PDF Rendering Example

This example shows how to render a PDF document.

For an example of how to render a PDF direct to screen and how to print a PDF see the ABCpdfView project and classes under the ABCpdf menu item.

Read

We create an ABCpdf Doc object and read our source PDF.

using Doc doc = new Doc();
doc.Read(Server.MapPath("../Rez/spaceshuttle.pdf"));

Dim doc As New Doc()
doc.Read(Server.MapPath("../Rez/spaceshuttle.pdf"))

Prefs

We specify our base rendering settings.

doc.Rendering.DotsPerInch = 36;

doc.Rendering.DotsPerInch = 36

Save

Finally we save the first four pages of the document in png format.

for (int i = 1; i <= 4; i++) {
  doc.PageNumber = i;
  doc.Rect.String = doc.CropBox.String;
  doc.Rendering.Save(Server.MapPath("shuttle_p" + i.ToString() + ".png"));
}

Dim i As Integer = 1
While i <= 4
  doc.PageNumber = i
  doc.Rect.String = doc.CropBox.[String]
  doc.Rendering.Save(Server.MapPath("shuttle_p" + i.ToString() + ".png"))
  System.Math.Max(System.Threading.Interlocked.Increment(i),i - 1)
End While
