CImCombine:RgbMerge
The RgbMerge method creates a new RGB color image by merging R, G, and B channel images from the first 3 members of a CImageSet.
|
CImage = CImageSet:RgbMerge( CImageSet ) |
CImageSet contains the R, G, and B channel images
(the order R, G, B is important).
On success,
this method returns the merged color image as a new CImage.
On failure,
this method returns nil.
Suppose that 3 CImage objects exist with names R,G, and B and have the same dimensions (the DimEq method can be used to test this before merging). The following script fragment merges these images into an RGB image:
|
S = CImageSet:new() |
-- create an image set to hold the images |
|
S:Append(R) |
-- add channel images to the image set |
|
S:Append(G) |
|
|
S:Append(B) |
|
|
C = CImCombine:new() |
-- create a CImCombine object |
|
I = C:RgbMerge( S ) |
-- merge the channels and return a new CImage |
|
S:delete() |
-- delete S if no longer needed |
|
C:delete() |
-- delete C if no longer needed |
