Hue Saturation Changing Filter

Filter

RIF_IMAGE_FILTER_HUE_SATURATION

Description

Hue-saturation tool. Adjusts hue, saturation and brightness.

Parameters

Parameter	Type	Input/Output	Description
saturation	float	input	Saturation value. Saturation is the “colorfulness of an area judged in proportion to its brightness” which in effect is the perceived freedom from whitishness of the light coming from the area. Default value is 1.
hue	float	input	The degree to which a stimulus can be described as similar to or different from stimuli that are described as red, green, blue, and yellow. Value range is [-180, 180], default value is 0.
value	float	input	Brightness multiplier. Default value is 1.

Usage Example

rif_image_filter filter = nullptr;
rifContextCreateImageFilter(context, RIF_IMAGE_FILTER_HUE_SATURATION, &filter);
rifImageFilterSetParameter1f(filter, "saturation", 1.0f);
rifImageFilterSetParameter1f(filter, "hue", 90.0f);
rifCommandQueueAttachImageFilter(queue, filter, inputImage, outputImage);
rifContextExecuteCommandQueue(context, queue, nullptr, nullptr, nullptr);
