The AdjustHLS method sets nHue, Brightness, and nSaturation components for an image page or selected rectangular area using the HLS color model.
Syntax
HRESULT AdjustHLS([in] double nHue,
[in] double nLightness,
[in] double nSaturation,
[in, defaultvalue(NULL)] RECT* stRect);
Parameters
- nHue
- [in] Specifies the Hue level to be applied to the page or its part. The range of the value is from -1.0 to +1.0.
- nLightness
- [in] Specifies the Brightness level to be applied to the page or its part. The range of the value is from -1.0 to +1.0.
- nSaturation
- [in] Specifies the Saturation level to be applied to the page or its part. The range of the value is from -180 to +180.
- stRect
- [in, defaultvalue(NULL)] Pointer to RECT structure which defines the rectangular area where the function should be applied. If this parameter is NULL, the entire page will be processed.
Note:
Please note that processing of part of the page is not supported for some internal formats. For example, it is not supported for indexed images, because each pixel in such images does not contain the color, but an index into a color table (or palette) which is common for the entire page.Return Value
Returns S_OK if operation was successful or error code in other cases.
