About FTLayout |
||||
============== |
||||
FTLayout is a layout engine stacked on FreeType2. Currently |
||||
TrueTypeGX/AAT is supported as a file format. OpenType is also |
||||
supported, but highly experimental. |
||||
|
||||
FTLayout provides an generic interface which is shared by a layout |
||||
engine(GXLayout) for TrueTypeGX/AAT and a layout engine(OTLayout)for |
||||
OpenType for glyph substitution, one of the text layout function. |
||||
|
||||
See "The TureType Font File" |
||||
(http://developer.apple.com/fonts/TTRefMan/RM06/Chap6.html) |
||||
about TrueTypeGX/AAT. |
||||
|
||||
About GXLayout |
||||
============== |
||||
GXLayout provides interface for mort, morx, lcar, format 0, 2 3 kern, |
||||
feat TrueTypeGX/AAT tables. |
||||
|
||||
We tested GXLayout against "Non-contextual glyph substitution" and |
||||
"Ligature substitution" in kochigx-substitute-20040218 |
||||
fonts. "Non-contextual glyph substitution" in |
||||
kochigx-substitute-20040218 fonts represents "vertical |
||||
substitution". "Ligature substitution" in kochigx-substitute-20040218 |
||||
fonts represents "Non-contextual glyph substitution". |
||||
|
||||
We tested GXLayout against "fi" ligature("Ligature substitution") in |
||||
MacOSX's dfonts. |
||||
|
||||
It seems that Pfaedit can generate TrueTypeGX/AAT font. However, we |
||||
have not tested GXLayout against fonts generated by Pfaedit yet. |
||||
|
||||
About OTLayout |
||||
============== |
||||
(Different from GXLayout)OTLayout is not written from scratch; it |
||||
is just applied existing implementation to FTLayout, a newly designed |
||||
interface. The existing implementation stands for: |
||||
|
||||
The code ported by the author of Pango to FreeType2 for using |
||||
the code in Pango from TrueTypeOpen code in FreeType1 |
||||
implemented by FreeType developers. |
||||
|
||||
What we have done is to make fit the existing implementation to |
||||
new FTLayout glyph substitution interface. As written above, OTLayout |
||||
in FTLayout is highly experimental. We have tested only punctuation |
||||
substitution in Japanese vertical writing. Currently OpenType/TrueType |
||||
is supported; OpenType/CFF is not supported. Hereafter in this |
||||
document we focus on GXLayout. |
||||
|
||||
Install |
||||
======= |
||||
You have not changed the install procedure. However we recommend to |
||||
give --prefix=/somewhere-different-from-/usr-or-/usr/local to |
||||
configure command if FreeType2 is already installed on your system. |
||||
e.g. --prefix=/opt |
||||
|
||||
We have taken care that we do not change the source/binary interfaces |
||||
of FreeType2. However FTLayout development is based on the FreeType |
||||
code of HEAD in FreeType2's CVS repository(as of Mon Feb 23 14:30:49 |
||||
2004). If source/binary interfaces are not compatible between in |
||||
FreeType2 on your system and that of HEAD, installing FreeType2 with |
||||
FTLayout into /usr/lib or /usr/local/lib will be trouble. Take care. |
||||
|
||||
Demo program |
||||
============ |
||||
fi and gxdemo are bundled as GXLayout demo programs. To build the demo |
||||
programs, type following command line in src/gxlayout after installing |
||||
FreeType2 with FTLayout: |
||||
|
||||
$ make -f demo.mk |
||||
|
||||
fi and gxdemo will be built. |
||||
|
||||
- fi command |
||||
With rules defined in a font file specified as the first argument |
||||
for fi, try to substitute "fi" glyph string; and print the result |
||||
to stdout. The default value defined in feat table is used as font |
||||
feature settings in substitution. If you want to try different |
||||
settings, gxdemo is suitable. |
||||
|
||||
Example: |
||||
|
||||
$ ./fi /Library/Fonts/Zapfino.dfont |
||||
------------------- |
||||
File: /Library/Fonts/Zapfino.dfont |
||||
Name: Zapfino |
||||
[IN]f: 536, i: 552 |
||||
[OUT]f: 1089, i: 65535<empty> |
||||
|
||||
This output stands for |
||||
- [IN] is input glyph string, |
||||
- [OUT] substituted glyph string, |
||||
- ([IN])the glyph id for `f' is 536, |
||||
- ([IN])the glyph id for `i' is 552, and |
