pnmmontage — Create a montage from multiple PNM images. More information: <https://netpbm.sourceforge.net/doc/pnm

Produce a packing of the specified images

pnmmontage {{path/to/image1.pnm path/to/image2.pnm ...}} > {{path/to/output.pnm}}

Specify the quality of the packing (Note: Larger values produce smaller packings but take longer to compute.)

pnmmontage -{{0..9}} {{path/to/image1.pnm path/to/image2.pnm ...}} > {{path/to/output.pnm}}

Produce a packing that is not larger than `p` percent of the optimal packing

pnmmontage {{[-qua|-quality]}} {{p}} {{path/to/image1.pnm path/to/image2.pnm ...}} > {{path/to/output.pnm}}

Write the positions of the input files within the packed image to a machine-readable file

pnmmontage {{[-d|-data]}} {{path/to/datafile}} {{path/to/image1.pnm path/to/image2.pnm ...}} > {{path/to/output.pnm}}
