Cheers, Brian. Both types of fonts are fully usable and embedded into the PDF (i.e. the PDF is "selfcontained"). But only glyf-type fonts are subsetted, in other words: for CFF-type fonts the resulting PDF is not as small as it could be. For most fonts the size difference is probably in the lower 10 kB range.

I just added some fontconfig handling, so I consider my job done. - Fabian signature.asc Description: This is a digitally signed message part

Ok, I've finally managed to push last weekend's work into bzr, for the upcoming V1.0.6. This means: CFF-flavoured OTFs are now supported, but without subsetting, i.e. full embedding is done (while glyf-type TTFs are properly subsetted). I've done some cleanup/rework of the fontembed internals and fixed some bugs, that came along my way; The fontconfig selection in texttopdf now accepts both TTF and OTF fonts; I also did some minor improvements. Due to the rather large amount of touched code, new bugs might have crept in -- please report.

Hi Tobias, first, thanks for your fine work in libfontembed!

Or could this wait a few weeks? I don't think there are any strict time constraints. It is just that we are going to switch to format-independent package names for fonts in Debian and thus need to decide for one font format or the other - we are not going to ship a font in more than one format anymore unless strictly necessary. One of the reasons that might keep us from switching the freefonts package to OTF format is that it still is the prefered font for the texttopdf filter and that it currently needs this font in TTF format. - Fabian -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

I don't have the code ready to subset CFF-flavoured OTFs (but did some initial work some time ago [not under version control]). I will look into how we can at least provide full embedding for CFF. As I need metrics information from the font for texttopdf, this does require me to read at least some of the CFF formatted data -- which will need some work/time. My plan definitely is to support CFF eventually, as stated in the README of my so-called libfontembed. Are there any time constraints, like ASAP? Or could this wait a few weeks?

There are not really time constraints. For Ubuntu Precise 12.04 cups-filters 1.0.5 with texttopdf being fully fontconfig-based is enough. Precise comes with suitable TTF fonts. Currently, the change is more thought for upstream to be prepared for the first distros which drop TTF fonts.

Currently, the change is more thought for upstream to be prepared for the first distros which drop TTF fonts. Ok. I've looked a bit more into it now; the metrics are actually available in the usual form (hmtx-table). The only issue seems to be whether to only support PDF 1.6 (native OTF-CFF support), or also earlier versions, starting with PDF 1.2, which requires extraction of the CFF chunk (haven't looked at the details yet). Actually we currently claim PDF 1.3, but I'm not so sure, that I don't already use PDF1.6. features (libfontembed is called with EMB_DEST_PDF16 ...). I think that at least basic (non-subsetting) CFF support can/should be available and is easy enough to provide. At least PDF =1.6 support seems achievable in a reasonably short timeframe. Everything else can be added when there is an actual need.
