Generating PDF with Quick Reports behind a Delphi Web Server

由 ＊爱你＆永不变心＊ 提交于 2019-12-09 05:38:23
I have a Delphi web server providing some web services*. One of them is supposed to generate and return a PDF report. The PDF creation is done with a QReport that is then exported into a PDF file with the ExportToFilter procedure. The routine works fine when called from within an application, but when called behind a TIdTCPServer, it hangs and never finishes. Debugging it, I got tho the hanging point: (note: I'm home right now and I don't have the source code. I'll try to reproduce quickrpt.pas' source as accurrate as I can remember). procedure TCustomReport.ExportToFilter(TQRDocumentFilter

PDFsharp on Azure with Custom Fonts

由 谁说胖子不能爱 提交于 2019-12-09 03:15:31
I am using a webapp on azure to create a PDF using PDFsharp 1.32. As it is a Azure webapp I cannot install fonts. Therefore I am using the following with embedded font options: var globalFontCollection = XPrivateFontCollection.Global; _fontBytes = File.ReadAllBytes(_pathToFont); globalFontCollection.AddFont(_fontBytes, _fontName); However this does not work. There is no error just acts as if the font is not known and falls back to the default. If I install the font it works so I know the rest of the code is correct. Other code shows using AddFont with different parameters however those are not

问题 I'm using flyingsaucer to render an xhtml document to pdf through a servlet which returns the generated pdf document. The xhtml document features an image which is requested from another servlet.
