Hi,

I want to insert a vector image in a pdf file but instead of using the original resolution I want to scale it down to a different size. I have this code based on the documentation.

PdfDocument doc = new PdfDocument();

PdfPage page = doc.Pages.Add();

PdfGraphics graphics = page.Graphics;

PdfMetafile metaChart = new PdfMetafile("BoxOk.emf");

PointF drawingCoordinates = new PointF(0, 0);

metaChart.Draw(page, new RectangleF(drawingCoordinates.X, drawingCoordinates.Y + 2, 12, 12));

doc.Save("Output.pdf");

doc.Close(true);

The result however is a 51 page pdf with a small 12 by 12 part of the image on each page. What I need is the complete image scaled down to 12 by 12 only on the first page.

How can this be achieved?

PdfPage page = doc.Pages.Add();

//Create PDF graphics for the page

PdfGraphics graphics = page.Graphics;

//Create a Metafile instance

PdfMetafile metaChart = new PdfMetafile(DataPathBase + "BoxOk.emf");

RectangleF rect = new RectangleF(0, 2, 12, 12);

//Draw the Metafile in the page

graphics.DrawImage(metaChart, rect);

//Save and close the document
