I am experiencing an issue where the font sizing for rendered PDFs is larger in production. Everything looks great on the PDF generated in development.
Here is the rendering from development:

This is making it very difficult for me to format my document for the production server in development. Can you please take a look?
HTML Version: http://www.hearingtracker.com/tickets/170
PDF Download: http://www.hearingtracker.com/tickets/170.pdf
Here is my controller action:
def show
@ticket = Ticket.find(params[:id])
respond_to do |format|
format.html { render :layout => false }
format.pdf do
render :pdf => "HearingTrackerTicket",
:layout => false,
:dpi => '300'
end
end
end
Here is pdf.css.scss
.pdf-body {
background-color: white;

font-size: 12pt;
line-height: 20.5pt;
.underline {
border-bottom: 1pt solid;

回答1:
wkhtmltopdf can (and will) use system fonts to render content through its headless wekbkit browser.
So your issue is really an issue of differing environments in development and production.
If you have some control over your server, you might try installing freetype and fontconfig packages to get extra fonts on your server, or serving your fonts in your stylesheets as OTF files like this:
# in application.css.erb
@font-face {
font-family: 'OpenSansRegular';
src: url('<%= font_url('OpenSans.otf') %>');
font-weight: normal;
font-style: normal;
}
and telling the stylesheet to use that:
body {
font-family: 'OpenSansRegular';
font-size: 13px;
}
If you don't have the font in OTF, here's a service to convert them.
