Convert PAM to PSD

The PAM (Portable Arbitrary Map) file extension is a versatile bitmap format used primarily in UNIX-based systems. It extends the Portable Any Map (PNM) format, supporting 2-dimensional image data storage in a binary format with an ASCII header. Introduced to enhance flexibility and interoperability in image processing, PAM files are utilized for various graphical applications, offering a standardized method for handling diverse image types. This format's history traces back to the need for a more adaptable and comprehensive bitmap solution within the PNM family.

The PSD file extension stands for Photoshop Document, which is the native file format for Adobe Photoshop. It is primarily used to save graphics and images, preserving layers, masks, transparency, and other editing features, allowing for non-destructive editing. Introduced in 1988 with Photoshop's first release, PSD files have since become a standard in the graphic design and digital imaging industry due to their flexibility and support for various color modes and channels, including RGB, CMYK, and grayscale.
