I'm using EO.Pdf 3.0.120.2 to render an html page to pdf with HtmlToPdf.ConvertUrl(). The page includes web fonts with a barcode font. The HtmlToPdf will not render the web font at first, then it will, then it won't, and then it will consistently. I have a complete sample I can submit, here's a summary: CSS: @font-face { font-family: 'barcode'; src: url('fonts/fre3of9x-webfont.eot'); src: url('fonts/fre3of9x-webfont.eot?#iefix') format('embedded-opentype'), url('fonts/fre3of9x-webfont.woff') format('woff'), url('fonts/fre3of9x-webfont.ttf') format('truetype'), url('fonts/fre3of9x-webfont.svg#fre3of9x') format('svg'); font-weight: normal; font-style: normal; } div.barcode { text-align: center; background-color: #ffffff; font-family: 'barcode'; font-size: 5em; } HTML: <div class="barcode"> *@Model.Ssn* </div>

Hi,
We do not support embedded font in CSS. You have to install the font on your system first, and they must be TrueType font.
Another method is to let your barcode library to render it as a plain image (such as .jpg). That way it won't depend on font at all.
Thanks!

If I embed the font on the server generating the report, but keep the @font-face declaration in the CSS so that a user browsing the page will see the appropriate font rendered, will this be okay?

Hi Donald,
Yes. You can do that. Just make sure you use the actual font name in the font file. With @font-face, you can name your font-family as anything you want; However once the font is installed on the server, you must use the actual font-family name that font is registered as.
Thanks!

Can you recommend some barcode library to help me do this,i am totally a greenhand in this field.Any suggestion will be appreciated. Thanks in advance.

Hi, We are not familiar with barcode library either. However the previous reply about embedded font is not longer true: we do support embedded font now (only TrueType font). Thanks!

I am having the same issue, sometimes the font is there, sometimes it is the backup font (or if I remove the backup font from the css, I get garbage instead). Could it be due to the slight delay while the embedded font is loaded? I've noticed that it can take a fraction of a second to display the custom font, if the PDF engine grabs the html in that time it'll get the backup font instead.
If this is correct, is there any way I can delay the PDF engine to ensure the page is loaded up fully?
For reference, I am embedding the font in this way:
@font-face {
font-family: Changeling;
src: url("changeling.ttf") format('truetype');
}
The font is installed on the server, is also in the directory with the webpages, and UAC is off.

I've used the MinLoadWaitTime to test this and it seems to be correct, however I've had to set it to 10 second delay to ensure the font loads up. There's probably something amiss with the webpage for it to be that bad. That said it is a fix for the intermittent font rendering issue.

We will look into this and see if we can find anything.
