Hello,
a simple example (white image) created with gimp on Debian Testing is attached (640Bytes) . With same effect as described in original report:
$> ./fixit_tiff -c -i ~/Dokumente/white_gimp.tiff
infile='/home/romeyke/Dokumente/white_gimp.tiff', outfile='(null)'
these tags are required:
[*] means: tag already exists
### tag 256 (0x 100) [*]
### tag 257 (0x 101) [*]
### tag 259 (0x 103) [*]
### tag 262 (0x 106) [*]
### tag 273 (0x 111) [*]
### tag 277 (0x 115) [*]
### tag 278 (0x 116) [*]
### tag 279 (0x 117) [*]
### tag 282 (0x 11a) [*]
### tag 283 (0x 11b) [*]
### tag 296 (0x 128) [*]
### tag 258 (0x 102) [*]
##### found=12 required=12
tiff comes with all required tags for baseline rgb
tiff is not a baseline, because it has additional tags for baseline rgb
these tags are allowed only:
tag count=19, [*] means: tag is a baseline tag
tag 254 (0x fe) [*]
tag 256 (0x 100) [*]
tag 257 (0x 101) [*]
tag 258 (0x 102) [*]
tag 259 (0x 103) [*]
tag 262 (0x 106) [*]
tag 269 (0x 10d)
tag 270 (0x 10e) [*]
tag 273 (0x 111) [*]
tag 274 (0x 112) [*]
tag 277 (0x 115) [*]
tag 278 (0x 116) [*]
tag 279 (0x 117) [*]
tag 282 (0x 11a) [*]
tag 283 (0x 11b) [*]
tag 284 (0x 11c) [*]
tag 296 (0x 128) [*]
tag 324 (0x 144)
