Pyramid TIFF
A multi-resolution TIFF optimized for deep zooming.
PTIF (Pyramid TIFF or Pyramidal TIFF) is a standard TIFF file that has been structured to contain multiple resolution levels of the same image (a 'pyramid'). This allows software to open immense images (e.g., gigapixel maps or medical scans) almost instantly by loading only the low-resolution tile suitable for the current zoom level, rather than decoding the entire massive file.
Inside the TIFF wrapper, the image is stored as a series of SubIFDs (Image File Directories). The main image is typically the highest resolution. Subsequent directories contain the image downscaled by powers of two (50%, 25%, 12.5%, etc.). Additionally, the image data is usually 'tiled' (broken into usually 256x256 blocks) rather than 'stripped'. This enables random access to specific regions.
Developed to handle the exploding size of satellite imagery and digital pathology slides.
X BitMap
Images written as C source code.
XBM (X BitMap) is a unique image format that is actually a valid snippet of C source code. It defines an array of bytes representing a monochrome bitmap. Because it is code, it can be compiled directly into an application binary, which made it the standard for X11 icons and cursors.
An XBM file contains `#define` statements for width and height, and a static array of unsigned chars: `static unsigned char image_bits[] = { 0x00, 0xFF, ... };`. It supports only 1-bit color (black and white). Transparency works by defining a mask.
The original format for X Window System bitmaps (X10/X11). Used extensively in the 90s for the early World Wide Web (Mosaic browser) before GIF/JPEG took over.
