Specify the maximum file size of images (in kilobytes) for which the number of unique colors will be calculated when:
- One or more images are added to the Multimedia repository
-OR-
- Selected records in the Multimedia repository are updated using the Update Resource command.
Description
When an image is added to the Multimedia module, or the resource resolution of selected images is updated using the Update Resource command, the number of unique colors in an image is calculated and displayed in the Colors: (Image Attributes) field on the Resolutions tab.
In order to calculate the number of unique colors, each pixel in the image must be examined, and for very large images the time taken can be considerable (up to 2-3 minutes for an 8000 x 8000 pixel image).
The Maximum Size Registry entry allows a threshold to be set over which the number of colors is not calculated (the value is left empty) when an image is added to the Multimedia Repository or the Update Resource command is run on selected images (Multimedia>Update Resource>Selected Records).
Note: If the Multimedia>Update Resource>Current Record command is executed, the number of colors is calculated regardless of this Registry setting. This allows the value to be computed if required for an image that is over the threshold.
Usage
