Using the data storage type defined [[Basic_bitmap_storage|on this page]] for raster images, delegate writing a JPEG file through a '''pipe''' using the <tt>output_ppm</tt> function defined [[Write_ppm_file|on this other page]].
There are various utilities that can be used for this task, for example: '''cjpeg''' (package ''"jpeg-progs"'' on Linux), '''ppmtojpeg''' (package ''"netpbm"'' on Linux), '''convert''' (from ''ImageMagick'', multi-platform).
