|---|---|
AT_ERRCOUNT ACCUAPI IG_vect_geom_get_colors(
HIG_VECT_ENTITY hEntity,
unsigned char* lpColors,
long nStart,
long nEnd
);

Arguments:
| 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. |
| nEnd | long | Index of the end color. |
Return Value:
Returns 0 if successful. Otherwise, returns the number of ImageGear errors that occurred during this function call.
Supported Raster Image Formats:
This function does not process image pixels.
Sample:
None
Remarks:
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.
