I have downloaded and am starting to use wxWidgets 3.0.1 and am trying find support for PDF file formats. I expected there would be a printer like PDF DC.
But I could only find a wxPostcriptDC in the download, and even that is not supported in the wx libraries. Further browsing the Net found a wxWidgets wxPdfDocument class that was apparently part of widgets 2.8 and 9. What has happened to Pdf in wxWidgets 3.0.1? Also wxPdfDocument for wxWidgets 2.9, describes an interface that looks like a 3.0.1 DC BUT does not state that this is so. If I managed to compile it in a 3.0.1 environment, can I use in in my 3.0.1 program as a wxDC derived class?

By the way, there are build files for wxWidgets 3.x available. However, you have to download them from the wxCode SVN: I admit that I should have made a wxPdfDocument file release directly containing the wxWidgets 3.x support files. Regards, Ulrich.

I opted for the following approach: When using PDF you mostly want a printout not to be on paper but in PDF format. I already had the routines to print documents based on database content (the document layout is stored in tables like forms, formobjects, formdatasets etc). So I wanted to use this logic to create the same documents in PDF. So a PDF printerdriver was the most logical step to take. I once wrote code (PHP) to create PDF documents and it is quite a lot of work to create a PDF document step by step. BioPDF for one is quite a good one.
With this I can first create a control file to set things like the filename of background or merging with other PDF. And then print on this PDF printer driver.
Success, Nunki. Code: wxPrintData pd; wxPdfDC. ps = 0; pd. SetPaperId (wxPAPERA4); pd. SetOrientation (wxPORTRAIT); pd. SetFilename ('test.pdf'); wxPrinterDC. pp = new wxPdfDC (pd); ps- SetMapModeStyle (wxPDFMAPMODESTYLEPDF); // so page coordinates are as screen ps- SetMapMode (wxMMTEXT); int nx, ny; cdc- GetSize (& nx, & ny); if (cdc- StartDoc (')).
So that my actual Draw (Screen or Page), function can be unaware of where it is displaying. But when I ran this to get the pdf file the result was not as intended. The attachments are screen shot.png which is the GUI display of the test data (my own open file dialog which am converting to widgets) and test.png which I send instead of test.pdf which was rejected as a file type when I dragged it into this Panel!!!! This shows the original problems discussed below. Firstly I was drawing coloured Highlight behind the text using GradientFillConcenric, but this positioned the rectangle correctly BUT it was too wide and high and tok 30 seconds to write the screen!!
I 'cured' this by switching to GradientFillLiner and that worked Ok I believe you may have a bug in the Concentric Fill. Do I need to do anything further to raise this Bug?
Secondly my pdf output was misaligned. Looking more closely it was only DrawText that was outputting things too High on the 'paper' and I could still see the missing line by looking at the.pdf file with iDraw (a Mac Graphics utility) which displayed the missing text in shadow on the surround of the 'paper'. This I have 'corrected' in my code by adding a fudge of 25 (my CharHeight is 29) to the y wxCoord in DrawText!!!
I wouldn't know how to extend this 'fudge' for screens with several font sizes!! And thirdly my Hebrew text is replaced by Blobs. Is there something I need to preset in building my wxpdf.lib file, to encourage a fuller character set? This is the outline of my text output with background shading and caret.

So that my actual Draw (Screen or Page), function can be unaware of where it is displaying.
But when I ran this to get the pdf file the result was not as intended. Although it should not matter, it could be a side effect of the map mode. I have to admit that I seldom use wxPdfDC myself. For my own applications I usually need the full control about the PDF generation, and therefore use wxPdfDocument directly. That is, it is certainly possible that there are still bugs in wxPdfDC.

Do I need to do anything further to raise this Bug? Well, at the moment the methods GradientFillConcentric and GradientFillLinear both don't have a native wxPdfDocument implementation, so they ressort to the default implementation. For the concentric fill this will draw an enormous number of pixels, which will be very inefficient and slow for the PDF output.
You should probably avoid to use these methods, at least for the PDF output. Jeff Strauss wrote:Secondly my pdf output was misaligned.

I think for the screen output wxDC assumes that the y position is the left upper corner of the text box instead of the base line. This would result in text positioned too high in PDF. I guess you will have to play a bit with the map mode settings to get the expected results. It could be that you need to set the platform dependent map mode style (wxPDFMAPMODESTYLEMSW, wxPDFMAPMODESTYLEGTK, wxPDFMAPMODESTYLEMAC) to get the results as expected.

First, Hebrew is a language that is written from right to left. RTL scripts are currently not supported by wxPdfDocument, unless you handle the glyph positioning yourself in your application. Second, the font used for outputting the text in PDF needs to contain all required glyphs. If the font doesn't contain the necessary glyphs place holders will show up. And that's what you experience. The font used by wxPdfDocument for text output obviously doesn't contain Hebrew glyphs.
You have to set an appropriate font with method wxDC::SetFont at runtime. This is nothing you can influence at compile time.
