This example shows how to create a PDF document rotated by 90 degrees for a landscape rather than portrait view.
|
Setup
|
We start by creating a PDF document. We use two transforms to apply a generic 90 degree rotation around the center of the document and rotate the drawing rectangle by the same amount. After applying our rotation we add some text to the page.
using var doc = new Doc();
// apply a rotation transform
double w = doc.MediaBox.Width;
double h = doc.MediaBox.Height;
double l = doc.MediaBox.Left;
double b = doc.MediaBox.Bottom;
doc.Transform.Rotate(90, l, b);
doc.Transform.Translate(w, 0);
// rotate our rectangle
doc.Rect.Width = h;
doc.Rect.Height = w;
// add some text
doc.Rect.Inset(50, 50);
doc.FontSize = 96;
doc.AddText("Landscape Orientation");
|
Rotate
|
Drawing the text rotated does not rotate the page itself. To change the default orientation of the document we need to apply a rotation to the root page object. By doing this we ensure that every page in the document is viewed rotated.
// adjust the default rotation and save
int id = doc.GetInfoInt(doc.Root, "Pages");
doc.SetInfo(id, "/Rotate", "90");
doc.Save(Server.MapPath("landscape.pdf"));
