|
|
*
|
|
* This tool makes it possible to gather information about the
|
|
* intensity histogram of a drawable. A channel to examine is first
|
|
* specified. This can be either value, red, green, or blue, depending
|
|
* on whether the drawable is of type color or grayscale. The drawable
|
|
* may not be indexed. Second, a range of intensities are specified.
|
|
* The gimp_histogram() function returns statistics based on the pixels
|
|
* in the drawable that fall under this range of values. Mean, standard
|
|
* deviation, median, number of pixels, and percentile are all
|
|
* returned. Additionally, the total count of pixels in the image is
|
|
* returned. Counts of pixels are weighted by any associated alpha
|
|
* values and by the current selection mask. That is, pixels that lie
|
|
* outside an active selection mask will not be counted. Similarly,
|
|
* pixels with transparent alpha values will not be counted.
|
|
*
|
|
* Returns: TRUE on success.
