  • Extracting text from PDF with Poppler (C++)

    - by nico
    I'm trying to get my way through Poppler and its (lack of) documentation. What I want to do is a very simple thing: open a PDF file and read the text in it. I'm then going to process the text, but that doesn't really matter here. So... I saw the poppler_page_get_text function, and it kind of works, but I have to specify a selection rectangle, which is not very handy. Isn't there just a very simple function that would output the PDF text in order (maybe line by line?). Thank you Nicola

  • .NET component for conversion to PDF

    - by Anvar
    Hi, I am looking for .NET component to convert different files into PDF format. Right now I need to be able to convert programmatically doc, xls and TIFF files to PDF. But I may need to deal with more file types in near future. I looked at Aspose.Words, it works good but for doc only. Is there any component on the market that would allow me to convert in my code all three file types? I would appreciate your suggestions. Thanks, Anvar

  • Rotate view of PDF on a WinForm

    - by Dabas
    I have to display a PDF inside a winform (c# on .net 2.0 framework). For now, I am using the ActiveX PDF control provided by Adobe. I have to disable the entire control so that a user can't print or save via right-click or hotkeys. Unfortunately, many of the documents need to be rotated (just viewed, not permanently saved that way). I'd like to allow them to rotate the view by pressing a button control. I've tried enabling the control then programmatically sending the hotkeys (ctrl shift +) using SendKeys and SendInput but the timing issues make this a non-viable solution. I've asked on the proper Adobe boards and they said it was not possible being that all of my clients will only have the reader version installed.

  • Extract text and image from a pdf in a selected area or coordinates

    - by yercaudARUN
    Hi All, I have a specific requirement of extracting text and images from a specific area in a pdf file.The area might be a selected or highlighted or from a given set of coordinates. When i went through, all the approaches are to extract images and text entirely from the PDF on not in a specified location. I tried with iTextSharp,Syncfussion,Apose but couldn figure out a better approach for this. If somebody could help me out in this it would be greatfull. Can you share your ideas and suggestion on how to implement this in .net. Regards, Arun.M

  • problem with generating PDF and session_start()

    - by gillian
    Hi All, I've been using PDF class produced by R&OS successfully in a number of recent developments. I'd like to use it in a page that performs a database query before generating a PDF (it's basically a summary of the session, so I'm using session_id() as part of the query) All is fine if I run this in Firefox - not fine in IE. I think the loading of session_start() is doing something with headers that's upsetting IE as it appears unable to load the page (comment off session_start and the page loads fine). I'm getting a little concerned as, on further investigation, it appears that R&OS is not supported ... bad newbie learning experience and I really don't want to have to try adopt another class system this late in the day. Have you any thoughts as to what I could try next? Thankx G

  • Question creating PDF document in Zend Framework

    - by deaddancer
    I need to take a ZF rendered view and create a PDF that should look pretty much exactly the same, and email it. The major issue I have right now is getting the HTML created by the view into a string that I can then process with the Zend_PDF::parse method. The view I need to turn into a PDF is the result of a posted form. I've tried grabbing the contents of ob_get_contents into a string after a successful post, but for some reason its not in there. Should I press on with this angle? Any help would be greatly appreciated!

  • SQL Server and the XML Data Type : Data Manipulation

    The introduction of the xml data type, with its own set of methods for processing xml data, made it possible for SQL Server developers to create columns and variables of the type xml. Deanna Dicken examines the modify() method, which provides for data manipulation of the XML data stored in the xml data type via XML DML statements.

  • Array manipulation in gsettings' set command

    - by Daniel
    Is there an easy way to do array manipulation in gsettings? I am comparing gsettings to OS X's defaults command that offers the defaults domain --array key overwrite-value and defaults domain --array-add key added-value interface for manipulating arrays. As far as I can tell there is only gsettings set domain key "['overwrite-value']" available to gsettings. Not really pretty for when you want to add or remove one entry from an array. I have seen a suggestion that allow me to add to an array, but I would rather use a interface if there is one.

  • Resizing pages in Adobe Acrobat Pro

    - by KP
    I am using Acrobat Professional 8 to assemble a document from two imported page images (JPGs). Acrobat seems to interpret the images at screen resolution, and creates a document that's about 35" by 46" instead of 8.5" x 11". How can I scale down the page size within Acrobat?

