Re: [Openexr-devel] Trouble creating deep scanline files

[Halfdan Ingvarsson]

At first glance, it looks like your x and y indices are reversed.

The outermost bracket increases fastest and should therefore be indexed by x.

E.g:

Imf::Array2D<unsigned int> sampleCount; sampleCount.resizeErase(yRes, xRes);

...

for (int y=0; y < yRes; y++) {
   for (int x=0; x < xRes; x++) {
      sampleCount[y][x] = sampleSize;
...
   exrFile.writePixels(1);


Hope that helps,

Good morning folks!

I'm trying to convert deep rat images into OpenEXR deep scanline images using the current 2.0.0 release on openexr.com.

At this point I haven't been able to create a valid file and I am at a loss to understand why. 

Here is a super simple test based on the documentation and it doesn't create a valid file: http://hastebin.com/webasetiyo.cpp

Does anyone see anything blatantly wrong with this? Any advice would be helpful!

Thanks,

Chip
