Search specific region for image

[Funnymanphil]

Hi, I'm trying to implement a way in RF with Sikuli to check whether a specific region on screen contains an image that I have captured before. I was wondering if it's possible to add this function, or if it's already possible and i haven't figured it out. I know that it's possible with sikuli in java with the reg.find("targetPattern) command, but I'm unsure how it would work in RobotFramework, and I haven't been able to see any other topics discussing this issue so far.
Thanks in advance for any help.

@RobotKeyword ("Region Should Contain"
            + ".\n Scans a region of the screen with given coordinates and checks whether the region contains the targeted image"
            + ".\n @targetImage: expected image in region"
            + ".\n| ${coordinates} | Create List | x | y | w | h |")
    @ArgumentNames({"coordinates", "targetImage"})
    public void RegionShouldContain(ArrayList<Object> coordinates, String targetImage) throws ScreenOperationException {
        int x = Integer.parseInt(coordinates.get(0).toString());
        int y = Integer.parseInt(coordinates.get(1).toString());
        int w = Integer.parseInt(coordinates.get(2).toString());
        int h = Integer.parseInt(coordinates.get(3).toString());
        Region region = new Region(x, y, w, h);
        Match match = region.find(getPattern(targetImage));  
        if (match != null)  {
            capture(region);
        } else {
            capture(region);
            throw new ScreenOperationException("Screen region does not contain "+targetImage);
        }
    }

This is what I had in mind for the ScreenKeywords.java Library, and then adapting the keywords.py file as well
