Loading an animated GIF
In order to load and edit an animated GIF file with mtPaint, your system must have Gifsicle installed. If you don't have it already you can download it HERE.
When you attempt to load a GIF file that has several frames, mtPaint will detect this and give you a message to ask if you want to edit them. If you do, then mtPaint will prompt you for a temporary directory to store these frames in. It is advisable to create a new folder (via the file selector) near the original GIF file for easy navigation.
After Gifsicle has created these frames, a new mtPaint process will be started with the frame filenames in the command line window. You click on a frame filename and this will be loaded so you can edit it as a normal image.
Once you have finished editing the frames and you want to create the new animation file, select 'Export GIF animation' from the file menu to bring up the file dialog. The frame delay box sets the delay in 1/100ths of a second between each of the frames. This value should be remembered from when the animation was loaded, but it may not be accurate if the input file has several different delay values. In the filename box enter the new filename e.g. 'new.gif' and then save the file to your preferred location.
