I need to convert an image from CMYK to RGB in python. I used Pillow in this way: img = Image.open('in.jpg') img = img.convert('RGB') img.save('out.jpg') The code works, but if I convert the same image with Photoshop I have a different result as shown below:- The only operation done in photoshop is to change method from CMYK to RGB. Why there is this difference between the two RGB images? It can be a color profile problem? SOLVED The problem is that Pillow does not know the input ICC profile, while photoshop had one set as default. Photoshop use for CMYK : U.S. Web Coated (SWOP) v2 RGB : sRGB

I'm mapping several photoshop elements to CIFilter, the only one I'm having trouble with is this Levels Adjustment: Which CI Filter (or combination of filters) would let me utilize the 16, 1.73, 239 & 39/245 above in the first example or the 31, 1.25, 255 30/255 in the second example. I believe this is a kind of shadow/black and white level adjustment.

I have a multi-layered PSD, with one specific layer being non-rasterized text. I'm trying to figure out a way I can, from a bash/perl/python/whatever-else program: load the PSD edit the text in said layer flatten all layers in the image save as a web-friendly format like PNG or JPG I immediately thought of ImageMagick , but I don't think I can edit the text layer through IM. If I can accomplish the first two steps some other programmatic way, I can always use ImageMagick to perform the last two steps. After a couple of hours of googling and searching CPAN and PyPI, I still have found nothing

I am looking for a script that would open a given number of images with different aspect ratios and layout them all in a single document like the flickr gallery. Something as seen in this page: http://martin-oehm.de/data/layout.html Is there any script/plugin out there that can do this? The purpose is just to create a reference file with all the images instead of having several images floating around. Thank you The fact that you have had no answers in 10 weeks should tell you that Photoshop is maybe not the best/easiest place to do this.... so, I made the following script that does it pretty

I want to do something similar to Photoshops inner shadow effect in Core Graphics. If I draw/fill a path with this effect, I want get something similar to the following: Here are the layers you need to create to make this image, from back to front: The base color, in this case a white background. The shadow. The shape casting the shadow. This is made by finding the bounding box of the inner shape, expanding that box by more than the width of the shadow, then cutting a hole in the box with the inner shape. Clipping these with the inner shape. Then finally drawing the surrounding colored shape,
