You might consider before going further whether what you need to do could be done more easily using a batch conversion software such as the excellent XNConvert. After a lot of Googling, trial and error and great frustration, I eventually developed my own way of working which may be unconventional but sidesteps some of issues I encountered. That really requires a detailed tutorial and sadly I can't immediately direct you to one! Having been down this path myself some years back, I can tell you that it can be a rather steep learning curve without a detailed guide. where do I type the code? Please advise specifically since I'm not familiar with command line software. ![]() Too much information? Try 'J:\ProgsWin\GIFS150K\GIFW.EXE -help | more'. WARNING: Experimental port, pipe coloring and Floyd stuff might not work. ![]() use-colormap CMAP Set output GIF's colormap to CMAP, which can transform-colormap CMD Transform each output colormap by shell CMD. scale XFACTOR Scales the output GIF by XFACTORxYFACTOR. resize-height H Resizes to height H and proportional width. resize-width W Resizes to width W and proportional height. resize WxH Resizes the output GIF to WxH. f, -dither Dither image after changing colormap. color-method METHOD Set method for choosing reduced colors. k, -colors N Reduces the number of colors to N. change-color COL1 COL2 Changes COL1 to COL2 throughout. careful Write larger GIFs that avoid bugs in other l, -loopcount Sets loop extension to N (default forever).

E, -explode-by-name Explode mode, but write 'input.name'. e, -explode Explode mode: write N files for each input, b, -batch Batch mode: modify inputs, write back to m, -merge Merge mode: combine inputs, write stdout. Mode options: at most one, before any filenames. Space, and printing information about GIFs. Single images into animations, adding transparency, optimizing animations for GIFSICLE has a "resize" feature doing all in one step, but uses the "nearest neighbor" algo only - gives bad results except for zooming up with an integer factor. To avoid this problem, one can "merge" the frames into 1 static BMP using XN (not NC ?) before resizing and palettize this one BMP only, and then re-split (but how ? Have to code something ) The problem is that you will get a separate palette for every frame this way (-> bloated GIF). Re-merge with GIFSICLE (or above mentioned UNFREEZE) Re-palettize them using NC/XN, save as GIF Newer smartphone cameras save photos in the HEIC format by default. Resize the frames using NC/XN and appropriate algo (this will convert them into 24bpp True color), save as BMP Converting How to Convert HEIC to JPG with XnConvert By David Coleman Last Updated: JFiled Under: Converting Topics: HEIC, JPG This post may include affiliate links. Extract the frames with GIFSICLE or NC/XN If GIF is "optimized", "unoptimize" it with GIFSICLE (XN can't) Minimal AGIF creation should be rather easy, OTOH "optimizing" is a considerable amount of additional work. > maybe this can be done via xnview batch file somehow? forgot to post download link to my DOS and Win32 ports:
