2003.01.31 16:52 "Opening compressed images in "update" mode.", by Frank Warmerdam
<x-flowed>Folks,
As part of my efforts to improve the ability of libtiff to update existing images in-place, I have removed the restriction in tif_open.c that prevented compressed images from being opened in update mode. I have added a check in TIFFWriteCheck() (called before imagery can be written on a directory) to fail if an attempt is made to write to an existing compressed image.
If anyone knows a reason this will be terrible please let me know.
This should allow updates to directory information of a compressed image without having to copy everything.
If anyone knows a reason this would be really bad, please let me know. The change is in CVS if anyone wants to try it.
