The output file name is the input file name extended with "-nq8.png" or a specified extension….
PNG driver – driver to create PNG and PPM images (drivers) DescriptionThe PNG driver generates PNG and PPM images from GRASS display commands. Per default PNG files are written with this driver. It is started as ‘pseudo’ monitor (image file instead) and when stopped, all output from previously used display commands are written to the…
png2yuv – Convert PNG images to the YUV4MPEG stream format. Synopsispng2yuv [-b num] [-f num] [-I num] [-L num] [-n num] [-l num] [-j filename] Descriptionpng2yuv decompresses a sequence of PNG files and pipes the image data to stdout as a YUV4MPEG2 stream. Any 8bit/pixel PNG format supported by libpng can be read. stdout will…

pmxchords – This script processes pmx files with chord symbols, allowing for key transpositions Synopsis[ texlua ] pmxchords { option | jobname [ .pmx ] } … The default effect is to preprocess each pmx file so that chords are transposed as necessary, generating a temporary pmx file which is then processed by pmxab. Finally…
pmxab – a MusiXTeX preprocessor Synopsispmxab basename[.pmx] Descriptionpmxab is a preprocessor for MusiXTeX. It’s usually invoked by a frontend musixtex(1). To use it to its full benefit you should have installed MusiXTeX Version 1.21 or higher, and TeX itself. The goal of PMX is to faciliate the efficient typesetting of scores and parts that have…
