Clamp
Brief Description
Restrict the pixel values in the image to a range. If Minimum is enabled, the values below the minimum are set to the Minimum. If Minimum Value is enabled, the minimum values are set to this value instead of Minimum. This is useful for example to make everything below 0 become 1.
If Maximum is enabled, the values above the maximum are set to the Maximum. If Maximum Value is enabled, the maximum values are set to this value instead of Maximum. This is useful for example to make everything above 1 become 0.
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 |
Minimum Enabled / minimum_enabled | Boolean | On | Enable low clamp |
Minimum / minimum | Color | 0, 0, 0, 0 | The low clamp value |
Maximum Enabled / maximum_enabled | Boolean | On | Enable high clamp |
Maximum / maximum | Color | 1, 1, 1, 1 | The high clamp value |
Enable Min Value / min_clamp_value_enabled | Boolean | Off | When checked, all values below minimum are clamped to the Min Value value. When unchecked, all values below minimum are clamped to the minimum value. |
Min Value / min_clamp_value | Color | 0, 0, 0, 0 | The value to which low illegal values are clamped when Enable Min Value is checked. This sets the clamped areas to a custom color, allowing you to visualize the clamped range or create graphical effects. |
Enable Max Value / max_clamp_value_enabled | Boolean | Off | When checked, all values above maximum are clamped to the Max Value value. When unchecked, all values above maximum are clamped to the maximum value. |
Max Value / max_clamp_value | Color | 1, 1, 1, 1 | The value to which high illegal values are clamped when Enable Max Value is checked. This sets the clamped areas to a custom color, allowing you to visualize the clamped range or create graphical effects. |
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 |
