I am using aspose.pdf for cropping pdf from a region. following code I have used for cropping the pdf

Document document = new Document(AppDomain.CurrentDomain.BaseDirectory + “A1.pdf”);
PageCollection coll = document.Pages;
Aspose.Pdf.Rectangle pageRect = new Aspose.Pdf.Rectangle(30, 0, 690, 600);
document.Pages[1].CropBox = pageRect;
document.Save(AppDomain.CurrentDomain.BaseDirectory + “A2.pdf”);

in pdf rectangle I am passing values as
llx=left margin;
lly=margin from bottom
urx=width of article
ury=height of article

but not getting right area but converting pdf to html using aspose with same value getting the right article.

Hi Devinder,


Thanks for your feedback. Please note Aspose.Pdf page origin is left bottom(0,0), so you need to to reset the article coordinates as following. Hopefully it will help you to resolve the issue.

Document document = new Document(myDir

  • “HindustanTime.pdf”);<o:p></o:p>

PageCollection coll = document.Pages;

Aspose.Pdf.Rectangle rect = document.Pages[1].Rect;

Aspose.Pdf.Rectangle pageRect = new Aspose.Pdf.Rectangle(20, 671, 693, 1125);

document.Pages[1].CropBox = pageRect;

MemoryStream ms = new MemoryStream();

document.Save(myDir+"A2.pdf");


Please feel free to contact us for any further assistance.

I have one more question
I assume following
llx = margin from left
lly = margin from bottom
urx = width of article
ury = height of article

can you tell me what is actually llx,lly,urx and ury

Thanks in advance

Hi Devinder,


Thanks for your feedback. Please note as stated above page origin in Aspose.Pdf is left bottom of page. So the coordinates would be as following.

llx(lower left x coordinate)=margin from left.
lly(lower left y coordinate)=margin from bottom(bottom of rectangle)
urx(upper right x coordinate)=width of article
ury(upper right y coordinate)=margin from bottom of upper boundary of article.

For example A4 size page dimensions are(8.672x11.6972) so its rectangle coordinates would be from left bottom of page as following.

llx=0
lly=0
urx=594.72
ury=841.68

Hopefully it would help you to understand the rectangle coordinates.
