Package: libcairo2
Version: 1.2.4-4
Severity: normal
Tags: patch
Cairo sometimes creates pdf files that contain invalid fonts, like the
following:
<< /Type /Font
/Subtype /TrueType
/BaseFont /DejaVuSans
/FirstChar 0
/LastChar 256
/FontDescriptor 171 0 R
/Widths [ ...(255 integers)... ]
>>
This font contains 256 characters, but /LastChar is incorrectly set to
256 instead of 255. acroread complains about incorrect /Widths in such
fonts (but shows file anyway).
There are several places in source code where number of characters is
passed as parameter for /LastChar, attached patch fixes this.
