Hi! I am new with Sikuli and Tesseract OCR; I like to recognise text using
Sikuli OCR and Jython as
'strLast = OCR.readWord(regLastFallenNumber)', or
'strLast = regLastFallenNumber.text()'
I am running Sikuli 2.0.4-2020-03-14_08:01 / WINDOWS 6.1 (=Win7) 64bit / java
version "1.8.0_251"; Sikuli automation works.
It fails with this for the OCR class call:
"...
) raised: Traceback (most recent call last):
File "<string>", line 14, in <module>

java.lang.NoClassDefFoundError: java.lang.NoClassDefFoundError: Could not
initialize class net.sourceforge.tess4j.Tesseract1"
So, I researched int internet and found about Tesseract that it "Windows: Works
out of the box". So, why then the above message?
By the way, here the Jython I was using in the Sikuli IDE - also not sure that
I am not mixing up concepts there...
# OCR configuration
import org.sikuli.script.TextRecognizer as STR # switch on the OCR
feature
OCR.reset()
optMySet = OCR.Options()
optMySet.oem(3)
optMySet.psm(8)
optMySet.asWord()
optMySet.language("eng")
#optMySet.smallFont()
optMySet.variable("user_defined_dpi", "112")
STR.reset()
#print optMySet
Settings.OcrTextRead = True
regLastFallenNumber = Region(425,292,48,21)
regLastFallenNumber.highlight(1)
strLast = OCR.readWord(regLastFallenNumber)
#strLast = regLastFallenNumber.text()
print strLast
Thanks a lot for your help :)
