xsh_detmon_load_frameset_window()

cpl_imagelist * xsh_detmon_load_frameset_window	(	const cpl_frameset *	fset,
		cpl_type	type,
		cpl_size	pnum,
		cpl_size	xtnum,
		cpl_size	llx,
		cpl_size	lly,
		cpl_size	urx,
		cpl_size	ury,
		cpl_size	nx,
		cpl_size	ny
	)

load data in frameset into an imagelist

Parameters

fset	frameset to load from
type	type to convert data to
pnum	plane number in cube to load (0 for first)
xtnum	extension in file to load (0 for first, -1 for all)
llx	lower left x
lly	lower left y
urx	upper right x
ury	upper right y
nx	output image size x
ny	output image size y

Returns

imagelist of loaded images padded to nx/ny

Note

pads images with zeros to output image size unlike cpl_imagelist_frameset_load no support for loading multiple planes
