[Image-SIG] saving an image with EXIF data

I notice that when I open an image with PIL, manipulate it, and resave it, the EXIF data is lost. This can be a major pain, particularly with regards to image orientation -- is anyone aware of a way to feed exif data back in to the Image.save() method? Thanks! Eric __

Re: [Image-SIG] Array to Image transformations

There are currently two PEPs related to this kind of problem. One is lead by Travis Oliphant of numpy and is about establishing a buffer protocol for data interchange. The second one is specifically related to passing image data between applications/toolkits. http://www.python.org/dev/peps/pep-311

[Image-SIG] problem with PIL's Image.save() on TIFFs

Hi, I've just had some problems with PIL's implementation of the Image.save() method when writing TIFF files. Apparently some internal tags on resolution are totally out of the normal. Using the TIFFs from libtiff later on produces some warning on a tag with bad information. This is what libti
