Photoshop Big
The 'Large Document Format' for managing gigapixel images.
PSB (Photoshop Big) is an extension of the PSD format designed to break the barriers of the 2GB file size limit and 30,000 pixel dimension limit of standard PSD files. It is structurally almost identical to PSD but uses 64-bit offsets inside the file to support massive files up to 4 Exabytes (theoretically) and 300,000 pixels in width/height.
Internally, a PSB file mirrors the block structure of a PSD (Header, Color Mode, Image Resources, Layer and Mask Info, Image Data). The key difference is the bit-width of length integers; PSB uses 8 bytes (64-bit) where PSD uses 4 bytes (32-bit) for describing file offsets and dimensions.
Introduced in Adobe Photoshop CS (v8.0) in 2003 to support the growing needs of astronomical imaging, billboard printing, and HDR photography.
X PixMap
Color icons written as text.
XPM (X PixMap) is the usage successor to XBM. It allows for color images (and transparency) to be stored as C source code arrays. It was the standard format for icons in the Common Desktop Environment (CDE) and many Unix window managers.
An XPM file is valid C code defining a character array: `static char * icon[] = { ... }`. The data defines a color palette (mapping characters like '.' or '#' to hex colors) and then draws the image using those characters. This makes it human-readable and editable in a text editor.
Developed by Groupe Bull in 1989 to bring color support to X11 icons.
