DejaVu QPF is no longer officially supported
(Apr 21 2005)
Neverhless this is good news for two reasons. Firstly I was never good package maintainer and all QPF versions were late. And secondly - now DejaVu is officially included in Familiar (0.8.2) and Openzaurus (3.5.3), so it is very easy to get them. Type
ipkg list | grep dejavu
...and choose what sizes and faces do you want.
Thanks to all folks from DejaVu and OpenEmbedded for good work, give yourself some beer. :)
Information about QPF version of DejaVu
QPF fonts are used in QT/Embedded environments - Opie and Qtopia and maybe in other QT-based systems. These environments are run mostly on pocket devices such as Linux iPaq or Sharp Zaurus.
QPF fonts are bitmap fonts; that means they are not scalable. They are "rendered" from TTF in fixed dimensions specified in "rendering" process. Package dejavu-qpf-normal-version.tar.gz contains all DejaVu fonts in dimensions 8, 10 and 12 points, package dejavu-qpf-huge-version.tar.gz contains 14, 18 and 24 points large fonts. All fonts are in regular, bold, italic and bold-italic layout.
Devices running Opie/Qtopia are able to rotate display in four ways - portrait, landscape, upside down and landscape upside down. For each rotation you need a separate set of fonts. These packages contain fonts for all these rotations.
Semantics of file naming is quite easy. Example: "dejavusans_100_80i_t5.qpf" means that the name displayed in system will be "dejavusans", the number "100" means that the font is 10 points big (divide the number by 10). Next number and possibly a letter describes weight (50=regular, 80=bold, i=italic) - in our example bold-italic. "t5" means rotation - files without rotation are displayed portrait, "t5" files are rotated 90 degrees clockwise, "t15" means 180 degrees and "t10" is 270 degrees. And yes, the rotation is really little bit silly, one more time: nothing=0 degrees, t5=90, t15=180 and t10=270. In fact it is more complicated - on iPaq 3870 0 degrees means "landscape" (the landscape with thumb of your right hand on 5-way button) and 90 degrees means "portrait" (you need fonts without "t" and with "t5"). Other hardware platforms have different default rotation, just try.
To install fonts on your device, simply copy selected files into $QTDIR/lib/fonts. (This works for Opie, it may be different on other QT environments. If unsure, try to find other .qpf files.) No changes in "fontdir" file are necessary, in fact the file is required only for translating TTF or type1 fonts and can be safely deleted. After copying files optionally restart your Opie/Qtopia/whatever; is is not necessary, but just to be sure.
Hint: To save flash space, select only the fonts/sizes/rotations you really need. For example, you usually use only two rotations (portrait and landscape) and some sizes of fonts.
HOWTO translate TTF font into QPF
Difficult way: Compile makeqpf utility as described in http://www.ossh.com/zaurus/mirrors/docs.zaurus.com/ttf_conversion.shtml and translate fonts as described in page, but look into my fontdir file how to create your own. (!!!)
Easier way: Download http://moria.ionkov.net/zaurus/makeqpf/makeqpf-arm to your device, place TTF fonts in your font dir, create fontdir file (look in my one how) and run
cd your_font_dir ~/makeqpf-arm -A ~/makeqpf-arm -A -display Transformed:Rot90 ~/makeqpf-arm -A -display Transformed:Rot180 ~/makeqpf-arm -A -display Transformed:Rot270
Known issues
- opie-reader (up to version at least 1.1.6) does not display zcaron and scaron (it displays "z" and "s" instead). But this not a bug in dejavu-qpf. You can try Opie Text Editor, it displays all (or at least all czech :) DejaVu symbols perfectly. Opie Text Editor is utf-8 only, get some utf-8 file with non latin-1 symbols and open it. Good reader for Opie is JustReader.
- the most applications in present time Opie do not even try to support different encodings :(
Plans
Make .ipks. - done, search your pocket distribution. :)
Changes in 1.6
- fontdir file is more readable, thanks to http://opie.handhelds.org/cgi-bin/moin.cgi/CreateFontsForOpie
