Hi

Can somebody confirm if this code is correct for filling an entire A4 page using an image (not using original aspect ratio of the image):

Code:
Image image = section.AddImage(fileName);
//DIN A4. Width is 21 cm, height is 29.7 cm.
image.Height = "29.7cm";
image.Width = "21cm";
image.RelativeHorizontal = RelativeHorizontal.Page;
image.RelativeVertical = RelativeVertical.Page;
image.Top = ShapePosition.Top;
image.Left = ShapePosition.Left;


Is there something missing in the code or wrong. Or is 100% correctly to do this?

If I add an image like this, a previous page of the PDF is overwritten by the image.

Why is that?

I tried creating a new section before adding the image and adding the image to the new section, but it doesn't work.

You do not add a pagebreak before adding the image, so the image is added to the current page and there may be some overlaps with other contents.
No need to add a new section if you only want a new page.

If I make a new paragraph just before adding the image, is the pagebreak needed then?

I'd have to run that code on my computer to confirm it. But why should I spend 20 minutes to turn this code snippet into a program and try it?

But maybe someone else will confirm it.

Because I trust you, you have experience with MigraDoc :D If you say it works, then I better believe it. I'm not sure because I can't see if the image is really completely drawn (but I don't see page background anymore)

Code looks good, but without testing it in a debugger I cannot be sure it actually works.
I produced lots of code that didn't work as expected. :wink:
