Re: [Oiio-dev] iprocess unable to resize OpenEXR Half types?

2011-09-06 Thread Larry Gritz
How important is it to you to be locked to 0.10?  In the development trunk, we 
have iprocess being rapidly made obsolete by oiiotool, so I'm a little hesitant 
to put any work into fixing iprocess.

 Hi,
 
 Using oiio 0.10.2, I am unable to resize an image:
 
 iprocess z.exr --resize 32 32 -o out.exr
 
 fails with an 'assertion' at line 357 of iprocess.cpp
 
 
 I'm assuming this is due to the files being half float and not 32 bit
 float, is this expected?
 
 Thanks
 
 Kevin

Larry,

well I was trying to use as close to a stable release as possible, oh
and we don't use git, so I didn't want to track some development
stream in a tool I'm not familiar with, but if you can recommend a
revision to work from then I'm ok with trying it.

In particular if the core IO parts are stable but the tools are less
so, that is something I can OK for the rest of the team to work from,
as they are interested in file IO mostly. We're also interested in
working with OpenColorIO, if that impacts anything at all.

Thanks,

Kevin

Re: [Oiio-dev] iprocess unable to resize OpenEXR Half types?

2011-09-06 Thread Larry Gritz
FYI, I'm thinking that the OIIO release plan is as follows:

VERY SOON, I will commit the last scheduled API change for OIIO core (allowing 
channel subsets to be input) and then branch to enshrine that in a stable 
Release 0.11.  That will also contain all the other recent fixes in the trunk, 
including the presence of oiiotool and deprecation of iprocess.

At that point the master trunk will be, we hope, the path to an official 1.0 
release.  The most important thing I want in 1.0 (and possibly the only thing 
to alter the API further in that time frame) is integration of OpenColorIO.  
Once that's done, I'd like to finally call it 1.0 and again create a stable 
release.

In a very similar situation to OCIO, OIIO has been in production for years and 
is very mature, but we've always hesitated to call it 1.0 because there was 
always one more thing we wanted to squeeze in that might break the APIs.  But 
now we truly are down to just one more thing that would have a big impact on 
the APIs -- OCIO.  In truth, it will have little or no impact on the core APIs, 
probably will only affect some of the utility functions and how the viewer 
works.

 we're looking to get that done this fall, once OCIO hits a 1.0 release
 (hopefully just a few weeks away).
