pnmmontage

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

• 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 -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 -data path/to/datafile path/to/image1.pnm path/to/image2.pnm … > path/to/output.pnm