||||
- ([OUT])as the result of substitution, we get single glyph which |
||||
is 1089. 536, 552 are ligature into 1089. |
||||
|
||||
Only FreeType2 with FTLayout and standard C library are used in |
||||
fi. |
||||
|
||||
- gxdemo |
||||
gxdemo is a tool to inspect tables in a TrueTypeGX/AAT font and |
||||
the behavior of GXLayout with GUI. |
||||
|
||||
Run gxdemo with a target TrueTypeGX/AAT font file from a terminal. |
||||
gxdemo's window has multiple tabs. |
||||
|
||||
In "Features" tab, you can change the feature settings. Pressing |
||||
"Reset" button and the settings are reset; setting are set to the |
||||
default values defined in feat table. With "Run" button, you can |
||||
try to substitute glyphs under the setting given in this "Features" |
||||
tab. Pressing "Run" button, "Input: " prompt is appeared in the |
||||
terminal. Give the glyph ids separated by space and type return key |
||||
at the end of input glyph ids. Then substituted glyph ids are |
||||
printed on the terminal. |
||||
|
||||
Example: |
||||
$ ./gxdemo ~/.fonts/kochigx-mincho-subst.ttf |
||||
Input: 200 19 20 300 |
||||
Substituted: 200 14571 65535<empty> 300 |
||||
|
||||
In "Glyph" tab, you can render a glyph by giving a glyph id. |
||||
|
||||
In "Dump" tab, you can dump the TrueTypeGX/AAT tables of the font |
||||
in pseudo XML format with pressing "Dump Font Tables" button. Also |
||||
with pressing "Dump Feature Request" button, you can dump the |
||||
current font feature settings in "Features" tab in a text format. |
||||
|
||||
Batch dump mode is also available. To dump mort and feat from a |
||||
terminal, type |
||||
|
||||
$ ./gxdemo --batch --table=mort:feat font.ttf |
||||
|
||||
We, FTLayout developers used |
||||
mlview(http://www.freespiders.org/projects/gmlview/) to browse |
||||
the XML formated dump datum. |
||||
|
||||
In "Trace" tab, you can set FreeType2's trace level. To examine |
||||
the process of glyph substitution, set "gxvm" and "gxchain" to 3. |
||||
|
||||
Different from fi, gxdemo uses gtk+ GUI toolkit. To build gxdemo, |
||||
following libraries are needed: |
||||
- glib-2.0 |
||||
- gtk+-2.0 |
||||
- libgnomecanvas-2.0 |
||||
- popt |
||||
At least Red Hat Linux 9 includes these libraries. |
||||
|
||||
Using FTLayout and GXLayout |
||||
=========================== |
||||
To do glyph substitution in your program, you have to use both |
||||
FTLayout interface(as generic interface) and GXLayout interface(as |
||||
concrete interface). The symbols in FTLayout have "FTL" as prefix. |
||||
The symbols in GXLayout have "GXL" as prefix. Symbols in FTLayout |
||||
are declared in include/freetype/ftlayout.h. Symbols in GXLayout |
||||
are declared in include/freetype/gxlayout.h. To include these header |
||||
files in your source file, you have to obey to the way of FreeType2; |
||||
you have to specify the header files in symbols: |
||||
|
||||
#include<ft2build.h> |
||||
... |
||||
#include FT_LAYOUT_H |
||||
#include FT_GXLAYOUT_H |
||||
|
||||
|
||||
The outlines of usage are: |
||||
|
||||
1. Create a face |
||||
This procedure is the same as before. |
||||
Create a `face' from the target font file after |
||||
initialize the library itself. |
||||
|
||||
2. Check the existence of substitution tables |
||||
You can check the existence of substitution table |
||||
in the target font by the logical AND operation between |
||||
face::face_flags and FT_FACE_FLAG_GLYPH_SUBSTITUTION. |
||||
|
||||
3. Check the type of layout engine |
||||
You can check whether the type of text layout engine |
||||
is GXLayout or OTLayout by invoking FTL_Query_EngineType. |
||||
Hereafter, we assume the engine type is GXLayout. |
||||
|
||||
4. Create a request |
||||
A `request' is needed in FTLayout to specify the |
||||
font feature settings in substitution. You can create more |
||||
than one requests against one face and specify the font |
||||
feature settings independently each of them; and activate |
||||
one of them. Invoke FTL_New_FeaturesRequest with a face to |
||||
