This is similar to the objective I've asked about on another topic (How to save the DIFFERENCES between two images ?): viewtopic.php?f=1&t=15584
Except this time that the two images are of different size.
Here are the details...
I have two images:
image1.png -- this is the background image
link to image: https://docs.google.com/leaf?id=0B-jgOG ... ZTc4&hl=en
imge2s.png -- this is the background image with some stuff added to it. However, this image is only a sub-section of image1.png.
this image is smaller than image1.png.
link to image: https://docs.google.com/leaf?id=0B-jgOG ... NmRi&hl=en
the ultimate end goal is still the same as what I've asked in the other topic:
save the differences between the two images.
In the end, I should see the same "plants" as the diff as in the other topic.
Here is the expected output: https://docs.google.com/leaf?id=0B-jgOG ... MDU2&hl=en
It seems to me that in order to accomplish that, I have to first tell IM to local the image sub-image first and then only do a diff on the matching sub-image section.
Question is, is it possible to do that? If so, how?
