Metadata in PDF Files

由 荒凉一梦 提交于 2019-12-24 03:02:42
问题 I want to be able to store some plugin-specific data in a PDF so that I can read it back when that PDF is loaded back, without this metadata being visible to the user. How can I put this metadata into the PDF File? 回答1: PDF supports XMP metadata. You should append your plug-in specific information as a payload in the XMP portion. 回答2: Depending on how you are generating and reading your PDFs you can use pdftk to edit your metadata. You can add an invisable tag to the PDF by adding it as a

Cannot use border-radius CSS3 property with Flying Saucer

由 荒凉一梦 提交于 2019-12-24 02:33:08
问题 I am working on a project where I need to convert an HTML to a PDF. I am using Flying Saucer 9.1.6 from Maven Central for this. The subjacent PDF generation library is IText 2.1.7 . Although Flying Saucer Git repo states that it supports CSS3 border-radius syntax I am unable to achieve rounded corners with border-radius. Here is the sample code ITextRenderer pdfRenderer = new ITextRenderer(); String resumeHTML = "<html>\n" + "<head>\n" + " <title>JS Bin</title>\n" + " <style>\n" + " .circle{

How to avoid the “too deeply nested” error when creating PDFs with Sphinx?

由 自古美人都是妖i 提交于 2019-12-24 02:18:57
问题 I have a fairly complex project with a fairly large documentation. Converting the normal user guide to PDF with Sphinx via make latexpdf works quite well. However, if I also want to include the library reference with all function, class, and module documentations, the command fails with: ! LaTeX Error: Too deeply nested. Manually reducing the nesting is not an option. Sphinx internally nests parameter descriptions, function descriptions, module descriptions and whatnot. So figuring out in

Generate PDF with XSL-FO for Android

由 好久不见. 提交于 2019-12-24 02:11:50
问题 Is it possible to generate a PDF in an Android application using XSL-FO? 回答1: Download Apache FOP and see if the required dependencies are includes in Android's runtime. It might be rather slow. You could use iText or PDFBox to render PDF - or use a server and let Android just request a PDF creation. 来源： https://stackoverflow.com/questions/9393679/generate-pdf-with-xsl-fo-for-android

Matplotlib PDF backend slow?

由 守給你的承諾、 提交于 2019-12-23 19:47:36
问题 I'm writing a thousand plots to a PDF using matplotlib. I've already optimized the plotting code, ie. reusing figures/axes/lines and just changing the y data. The bulk of the remaining time is spent in save_figure. R, in comparison, seems to output a plot to PDF about 2x faster. Plots will all zero data seem to be even faster in R, while they're the same speed in Python. I've set pdf.compression = 0, which makes a small improvement. Tried rasterizing the data, it made no difference to

问题 I need to add some formatted text to a PDF form field using iTextSharp and I can't seem to figure it out. This is how I'm currently setting the fields, but certain portions of the inserted text will need to be bold or have other formatting. stamper.AcroFields.SetField("fieldName", "fieldValue") stamper.FormFlattening = True I've seen elsewhere that I should be able to insert some xml that includes formatting information instead, but I have no idea what this xml should look like.
