Convert XPS to PDF in WPF C# application

由 时光总嘲笑我的痴心妄想 提交于 2019-12-01 09:13:57
问题 I need to convert an XPS file I create with my application to a PDF file, what is the best way to do so? I prefer this to be done from inside C# using a managed assembly. Open source is preferred upon third party solutions 回答1: You can use the XpsDocument class to read the XPS files, then use a PDF library (such as Report.Net or #PDF) to export it. I used #PDF back in .NET 1.1, but not sure if it can be easily converted to .NET 2.0. #PDF: http://sharppdf.sourceforge.net/ Report.NET: http:/

问题 I need to have a table with multiple columns where I have different coloured circles in different cells with a number in the middle of the circle.

Calculate correct width of a text

由 烈酒焚心 提交于 2019-12-01 08:16:08
问题 I need to read a plan exported by AutoCAD to PDF and place some markers with text on it with PDFBox. Everything works fine, except the calculation of the width of the text, which is written next to the markers. I skimmed through the whole PDF specification and read in detail the parts, which deal with the graphic and the text, but to no avail. As far as I understand, the glyph coordinate space is set up in a 1/1000 of the user coordinate space. Hence the width need to be scale up by 1000, but

Write PDF text to a PDFContext in iOS

由 天涯浪子 提交于 2019-12-01 08:02:28
It's pretty trivial to draw to a pdf context via: UIGraphicsBeginPDFContextToFile(pdfFile, CGRectZero, nil); UIGraphicsBeginPDFPageWithInfo(sheet.frame, nil); CGContextRef ctx = UIGraphicsGetCurrentContext(); CGRect text_rect = ... NSFont *font = ... NSString * str = @"foo"; [str drawInRect:text_rect withFont:font]; ...draw to context... However the text is clearly rasterized... Is there anyway to actually add pdf style text to a pdf file? So the user can select it, copy it, etc. Possibly through a library other than core graphics? It's definitely possible. Here's a tutorial that shows how to
