Arguments:
| hIGearOrig | HIGEAR handle of the original image to be separated. |
| lphIGear1 | Far pointer to an object of type HIGEAR to receive the handle of the separated channel 1 image. |
| lphIGear2 | Far pointer to receive handle of channel 2 image. |
| lphIGear3 | Far pointer to receive handle of channel 3 image. |
| lphIGear4 | Far pointer to receive handle of channel 4 image. |
| nColorSpace | A constant such as IG_COLOR_SPACE_RGB or IG_COLOR_SPACE_CMYK describing how the individual channels are to be separated or extracted. |
Return Value:
Returns the number of ImageGear errors that occurred during this function call.

|---|---|
HIGEAR hIGear, /* HIGEAR handle of input image */ hIGearRed, /* Handle of Red output image, */ hIGearGreen, hIGearBlue, /* Green, Blue output images */ hIGearNULL; /* (Not used when IG_COLOR_SPACE_RGB) */ AT_ERRCOUNT nErrcount; /* Returned count of errors */ nErrcount = IG_IP_color_separate ( hIGear, &hIGearRed, &hIGearGreen, &hIGearBlue, &hIGearNull, IG_COLOR_SPACE_RGB ); |

Remarks:
This function is the reverse of IG_IP_color_combine_ex(). See the description of that function. Each of the output images created by this function (lphIGear1, etc.) will be grayscale. That is, each will have a grayscale palette. The pixel values will be those obtained from the input image.
