liopaque - Makes an image more opaque or less opaque
LIBRARY CALL
int
liopaque(kobject src_obj, kobject dst_obj, double factor)
INPUT
src_obj - Input image
factor - Scaling factor
OUTPUT
dst_obj - Output image
RETURN VALUE
TRUE (1) on success, FALSE (0) otherwise
DESCRIPTION
This library routine allows making images more
opaque or less opaque. The color channels are
divided by the scaling factor while the alpha
channel is multiplied by the scaling factor.
Scaling factors greater than 1.0 increase
obscuration while factors less than 1.0 decrease
obscuration. If KPDS_DATA_RANGE is not defined
it will be defined.
ADDITIONAL INFORMATION
none
EXAMPLES
none
SIDE EFFECTS
No clipping is performed on the output image.
RESTRICTIONS
Scaling factor must be greater than 0.
MODIFICATION
