I have a pdf , and I want to get the width and Height for each page in pdf using iTextSharp?
given this is the pdf I want to work with
string source=@"D:\pdf\test.pdf";
PdfReader reader = new PdfReader(source);
Do you want the MediaBox?
Rectangle mediabox = reader.GetPageSize(page);
Do you want the rotation?
int rotation = reader.GetPageRotation(page);
Do you want the combination of both?
Rectangle pagesize = reader.GetPageSizeWithRotation(page);
Do you want the CropBox?
Rectangle cropbox = reader.GetCropBox(page);
Most of them return an object of type Rectangle that has methods such as getWidth() and getHeight() to get the width and the height of the page.
Other useful methods are getLeft() and getRight() as well as getTop() and getBottom(). These four methods return the x and y coordinates that define the boundaries of your page.
Where did I find most of this documentation?
In chapter 6 of iText in Action.
