RaiMan proposed the following answer:
First of all: please use 2.0.4, so I can help you better.
Second: please send me a sample of such a number image to my mail
sikulix---at---outlook---dot--com (original as shown on screen)
When using the OCR features of SikuliX the image is optimised according
to the recommendations, before giving it down to Tesseract.
I have to admit, that you are talking about an edge case, where the
conversion to grayscale as part of the optimisation, is not sufficient
and black/white is needed.
I will add such an option to version 2.0.5.
With the Mat-conversion I cannot help you in the moment, since the respective
API, that is used inside of SikuliX, is not accessible from the outside world
(non-public).
To support such experiments I will make the features image-to-Mat and
Mat-to-image available in 2.0.5.
You might look at the code and rewrite it in a Jython script, since you
can use Java in this environment.
--- Image-to-Mat
org.sikuli.script.Finder.Finder2.makeMat(BufferedImage bImg, boolean asBGR)
--- Mat-to-image (as .png)
org.sikuli.script.Finder.Finder2.getBufferedImage(Mat mat)
