gimp_channel_combine_masks

Input:

CHANNEL	channel1	The channel1
CHANNEL	channel2	The channel2
INT32	operation	The selection operation: { GIMP_CHANNEL_OP_ADD (0), GIMP_CHANNEL_OP_SUBTRACT (1), GIMP_CHANNEL_OP_REPLACE (2), GIMP_CHANNEL_OP_INTERSECT (3) }
INT32	offx	x offset between upper left corner of channels: (second - first)
INT32	offy	y offset between upper left corner of channels: (second - first)

Returns: nothing
This procedure combines two channel masks. The result is stored in the first channel.
Spencer Kimball & Peter Mattis; 1995-1996

gimp_channel_get_show_masked

Input:

CHANNEL

channel

The channel

Returns:

INT32

show_masked

The channel composite method

This procedure returns the specified channel's composite method. If it is non-zero, then the channel is composited with the image so that masked regions are shown. Otherwise, selected regions are shown.
Spencer Kimball & Peter Mattis; 1995-1996

gimp_channel_set_show_masked

Input:

CHANNEL	channel	The channel
INT32	show_masked	The new channel composite method

Returns: nothing
This procedure sets the specified channel's composite method. If it is non-zero, then the channel is composited with the image so that masked regions are shown. Otherwise, selected regions are shown.
Spencer Kimball & Peter Mattis; 1995-1996

plug_in_unsharp_mask

Input:

INT32	run_mode	Interactive, non-interactive
IMAGE	image	(unused)
DRAWABLE	drawable	Drawable to draw on
SUCCESS	radius	Radius of gaussian blur (in pixels > 1.0)
SUCCESS	amount	Strength of effect
SUCCESS	threshold	Threshold

Returns: nothing
The unsharp mask is a sharpening filter that works by comparing using the difference of the image and a blurred version of the image. It is commonly used on photographic images, and is provides a much more pleasing result than the standard sharpen filter.
