Method Image.Image()->`==()

Method `==

int res = Image.Image() == operand
int res = Image.Image() == color
int res = Image.Image() == value
int res = Image.Image() < operand
int res = Image.Image() < color
int res = Image.Image() < value
int res = Image.Image() > operand
int res = Image.Image() > color
int res = Image.Image() > value

Description

Compares an image with another image or a color.

Comparision is strict and on pixel-by-pixel basis. (Means if not all pixel r,g,b values are correct compared with the corresponding pixel values, 0 is returned.)

Parameter operand

the other image to compare with; the images must have the same size.

Parameter color

an array in format ({r,g,b}), this is equal to using an uniform-colored image.

Parameter value

equal to ({value,value,value}).

Returns

true (1) or false (0).

Note

`< or `> on empty ("no image") image objects or images with different size will result in an error. `== is always true on two empty image objects and always false if one and only one of the image objects is empty or the images differs in size.

a>=b and a<=b between objects is equal to !(a<b) and !(a>b), which may not be what you want (since both < and > can return false, comparing the same images).
