Hi, First I have to say, this is a pretty cool tool! Thanks for that.

I have an issue with the file size of the png images. They are about 25 MB and they should be about 40 kB. Is there a solution for this? I've been messing about with the imgen.go file and put in BestCompression but this doesn't solve the file size.

Looking forward to hear from you!

usually all NFTs go to an API because of instant reveal .... and file permissions. .idea because I use Goland and some formatting that happened when I pressed save lol

Looks like the weight and height property of nftool images doesn't adjust output dimension.

For example, the traits all have 3000x3000 dimension, but I want the output to be 1080x1080 to save size.

Specifying 1080 for height and weight in nfttool images gives distorted images. It works fine when the orig dimension is provided (3000).

Does the library support this?

❤❤❤❤❤❤❤ Hi, I was trying to generate arts with the exact weights, finally, I found this module and tried. But I was a bit surprised because I didn't see the result that I wanted.
