Hi! Some more findings: Using the "reproduce script": *) It does NOT crash, when OCR finds a text. *) It crashes also at counter 272 for different Regions/images, however: -) it does not crash (also not later) when I select a Region with "easy" background (not many patterns) -) taking a much bigger region results in no difference -) finding a word in the meantime makes no difference, the script always crashes at 272 -) OCR.reset() in the meantime makes no difference, still crash at 272 -) replace Reg.text() to OCR.readText() - same, still crash at 272 -) OCR.readLine(), readWord, readChar are also crashing (different count (=128)), even tough they find characters in any pattern. -) Doing OCR alternatively on word and on non-word patterns let it crash earlier (at 172) -) Doing OCR on words only does not crash within 1000 runs -) OEM=0, PSM=8 also crash -) OEM=0, PSM=2 also crash
I hope I found some useful information. I was not able to find a workaround (other than avoiding OCR on non text).

I am using Sikulix 2.0.4 on Windows 10 64bit, JAVA 11, 2 large sized Monitors (3440x1440 + 2560x1440 as one display, NVIDIA). Sikulix crashes (meaning: it does not process anymore, does not write logfiles, ALT-SHIFT-C does not work, JAVA needs to be killed in taskmanager to restart sikulix) within following function in about 1 of 10 cases. only when it tries to OCR read text in an area where there is no text: def text_shrink(Reg): # continously decrease region until OCR gets a match texts=False Reg=Reg.grow(30,30,0,0) while (texts==False or len(texts)<=2) and Reg.getW()>20: Reg=Reg.grow(-30,-30,0,0) texts=ExtractAlphanumeric_all(Reg.text()).strip() #crash here on OCR return texts The images for this particular run where the crash happend is attached.
