One more word.
My idea is that the most you can cache and save in an editable way, the most you can tune in scribus font handling. The very deep idea is to have a cache for OpenType-like features that you can edit and then give these features to type1 fonts for example. Brief, it's an idea, who knows what can it gives ?

I had similar ideas, making fonts customizable in many ways.

About your patch: maybe that code should go into scface.{h,cpp}, so that non-FT fonts could also profit from it, should we implement those. In my view saving the font customisation data should not be automatic, but explicit.

In the long run a customized font should allow:

* customized kerning, including kern classes
* pre-scaling
* merging fonts, eg. symbol fonts or Type1 expert fonts to get better Unicode coverage
* customize encoding
* customizing leading, space width and other params
* storing default font substitutions
* store preferences for embedding/subsetting
* grouping of font families and optical sizes
* store licence information
* group fonts into sets

For that I planned to extend the current fontcache into a fontmanagement database. What do you think?

administrator   ~0013671

Would this feature also cover "faked" spaces, that are missing in the original font, e.g. an automatically or manually created thin space, that could be stored for use in Scribus?

avox

2006-11-30 13:37

administrator   ~0013672

I plan to implement those spaces independently of font customisation. I already started with ZWSPACE and ZWNBSPACE; also NBSPACE and NBHYPHEN and SHYPHEN do not need to be present in a font.

I think only normal width spaces need to be configurable, the others are fixed proportions of an EM, no?

What do you think of emulating dashes by scaling hyphen horizontally?

>>plan to implement those spaces independently of font customisation.

Wow, thanks a lot!

>>I think only normal width spaces need to be configurable, the others are fixed proportions of an EM, no?

Not exactly, but other measurements seem to disappear due to anglo-american predominance in computer typography; see 3400

>>What do you think of emulating dashes by scaling hyphen horizontally?

Why not? If they have the right size, it doesn't matter on what original dimensions they're based. It's only important to have the right proportions at hand.

Actually, Avox is right. There are "convention spaces" an EM is a full em width and an en is half an em wide. There are many more, proportions are available in the "Adding typographic spaces to fonts with FontForge" tutorial I wrote for the wiki.

3400 makes no sense, an EM is now the width of an "M", and neither is an EN the width of an "N".

Still, I wouldn't hard-code them, just because if you make it possible to customize some, you should rather do it for all.

By the way just make sure that the space sizes are saved with the file too. If people have set different thicknesses for the same space name, that's likely to cause trouble somewhere.

No, that's bad typography practice, don't do it.

Short: I think that if Scribus needs to store font informations, and in this, a fontmanagement database is necessary, users needs to be presented a ,if not simple (font programs are not), at least clear font management _file_ format. Yes, I think that's offer to store all what scribus knows about fonts into files is the best way to save work for scribus' developers (because the font customization tool is there, a text editor) and can quickly give users full power over their fonts. Very short: Thinking of an efficient text-based afm-but-more-powerfull-like could be of some interest.

>* customized kerning, including kern classes
Storing kern classes would be far more efficient than what I did.

>* merging fonts, eg. symbol fonts or Type1 expert fonts to get better Unicode coverage
It gives me the idea of a new definition of metafont ! Could we imagine font paths as a root and glyphs as leaves and a way to abstract on these basis. If I want to merge two glyphs, as a user I put in a file something like
glyph://MinionPro/Bold/emdash
glyph://GillSans/Reg/Thin/Ucircumflex
and why not
gsub://MinionPro/Reg/liga
and
Ok, I stop it |

New step:
After a long and deep think about what you stated, I stoped tweaking {sc,ft}_face and began to work on Vface, a virtual face.
I think i'll can test into it all suggestions you made except "advanced typographic features" as we can find un OT or sil fonts since layout() runs in position by position. If you can send a word for pre-processing before including it in the --- more than 1000 lines loop :-) --- actual layout sub, it could be processed in a harbuzz buffer and come back with features applied, but maybe I didn't understood well how the whole thing works.
For the Vface, if you have time to expose which methods are required and which are for XXface internal use, it would save me a bunch of time.

nb:
It's not the place where my work is yet but, my idea is to build a type 3 font for embedding in pdf. What do tou think of the idea, and if it's not that bad one, will be somebody to help ?

I got the following list of required methods to implement in a face class with grep|sed|sort|uniq , kind of "brute force":-)
Does it match all ?

glyphKerning
glyphOrigin
glyphOutline

Hi Pierre,

I recently converted ScFace to the "private implementation" pattern, aka "handle".

This means that ScFace is a handle class and all interesting stuff and the subclassing is done in ScFaceData:


    ScFaceData <------------ ScFace
        ^
        |
  ------+-----------------
  | | |
FtFace HarfBuzzFace VFace
  |
FtFace_ttf


This means that all methods in ScFaceData mut be implemented.
The following have reasonable defaults:
* glyphWidth
* glyphOrigin
* glyphOutline

Those three rely on loadGlyph() to fill the caches. loadFace() must fill
all other member variables of ScFaceData.
For VFace you could forward most methods to the contained faces, even
glyphWidth/Origin/Outline. Especially the last would avoid double caching.

EmbedFont() should just return false for now since that will not work if a VFace is containing several faces. Same for RawData().

layout() is waiting to be renamed to legacy_layout and to be replaced by a new layout() function (codename NLS). A lot of that stuff is in flux, so it would be best if you concentrate on the stuff you can implement within ScFace.

