        HIGEAR hIGear,
        LPDWORD lpdwAngle
);

Arguments:

Return Value:

Returns the number of ImageGear errors that occurred during the function call.

Supported Raster Image Formats:

All pixel formats supported by ImageGear for C and C++.

Example:

HIGEAR hIGear;   /* HIGEAR handle of Image  */
DWORD dwAngle;   /* Rotation angle    */
AT_ERRCOUNT nErrCount; /* Tally of IG errors on stack  */
nErrCount = ART_rotation_angle_get (hIGear,&dwAngle);

Remarks:

Valid values are 0, 90, 180, 270.
