ROM Hack Fire Emblem Awakening Custom Portrait Problem

[JeiM.]

Hi, I recently began hacking Fire Emblem Awakening using its romfs. Right now I'm attempting to change Anna's character picture with a new custom character. I'm able to compress it into a ctpk file with the new image and the xml file in there but when I decompress it the image comes out distorted. I used the same dimensions and even bit depth as the original but it still distorted when compressed and decompressed. Any ideas. Here are some images for reference before and after.

Don't bump your threads. Someone will reply when they do.

But you're still able to inject it?
