Symptoms
When running an application that makes use of one or more of the Impact Acquire internal image processing algorithms (e.g. the Bayer filter) in an environment were a lot of memory is allocated and freed frequently on the heap and memory resources are limited (e.g. when running a 32-bit process) bad_alloc exceptions are thrown from within Impact Acquire after some time.
Cause
By default the image processing algorithms of Impact Acquire is configured in a way that memory is allocated as needed and freed as fast as possible thus when not needed any more. This reduces the memory footprint to a minimum but when a lot of other small or large allocations on the heap take place as well this might result in a fragmented heap. After some time this might result in the heap being fragmented to such an extend that buffer needed to convert images as a whole can no longer be allocated. In such a case the C/C++ runtime library might raise a bad_alloc exception.
Resolution
Impact Acquire addresses this problem by the introduction of the property ImageProcessingOptimization
The effects of this property are described here: Image Processing.
