Detailed Description

Classes for in-memory storage and simple manipulation of whole images, which uses ImageInput and ImageOutput underneath for the file access.

Function Documentation

OIIO_API ROI get_roi

(

const ImageSpec &

spec

)

Return pixel data window for this ImageSpec as a ROI.

OIIO_API ROI get_roi_full

(

const ImageSpec &

spec

)

Return full/display window for this ImageSpec as a ROI.

OIIO_API ROI roi_intersection	(	const ROI &	A,
		const ROI &	B
	)

Intersection of two regions.

OIIO_API ROI roi_union	(	const ROI &	A,
		const ROI &	B
	)

Union of two regions, the smallest region containing both.

OIIO_API void set_roi	(	ImageSpec &	spec,
		const ROI &	newroi
	)

Set pixel data window for this ImageSpec to a ROI. Does NOT change the channels of the spec, regardless of newroi.

OIIO_API void set_roi_full	(	ImageSpec &	spec,
		const ROI &	newroi
	)

Set full/display window for this ImageSpec to a ROI. Does NOT change the channels of the spec, regardless of newroi.
