Threshold
Brief Description
Applies a threshold to the image: all pixels with smaller values to the threshold are converted to 0 and all values above the threshold to 1.
Controls
| Parameter / Script Name | Type | Default | Function |
|---|---|---|---|
Enabled / enabled | Boolean | On | |
Red / process_red | Boolean | On | Enable the red channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0 |
Green / process_green | Boolean | On | Enable the green channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0 |
Blue / process_blue | Boolean | On | Enable the blue channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0 |
Alpha / process_alpha | Boolean | On | Enable the alpha channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0 |
Mode / threshold_mode | Choice | Luminance | Threshold mode - Luminance: Convert to a luminance image and apply threshold - Mask: Generate alpha mask from luminance threshold - RGBA: Separate RGBA threshold |
Threshold / threshold_value | Color | 0.15, 0.15, 0.15, 0.15 | Sets the threshold value. All channel values below these are converted to zero, and all values above are converted to one. |
Feather / threshold_feather | Float 4D | 0.01, 0.01, 0.01, 0.01 | Sets the threshold softness. Higher values result in softer transitions between levels. |
Unpremult / predivide | Choice | If Needed | - If Needed: The image RGB channels are divided by the alpha channel before applying the effect if the image is marked as alpha-premultiplied - Never: The image RGB channels are never divided by the alpha channel before applying the effect, even if the image is marked as alpha-premultiplied |
Mask / mask | Image | - | |
Mix / mix_with_source | Float | 1 | Dissolves between the original image at 0 and the image with the effect applied at 1 |
