I'm wondering if anyone has any idea how to get better results from PIL's rotate() function? No matter what filter I use I'm getting very jagged edges after rotating an image.
Here's how I'm invoking the filters: pic = pic.rotate(random_rotation, resample=Image.NEAREST, expand=1) pic = pic.rotate(random_rotation, resample=Image.BILINEAR, expand=1) pic = pic.rotate(random_rotation, resample=Image.BICUBIC, expand=1) # the best I think I posted a sample app that opens an image and rotates it using each of the filters. You can see the jagged edges pretty plainly. I have a slideshow app that I'm working on where these edges are very obvious, so I'm wondering if anyone might have any tips on getting better results from rotate(), or from some other method or module that might do a better job? My very simple sample app that tests each of the filters is here: http://sinkingsensation.com/stuff/rotation_test.zip
