properties of 200x200px and the size becomes the place without alpha. When I try to distribute these images on the art board is a mess, because they have different sizes.
How can I keep the default size 200x200px? Should I do some process of Crop area?
