如何为 PdfSharp 生成的 Pdf 提供自定义大小

Question

I was trying to generate a pdf from HTML which containing a table using PdfSharp and HTMLRenderer. The following shows the code.

            pdf = PdfGenerator.GeneratePdf(html, PageSize.A3);

            byte[] fileContents = null;
            using (MemoryStream stream = new MemoryStream())
            {
                pdf.Save(stream, true);
                fileContents = stream.ToArray();
                return new FileStreamResult(new MemoryStream(fileContents.ToArray()), "application/pdf");
            }

Is there any possibility for me to provide a custom size to the PDF and change the orientation of the page. I am using a memory stream to show the PDF directly on the browser display.

Answer 1

You can use the PdfGenerateConfig parameter of the GeneratePdf method to specify a custom page size using the ManualPageSize property.

Use the PageOrientation to get standard page sizes in landscape.

Code from comment:

var config = new PdfGenerateConfig();
config.PageOrientation = PageOrientation.Landscape;
config.ManualPageSize = new PdfSharp.Drawing.XSize(1080, 828);

pdf = PdfGenerator.GeneratePdf(html, config);

Answer 2

I just put this way:

var config = new PdfGenerateConfig()
{
    MarginBottom = 100,
    MarginLeft = 20,
    MarginRight = 20,
    MarginTop = 100,
    PageSize = PageSize.A4
};         

PdfDocument pdf = PdfGenerator.GeneratePdf(html, config); 

Answer 3

If I'm not mistaken, PageSize.A3 is not an enum but Rectangle value. So instead of passing predefined Rectangle you can provide your own, for example:

new Rectangle(1191, 842) // for album A3

new Rectangle(842, 595) // for album A4

and so on...
