It curently states that 1.6.1 is the current stable release. The release announcement for 1.7.0 in 2010 said: "The aim is to make an official stable release, 1.7.1, once any outstanding issues have been resolved." Is this still planned? I see that e.g. Fedora or Suse are shipping 1.7.0. thnks, cu andreas </pre> Andreas Metzler 2012-04-09T13:10:23 http://comments.gmane.org/gmane.comp.video.openexr.devel/2406 <pre>Hi, I’m looking to use OpenEXR library through Adobe AIR Application. I saw within the download section that some pre-compiled version are there for Windows. Is there any “pre-compiled” for MacOS. I ask because I plan to create application that will work also on MacOS and iOS (iPad), but actually I’m programming in Windows environment and I don’t directly have access to a Mac Computer. Thanks for your help. Martin Côté, M. Arch. TRIADE MEDIA INC. 2208, rue de l'Équateur | Montréal | Québec | H4R 0H4 www.triademedia.ca Ce courriel est confidentiel.

While working on Avatar I used the system setup at Weta and can see the benefits of such a system. Do you have any idea of the sort of IO load that a full frame semi transparent volume would put on a system? I imagine that it would be fairly comparable to a deep shadow map of the same resolution. I would be more than happy to help with some testing. I am able to compile and render out of Mantra and 3delight and composite in Nuke on CentOS. Sam </pre> sam< at >hodge.net.au 2012-02-27T22:59:45 http://comments.gmane.org/gmane.comp.video.openexr.devel/2384 <pre>I know we haven't made it official yet, but I see that a couple of people have already found the openexr repository up on github. Piotr and I are still working on the details of how the repository is laid out, as well as how the commit workflow is going to work to keep the public repository history clean. I see that there's a couple of forks up there, and I'm sure that a few people have their own clones, so apologies in advance if the reshuffling causes anyone any trouble. In particular one of the main changes I'm going to do is to go back to the import that has the sample images split off into a separate repository to help keep the clone sizes smaller. -nick _______________________________________________ Openexr-devel mailing list Openexr-devel&lt; at &gt;nongnu.org https://lists.nongnu.org/mailman/listinfo/openexr-devel </pre> Nick Rasmussen 2012-02-24T01:35:23 http://comments.gmane.org/gmane.comp.video.openexr.devel/2383 <pre>Hello, I've been playing around with creating a cmake based build for the libraries and stumbled over a little problem when running the generators (eLut.cpp, toFloat.cpp) under Windows from a build rule: the generated eLut.h was empty. Attached patch fixes the problem for me, by flushing cout at the end of the program [1]. Cheers, Carsten [1] I don't know if the C++ runtime is supposed to do this automatically, but it seems not to do it on my system (Windows 7, 64 bit, VS 2010). _______________________________________________ Openexr-devel mailing list Openexr-devel&lt; at &gt;nongnu.org https://lists.nongnu.org/mailman/listinfo/openexr-devel </pre> Carsten Neumann 2012-02-24T00:04:45 http://comments.gmane.org/gmane.comp.video.openexr.devel/2377 <pre>When I specify for example a data window such as (-70,-154)-(649,331) for a 720x486 image and then call writePixels(486), the library is crashing down in copyFromFrameBuffer(). Perhaps this is the way I am adding Slices to my frame-buffer? for (int i = 0; i &lt; channels; i++) { const half *pixels = pixPtr + i; frameBuffer.insert(chanName, Slice(HALF, (char *)(pixels), sizeof(half) * channels, sizeof(half) * width * channels)); } I am basing this on "3.2 Writing a Cropped Image" in the reading/writing document. Though my RGBA pixels are packed into a single buffer. What am I doing wrong? </pre> Paul Miller 2012-02-13T21:16:43 http://comments.gmane.org/gmane.comp.video.openexr.devel/2367 <pre>Does anyone have a binary release of exrviewer for Windows? I haven't built it since v1, and this might be quicker than going through the 87 steps of gathering all the dependencies and building everything in the right order/place. I've got CG DLLs so juse the .exe would be fine.

I tried to recompile OpenCV with the OpenEXR source as a bit documented here: http://opencv.itseez.com/doc/tutorials/introduction/windows_install/windows_install.html#windows-installation However I was not able to build all the OpenCV dll, especially I couldn't build opencv_highgui231.lib. I suspect something in the instructions for building OpenCV with OpenEXR support is not up to date. Do someone know where I could find detailed working explanations about this.

Maybe using MMX, SSE or AVX instructions? </pre> Florian Kainz 2011-07-19T18:19:05 http://comments.gmane.org/gmane.comp.video.openexr.devel/2340 <pre>Hi, in my efforts on using the openexr I spottet a bunch of 'warning C4018: '&lt;' : signed/unsigned mismatch' warnings (with VS 2010 64 bit). All of them in the ImathMatrixAlgo.cpp file. Appending you find a patch which should solve this issues (applied to the openexr-IlmBase project). I would appreciate if someone could add this to cvs, since it means hundreds of output lines less during compilation.
