There are several ways to create a PDF document in Qt. You already mentioned two of them. I propose some improvement for the QTextDocument approach. Rather than manually writing a QTextDocument, you can create it from HTML-formatted text. QString html = “<div align=right>” “City, 11/11/2015” “</div>” “<div align=left>” “Sender Name<br>” “street 34/56A<br>” “121-43 city” “</div>” … Read more
If you goal is just to view the pdf in your application, the easiest way is using the object tag in HTML. You don’t need to import any libraries and works most of the browsers. But this is lack of customization and styles. <object data=”http://africau.edu/images/default/sample.pdf” type=”application/pdf” width=”100%” height=”100%”> <p>Alternative text – include a link <a … Read more
Create a bookmarklet – a bookmark with the following in the location/address/URL field: javascript:(function(){var el = typeof viewer !== ‘undefined’ ? viewer : document.body; el.style.filter=”grayscale(1) invert(1) sepia(1) contrast(75%)”;})() Then, click on this bookmark after you open a PDF in Firefox.
You can use one commandline with two commands (gs, convert) connected through a pipe, if the first command can write its output to stdout, and if the second one can read its input from stdin. Luckily, gs can write to stdout (… -o %stdout …). Luckily, convert can read from stdin (convert -background transparent – … Read more
Scannned images converted to PDF which have been OCR’ed in the aftermath to make text searchable do normally contain the text parts rendered as “invisible”. So what you see on screen (or on paper when printed) is still the original image. But when you search successfully, you get the hits highlighted that are on the … Read more
I found this page here explaining how scaling works with XSL-FO. Essentially, this is the snippet that I used to make it work: <fo:external-graphic src=”https://stackoverflow.com/questions/6220316/url(“https://stackoverflow.com/questions/6220316/…”)” width=”100%” content-height=”100%” content-width=”scale-to-fit” scaling=”uniform” xsl:use-attribute-sets=”img”/> I found that width=”100%” was the missing piece in your own attempts. Hope this helps future visitors.
The answer can be found in the PDFsharp FAQ list: http://www.pdfsharp.net/wiki/PDFsharpFAQ.ashx#Can_PDFsharp_show_PDF_files_Print_PDF_files_Create_images_from_PDF_files_3 PDFsharp creates PDF files, but it cannot render them. The call Bitmap b = new Bitmap((int) pdfp.Width.Point, (int) pdfp.Height.Point, xgfx.Graphics); does not initialize any bits of the bitmap and does not copy anything from the Graphics object except for the DPI setting of the … Read more
Finding text in a PDF can be inherently hard because of the graphical nature of the document format — the letters you are searching for may not be contiguous in the file. That said, CAM::PDF has some search-replace capabilities and heuristics. Give changepagestring.pl a try and see if it works on your PDFs. To install: … Read more
I’ve used pdftohtml to successfully strip tables out of PDF into CSV. It’s based on Xpdf, which is a more general purpose tool, that includes pdftotext. I just wrap it as a Process.Start call from C#. If you’re looking for something a little more DIY, there’s the iTextSharp library – a port of Java’s iText … Read more
Try this :- <input id=”inputFile” type=”file” onchange=”convertToBase64();” /> <script type=”text/javascript”> function convertToBase64() { //Read File var selectedFile = document.getElementById(“inputFile”).files; //Check File is not Empty if (selectedFile.length > 0) { // Select the very first file from list var fileToLoad = selectedFile[0]; // FileReader function for read the file. var fileReader = new FileReader(); var base64; … Read more
