Verify if not obsolete Font management concept : Interesting documents about design of fonts implementations in : '.If it is possible to isolate it to just the file salatslayout.cxx provided in issue 23283 then I'm all for it.' Since a simple change there can easily break some use cases, several scripts, platforms and may have a bad performance impact, I'd rather not change anything in the core. '.Well, changing anything in the VCL text core is very hard, because it impacts basically everything text related in OOo.

A SalLayout object has the 'old pDXArray flavour' to keep the changes required by the rest of OOo minimal.' A SalLayout is just the abstracted combination of all these layout engines. Then learn ATSUI, Uniscribe, ICU's layout engine and Java's TextLayout really well. '.I think the best way is to deeply understand a SalLayout object is to get to know the very old VCL OutputDevice text related methods, and especially what the pDXArray parameter in them means. All text display, measurements, text breaking, glyph fallback etc. It corresponds to an ATSUTextLayout object on ATSUI. The SalLayout base class is the core of all VCL-text. vcl/*/gdi/ subdirectories might be interesting too. '.Everything is in VCL, especially the vcl/inc/sallayout.hxx header file is important. This patch is very old and worked for some simple situations.' '.I already started an ATSUI port long ago. ( see : ), so workaround or other hacks must be used.įirst contact with Herbert Duerr (hdu), about fonts : Note : Apple owns a Patent who does not allow us to use kerning and hinting as expected e.g. The pro to use X11 rendering is it is faster than use Apple font server, but the drawback is all featured improvement are not accessible, in particular kerning and hinting.

ttf part ot (most of) them, and uses X11 rendering to display them properly.