  • Tip: Keeping the ADF Mobile PDF Guide up to date

    - by Chris Muir
    This is a little tip for customers using Oracle's ADF Mobile. If you're like me, it's possible you don't rely on the online HTML version of the Mobile Developer's Guide for ADF, but rather download a PDF version of the file to use locally (look to the "PDF" link to the top right of the guide).  For me the convenience of the PDF is it's faster, I can search the whole document easily, I can split read the document across two pages on my home monitor, if I lose my internet connection the document is still available, and it's easy to read on my iPad (especially on long haul flights to the US across the Pacific where there is no internet connection!). The trigger point for me to download the Oracle PDF documentation has always been on a new point release of JDeveloper.  However in the case of ADF Mobile, as an extension to JDeveloper it is releasing at a much faster and independent schedule to JDeveloper and this includes updates to the documentation. As such the 11.1.2.4.0 ADF Mobile PDF guide you have locally might be out of date and you should take the opportunity to download the latest version.  This is also particularly important for ADF Mobile as not only are many new features being added for each release and included in the new documentation, but the guide is under rapid improvement to clarify much of what has been written to date.  Our documentation teams are super responsive to suggestions on how to improve the guides and this often shows per point release. How do you tell you've the latest guide? Look to the document part number which right now is "E24475-03".  This is a unique ID per release for the document, the first part being the document number, and the part after the dash the revision number.  If the website document number has a higher revision number, time to download a new up to date PDF. One last thing to share, you can follow the ADF Mobile guide document manager Brian Duffield on Twitter to keep abreast of updates. Image courtesy of Stuart Miles / FreeDigitalPhotos.net

  • PDF export printing in Internet Explorer [closed]

    - by user619804
    protected static byte[] exportReportToPdf(JasperPrint jasperPrint) throws JRException { JRPdfExporter exporter = new JRPdfExporter(); ByteArrayOutputStream baos = new ByteArrayOutputStream(); exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint); exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, baos); exporter.setParameter(JRPdfExporterParameter.PDF_JAVASCRIPT, "this.print({bUI: true,bSilent: false,bShrinkToFit: true});"); exporter.exportReport(); return baos.toByteArray(); } We are using code like this to export a PDF document from a Jasper application. The line exporter.setParameter(JRPdfExporterParameter.PDF_JAVASCRIPT, "this.print({bUI: true,bSilent: false,bShrinkToFit: true});"); adds JavaScript to send the PDF document directly to the printer. The expected behavior is that a print dialog will come up with a preview of the PDF document. This works fine most of the time - except I am having problems about one out of every 5-6 times in Internet Explorer 8 and Firefox. What happens is - the print preview dialog with the PDF document does not appear or it appears with a blank document in the preview window. -I've tried a number of different JavaScripts (different params to this.print() via exporter.setParameter -I've tried setting different response headers such as response.setContentType("application/pdf"); response.setHeader("Content-disposition","inline; filename=\"" + reportName + "\""); response.setContentLength(baos.size()); these did not seem to help This seems to be an IE and FF issue. Has anyone ever dealt with this problem? I need to get it to work across all browsers 100% of the time. Perhaps a different approach to accomplish the goal of sending the PDF document export directly to the printer? or a third party library that will work across browsers?

  • Which type of file parsing easiest and efficient and good ?(html,pdf,csv,text)

    - by Harikrishna
    I want to parse the html file, pdf file, csv file and text file. Now parsing for which type of file (specified above) is easiest and efficient ? Like parsing for html file is easiest and efficient OR parsing for pdf file is easiest and efficient OR parsing for csv file is easiest and efficient ? I am asking this question because I want to parse pdf ,html ,csv and text file through common parsing code if possible. And now suppose if parsing for html is easiest and efficient then : I will write the parsing code for html file and will try to convert pdf file to the html file(if possible)so the code written for parsing html file will also work for pdf file also. And thus I will try to convert pdf,csv and text file to html file.And write the code for parsing html file and thus this code will parse html,pdf,csv and text file. Suppose if parsing for pdf is easiest and efficient then : I will convert html,csv and text file to pdf and write the code for parsing pdf file.So the code for parsing pdf file can parse html,csv and text file. So my question is (1) Which type of file parsing is easiest and efficient (pdf,csv,html,text) ? (2) And converting files(pdf,text,html,csv) to eachother is possible. Like if html parsing easiest then pdf to html,text to html and csv to html.

