  • WPDF and font issues with HTML

    We are using v4 of WPDF along with THtmlViewer for rendering PDF's that contain HTML. The method of rendering the HTML to the PDF is basically this:

    MetaFile := html.MakeMetaFile(0, html.Width, html.Width, html.Height);

    try

    Canvas.StretchDraw(Html.BoundsRect, MetaFile);

    finally

    MetaFile.Free;

    end;

    The problem we are seeing is that the rendering of the font is incorrect in two ways:

    1. The hyperlinks "appear" as hyperlinks (blue with underlines) but don't seem to be treated by the PDF reader as hyperlinks. If the displayed text of the <a> tag is also the link (e.g. href attribute value is the same as the content of the anchor element), then Adobe seems to be treated that text as a hyperlink on its own

    2. If the text contains a "w" then a space is appearing after the "w". This is causing an issue with #1 above if the URL contains a "w" - the link gets broken at the "w" and doesn't work properly.

    This is using Arial, 8pt. If I change to a different font such as Times New Roman, the problem goes away.

    Any suggestions?

    Thanks
