explain the various choices in the TIFF dialog
Submitted by Brian Remedios
The in the v2.2 dialog I find a series of five radio buttons:
() None () LZW () Pack Bits () Deflate () JPEG
First off, I'm not sure why JPEG is listed as the last option when the dialog states "TIFF" at the top. If I wanted to save it as JPEG I shouldn't see this dialog at all.
For the three other LZW, PackBits, and Deflate options I'm not sure which one is appropriate or most compatible with other programs. The dialog needs to provide additional detail for each option, ideally in the form of a table:
Type Lossy Compression File size
None 0% 100K LZW 14% 86K Pack Bits 45% 55K Deflate 12% 88K JPEG Y 75% 25K
The compression/file size column values could be computed in the background with some kind of busy indicator while doing so. Users would then select the row type they wanted before the OK button gets enabled.
