[Openexr-devel] Deep Frame Buffer

[Brendan Bolles]

Here's the description of a deep frame buffer from ImfDeepFrameBuffer.h:

// Memory layout:  The address of sample i in pixel (x, y) is
//
//  base + (xp / xSampling) * xStride + (yp / ySampling) * yStride
//       + i * sampleStride


But this is wrong, isn't it?


Shouldn't it be something like:

The address of a pointer to an array of samples for pixel (x, y) is 

**samples = base + (xp / xSampling) * xStride + (yp / ySampling) * yStride

And then a particular sample i is at:

*samples + i * sampleStride
