I was trying to extract text from an image using pytessaract, but it skipped a portion of image. But similar text was extracted from the same image. And when I made an image by cropping the skipped portion and extracted the text , all the text was extracted. Can anyone help me to figure out what is the reason. Thank you all in advance.

I know Ghostscript can translate pdf into png.
Can you tell which lines in the source code to comment out so that blocks with text are simply skipped (ignored) when converting pdf to png.
Don't modify the source. Instead use -dFILTERTEXT which will drop text rather than rendering it. See here

Can anyone suggest me how to convert a scanned image into a searchable image or a scanned pdf to a searchable pdf ?
I have been stuck in this situation since quite a while now.
i have tried pdfocr application in ubuntu but no success.
Tesseract version 3.03 supports creation of searchable PDF from image. For PDF, you can use GhostScript to convert it to image before sending it to Tesseract.

Currently, there is no right way of doing this on Ubuntu. All OCR engines output plain text and there is no way to add that text as a hidden layer on PDF over the image text.
Option 1: Use gscan2pdf which will make you a searchable PDF, but the OCRed text is placed in the top-left corner of the page, is invisible and much too small.
Option 2: Use PDF X-Change Viewer which has an option to OCR and works correctly by adding a text layer over the scanned image which is in concordance with it. You'll have to run it in wine, because it is a Windows application.
I'm doing a document scanning project that involves inserting a scanned image into an existing PDF template page that contains form fields. I've used ImageMagick to take process the scan, and then append a raster image of the form template to the bottom, and convert that image into a PDF. However, forms and checkbox fields have to be added manually to the resulting PDF. Below is a sample of my ImageMagick command.
convert inputScan.jpg -resize 975x420 FormTemplate.png -append CombinedFile.pdf
Ideally, I would run a command that would take the JPG scan and the PDF template file containing fields, and output a PDF file with the scan at the top of a page and the field-containing template text below it. The closest thing I could find to a solution was here, but PHP can't be used on the computer in question.
Any help or suggestions are greatly appreciated!