  • FPDI - SELECT WHICH PDFS TO SHOW

    - by NORM
    IS THERE A WAY FOR A OPTION TO SELECT WHICH PDFS TO SHOW WITH THE FPDI FUNCTION? THIS IS THE REGULAR CODE: $pdf-AddPage(); // set the sourcefile $pdf-setSourceFile('h.pdf'); // import page 1 $tplIdx = $pdf-importPage(1); // use the imported page and place it at point 10,10 with a width of 100 mm $pdf-useTemplate($tplIdx, 0, 0, 0); Is there a way to make this $pdf-setSourceFile('h.pdf'); a option for users who visit the website. For example: have - $pdf-setSourceFile('h.pdf'); & $pdf-setSourceFile('g.pdf'); - then let the visitor select which one to include in the pdf via fpdi. I would prefer something like a input. Any ideas?? or something similar??? Help is very much appreciated!! :D

  • PDFtk Password Protection Help

    - by Dave W.
    I am using Ubuntu 11.10 and am looking for a solution to password protect a bunch of pdf files in a directory in batch. I came across PDFtk and it looks like it might do what I need, but I've reviewed the command line PDFtk examples and can't figure out if there is a way to do it in batch without having to individually specify the output file name for every file. I'm hoping a command-line guru can take a look at the PDFtk syntax and tell me if there is some trick / command that will allow me to password protect a directory of pdf files (e.g., *.pdf) and overwrite the existing files using the same name, or consistently rename the individual output files without having to specify each output name individually. Here's a link to the PDFtk command line examples page: http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/ Thanks for your help. I think I've answered my own question. Here's a bash script that appears to do the trick. I'd welcome help evaluating why the code I've commented out doesn't work... #!/bin/bash # Created by Dave, 2012-02-23 # This script uses PDFtk to password protect every PDF file # in the directory specified. The script creates a directory named "protected_[DATE]" # to hold the password protected version of the files. # # I'm using the "user_pw" parameter, # which means no one will be able to open or view the file without # the password. # # PDFtk must be installed for this script to work. # # Usage: ./protect_with_pdftk.bsh [FILE(S)] # [FILE(S)] can use wildcard expansion (e.g., *.pdf) # This part isn't working.... ignore. The goal is to avoid errors if the # directory to be created already exists by only attempting to create # it if it doesn't exists # #TARGET_DIR="protected_$(date +%F)" #if [ -d "$TARGET_DIR" ] #then #echo # echo "$TARGET_DIR directory exists!" #else #echo # echo "$TARGET_DIR directory does not exist!" #fi # mkdir protected_$(date +%F) for i in *pdf ; do pdftk "$i" output "./protected_$(date +%F)/$i" user_pw [PASSWORD]; done echo "Complete. Output is in the directory: ./protected_$(date +%F)"

  • PDF rendering crashes app Core Graphics

    - by Felixyz
    EDIT: The memory leaks turned out to be unrelated to the crashes. Leaks are fixed but crashes remain, still mysterious. My (iPhone) app does lots of PDF loading and rendering, some of it threaded. Sometime, it seems always after I flush a page cash after getting a memory warning, the app crashes with a bad access when trying to draw a pdf page stored in an NSData object. Here is one example trace: #0 0x3016d564 in CGPDFResourcesGetResource () #1 0x3016d58a in CGPDFResourcesGetResource () #2 0x3016d94e in CGPDFResourcesGetExtGState () #3 0x3015fac4 in CGPDFContentStreamGetExtGState () #4 0x301629a8 in op_gs () #5 0x3016df12 in handle_xname () #6 0x3016dd9e in read_objects () #7 0x3016de6c in CGPDFScannerScan () #8 0x30161e34 in CGPDFDrawingContextDraw () #9 0x3016a9dc in CGContextDrawPDFPage () But sometimes I get this instead: Program received signal: “EXC_BAD_ACCESS”. (gdb) bt #0 0x335625fa in objc_msgSend () #1 0x32c04eba in CFDictionaryGetValue () #2 0x3016d500 in get_value () #3 0x3016d5d6 in CGPDFResourcesGetFont () #4 0x3015fbb4 in CGPDFContentStreamGetFont () #5 0x30163480 in op_Tf () #6 0x3016df12 in handle_xname () #7 0x3016dd9e in read_objects () #8 0x3016de6c in CGPDFScannerScan () #9 0x30161e34 in CGPDFDrawingContextDraw () #10 0x3016a9dc in CGContextDrawPDFPage () Is this an indication that I've mistakenly deallocated an object? It's hard for me to decode what's happening here. This is how I create and retain the various objects involved: // Some data was just loaded from the network and is pointed to by "data" self.pdfData = data; _dataProviderRef = CGDataProviderCreateWithData( NULL, [_pdfData bytes], [_pdfData length], NULL ); _documentRef = CGPDFDocumentCreateWithProvider(_dataProviderRef); _pageRef = CGPDFDocumentGetPage(_documentRef, 1); CGPDFPageRetain(_pageRef); _pdfFrame = CGPDFPageGetBoxRect(_pageRef, kCGPDFArtBox); So the NSData object is retained, and I explicitly retain the page reference. The data provider and the document are already retained by the create-functions. And here is my dealloc method: -(void)dealloc { if (_pageRef) CGPDFPageRelease(_pageRef); if (_documentRef) CGPDFDocumentRelease(_documentRef); if (_dataProviderRef) CGDataProviderRelease(_dataProviderRef); self.pdfData = nil; [super dealloc]; } Am I doing anything wrong? Even an assurance that I'm not, with explanation, would be a help.

