Hello, I’m brand new to the forums here. I’m okay at actionscript, but honestly everything I’m trying to pull off is beyond me so the fact that I’ve gotten as far as I have is kind of a feat in itself. Anyway, I’m creating a dynamic image gallery that resizes the images to fit the gallery size, and then smooths them out.
I feel like I’m super close to getting it to work perfectly. The image smoothing always works, but the resizing is kind of iffy. The first image displayed will resize just fine, but when you view any others they’re all distorted or squashed. What’s strange is that I’ve traced out the resized image dimensions and they’re exactly what they should be, but the images are still not resizing correctly.
Here’s my code! I only included the parts of it that are really relevant, but let me know if you guys want to see all of it. It’s a combination of a few tutorials that I found. I may be able to provide a live example, but it’s for work so I’m not sure how the nondisclosure agreement would affect that.
Thank you so much in advance!
