How to use the code?

1.Setup your python env according to the requirements.txt
2.Create a folder named "models", download and unzip models_texify.zip to the folder "models" from release page v1.7
3.Create a folder named "texmml", download and unzip texmml.zip to the folder "texmml" from release page v1.2
4.Just run the ocr_gui.py
I've tried my best to simplify the code and preject,so it's easy to modify the GUI and intergrate other OCR model to this.

Potential issues

1、It will consume much time if you snip a very large image.
2、Some format errors in MathML because it's tranformed from latex.I've tried to solve most of them.I suggest copying latex to mathtype directly
3、Sometimes, there can be formatting issues with curly braces.
4、Some letters or symbols cannot be recognized because not or rarely in the token vocabulary or training set.
5、If you paste a very long formula to mathtype, it will report a error.So please avoid that.

If you find any other issues，contact me.I'll keep updating this if necessary.

Fequently Asked Questions

1、Support for Mac
I'm trying to find a Mac to develop and test first but there is even no a Mac I can borrow.So I'll try a cloud Mac then.
2、Self-defined Shortcut for Snipping
I have set Alt+Q in the v1.4 for snipping which will satify most people.And probably I wont't add a self-define function, because it'll introduce a config file which will make FMatPix.exe -> FMatPix.exe + xxx.xml. I mean there'll be an additional file.
Forgive my OCD please.
3、Support for double monitors
From v1.5,FMatPix has started supporting double monitors.
