Testing WeasyPrint
At the first glance WeasyPrint sounds promising, so why not try to see how well does it performs conversions from HTML to PDF?
The following PDF results from the conversion of the Beyond Social's article Eiland van Brienenoord onto a PDF using WeasyPrint.
The CSS style-sheet that gave origin the PDF is located at the end of this page
http://publicationstation.wdka.hro.nl/wiki/index.php/File:Web2print-BS07.pdf
Running
The standalone command weasyprint
can produce a PDF, simply with the instructions:
weasyprint EilandvanBrienenoord.html -s style.css ouput.pdf
Where:
EilandvanBrienenoord.html
- is the souce HTML file (could also be a URL)-s
- is the option for a CSS stylesheetouput.pdf
- the resulting PDF
@page
@page CSS rule that determines orientation and page size is successfully rendered in the PDF.
@page {
size: A5 portrait;
}
@page left @page right
Option for the left and right pages, such as the margin sizes, which have to alternate in order to produce a bound work, are correctly rendered.
@page:right {
margin-left: 3cm; /*inner margin*/
margin-right:1cm; /*outer margin*/
}
@page:left {
margin-right: 3cm; /*inner margin*/
margin-left:1cm; /*outer margin*/
}
@bottom
Weasy-print also applies consistently @bottom
rules, including page counting.
@bottom-right {
margin: 10pt 0 30pt 0;
border-top: .25pt solid #FF05F6;
content: "Testing WeasyPrint";
font-size: 6pt;
color: #00FFF2;
}
@bottom-center {
margin: 10pt 0 30pt 0;
content: counter(page);
font-size: 6pt;
}
CSS Custom Fonts
WeasyPrint does not support CSS's @font-face
rule.
Yet it can use fonts available in your system.
On Linux `fc-list` will give you a list of fonts installed in your system
List system installed fonts:
$ fc-list #show all the fonts available /usr/share/fonts/type1/texlive-fonts-recommended/pcrbo8a.pfb: Courier:style=Bold Italic /usr/share/fonts/type1/gsfonts/n019003l.pfb: Nimbus Sans L:style=Regular /usr/share/fonts/truetype/UbuntuMono-B.ttf: Ubuntu Mono:style=Bold
Add that font - Ubuntu Mono - in stayle sheet
body { font-size: 14pt;
color: blue;
font-family: "Ubuntu Mono";
}
