Arguments:
| Name | Type | Description |
| hIGear | HIGEAR | Image to which to apply the effect. |
| nDistance | AT_INT | Distance to the cylinder axes, in pixels. |
| nRadius | AT_INT | Cylinder radius, in pixels. |
| nHeight | AT_INT | Height of the cylinder segment, in pixels. Height can be changed from (-radius) to (radius). |
| bHorizontal | AT_BOOL | If TRUE, cylinder is horizontal. |
| bInterpolate | AT_BOOL | If TRUE, interpolation is used during processing. |
| hbkColor | HIGPIXEL | Background color. It should have the same color space and channel depths as the image to which the effect is applied. |
| lpRect | LPAT_RECT | Rectangle area to which to apply the effect, or NULL for whole image. |
Return Value:
Returns the number of ImageGear errors that occurred during this function call.
