I'm trying to display a .pdf file on a browserfield but somehow it's not opening in my app however it works fine with .txt files.
I'm reading .pdf file from local storage and using
browser_field.displayContent(fileinbytes, "application/pdf", "");
but it's displaying a player like image on the screen and not actual result.
If anyone has any idea about the same, i'm all ears.
As far as I can tell this isn't possible (browserfield doesn't even fully support javascript).
This post suggests that you can view it via Google, which wouldn't be from local storage.
(Un)luckily blackberry is very similar to Java ME, so you can often use those libraries as is. Apparently JPedal can render pdf files for J2ME, and might be worth a look.
Other than that, I don't think you'll have much hope. Good luck

Quick question, that I haven't found a solid answer yet.
Is it possible to generate a PDF in iOS that includes layers, which can then be removed/separated in Photoshop?
What I'm trying to achieve is take a picture with the camera of the phone, then place text over it, submit it as pdf to a customer and then have the customer read the text and remove it.
I can do everything except the layering of the pdf and I have found some hints that this isn't possible to do with the standard iOS library, but I wanted to know if anyone has come across this before.
Thank you.
The standard iOS API for creating PDF files cannot create layers (optional content) in a PDF page.
This library IFXPDFFactory seems to be able to generate PDF files with layers.
PoDoFo and libHaru can also be used to generate PDF files on iOS but I do not know if they support layers.
Need help on rendering PDF using CGPDFContext. I am currently using UIWebView to display PDF but would like to perform much more operation rather than just reading like Highlight Text, Search PDF, Annotate PDF. Not looking for using any Framework or library.
Any help will be beneficial. For a start, code on how to render PDF using CGPDF and displaying it instead of using UIWebView.
PDF annotations are a rabbit hole. I've been working on them since 2010. The spec is thousands of pages. It's easy to get started but it takes forever to get right with all the PDFs and variations out there. Even a simple feature like bookmarks are harder than you would think.
To date there's no open source framework that implements PDF annotations. The above linked one can be a good starting point. If you don't have months/years to build something on your own, there are a few commercial options available - like PSPDFKit, available for iOS, Android and Web, which I am building.
We have a guide article listing the most important PDF spec documents.
Searching is another tricky topic. It's quite hard to convert the PDF text data to unicode. The Adobe CIDFont spec is a good starting point.
You shoud try VFReader, it is an open source project for rendering PDF files on iOS. It can be a good starting point.
In my application, i have uploaded PPT,PPTX files using paperclip gem. I have url like this
" Presentation.last.avatar.url" = "/system/presentations/avatars/000/000/006/original/example.ppt?1411994371"
Now i want to display those PPT, and PPtx files in my localhost web browser. please give me suggestions.. thanks
Assuming you mean that you want them to be embedded in the browser, I've solved this by uploading the them to Scribd in the background and then displaying the embedded widget. This is a great solution because turning a PPT file into clean HTML is hard (so let someone else work it out), and you do not have to pay for hosting or bandwidth for those files.
It's a lot nicer to do it this way than to force the user to have an Office plugin installed for their browser, which depending on their platform they may not have.
The Scribd_fu gem will work with Paperclip, or you could use the official RScribd gem and roll your own.
I checked previous questions here on SO but I think I want my functionality to work a little different. I understand that .tif files are not natively supported in Internet Explorer and that an extension, such as AlternaTIFF, are available to remedy this. However, I would like the dialog to show up where the user can either save/open the file on the client side. I know that MS Windows Picture and Fax Viewer can open them, no problems.
The files are located on our servers and this will be an intranet site. Currently, I have a link to the files populate in the view but again, I'd like that option for the user to Save/Open the file.
I'm using MVC, which I'm a little unfamiliar with, and can't seem to figure this one out. Thank you.
You can do an action that returns a tiff by changing the headers so when someone clicks the link the file will get downloaded or using FileResult.
Example with FileResult (i find it easier): http://www.dotnetcurry.com/ShowArticle.aspx?ID=807
For saving them is just like uploading any file with MVC. This post can be useful http://haacked.com/archive/2010/07/16/uploading-files-with-aspnetmvc.aspx
My advice is that you convert them to .jpg or .png when uploaded using GDI+.
//You first upload the tiff to the server like the post above explains
//And then open and convert it to .JPEG
Bitmap bm = Bitmap.FromFile("mypic.tiff");
bm.Save("mypic.jpg",ImageFormat.JPEG);
And if you already have the urls of all the tiffs, you can always do a console app to convert all of them. Even if you need to use tiffs its a good idea to have .jpg versions to show on the web. You can even resize them to create previews and save some bandwith too! :-)
For a project we need to download and save pdf files on an IPAD device for offline use through an AIR for iOs application.
After a lot of searching I haven't found much information on this subject. My question is, can it be done, and if so, can you provide us with some pointers to lead us in the right direction.
Thanks for your time!
Sure, first you check if you can access the web - can use a class like air.net.URLMonitor, if you can you can set up a URLStream instance.
You get data while its downloading the file using the progress event, write that out to a File instance using the FileStream class.
To display the PDF file you can use a StageWebView or HTMLLoader.
