======================================== LEGACY FONTS: CONVERSION FROM PSF TO BDF ======================================== The traditional font collection for Linux consolle was a big mess. There were many different fonts and nobody in the world knew the exact purpose of all of them. During the years new fonts were added, but old were almost newer removed. Some of the fonts shared common typeface, i.e. they were differently encoded but the common glyphs were equal. In total, however, there were too many different typefaces that generally differ one from another only a little. In order to reduce the total number of fonts, they were converted to BDF format. During the conversion of the fonts, only one BDF font was generated for a group of fonts that share common typeface. Console fonts that didn't have embedded Unicode table were simply ignored. The fonts LatArCyrHeb* were also ignored - partialy due to technical reasons and partialy because the other BDF fonts are better source for making Unicode console fonts. The resulting BDF fonts are named after the scheme legacyNNp.bdf, where NN is 8, 10, 12, 14, 16 or 19 (the number of scan lines of the font, i.e. the font matrix is 8xNN) and p is a, b, c, d, e,... and serves to ensure the uniqueness of the file names. The table at the end of this text, documents the correspondence between file names of the resulting BDF fonts and the names of the PSF fonts that were used to produce them. We see that some of the resulting BDF fonts were produced by only one source PSF font (for example only iso06.f08.psf was used to produce legacy8d.bdf) while for others it was possible to incorporate the glyphs from more than one PSF font (for example six PSF fonts were used to produce legacy16e.bdf). ================================================ LEGACY FONTS: BACK CONVERSION - FROM BDF TO PSF ================================================ Only one PSF font per combination of codeset-size is generated from the legacy fonts and is named after the scheme CODESET-vgaSIZE.psf. For example Greek-vga14.psf is the legacy font for Greek code set and size 14. The list of BDF fonts that is used to produce Greek-vga14.psf was determined as folows. First, see which one of the legacy BDF fonts can provide as many glyphs for Greek-vga14.psf as possible. This was legacy14g.bdf (produced from iso07.f14.psf). Then see which one of the other legacy BDF fonts provides as much glyphs for Greek-vga14.psf that legacy14g does not provide. And so on. The resulting lists are represented as Codeset-legacySIZE-BDFS targets in the Makefile. It is perfectly OK to handtune them. For example if one decides that the look of legacy16i.bdf is superior it is OK to list legacy16i.bdf as primary font for Lat15-vga16.psf even though legacy16c.bdf provides more glyphs. There is one exception to the previous paragraph: the wonderful font UNI_VGA of Dmitry Bolkhovityanov was always used as a primary font for VGA16 fontface. ==================================== THE SOURCES OF THE FONTS legacy*.bdf ==================================== legacy8a.bdf: cp857-8x8.psf iso01.f08.psf iso05.f08.psf iso07.f08.psf iso09.f08.psf legacy8b.bdf: Cyr_a8x8.psf koi8u_8x8.psf ruscii_8x8.psf legacy8c.bdf: iso02.f08.psf iso03.f08.psf iso04.f08.psf iso10.f08.psf legacy8d.bdf: iso06.f08.psf legacy8e.bdf: iso08.f08.psf legacy8f.bdf: lat0-08.psf lat9u-08.psf legacy8g.bdf: lat1-08.psf lat1u-08.psf lat9v-08.psf lat9w-08.psf legacy8i.bdf: lat4-08.psf lat4a-08.psf lat4u-08.psf legacy10a.bdf: lat4-10.psf lat4a-10.psf lat4u-10.psf legacy10b.bdf: lat0-10.psf lat9u-10.psf legacy10c.bdf: lat1-10.psf lat1u-10.psf lat9v-10.psf lat9w-10.psf legacy10d.bdf: lat2u-10.psf legacy12a.bdf: lat0-12.psf lat9u-12.psf legacy12b.bdf: lat1-12.psf lat1u-12.psf lat9v-12.psf lat9w-12.psf legacy12c.bdf: lat2u-12.psf legacy12d.bdf: lat4-12.psf lat4a-12.psf lat4u-12.psf legacy14a.bdf: cp857-8x14.psf iso01.f14.psf iso05.f14.psf iso09.f14.psf legacy14b.bdf: Cyr_a8x14.psf legacy14c.bdf: koi8u_8x14.psf legacy14d.bdf: ruscii_8x14.psf legacy14e.bdf: iso02.f14.psf iso03.f14.psf iso04.f14.psf iso10.f14.psf legacy14f.bdf: iso06.f14.psf legacy14g.bdf: iso07.f14.psf legacy14h.bdf: iso08.f14.psf legacy14i.bdf: lat0-14.psf lat9u-14.psf legacy14j.bdf: lat1-14.psf lat1u-14.psf lat9v-14.psf lat9w-14.psf legacy14k.bdf: lat2u-14.psf legacy14l.bdf: lat4-14.psf lat4a-14.psf lat4u-14.psf legacy16a.bdf: cp857-8x16.psf iso01.f16.psf iso05.f16.psf iso07.f16.psf iso09.f16.psf legacy16b.bdf: Cyr_a8x16.psf koi8u_8x16.psf ruscii_8x16.psf legacy16c.bdf: default8x16.psf lat0-sun16.psf lat2-sun16.psf legacy16d.bdf: viscii10-8x16.psf legacy16e.bdf: iso02.f16.psf iso02g.psf iso03.f16.psf iso03g.psf iso04.f16.psf iso10.f16.psf lat2u-16.psf legacy16f.bdf: iso06.f16.psf legacy16g.bdf: iso08.f16.psf legacy16h.bdf: iso14.f16.psf legacy16i.bdf: lat0-16.psf lat9u-16.psf legacy16j.bdf: lat1-16.psf lat1u-16.psf legacy16k.bdf: lat4-16.psf lat4a-16.psf lat4u-16.psf legacy16l.bdf: lat9v-16.psf lat9w-16.psf legacy16m.bdf: lat4-16+.psf lat4a-16+.psf lat4u-16+.psf legacy19a.bdf: lat4-19.psf lat4a-19.psf lat4u-19.psf Goha12.bdf: Goha-12.psf Goha14.bdf: Goha-14.psf Goha16.bdf: Goha-16.psf GohaClasic12.bdf: GohaClasic-12.psf GohaClasic14.bdf: GohaClasic-14.psf GohaClasic16.bdf: GohaClasic-16.psf
