Methods have access to the instance variables of the object and can call
other methods of the object using the "self" variable, so watch out for
them. In the _combineImages example, there was only the self.color
variable, so how about something like:

function mg_create_anaglyph, leftImage, rightImage, color=color
compile_opt strictarr

; define combined_image to the correct size
combinedImage = leftImage * 0B
dims = size(leftImage, /dimensions)

if (keyword_set(color)) then begin
combinedImage[0, *, *] = leftImage[0, *, *]
combinedImage[1, *, *] = rightImage[1, *, *]
combinedImage[2, *, *] = rightImage[2, *, *]
endif else begin
_leftImage = byte(total(fix(leftImage), 1) / 3)
_rightRight = byte(total(fix(rightImage), 1) / 3)

combinedImage[0, 0, 0] = Reform(_leftImage, 1, dims[1], dims[2])
combinedImage[1, 0, 0] = Reform(_rightRight, 1, dims[1], dims[2])
combinedImage[2, 0, 0] = Reform(_rightRight, 1, dims[1], dims[2])
endelse

return, combinedImage
end
