PDF render SyntaxHighlight

[AlucardleVash]

Hello,

I have a trouble when i want to generate a pdf from the example on mac os.
I have :
pdftk 2.02
phamtomjs 1.9.7

I clone the git repository and just change in phantom-slippy-to-pdf.js :
page.paperSize = { width: viewport.width * 1.5, height: viewport.height * 1.5 + 30 };
with :
page.paperSize = { width: viewport.width * 1.8, height: viewport.height * 1.8 + 30 };

But syntaxhighlight don't work.
You can see in the following pdf.
