Convert PALM to PGM

The PALM file extension, standing for Palm Pixmap, is a bitmap image format used by Palm OS mobile devices. It stores logos, clipart, photos, and other images for display in Palm OS applications. Originating from the now-discontinued Palm OS, the PALM format evolved through several versions, with later iterations supporting transparency and run-length encoding compression. PALM files are compatible with various operating systems, including Windows, Linux, and Mac OS, and can be opened and converted using tools.

The Portable Graymap (PGM) file extension, originating in the late 1980s as part of the Netpbm project, stands for "Portable Gray Map". It serves as a simple, versatile format for grayscale images, enabling easy reading and writing by various programs. Due to its straightforward structure and plain text encoding, it's often used in academic and research settings where ease of parsing and accessibility are crucial. PGM files store grayscale images in a compact, efficient manner, making them an essential tool for image processing tasks.