  • Using Ghostscript in a Webapplication (PDF Thumbnails)

    - by cpt.oneeye
    Hello, i am using the ghostscriptsharp wrapper for c# and ghostscript. I want to generate thumbnails out of pdf-files. Further Information on the sample-code are given here. There are different Methods imported form the ghostscript-c-dll "gsdll32.dll". [DllImport("gsdll32.dll", EntryPoint = "gsapi_new_instance")] private static extern int CreateAPIInstance(out IntPtr pinstance, IntPtr caller_handle); [DllImport("gsdll32.dll", EntryPoint = "gsapi_init_with_args")] private static extern int InitAPI(IntPtr instance, int argc, IntPtr argv); //...and so on I am using the GhostscriptWrapper for generating the thumbnails in a webapplication (.net 2.0). This class uses the methods imported above. protected void Page_Load(object sender, EventArgs e){ GhostscriptWrapper.GeneratePageThumb("c:\\sample.pdf", "c:\\sample.jpg", 1, 100, 100); } When i debug the Web-Application in Visual Studio 2008 by hitting key "F5" it works fine (a new instance of webserver is generated). When i create a WindowsForm Application it works too. The thumbnails get generated. When i access the application with the webbrowser directly (http://localhoast/mywebappliation/..) it doesn't work. No thumbnails are generated. But there is also no exception thrown. I placed the gsdll32.dll in the system32-folder of windows xp. The Ghostscript Runtime is installed too. I have given full access in the IIS-Webproject (.Net 2.0). Does anybody know why i can't access Ghostscript from my webapplication? Are there any security-issues for accessing dll-files on the IIS-Server? Greetings Klaus

  • PDF files created on iPad dont display correctly on Windows

    - by user286028
    My iPhone app creates PDF files (in Arial font). The plain iPhone 3.1.x version works great (other than the known issue that PDFs created on the iPhone cant be viewed correctly in Google Docs or the BlackBerry). As I am updating my project for OS 3.2 and the iPad, it works just the same, and the PDFs still look great on the iPhone, iPad and MacOS (Preview app). But now on Windows (Vista), Acrobat 9.3.1 says "Cannot extract the embedded font 'XYZABC+ArialMT'. Some characters may not display or print correctly". And in fact Acrobat then uses some generic font instead of Arial (or whatever other font I try). Quartz 3.2 seems to generate these "random" embedded font names each time it creates a PDF (the XYZABC changes around each time). I can't tell whether the problem is just the somewhat strange "temporary" embedded font name with the plus sign, or the way Quartz 3.2 is embedding fonts. I have tried my existing code (using CGPDFContext* funtions), and also the newly supported UIGraphics* functions, with the same results. Has anyone else tried creating PDFs on the iPad yet and gotten them to display correctly on Windows?

  • Increase performance on iphone at pdf rendering

    Hi! I have a UITableView, and in every cell there's displayed a UIImage created from a pdf. But now the performance is very bad. Here's my code I use to generate the UIImage from the PDF. Creating CGPDFDocumentRef and UIImageView (in cellForRowAtIndexPath method): ...

  • Saving "heavy" figure to PDF in MATLAB - rendering problem

    - by yuk
    I generate a figure in MATLAB with lot amount of points (100000+) and want to save it into a PDF file. With zbuffer or painters renderer I've got very large and slowly opened file (over 4 Mb) - all points are in vector format. Using OpenGL renderer rasterize the figure in PDF, ok for the plot, but not good for text labels. The file size is about 150 Kb. Try this simplified code, for example: x=linspace(1,10,100000); y=sin(x)+randn(size(x)); plot(x,y,'.') set(gcf,'Renderer','zbuffer') print -dpdf -r300 testpdf_zb set(gcf,'Renderer','painters') print -dpdf -r300 testpdf_pa set(gcf,'Renderer','opengl') print -dpdf -r300 testpdf_op The actual figure is much more complex with several axes and different types of plots. Is there a way to rasterize the figure, but keep text labels as vectors? Another problem with OpenGL is that is does not work in terminal mode (-nosplash -nodesktop) under Mac OSX. Looks like OpenGL is not supported. I have to use terminal mode for automation. The MATLAB version I run is 2007b. Mac OSX server 10.4.
