The images will be named **FrameFile_000.tga, FrameFile_001.tga, FrameFile_002.tga, FrameFile_005.tga**, etc. To specify the frames, an asterisk by itself means all, `0-2` means 0 to 2 (inclusive), the + is used to specify more ranges. The ! means exclude the endpoint, so `!7-10!` would be 8 to 9. A number by itself is just that number as a range. eg. 11 would translate to `11-11`. Since -k is included, InImage.gif itself will _not_ be resaved as InImage.tga. If the input image has fewer frames than the ranges being processed, those frames can't and won't be saved because they don't exist. This is not considered an error. If FrameFile is * or is not entered, the base filename of the input image(s) is used and the frame-number is still appended.
