The Windows 1.x variant of the CUR format is used in Microsoft Windows versions 1 and 2 to define mouse pointer shapes. It has little in common with the CUR format used by Windows 3 and above.
Format
Files begin with a little-endian word, which is one of:
| Value | Meaning |
|---|---|
| 0003 | Device-Independent Format |
| 0103 | Device-Dependent Format |
| 0203 | Both formats |
This is followed by a 12-byte header describing the cursor bitmap:
| Offset | Type | Meaning |
|---|---|---|
| 0000 | WORD | csHotX, X-coordinate of hot spot |
| 0002 | WORD | csHotY, Y-coordinate of hot spot |
| 0004 | WORD | csWidth, width of bitmap in pixels |
| 0006 | WORD | csHeight, height of bitmap in pixels |
| 0008 | WORD | csWidthBytes, width of bitmap in bytes |
| 000A | WORD | csColor, cursor color |
Two bitmaps come after the header, each csHeight * csWidthBytes bytes long. The first bitmap is ANDed with the screen pattern; then the second is XORed on top of it.
If the file is in 'Both formats' format, the cursor header and bitmaps will then be repeated.
