I am trying to save a GIF image in Photoshop cc. I want it to match other GIF's previously created from another computer. Is there a way to view the way in which these other images were saved so that I can match my own GIF to match them. I am refering to all the photoshop options with you save an image for the web (perceptual, selective, adaptive, diffusion, dither, etc.).
GIF doesn't store any meta information nor are the algorithms used for dithering actually part of the GIF image format. It's merely a means of achieving a better distribution of the limited color palette, but has to be built into the program creating the GIF. Therefore there is no way to determine which exact settings were used after the fact.
Thanks for the response. Maybe you can help me with this then. I am getting a white line around my image when i save it as a gif. I have tried setting the matte to background, but it doesn't seem to be working. Have any advice for that?
