Cannot import tiff with deflate compression

[Ross Gardiner]

When trying to import a deflate-compressed tiff into Inkscape 0.48 prerelease, after selecting whether to link or embed, I get a message saying that Inkscape 'failed to load the requested file'. I believe, although I am not sure, that these files worked in previous versions. LZW-compressed tiffs still work fine.

Platform:
Inkscape 0.48pre1 r9509
Windows XP MCE 32-bit

Can you attach a sample TIFF file that fails to import?

[Ross Gardiner (ross-gmx)]

Saved as TIFF with Deflate compression in the GIMP 2.6.8

[su_v (suv-lp)]

not reproduced with Inkscape 0.47 and 0.47+devel r9587 on OS X 10.5.8

- In both Inkscape versions the TIFF file imports without errors.
- GIMP on OS X 2.6.8 also opens the file without problems.
- Apple's default image viewer (Preview.app, Version 4.2 (469.5)) however fails with the error message "Couldn’t open the file. It may be corrupt or a file format that Preview doesn’t recognize."

@JazzyNico - can you test on linux? Possibly a problem affecting 'inkscape-devlibs' for the win32 port?

I've reproduced this bug ('failed to load the requested file') the first time I've imported (embedded) the file on Ubuntu, Inkscape r9582, but now I can't reproduce it, even after restarting Inkscape!
I'll try again on Windows XP tomorrow.

When embedding the TIFF file (r9587), and realigning it after changing the page size, I get the same console warnings as in bug #597689:

** (inkscape-bin:61531): WARNING **: GC Warning: Repeated allocation of very large block (appr. size 15503360):
 May lead to memory leak and poor performance.

Confirmed on Windows XP, Inkscape 9535, but not reproduced with 0.47.

I still can't reproduce it on Ubuntu. I guess the file was not completely downloaded when I first tried to import it.

[jazzynico (jazzynico)]

Reproduced again on Windows XP, Inkscape trunk revision 13279, official devlibs.
Not reproduced with the experimental GTK3 devlibs, same OS and Inkscape version.

[Alvin Penner (apenner)]

on Windows XP, Inkscape trunk revision 13245, official devlibs, I get the console messages.

(inkscape.exe:3984): GLib-WARNING **: GError set over the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
The overwriting error message was: Couldn't load bitmap
GdkPixbuf loader failed

[jazzynico (jazzynico)]

New tests with recent libtiff libraries (tested with 3.9.7 and 4.0.6) still don't work on Windows XP (32bit). Very likely a GdkPixbuf loader issue...

[jazzynico (jazzynico)]

And probably a duplicate of (or strongly related to) Bug #1153777 "Import cmyk-tiff crashes".

[jazzynico (jazzynico)]

Bad new, we already have the most recent gdk-pixbuf version that is compatible with our glib package, and thus there's nothing we can do for now except recompiling almost the whole devlibs.
