Histogram render

Input Grayscale PRIMARY

The image for which the histogram should be drawn.

Output Grayscale

The histogram visualization computed out of the input image.

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.
