Aspose Words, Trim and Bleed Boxes for PDF output

Using Aspose.Words, is there a way to set the PDF Trim Box and Bleed Box for output to a PDF File.

I have a one page book cover and I need to set the bleed box and trim box for output to a PDF file … This is an automated process and the printer demands them defined.


Unfortunately, Aspose.Words does not provide the requested feature. However, you can work with PDF document using Aspose.PDF. I am moving this forum thread to Aspose.PDF forum where you will be guided appropriately.

I just need to SET the Trim and Bleed box and I am having problems. Can you provide be a code snippet. I think it starts something like this.

Document doc = new Document();
Page page = doc.Pages[1];


We have devised below code snippet for your kind reference. It includes how the rectangular coordinates, lower left X, Y, upper right X and Y can be set as per your requirements.

//Load source document
Document doc = new Document(dataDir + "Test.pdf");

//get reference to the page of itereate through each page with foreach loop
//foreach (Page page in doc.Pages)
Page page = doc.Pages[1];

//Get height and width of existing page, if needed
PdfFileInfo info = new PdfFileInfo(doc);
float width = info.GetPageWidth(page.Number);
float height = info.GetPageHeight(page.Number);

page.BleedBox.LLX = 10;
page.BleedBox.LLY = 10;
page.BleedBox.URX = width - 10;
page.BleedBox.URY = height - 10;

page.TrimBox.URX = 100;

doc.Save(dataDir + "Bleedbox.pdf");

Thanks for the reply. I tried the code but the values are not saving. I am not sure what I am doing wrong. Art of Romance.pdf (1.7 MB)

I have the PDF I am working with. Do I have to set some other setting first?
