Memory Issues with Very Large Image Files

If you are working with very large image files and are experiencing errors or crashes on a Windows system, this could be caused by a low-memory situation. For example, you could find that executing a save() for a 50,000 x 40,000 pixel image after a colorize() with selection() and other operations results in a write error. Such a process requires 8,000,000,000 bytes of memory, and this example would require three rasters of that size to be in memory at the same time.To accommodate this, the system would need 24,000,000,000 bytes, in addition to the operational memory requirements of MediaRich and Windows.

Important:  There is NO indication of a low-memory situation caused by something that was done BEFORE the save().

» Check that the automatic scale-down settings are enabled in the Global Properties of the MediaRich CORE Server.

With the default settings enabled, MediaRich downsizes TIFF, JPEG, and Photoshop files to a max of 8192x8192 at loading. It is possible that this was disabled.

For more information about setting MediaLoadMaxHeight and MediaLoadMaxWidth to manage automatic scale-down, see Viewing and Modifying the Global Properties .

» Try adding more memory to your server.

For working with large image files, 32 GB of physical RAM is a minimum recommended configuration on Windows systems.
