Post subject:  Issue when drawing strings on landscape page

Hi,

My designer sent me a couple of PDFs which i should then dynamicaly combine to one pdf (Some pages have Orientation=landscape). On each page i put some additional texts.

When i add lanscape page (rotate=90) to document
var page = Document.AddPage(referencedPage);

rotate=90 stays
Orientation changed to Portrait

The problem is that when i draw string on the landscape page, the added strings are drawn verticaly.

Thank you
David

There is a known problem with rotation.

Maybe this post can help you:

Workaround:
Code:
page.Orientation = PageOrientation.Portrait;

No, this did not solve the issue

you have to rotate the xgraphics object.

Code:
gfx.RotateAtTransform(90, new XPoint(page.Width / 2, page.Height / 2));


the problem is then you are rotating around the wrong point since you are now in landscape. So you need to measure the difference between the center point of the document when in landscape and portrait

Code:
var offset = Math.Abs((page.Height - page.Width))/2;


then shift the document to adjust for the center points

Code:
gfx.TranslateTransform(offset, -offset);


This was from landscape to portrait so you may need to adjust the TranslateTransform. it could be
Code:
gfx.TranslateTransform(-offset, offset);