create a requests. Invoke FTL_Done_FeaturesRequest to release a |
||||
request. |
||||
|
||||
5. Set the features and settings to the request |
||||
Concrete text layout engine(GXLayout)'s interface is used to |
||||
specify the font feature settings to a request. Following |
||||
functions are available to specify: |
||||
|
||||
- GXL_FeaturesRequest_Get_Feature returns a object(feature) |
||||
which represents Nth feature of a face. |
||||
|
||||
- GXL_FeaturesRequest_Get_Feature_Count returns the number of |
||||
features in a face. |
||||
|
||||
- GXL_Feature_Get_Setting returns a object(setting) which |
||||
requests Nth setting of a feature. |
||||
|
||||
- GXL_Feature_Get_Setting_Count returns the number of settings |
||||
in a feature. |
||||
|
||||
- GXL_Feature_Get_Name returns the name of given feature. |
||||
|
||||
- GXL_Setting_Get_State returns the state (enable or disable) |
||||
of given setting. |
||||
|
||||
- GXL_Setting_Get_Name returns the name of given setting. |
||||
|
||||
- GXL_Feature_Is_Setting_Exclusive returns whether given |
||||
setting is exclusive or not. |
||||
|
||||
These functions may be useful to construct GUI thorough which |
||||
application users can specify the font features settings. |
||||
"Features" tab of gxdemo may be good example to construct |
||||
GUI. |
||||
|
||||
The writing direction(vertical or horizontal) have to be |
||||
specified also in FTLayout level. Use |
||||
|
||||
FTL_Set_FeaturesRequest_Direction |
||||
|
||||
to specify. Whether you have to specify the direction in |
||||
GXLayout level or not depends on the target font file. |
||||
|
||||
6. Activate request |
||||
After setting a request by functions explained in 5., |
||||
You have to activate it. Use |
||||
|
||||
FTL_Activate_FeaturesRequest |
||||
|
||||
to activate a face. (Only one request is active for |
||||
a face at the same time.) |
||||
|
||||
7. Create input/output glyph array |
||||
FTL_New_Glyphs_Array is used to create a glyph array. |
||||
To substitute two glyph arrays are needed to store |
||||
input glyphs(input) and substituted result(output). |
||||
|
||||
About the input, you have to set the length and fill the array |
||||
with glyphs by your self. Use |
||||
|
||||
|
||||
FTL_Set_Glyphs_Array_Length |
||||
|
||||
to set the length of glyph array. Use `gid' field of glyph |
||||
array to fill the input glyphs. |
||||
|
||||
The length of output are automatically set by FTLayout. |
||||
|
||||
8. Substitute |
||||
Invoke |
||||
|
||||
FTL_Substitute_Glyphs |
||||
|
||||
with a face, input and output. |
||||
|
||||
Other than 5. are procedures are done in fi command. Therefore fi.c |
||||
may be good simple example to substitute glyphs. |
||||
|
||||
TODO |
||||
==== |
||||
- lazy table loading |
||||
- verification table data during loading not in |
||||
substitution time |
||||
- more detailing error codes and using them |

This directory contains new otlayout, opentype adapter for ftlayout |
||||
interface. Old otlayout is developed by FreeType developers and not |
||||
completed yet. This new otlayout is not completed but works. |
||||
|
||||
New otlayout supports only gsub table. the glyph substitution for |
||||
Japanese vertical layout is tested. gpos table is not supported. |
||||
The languages other than Japanese is not tested yet by us. |
||||
|
||||
The files in this directory are come from different places. |
||||
|
||||
1. FreeType1/TrueTypeOpen support (via pango) |
||||
2. Pango/opentype |
||||
3. developed at RedHat K.K. supported by Information Technology Promotion Agency, Japan. |
||||
4. glib/gunicode.h |
||||
5. freetype2/otlayout(old otlayout) directory in FreeType CVS repository |
||||
|
||||
The files in 5. are not used in new otlayout. |
||||
|
||||
This new otlayout is experimental in all aspects. |
||||
One of the biggest issue is that the symbols coming from 1. |
||||
and 2. have global scope; you cannot link gtk/pango library |
||||
with new otlayout. The symbol may be conflicted. |

`properties' (which is treated as a bit field) gives the glyph's |
