ARITHMETIC Monash Image Library ARITHMETIC These functions are for applying scalar operations to each pixel of an image. In general they ignore overflow and underflow results. Last Modified: 20 November 1992
| iaddscalar | increment all pixels by n |
| idivscalar | divide all pixels by n |
| ilshift | multiply all pixels by two |
| imask | Applies a scalar values to each pixel in the image using the given operator (= and or xor mean min max sub over lshift rshift rand diff) |
| imulscalar | multiply all pixels by n. Does not check for overflow. |
| ipasteop | Applies bg image at row, col on fg image using the given operator (= and or xor mean min max sub over lshift rshift rand diff). ie out = fg op bg. |
| irshift | divide all pixels by two |
| izero | zero all pixels |
