So on popular demand by one potential user here it is http://scdbackup.sourceforge.net/halve_jpeg.c SHA256SUM: b4c9322cd7d20a09a5196ccbcec257bf363d9dea1284333afc9624ff6a05dcc0 It needs installed libjpeg development header files and runtime library. To my theory that would be package "libjpeg62-turbo-dev" which brings the runtime as dependency. The tools for compilation get installed by meta-package "build-essential". Compile the program by cc -g -Wall -o halve_jpeg halve_jpeg.c -ljpeg Test by converting some file ./halve_jpeg -geometry 1280x1024 large_input_pic.jpg ermerging_small_pic.jpg xv ermerging_small_pic.jpg The -geometry argument defines a frame into which ermerging_small_pic.jpg will fit while retaining its x:y ratio. For permanent use, copy the file ./halve_jpeg to a directory where the shell will find it. It is not very good with enlarging images. My motivation was to condense JPEGS with zillions of pixels to screen size without blasting my RAM which was only 2 GB at that time. Have a nice day :) Thomas
