Question

I am creating PDFs from xml I am looking for an API which also allows me to rotate text, Is there any API available for .net?

Answer 1

Assuming that you are going to use the library iTextSharp, as suggested in another answer (iText is a Java library; iTextSharp is a .NET port of it), here’s some examples. These are essentially stripped-down versions from Bruno Lowagie’s book iText in Action from Manning Publications.

(Note that the examples are written in Java, since I took them straight from the book, but you should be able to easily adapt them to the iTextSharp library and C#.)

Image rotation:

This is found in the book on page 155.

Image img = Image.getInstance("foo.jpg");
img.setRotationDegrees(45);

Text rotation:

This is found in the book on page 351-352.

PdfContentByte cb = ...;
cb.showTextAligned(PdfContentByte.ALIGN_LEFT, "Some text", e, f, angle);

where e and f are translation values (the coordinates, essentially), and angle is the rotation angle.
