Hello friends, using Sikulix 2.0.4 in Win7 - big trouble when running the script on a different system where the web app to automate is slightly scaled down. SCREEN.find() on the script patterns won't work anymore. So, I try at-runtime code to get the scaling factor for resizing of all the patterns to get find() to work, but SkuliX does not work as expected. Here the issue in 'manual' code:

pat = Pattern("1608112684558.png")    # a 737x50 search pattern
pat.similar(0.1)    # to avoid any FindFaileds

[On the scaled-down environment...]

pat.resize(1)
mat = SCREEN.find(pat)
print(mat.getScore())	# gives 0.603262484074, OK

pat.resize(0.99)
mat = SCREEN.find(pat)
print(mat.getScore())	# gives 0.753167867661, OK

pat.resize(0.98)
mat = SCREEN.find(pat)
print(mat.getScore())	# gives exception below!
"...org.sikuli.script.SikuliXception: image to search (737, 50) is larger than image to search in (729, 49)"
-> Does not resize the pattern anymore but uses the previous resized pattern as search region!?

pat.resize(0.97) or pat.resize(1.0)
mat = SCREEN.find(pat)
print(mat.getScore())	# gives exactly same exception as before!
"...org.sikuli.script.SikuliXception: image to search (737, 50) is larger than image to search in (729, 49)"
-> Very same error details with all different resize values!

***Now closing and restarting the SikuliX IDE ceteris paribus:***
pat.resize(0.98)
mat = SCREEN.find(pat)
print(mat.getScore())	# gives 0.878550231457, OK
-> Now it works, but why?

pat.resize(0.97) or pat.resize(1.0)
mat = SCREEN.find(pat)
print(mat.getScore())	# gives exception again
"...org.sikuli.script.SikuliXception: image to search (737, 50) is larger than image to search in (722, 49)"
-> Again, SikuliX bitching around with me, and needs to get restarted which would be, btw, acceptable with my wife, though...

Is this a (known?) bug in SikuliX, or is my understanding of .resize() bad? For sure I don't understand the exception message "image to search (w, h) is larger than image to search in (w, h)" - just makes no sense, also because the search region is SCREEN which is not in there. Please anyone help - I cannot deliver my solution if it cannot determine the needed pattern resizing factor based on a reference pattern for scale-changed applications across different screen resolutions///

Best!
Simon
