Re: [Openexr-devel] Problem with deep data

[Piotr Stanczyk]

What kind of differences are you seeing? Is there a potential color space conversion you are seeing? 

You could visualize the data in Nuke or the native (FLTK alas) viewer

I have been attempting to add a deep-data part to a multipart file. Everything compiles and runs, but the data I read back from the file do not match in any way the data I wrote to the file.  I have tried simplifying as much as possible and stepping through the code in a debugger.

(BTW, the description of DeepSlice's memory layout in ImfDeepFrameBuffer.h is wrong.  It doesn't describe the layout of pointers to arrays of samples.)

It looks to me like all my pointers are correct, but the data returned by Xdr::read() are not the data I sent to Xdr::write(). The headers look fine, and the RGBA image looks fine, but the deep-data part is not.

I have been using version 2.2.0, but I also tried 2.2.1 with no success.

Has anyone had similar problems with deep data?  How can I debug this failure?
