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).
