);

| Name | Type | Description |
|---|---|---|
| hIGear | HIGEAR | Image to process. |
| dblThreshold | AT_DOUBLE | A value in the range 0.5..2 that specifies a part of the red component in the pixel color. |
| dblBrightness | AT_DOUBLE | Scaling factor for brightness of the pixel after processing. The range is -1...1. |
| lpRect | LPAT_RECT | Rectangular area to apply the effect to, or NULL for whole image. |
Returns the number of ImageGear errors that occurred during this function call.
RGB – 3…48 bpp;
RGBA, RGBPA – 4..64 bpp;
RGBEx, RGBAEx, RGBPAEx – 1…16 bpc;
CMYK – 32 bpp.
The algorithm can be applied to the entire image, to a rectangular ROI defined by the lpRect parameter, or to a non-rectangular ROI set using the IG_IP_NR_ROI_mask_associate function. The function IG_IP_detect_redeye_area can assist in defining a non-rectanular ROI suitable for use with this function.
