What am I trying to do:
I want to give the user the ability to upload a picture of any size. Then this image changes if it exceeds 1024 or above 768. Then it resizes the image within these boundaries, but retains the proportions. Then it adds a translucent watermark to the lower right corner and saves the file.
Before he adds the watermark, he will create a copy of the image and resize it to the size of the thumbnail (also keeping the proportions) and save it in a separate folder.
Problems with PIL:
Regarding resizing, I was hoping he would have a way to do smart resizing (keep proportions). In addition, I did not have much control over the quality level while saving it as a JPEG. I had to save it as PNG in order to maintain full quality, which was pretty heavy.
For a thumbnail, it seems like it can be quite difficult to read the PIL documentation, but I could be wrong.
Question
Are there any other, more advanced image libraries for Python that might be a little more relevant or include some of the features I'm looking for? Are there any public functions that perform what I'm looking for that I could use? I do not mind writing this material myself, but I want to check first. Thank!
