Hi so I’ve been doing my rough line work in flipaclip then transferring them to my drawing app to line again and add color. I have realized that I have this issue that the image inserted will change size? I did set my canvas size on the drawing app to the exact same as my flipaclip canvas size, but the image just comes out bigger? I also cannot adjust it properly since adjusting manually will warp the image :/ anyone knows how to fix this? Thank you :3
