About ICON Format

Icon File

A generic, often ambiguous extension for icon resources.

Overview

The `.icon` file extension is a generic identifier for icon images. Unlike the strictly defined `.ico` (Windows Icon), `.icon` is often used in Unix/Linux environments or by tools like ImageMagick as a catch-all alias for various icon formats (including Sun Icon, XBM, or simply renamed ICO files). It is not a standardized format itself but a convention for naming icon resources.

Technical Details

The internal structure of an `.icon` file depends entirely on what created it. It might be a standard Microsoft ICO container with multiple sizes and color depths. It might be a persistent X11 bitmap (XPM). Or it might be a Sun Raster file used for icons on Solaris systems. Because of this ambiguity, it requires a robust viewer that detects format by 'magic bytes' rather than extension.

History

In the early days of GUI desktops (SunOS, IRIX, early X11), there wasn't a single unified icon standard like Windows .ico. The `.icon` extension served as a descriptive label for files intended to be used as desktop icons, regardless of their underlying binary format.

Common Use Cases

  • Generic Resource Labeling: Naming a file `logo.icon` to indicate its purpose in a directory of assets.
  • Legacy Unix Systems: System icons for older window managers.

Advantages

Limitations

  • Ambiguity
  • Web incompatibility

About CUR Format

Microsoft Windows Cursor

The standard format for static mouse cursors on Microsoft Windows.

Overview

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.

Technical Details

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.

History

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.

Common Use Cases

  • Windows Customization: Creating custom mouse pointer themes for Windows.
  • Web Design: Custom cursors on websites using CSS (`cursor: url('pointer.cur'), auto;`).

Advantages

  • Hotspot Definition
  • Multi-Resolution

Limitations

  • Static Only
  • Size Limits
