PNM Files

These are some examples of PNM files. "PNM" stands for "Portable Any Map" and is intended to cover all six variations of Jef Poskanzer's portable bit/gray/pixel maps, (PBM, PGM, and PPM) whether ASCII or binary.

PNM files are:

• ASCII (P1, P2, P3) or binary (P4, P5, P6)
• B/W (P1 or P4), Gray (P2 or P5), or Color (P3 or P6)
• 2D
• No compression
• 1 image

Reference:

Programs to view a PNM file include:

• The AVS module read_any_image can read a PNM file.
• XV

Programs to convert a PNM file to another format:

• GIMP can read a PNM file and write out a copy in a variety of formats.

Programs to convert a file to PNM format:

• GIMP can read a file in a variety of formats, and write it out as a PNM file.
• pstopnm converts a PS (PostScript) file to PNM form.

Files you may copy (Careful! These are binary files):

• BIRCH.PNM, a texture, type P6 (binary pixels);
• CATHEDRAL.PNM, stained glass, type P6 (binary pixels);
• CHECKERS.PNM, a checkered texture, type P6 (binary pixels);
• COTTON.PNM, a cotton texture, type P6 (binary pixels);
• FISH_TILE.PNM, a texture, type P6 (binary pixels);
• GARNET.PNM, a texture, type P6 (binary pixels);
• GRAVITY_01.PNM, a black hole boundary, type P6 (binary pixels);
• GRAVITY_02.PNM, a black hole boundary, type P6 (binary pixels);
• GRAVITY_03.PNM, a black hole boundary, type P6 (binary pixels);
• GRAVITY_04.PNM, a black hole boundary, type P6 (binary pixels);
• GRAVITY_05.PNM, a black hole boundary, type P6 (binary pixels);
• GRAVITY_06.PNM, a black hole boundary, type P6 (binary pixels);
• GRAVITY_07.PNM, a black hole boundary, type P6 (binary pixels);
• OAK.PNM, a texture, type P6 (binary pixels);
• QUILT.PNM, a texture, type P6 (binary pixels);
