Which value for the ZIP compression does Adobe use? Where on the Net is possible (if it is) to find Rev. 7?

Thanks,

Ivo

Libtiff uses a Compression value from the private range for ZIP compression - that's all that Sam could do without Adobe's official

blessing. The actual TIFF 7 spec uses a Compression value from the "official" range for Deflate compression. Adobe's ImageReady uses the official value, since its developers had the benefit of the real spec.
