Find the Best Possible match

Asked by Chetan on 2021-09-30

we use findbest to find an image.
now on vm sometime it fails as the image match is less than 70% which is correct and expected due to slightly different resolution

however lets say if the image match is 50%. now we wish to the area. image where the match was 50% so that we can replace the current image with new one so that next time it would match 100%

any pointers would be appreciated

You have to write a function, that:
- captures the area of the match (result temp image file)
- overwrites the original image (file system move)
- resets the Image cache (Image.reset())

Thanks raiman for the response. can you please elaborate on point 1 - captures the area of the match (result temp image file)

below is the code we use

we use match=SearchRegion.findBest(name) // this gets us the match rate or None

now when match rateis <70( default) then None is returned. however logs show that can image matched with 58% match rate( see debug logs)

in this case we need to have the image location that had 58% match rate so that we can use that
how can we so that can you please help with pointers
