Name | Type | Description |
---|---|---|
hEntity | HIG_VECT_ENTITY | Geometry entity handle. |
lpColors | unsigned char* | Buffer for the local colors of the geometry. |
nStart | long | Index of the start color. |

Returns 0 if successful. Otherwise, returns the number of ImageGear errors that occurred during this function call.
This function does not process image pixels.
None
Using this function makes sense only if the argument bUseColors of IG_vect_geom_init() is set to VECT_TRUE.
The number of the color components is defined by nColorAlign argument of IG_vect_geom_init(). The color buffer must be long enough to receive (nEnd - nStart + 1) * nColorAlign bytes.
