Multiple-image Network Graphics
The ambitious, complex, and largely obsolete animated cousin of PNG.
MNG (Multiple-image Network Graphics) was designed as the animated equivalent of the PNG format. Just as PNG was created to replace GIF for static images, MNG was intended to replace GIF for animations, offering superior compression, full alpha transparency, and complex features like nested loops and sprites. However, its complexity led to poor adoption.
MNG is a stream-based format that shares the same chunk structure as PNG. It can contain embedded PNG (lossless) or JNG (JPEG-based) images. Unlike a simple filmstrip, MNG is a scriptable animation format; it supports 'sprites', frame deltas (only updating changed pixels), and complex composition rules.
Published in 2001 by the creators of PNG. Despite high hopes, browser vendors (like Mozilla) eventually removed support due to the large code footprint and complexity of the library (libmng). The simpler APNG format won the browser war for 'animated images'.
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.
