Open source code for reading PDF

I wish to make an application with PDF code to read PDF files. I don’t wish to use an integrated PDF reader such as Adobe Reader, because I wish to move the pages from right to left, so is there any source code for a PDF reader that may operate in Android?

To slide pdf delegated best or vice-versa, you can utilize android pdf Viewer library. Go to the following site to view the guidelines and download link of source and demo codes. Ways to show pdf in android utilizing PDFViewer

I have really observed 2 method to accomplish this which is actually using UIWebView as well as using Quartz structure to attract the pdf pages. I’ve listened to slowness troubles using the UIWebView and also it is actually certainly not as pliable as utilizing the last approach.

Apple discussed “much better PDF assistance” in their Keynote, there’s no recognizable difference between iOS4 and brand new releases. May be that they enhanced PDF parsing inside, yet that’s sheer speculation on my side.

If you desire to get even more speed, even more functionalities, you possess to go in to the Quarta movement CGPDF * functions, as well as acquiring that right and simple is a real PITA. Specifically since there’s a lot points you carry out certainly not also recognize, e.g. that PDFs can easily possess rotation info, Crop/Media cartons and more. For fast scrolling, you additionally require some kind of UIScrollView that reuses it’s inner viewpoints to become rapid.

As a newbie iphone designer, 1) what topics should I learn initially (which frameworks/controls/library before going on as well as discovering the Quarta movement PDF support)? Is actually there everything new in iOS5/latest beta of Xcode pertaining to this?

As well as be really watchful along with CATiledLayer (which you require to permit quick zooming) – since that one operates multithreaded and also really loves crashing in your skin, when you carry out not end rendering appropriately. There are some enhancements in the iOS5 PDF rendering motor.

Utilizing UIWebView for pdfs isn’t really that excellent. Apple launched QuickLook in iOS4 for that, which is actually a bit a lot faster and also cleaner compared to the webview.

I have a CV in PDF format which is to be transformed to LaTeX code. Is there a way to ‘reverse engineer’ the PDF so that I can get the latex code?

You might get the plain text back however you can’t restore the original latex source.

You may be able to import PDF into a word processing program and export LaTeX from it (Either AbiWord of KOffice can do that, if I remember correctly), however the outcome will not be pretty. This will not get you the initial LaTeX, but a really poor approximation. I think recreating the CV from scratch in LaTeX will be simpler.

Much like you can immediately reverse engineer C code (though not very readable and with certain constraints) from an assembled exe you need to be able to reverse engineer the LaTeX code from a compiled PDF. There just do not seem to be any tools around that even try this. This would sure be a fascinating thing to implement.
