Possible to put vector graphics into PDF?

Technical Support Apryse SDK

I know I can easily put bitmaps into a PDF. I know I can programmatically create vector art. But what I am looking for is an approach to embedding a vector artwork file into the PDF.

Comes down to logos and the tradeoff between size and resolution. If there were a way I could export vector art from Corel (my weapon of choice for logos) and export some format of vector file, rather than bitmap, I could reduce the size of the PDF file, and very likely improve the image quality throughout. Win-Win! Just don't know how to add an external vector format logo via PDFTron.

Yes, this is definitely possible and there are multiple ways to do it.

One option is ElementBuilder/ElementWriter as shown in ElementBuilder sample:

http://www.pdftron.com/pdfnet/samplecode.html#ElementBuilder

…

ElementBuilder eb = new ElementBuilder();

ElementWriter writer = new ElementWriter();

page = doc.PageCreate(new Rect(0, 0, 612, 794));

writer.Begin(page);

eb.PathBegin(); // start constructing the path

eb.MoveTo(306, 396);

eb.CurveTo(681, 771, 399.75, 864.75, 306, 771);

eb.CurveTo(212.25, 864.75, -69, 771, 306, 396);

eb.ClosePath();

element = eb.PathEnd(); // the path is now finished

element.SetPathFill(true);

// Set the path color space and color

gstate = element.GetGState();

gstate.SetFillColorSpace(ColorSpace.CreateDeviceCMYK());

gstate.SetFillColor(new ColorPt(1, 0, 0, 0)); // cyan

gstate.SetTransform(0.5, 0, 0, 0.5, -20, 300);

writer.WritePlacedElement(element);

…

Another option is to load vector graphics say from XAML (see Xaml2Pdf sample - http://www.pdftron.com/pdfnet/samplecode.html#Xaml2Pdf), EMF/WMF (pdftron.PDF.Convert.FromEmf()), or via GDI/GDI+ (see PDFDC sample http://www.pdftron.com/pdfnet/samplecode/PDFDCTest.cs).
