PdfPage.Transform Method 

Transform the page contents by the specific PdfMatrix.

Syntax
C#
Copy
 public void Transform(
   PdfMatrix matrix
);

Parameters

matrix
The transformation matrix.
Remarks

The transformation can scale, translate, rotate, or skew page contents. For example, the following code rotates the page contents by 30 degrees clockwise:

Copy
//Rotate page contents by 30 degrees clockwise
PdfMatrix matrix = new PdfMatrix();
matrix.Rotate(-30);
pdfPage.Transform(matrix);

Please note:

  1. PDF page Y coordinates is from bottom to top. Thus you must use a negative offset Y value to move the contents downwards. For example, the following matrix moves the page contents downwards for one inch:

    Copy
    //Matrix to move contents downwards for one inch
matrix.Translate(0, -72);

    The default unit is 1/72 inch.

  2. Negative degrees rotate contents clockwise, positive degrees rotate contents counter clockwise. For example, the following matrix rotates the page contents 30 degrees clockwise:

    Copy
    //Matrix to rotate the page contents 30 degrees clockwise
matrix.Rotate(-30);

    The coordinate origin is the bottom left corner of the page.

The following code rotate the page 180 degrees:

Copy
PdfMatrix matrix = new PdfMatrix();
matrix.Rotate(180);
matrix.Translate(-612, -792);
pdfPage.Transform(matrix);

Note that you must also call Translate to translate the matrix sicne the coordinate origin is at the bottom left corner of the page. The exact translate amount depends on the size of the page. The above value is for page size 8.5 inch by 11 inch (612 = 8.5 * 72, 792 = 11 * 72).
