Problems loading DPX format
Closed, InvalidPublic


It has been a while since I last worked with dpx files, so imagine my surprise when I tried to load one and Blender couldn't do it?! Trying to load a dpx returns this in the console:

no image!
IMB_ibImageFromMemory: unknown fileformat (/home/san/Pictures/Airport_011L2_Green_003.dpx)

I've attached a zip containing 3 images:

Airport_011L2_Green_003.dpx = standard 10bit dpx frame
blender_dpx_save.dpx = Blender render saved to dpx
iv_dpx_save.jpg = the result when opening that render dpx in 'iv' (oiio viewer)

Blender can open its own dpx fine, and the render also show up fine in 'display' (Imagemagick) but as you can see something weird happens in 'iv'. The Airport dpx works as expected in both 'iv' and 'display' and other dpx capable apps, but Blender won't eat it.

Tested on:
Fedora 17 64bit
Blender-SVN r51272



We've got patch which updates DPX/Cineon file import/export there
It solves the issue.

Checked the patch, updated it to current trunk. Think it's pretty ok to go to svn. Brecht, Campbell -- any ideas?

Sergey: go ahead, we are now in bcon1 still so things can always be tested well.
The developer of this code should be emailed to find out if he can be around though.

Ejner: our DPX code was copied from CinePaint, back in early 2008. It was already old then. :)

The patch has been applied in svn rev51495, so the report should now be finally solved.
