How to crop a Pdf with printer/crop marks

The Example PDF is: PDF

Using Aspose.PDF for .NET, I'm trying to crop a PDF which has white spaces around the edges, and printer/crop marks. My first approach was to find out the dimensions of the Art box, media box, trim box, crop box; and try to figure out if any of these boxes didn't include the white space, so i could just crop that out and save as a new PDF.

However this PDF doesn't have the ArtBox/TrimBox correctly set. So i can't take this approach.

My Next though was to manually crop the PDF with respect to the printer/crop marks at the edges. However I'm unable to locate these elements inside the PDF using Aspose.

The below Aspose.Pdf for .NET example will crop your PDF and remove the printer marks.

Aspose.Pdf.Document document = new Aspose.Pdf.Document(dataDir + "bre25419_cover.pdf");
//Iterate through All Pages of a PDF Document
for (int i = 1; i <= document.Pages.Count; i++)
{
    Aspose.Pdf.Rectangle cropBox = document.Pages[i].CropBox;
    // Crop percentage of width and height
    double percentageX = 4.4f / 100 * cropBox.URX;
    double percentageY = 6.7f / 100 * cropBox.URY;
    // update page's crop box
    document.Pages[i].CropBox = new Aspose.Pdf.Rectangle(cropBox.LLX + percentageX, cropBox.LLY + percentageY, cropBox.URX - percentageX, cropBox.URY - percentageY);

    Console.WriteLine("cropBox.LLX: " + cropBox.LLX + "\ncropBox.LLY: " + cropBox.LLY + "\ncropBox.URX: " + cropBox.URX + "\ncropBox.URY: " + cropBox.URY);
}
// save document         
document.Save(dataDir + "bre25419_cover_Output.pdf");

In your specific case TrimBox == ArtBox == BleedBox == MediaBox [0 0 1642.5 1035]. There is no CropBox, so you can try to change MediaBox values,it used instead of CropBox by default (say with help of iText).

I have changed MediaBox a bit [72 72 1570.5 963]: enter image description here
