.TIF to .png Conversion Sometimes Mirroring Images
Posted: 2014-02-19T05:14:22-07:00
I'm running a batch script which recursively runs through a directory tree, and upon finding .TIF files:
Those are the four commands I'm using, rotating where the original's dimensions indicate the file is landscape and applying less compression when the file size is under a threshold.
Does anyone have any ideas on where imagemagick is getting confused?
EDIT:
Further testing has revealed that this is something to do with the file itself - even cutting down the command to the below, some files are still being mirrored and flipped vertically!
EDIT 2:
Oh, "-quiet". That was silly of me, but I used it to hide a bunch of "Unknown field" warnings that didn't seem to affect anything. Looks like I should have tested this on a larger number of individual files in the first place...
Here's my test program: (the structure is just so to match the main program as closely as possible)
And here's the result...
"Depreciated and troublesome old-style JPEG compression mode". I suppose that means there's no way around this? I'll look at detecting that error somehow (or detecting those files) and do something different in their case...... Bah! Bloody scanners!
Final EDIT:
So, any operation on any image that throws that error will causes it to mirror weirdly. I was hoping adding the raw .TIF to the .pdf would work, but nope. I can't think of a way around.
Okay one more EDIT:
EDIT (....and he just kept talking...):
I will try upgrading to 6.8.8-7 :\
If it's fixed I'll be super happy, but I suspect it's more the dodgy compression than IM's handling...

Didn't help. Sadness.
- Converts any .TIF files into .pngs via a couple of different commands based on the original file's size and dimensions
- Packages up all those .pngs into a .pdf and deletes them
- Zips the .pdf using 7zip
Code: Select all
convert -quiet "%1" -rotate 90 -resize "800x" -type Palette -quality 95 -alpha off "%apath%\%~n1.png"
convert -quiet "%1" -rotate 90 "%apath%\%~n1.png"
convert -quiet "%1" -resize "800x" -type Palette -quality 95 -alpha off "%apath%\%~n1.png"
convert -quiet "%1" "%apath%\%~n1.png"Does anyone have any ideas on where imagemagick is getting confused?
