# Objective
When using a rect for a ui image, its content size is still equal to the
size of the full image instead of the size of the rect.
## Solution
Use the rect size if it is present.
## Testing
I tested it using all 4 possible combinations of having a rect and
texture atlas or not. See the showcase section.
