Microsoft Windows Cursor
The standard format for static mouse cursors on Microsoft Windows.
The CUR format is the standard file format for static mouse cursors in the Microsoft Windows operating system. It is structurally almost identical to the ICO (Icon) format, with one key difference: the header contains a defined 'hotspot'. The hotspot specifies the exact pixel coordinate (x, y) that registers the click, such as the tip of an arrow pointer.
A CUR file starts with a header similar to an ICO file, but the 'image type' field is set to 2 (Cursor) instead of 1 (Icon). For each image in the file (it can contain multiple sizes/depths), the directory entry stores the hotspot X and Y coordinates instead of the color planes/bpp fields found in ICOs. The image data itself is typically a BMP with a 1-bit AND mask for transparency, or a PNG in modern versions.
Introduced with Windows 1.0, the format has evolved alongside Windows. Originally supporting only monochrome, it grew to support 16 colors, 256 colors, and finally 32-bit alpha-blended cursors in Windows XP.
Wireless Bitmap
The pixel format of the Nokia 3310 era.
WBMP (Wireless Bitmap) is a monochrome graphics file format optimized for mobile computing devices using the Wireless Application Protocol (WAP). It was designed for the extremely limited bandwidth and display capabilities of early 2000s feature phones.
A WBMP file is an uncompressed sequence of bits with a minimal variable-byte integer header usually encoding generic type (0), width, and height. It supports only 1-bit color (black and white). There is no compression, palette, or gray scale.
Developed by the WAP Forum to deliver icons and simple graphics to mobile phones over 2G networks.
