Tesseract approach is to not re-compress/change image type of input image in pdf creation. So you need to use other tools for creating smaller pdf. Zdenko ut 13. 11. 2018 o 7:49 napísal(a): > I've not used Tesseract in many years until today. I'm very impressed > with what I see now. > > I ne

If you install tesseract, all needed headers will be installed to specified/system location. Referring headers directly to ccstruct etc. is simple bad design of you application. Zdenko so 24. 11. 2018 o 14:18 'Yuliana Zigangirova' via tesseract-ocr < tesseract-ocr@googlegroups.com> napísal(a):

ImproveQuality suggests much more than adding a border ;-) Actually it suggest Scanning border Removal (cropping - I did it manually, just do demonstrate it helps ;-) ) and noise removal, binarization... Also it suggest several tools. So all your answers to your questions are in wiki page you refer

Re: [tesseract-ocr] What upper-level header files are really needed when using Tesseract API and what can be left out?

Your explanation is quite strange for me: you want to build application that use tesseract in environment where you can not build/install tesseract??? Anyway it your problem: installed header your can find here: https://github.com/tesseract-ocr/tesseract/blob/267b79982d64e48d11eaa99ee2618106662a9
