pdf

问题 For some reason, when converting an HTML file to a PDF in Google Apps Script, the file size of the PDF ends up being way bigger than the original HTML file. The code I used to run the test is below: function convertHTMLtoPDF() { // convert a specific message with an attached HTML file to PDF, // and save it to the root directory of Google Drive var threads = GmailApp.search('subject:(Sample HTML)'); var message = threads[0].getMessages()[0]; var attachmentName = message.getAttachments()[0]

问题 Currently I am using a custom LocationTextExtractionStrategy to extract text from a PDF that returns a TextRenderInfo[]. I would like to be able to determine if a TextRenderInfo object (or PDFString, child of TextRenderInfo) appears in a specific layer. I am not sure if this is possible. To get the layers in a PDF, I am using: Dictionary<string,PdfLayer> layers; using (var pdfReader = new PdfReader(src)) { var newSrc = Path.Combine(["new file location"]); using (var stream = new FileStream

问题 I want to create a simple PDF Viewer inside my Qt Application. Everything works fine, accept opening the PDF at a specific page over the URL. For example: url = "file:///D://Repo//PdfViewer//PdfViewer//test.pdf"; Works, but url = "file:///D://Repo//PdfViewer//PdfViewer//test.pdf#page=9"; dosent. I read somewhere, that chrome dosent offically support #page=x anymore, but I cant find futher information how to solve this. I face the same problem with this url in the Nano-Browser Example from Qt.

问题 I'm aware of pdf-stamper, but I'm trying to avoid switching everything to jruby right now. I just need to "stamp" an image that I generate within the rails app (a PDF417 barcode) into a form field in the PDF document (there's an FDF; it's a document template kinda thing). I'm filling out the text-based fields by just shelling out to pdftk, so if there's a way to do it using pdftk, I'd be fine with that, but I've looked high and low for one without any luck. 回答1: How about using a barcode font

问题 I am writing mailmerge software as part of a Python web app. I have a template called letter.pdf which was generated from a MS Word file and includes the text {name} where the resident's name will go. I also have a list of c. 100 residents' names.

I then want to gather all these pdfs togetherinot a big pdf (one page per letter)

问题 Is there some way to extract "alternate text" for a specific image using PDFBox? I have a PDF file which, as described at http://www.w3.org/WAI/GL/2011/WD-WCAG20-TECHS-20110621/pdf.html#PDF1, has had alternate text added to an image. Using PDFBox I can find my way through the object model to the image itself (a PDXObjectImage) through PDFDocument.getDocumentCatalog().getAllPages() [iterator] .getResources.getImages() but I can not see any way to get from the image itself to the alternate text
