[Openexr-devel] how to properly save with data window?

[Paul Miller]

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 < 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?
