Anisotropic Kuwahara Grayscale icon

In: Filters > Adjustments

Description

Draws the histogram for a grayscale image.


Input connectors

Input

Grayscale

PRIMARY

The image for which the histogram should be drawn.


Output connectors

Output

Grayscale

The histogram visualization computed out of the input image.


Parameters

Histogram resolution

Integer

The width of the histogram. A higher value allows for a finer value distribution.

 

Available resolutions are, in pixels:
256, 512, 1024, 2048, 4096

Automatic scale

Boolean

When 'True', remaps the histogram to use the full height of the image.

 

When 'False', each column uses as many pixels in height as there are occurrences of a value in the input image.

Scale

Float

Scales the histogram vertically, where a value of 1 is the full height of the histogram.

Sampling

Integer

The method of filtering the histogram image, which impacts the result when the histogram resolution and render resolution mismatch:

  • Bilinear: applies bilinear filtering to the histogram, resulting in interpolated points
  • Nearest: samples the nearest pixel with no filtering, resulting in flat steps

Flip Y axis

Boolean

When 'True', mirrors the histogram vertically.