For an overview of the new system, checkout http://rants.scribus.net/2006/10/31/boston-text-layout-summit/
Pending changes include:
* replacement of the StoryText class
* rewrite of DrawObj_Item, layoutGlyphs(), drawGlyphs()
* switch between layout() and legacy_layout() depending on a user flag

Advanced features will be controlled by an attribute list in CharStyle,
eg. [+smallcap,-stdlig,+oldstyle]. Some of those which can be implemented
on a char-by-char basis might find their way into legacy_layout(). I also
plan to implement a few emulating features, eg. fake_smallcaps, fake_oldstyle
etc.

Other font management functionality will go into ScFonts, which also needs a full rewrite.

/* ALL THIS IS DUMMY IMPLEMENTATION

I'm far to be an xml designer or however it has to be called, so I present the xml/ufr format quite simply (no schema inside).

<font name="foo" path="bar">
	<glyph codepoint="XXXX" />

... to say that you can have as many font elements as you want and other ones will come asap !

I upload a first shot of "Virtual face class". At least it compiles :) I'll see tomorrow if it works. I didn't upload the patch of scfont I made to load virtual fonts, so don't hope to try.
Virtual font file (.ufr( user font ressource)) should look like that :
<ufr>
   <info name="family"> family </info>
   etc.
   <font name="foo" path="bar.ufr">
      <glyph codepoint="XXXX" />
      etc.
   </font>
   <font name="anotherfont" path="/ano/ther/font.ufr>
      <glyph codepoint="YYYY" />
   </font>
   etc.
   <pairkern left="XXXX" right="YYYY" value="nnn" />
   etc.
<ufr>
Of course codepoint is unicode. Later glyph would be describe as
<glyph sourcecodepoint="XXXX" destcodepoint="XYXY" />

I get some bad headache,and the first visual result. It's not very impressive but I put it here to givee an idea.

cool.
did you manually select outline style and large spacing?

reporter   ~0013887

Andreas, are you kidding me ?
Outline style and large spacing is the basis of my headache. For retrieving glyphs from fontfile, I made a large use of code present in FtFace. And I continue to wonder why when _you_ get width by " double ww = face->glyph->metrics.horiAdvance / m_uniEM; ", it seems to work, it was necessary for me ---just to get "displayable" glyph --- to hack that in "gmet.width = tmpface->glyph->metrics.horiAdvance / (uniEM * 10);". I also made large use of qDebug and saw that "tmpface->units_per_EM" returns 1000 for the two faces involved in the example, which seems quite normal, but "tmpface->glyph->metrics.horiAdvance" is about 30000 or so for each glyph. I guess I missed something somewhere and continue to read freetype.h (think i gonna print it to sleep with one day :-).
Second, I can't find what is in charge of drawing glyphs (though bt gives page_item calling VFace::glyphOutline) and just imitated the way you load outlines in m_glyphOutline (I mean with traceGlyph call to get FpointArray)and then return the outline via VFace::glyphOutline and... wait and see !
Ok. I have to leave now. But as you can imagine, I have very lot beaucoup muchos questions about font driving in Scribus.
nb: I put last version of Vface and try to make a diff of my changes in, mainly, ScFont.

vface-0.0.0.tar.gz is intended to work, must say, I hope it will work for you.
Now that it can display some glyphs, next step is to export them. And next next step is to provide more customizations.

PDF export still doesn't work, but printing seems to be ok. Next next step soon !

I upload a full featured ufr file. I'd like to know what do you think of that.
1/ Are features intesting ?
2/ Can you imagine to write such files for your own purpose or is it really too much complicated and need some{thing, gui} to help?
3/Ideas ?

I upload a new version of vface with a 1 in it because you can now export to pdf.
If someone could find time to test it, it would be good even if I know that it is not solid.

edit: This morning, I said on irc there was a problem with fileloader but I guess it was too soon in the morning. There is a "quick and dirty" workaround in the diff.

Come back.
Actually, I didn't gave up with vface. But before I continue in this way I would be interested in push a bit OTF in Scribus, because as far as I can see Harfbuzz is not ready and Scribus team prepares the QT4 switch. So, I just took libotf, made a simple c++ wrapper and tried it out. It's yet experimental and needs a big load of work but I got a result (see scribus-otf.png). For now, i experimented with GSUB table only because all can be done before _the big loop_. My idea to process GPOS is to set a context string at the beginning of _the big loop_ and the layout does not ask a char to the font but an index in the context string to the font.
I guess it's not crystal clear. Feel free to ask precisions.

Hm, it's pretty much decided that Scribus will use HarfBuzz in the future. The OTF table handling functions of HarfBuzz are already used in Qt and Pango, and there's some activity to include shaping code into HB.

Still, nice work. About the "Big Loop": have a look at PageItem::layoutGlyphs().
That's where Unicode is converted into glyph ids. It currently uses the GlyphLayout structure from sctextstruct.h, but should use a HarfBuzz buffer directly in the future.

IMHO, the "open type features handler" is not the most important. I mean, whatever it is, features take place between the font and the layout --- FreeType argues of that to not support it --- and you have to change the way you build your layout engine to take it in account. For example, I was relieved when I found PageItem::layoutGlyphs() as I thought I could avoid to write in _the big loop_ but when I qDebugged what is sent to PageItem::layoutGlyphs() it appeared that chstr is just one char long. So it's not suitable to process contextual stuff --- substitution or positionning.
I used libotf as a prototype because the wrapper was written for long time ;-) and really easier to use than Harfbuzz. Finally, my aim is just to point out the minimum requirements needed to handle OpenType fonts in Scribus, because I think it would be near the top of TODO list

 ScFace objects are quite small and can be handled like value objects. Reference
