pnmtorle

Convert a PNM file to an Utah Raster Tools RLE image file. More information: https://netpbm.sourceforge.net/doc/pnmtorle.html.

• Convert a PNM image to an RLE image:

pnmtorle {{path/to/input.pnm}} > {{path/to/output.rle}}

• Print PNM header information to stdout:

pnmtorle -verbose {{path/to/input.pnm}} > {{path/to/output.rle}}

• Include a transparency channel in the output image in which every black pixel is set to fully transparent and every other pixel is set to fully opaque:

pnmtorle -alpha {{path/to/input.pnm}} > {{path/to/output.rle}}
