PdfMetamorphosisHtmlSettingBaseUrl Property

The part of document’s URL preceding its name. Default value: Empty.

Namespace: SautinSoft
Assembly: PdfMetamorphosis (in PdfMetamorphosis.dll) Version: 2024.12.19
Syntax
Copy
public string BaseUrl { get; set; }

Property Value

String
Remarks
URL assigned to a page to convert "relative URLs" into "absolute URLs" by the addition of a document name or trailing slash /.

It’s very important to set this property when converting HTML document in memory in order to determine where all relative URLs are pointing to and convert them to absolute.

For example, let's convert HTML string to a PDF file.

Assuming we've specified:

p.HtmlOptions.BaseUrl = @"d:\my webs";

Now when the component meets 'src="images/asterisk.jpg"' it will try to load an image from: "d:\my webs\images\asterisk.jpg"
