Pixel images (objects of class "im").
tol
Tolerance factor

  • Logical value: TRUE if the images are compatible, and FALSE if they are not.

Details

This function tests whether the pixel images A and B have compatible pixel dimensions. They are compatible if they have the same number of rows and columns, the same physical pixel dimensions, and occupy the same rectangle in the plane.
