How can I use RenderPageToDC on Mac?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I use methods RenderPageToDC, SetRenderDCOffset and SetRenderScale on windows platform. The "Debenu Quick PDF Library 9.15 Mac Reference Guide.pdf" contains functions RenderPageToDC, SetRenderDCOffset, SetRenderScale. What is "DC - The device context handle" on mac? CGConextRef?  Can you tell how to use it, or to show an example?
Your readme.txt contains: "The Mac version of the library is still in beta and is missing a few of the features that the Windows version has. The following functions are not currently supported in the Mac version:AddSubsettedFont
...
AddTrueTypeSubsettedFont
DARenderPageToDC
...
PrintDocument
PrintOptions
..."
is this true?
If it's true, then when will they become available?

	Hi Alexander, Thanks for your email. > What is “DC – The device context handle” on mac? > CGConextRef? Can you tell how to use it, or to > show an example? You can get the device context on Mac using CGContextRef. We don’t have any sample code for this at the moment but I’ll see if we can create some for you today to help you get started. We hope to add support for the other functions in the Ma version later in the year. Cheers, - Rowan.

	I'm sorry, can I ask one more question? In readme.txt: The dylib for Debenu Quick PDF Library is 32-bit only and so the XCode project must be set to 32-bit mode. When you plan to release a 64 bit version? thank you very much Cheers

	example 1: _QP = new DebenuPDFLibraryDylibCPPClass0915(dllFileName); if (!_QP->LibraryLoaded()) { return; } if (_QP->UnlockKey(strLicenseKey) != 1) { return ; } if (_QP->LoadFromFile(L"/Users/aleksandr/Desktop/debenu_quick_pdf_library_mac/license.pdf", L"") == 0) { return; } currentDocumentID =_QP->SelectedDocument(); _QP->SetRenderDCErasePage(1); std::cout << "PdfTool::openFile: SelectedDocument = " << currentDocumentID << std::endl; std::cout << "PdfTool::openFile: DocumentCount = " << _QP->DocumentCount() << std::endl; std::cout << "PdfTool::openFile: PageCount = " << _QP->PageCount() << std::endl; std::cout << "_QP->SelectPage="<< _QP->SelectPage(1) << std::endl; std::cout << "_QP->SelectedPage=" << _QP->SelectedPage() << std::endl; std::cout << "_QP->PageWidth="<< _QP->PageWidth() << std::endl; std::cout << "_QP->PageHeight="<< _QP->PageHeight() << std::endl; _QP->SetRenderScale(1.0); std::string buf = _QP->RenderPageToString(72, 1 , 5); example 2: - (void)drawRect:(NSRect)dirtyRect { // Drawing code here. // Get current context CGContextRef context = (CGContextRef)[[NSGraphicsContext currentContext] graphicsPort]; _QP->RenderPageToDC( 72, 1, (int)context); } RenderPageToString and RenderPageToDC do not work!
