I cannot export a list of images (or a single image) to GIF format. I use Win10 with Mathematica 9.0. It previously worked on an other device with Win7. I can also export an image to other formats, like PNG or JPG.
Export["file.gif",image] produces an output which cannot be opened with anything (Windows Images, Paint, or any browser, ...). Export["file.png",image] works well.
Sorry if it's a common problem, but I haven't found an answer here.
An example code:
image = Plot[x, {x, 0, 1}]; SetDirectory[NotebookDirectory[]]; Export["file1.gif", image] Export["file2.jpg", image]
Image[...]and removing the alpha channel, then exporting it.image = RemoveAlphaChannel[Image[Plot[x, {x, 0, 1}]], White]$\endgroup$
