i want to extract text from an image. For example:
return: 12345678910
You should be able to do this via Tessnet2, which is an open source wrapper around the Tesseract engine.

I am using jsPDF to build my PDFs in my Quasar/Electron app. I have PDFs that I need to use as the base for the output, and I would love to be able to use that instead of building the whole PDF line by line. Does anyone know if this is possible?
This is an example of the PDF I need to use:
Score Sheet
I need to fill in the various details such as Call Name, Breed, etc. I'm not sure if it's possible to specify the exact position of the data while using the pre-made PDF.
Thanks for help!

There seem to be problems in the way PDF stores unicode devnagri text. Try this alternative route: convert your PDF to an image. Can use an online tool or downloaded, or if on linux use this command in terminal:
for f in *.pdf; do convert -density 200 "$f" "${f}_200dpi.jpg"; done
change the density from 200 to other as per need. Each page from your document should be converted into an image file. For a windows tool, try https://www.pdfill.com/pdf_tools_free.html
Then, go to http://www.i2ocr.com/free-online-hindi-ocr, upload the image and convert. That uses OCR (optical character recognition).
check the font in your PDF and try making it available to the word document.
I think you dont have perticular fonts which are used in PDF
In Adobe Reader -- -- File menu > Properties > Fonts tab gives you a list of all fonts used in the document.
I have a textbox in pdf which contains an image. Now I want to add hyperlink to that image programatically from code using itext. How can I achieve this?
Download the ExtractImages and MyImageRenderListener sample code. Rewrite it so that it doesn't extract the images, but use it to get the ImageRenderInfo and use its getMatrix() method. The Matrix gives you the coordinates and size of the images in your PDF.
Now use these coordinates to create a link annotation as is done in the TimetableAnnotations2 example.
Actually i am loading a pdf file in a view.
I have a search button when I enter the string I want it to search that string in entire pdf file and display it.
Can anyone tell me how to implement or Any sample code???
You can implement it using this sample code available here
I need to find an open source or linux based utility that allows me to set an x,y coordinate in a setup file. I would like to then sequentially open pdf's and look in the documents for first, last name and account number and save the file with a file name consisting of last name and file number.

The answers above are not Linux specific.
Most PDF documents do not need to be OCR'ed as the text is contained within the PDF. The hard part is extracting in. The Java version of iText (http://itextpdf.com/) is probably the best toolkit under Linux to extract the PDF text strings. Another option may be http://pdfbox.apache.org/
If the text you need to extract is actually an image then you will probably need to convert the whole PDF page to image format such as TIFF and pass that into an OCR engine such as Google Tesseract OCR.
