[FPubD] Searchable PDFs

[sk33wiff]

Hi,

I was wondering if there is anyway of adding search support for the generated PDFs.

This one is good example:

https://issuu.com/guani/docs/designpatternscard

If downloaded through issuu.com, the PDF has searching support. But not when it's downloaded by the tool.

Congrats on the project!
Cheers

Hi,
Thank you for using my tool!

I appreciate your suggest. In this case mentioned by you, the publication's author submitted an original PDF file with text (or OCR'zed) capability, created, for example, in Adobe Acrobat Pro. And, the author authorized the publication for normal download into issuu.com.

My difficult is to find an open source pure JavaScript OCR library, because PDF generation library used no contains OCR capability. My tool generate a PDF file by source images (JPG), available to any person, from issuu.com, for all publications hosted in this site.

If you know any open source pure JavaScript OCR library (that works over static JPG images), please help me.

For this moment, to convert a 'non searcheable' PDF to a 'searcheable', use the OCR tool by Adobe Acrobat Pro software.

I see, thanks for the explanation.
In regards to the libs, I just recently came across these ones:

• https://github.com/naptha/tesseract.js
• https://github.com/antimatter15/ocrad.js

I've created a codepen as a Tesseract demo: http://codepen.io/anon/pen/pNmEMm
It currently uses data uri for the image due to cross-domain limitations

Ocrad demo: https://github.com/kdzwinel/JS-OCR-demo

Not sure how realist is to use them,
Cheers

@marcelopm e @robsonsmartins
monitorei o app para iPhone e ele busca a url https://publication.issuu.com/guani/designpatternscard/ios_1.json
com isso fica fácil pegar os PDFs em alta qualidade

Thanks, @marcelocecin
This URL/pattern contains searchable PDFs of all pages of a publication.
I'm looking for a free/open source JavaScript library to merge many PDF files in one.

This might help with the merging:
