PGMA Files - ASCII PGM Files (Portable Gray Map)
- PGM is a storage format for grayscale images. Files in this format can be opened using software: ACDSee Photo Manager 14, ACD Systems Canvas 15, Corel PaintShop Pro X4. This type of file can be edited with a text editor. PGM files can be in two versions: P2 / P5. P2 are readable, P5.
- These files can be saved in two representations, either as plain (ASCII) text or binary. In which way the PGM is saved is apparent in the file header. If the header contains the string 'P2' it is a text format, if it contains the string 'P5', it's a binary representation. Binary PGM files can contain more than one image. This is not possible.
PGM files consists of grid of numbers from 0 to 65 536 that represent different shades of gray. PGM file header defines the type of image representation (text or binary) and image dimensions. PGM files can be converted into other image formats using a dedicated tool, for example multiplatform application Netpbm.

Is there one way to open unknown files?

It is possible that while opening unknown files (e.g. PGM) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
