 Posted: Mon Jul 21, 2008 9:19 pm Post subject: How to use DrawImage? |
 |
|
This seems like a bug, but there can't be a bug in something this basic, so I must be doing something wrong. In the call xg.DrawImage(img, to, from ,...), it seems like the from argument is just being ignored. Whatever I put there, the entire image is inserted. (I have the identical call with a regular Graphics object, and it works just as expected.)
What am I missing? I can post code if necessary, but it would take a while; I'm hoping the difference between XGraphics.DrawImage and Graphics.DrawImage is clear to someone. Or maybe someone can assure me it actually works perfectly, and I'll just spend more time hacking.
(I have PDFSharp version 1.0.898.0.)

Hi!
I have some bad news for you: look at XGraphicsPdfRenderer.cs, line 643:
| Code: | // TODO: incomplete - srcRect not used
public void DrawImage(XImage image, XRect destRect, XRect srcRect, XGraphicsUnit srcUnit)
|
Sorry, but there is no easy way to do it for PDF (otherwise it would have been implemented a long time ago).
Copy the area you need into a new image and use the new one in PDF.
