To help me learn a few charts we use at work, I've made a simple skin based on Moshi's picture frames, showing random charts on my desktop. The charts are saved as transparent png files (they blend in nicely on my desktop), in various sizes and size ratios. My skin resizes all images to a with of 400, but gives no value for height.
The funny thing is, my charts seem to be cropped by a random # of pixels at each update. They all have the right width and the right aspect ratio, but the bottom part gets cropped out, by anything between 0 and roughly 75%.
Has anyone else seen this issue? Any tips on a solution?
