- Help! It seems LZW image compression under 2.1 is faulty. I have
- encountered several images that won't reopen when saved using LZW,
- like so:
-
- [bitmap writeTIFF:s usingCompression:NX_TIFF_COMPRESSION_LZW
- andFactor:10.0];
-
- I get messages like so:
-
- TIFF Error: LZWDecode: Not enough data for scanline 259 (decode 1249
- bytes).
-
- Has anyone else encountered this, and if so, please tell me there's a
- patch for this under 2.1.
-
-
- Please e-mail me at dylan@angst.com,
- thanks in advance.

- P.S. Has anyone else noticed JPEG under 2.1 has problems saving
- images with large regions of pure red in them? It changes it to green.
