OPut of memory during HDR composition

[federico]

Hi,
HDRComposition continues to fo out of memory, but PI is the only program running, plenty of memory available.
WinXP 32 bit - 4 GB of memory, max occupied by PI duiring session: 840MB.
There are only 2 images, and both have been processed by Histogram

Hi Federico,

This happens with the old HDRComposition script. You should use the new HDRComposition tool, which you'll find under the ImageIntegration category, on the Process Explorer window. This tool works much better than the script and does not have these memory consumption problems.
