Threshold
Limit the colour in an image.
Threshold
Method #
This node limits the range of colour values in the image based on the luminance of each pixel. Useful for removing areas of an image which fall below a certain brightness level.
Parameters
These properties control the core behaviours of the node.
Parameter Details
Active Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Blend Amount Changes the opacity of the new effect over the original image.
Blend Mode (RGB) Change how the generated effect blends with the parent image RGB.
Threshold Change the luminance threshold for the effect to apply.
Falloff Range Control the falloff of the threshold edge.
Falloff Power Control the strength of the falloff.
Mode Change how the threshold functions.
- Above : Anything below the threshold is omitted.
- Below : Anything above the threshold is omitted.
- Band : Anything outside the middle values are omitted, within the range specified by the threshold.
Output Mode Change how the cut image outputs.
- Colour : Colour is output along with the image.
- Mask : A mask is generated based on the regions inside the threshold.
