Description étendue
Generates the histogram of a selected image. When the user right clicks on an image, the option "Histogram Viewer" is shown in the context menu. If the user selects this option a new window is opened which shows the histogram of the image.
Currently this histogram is generated based on the sum of all 3 RGB color channels. An individual histogram for each of the 3 color channels is planned for the future as well the output of statistical values like min, max, mean, median.
Please note that it may take a while to generate the histograms for large images. So when you get the "Warning: unresponsive Script" please click continue and be patient. This warning can occur several times on really large images (>5 mega pixel). For next major version a "rough histogram" is planned which will generate a quick but not as accurate version and only if specifically asked for a histogram based on the original sized image.
