Same image with different colors are the same for Sikuli

Asked by Deses

Hello and congratulations for this excellent piece of work.

Screen A: http://dl.dropbox.com/u/2240774/A.png
Screen B: http://dl.dropbox.com/u/2240774/B.png

Well, I have a problem trying to automate a game, when it comes to tell if screenshot A exists, no matter how far I set the slider to tune the similarity, it always thinks that it's screenshot B.

I don't have to click on the image, only find if it exists, but as far as I know, Sikuli doesn't discriminate between colors. Ohter users had similar problems.

There is something I can do, or do you have any tip for me to fix that?

Thanks!!

If interested, I have the full screenshots:

Tested on my Mac Lion with your images.

I confirm, that both images in both cases give the same score. So the normal features of Sikuli will not help you.

This is the easiest workaround:

from java.awt import Robot

imgA = "A.png"

m = find(imgA)
cp = m.getTopLeft().offset(5,5) # select a pixel, that has the background color
r = Robot()
c = r.getPixelColor(cp.x, cp.y) # get the color object
crgb = ( c.getRed(), c.getGreen(), c.getBlue() ) # decode to RGB values
print crgb

you will get a different color value in both cases, which makes it possible to decide with one is present.

Oh my, that was really fast. (I just woke up xD)

I've tryed your code and at first it couldn't found the Robot method, but then I realized that I didn't imported the class... I'm still asleep. Hehe

Well, this solves my question.

Thanks a lot! You are awesome. :D

Hmm, how do I compare between crgb (or c) and a fixed variable?

gris = (176, 160, 125)

if crgb == gris:
    do things

Is that correct?
