|

|
-
|
|
|
|
|
- \section intro Introduction
|
|
|
|
|
-
|
|
|
|
|
- Pango is the text rendering engine of GNOME 2.x. SDL_Pango connects the
|
|
|
|
|
- engine to SDL. In Windows, pre-built binary package (MSI and merge module)
|
|
|
|
|
- is provided.
|
|
|
|
|
-
|
|
|
|
|
- \subsection dist Distribution
|
|
|
|
|
-
|
|
|
|
|
- If you are a game software developer, you should know the difficulties of
|
|
|
|
|
- distribution. So I will start to introduce SDL_Pango from the viewpoint
|
|
|
|
|
- of distribution.
|
|
|
|
|
-
|
|
|
|
|
- In Un*x, SDL_Pango is hard to use as system-independent module, because
|
|
|
|
|
- it depends on fontconfig and Pango which are designed as system-singleton
|
|
|
|
|
- modules. If you use SDL_Pango, your software will require those modules
|
|
|
|
|
- installed to target system. If your software is shipped as shrink-wrap
|
|
|
|
|
- package, it may cause much problem on your support desk. You should
|
|
|
|
|
- carefully design your installation process.
|
|
|
|
|
-
|
|
|
|
|
- In Windows, SDL_Pango is distributed as "merge module" which contains
|
|
|
|
|
- fontconfig and Pango. Those binaries are modified as side-by-side components.
|
|
|
|
|
- You should use Windows Installer and merge the module
|
|
|
|
|
- on your MSI package. The merge module not only contains files, but also includes
|
|
|
|
|
- custom action which must be run at installation.
|
|
|
|
|
-
|
|
|
|
|
- \subsection api High-level API
|
|
|
|
|
-
|
|
|
|
|
- From the viewpoint of text rendering, the heart of SDL_Pango is high-level API.
|
|
|
|
|
- Other text rendering APIs, like DrawText() of Windows, font and text must be
|
|
|
|
|
- specified separately. In SDL_Pango, font specification is embedded in text like
|
|
|
|
|
- HTML:
|
|
|
|
|
-
|
|
|
|
|
- \code
|
|
|
|
|
- <span font_family="Courier New"><i>This is Courier New and italic.</i></span>
|
|
|
|
|
- \endcode
|
|
|
|
|
-
|
|
|
|
|
- Color, size, subscript/superscript, obliquing, weight, and other many features
|
|
|
|
|
- are also available in same way.
|
|
|
|
|
-
|
|
|
|
|
- \subsection i18n Internationalized Text
|
|
|
|
|
-
|
|
|
|
|
- Internationalized text is another key feature. Text is specified by UTF-8. RTL
|
|
|
|
|
- script (Arabic and Hebrew) and complicated rendering (Arabic, Indic and Thai) are
|
|
|
|
|
- supported. You can see it with GNOME 2.x.
|
|
|
|

- \section get Getting Started
|
|
|
|
|
-
|
|
|
|
|
- \subsection getlatest Get latest files
|
|
|
|
|
-
|
|
|
|
|
- Get latest files from http://sourceforge.net/projects/sdlpango/ .
|
|
|
|
|
-
|
|
|
|
|
- \subsection install Install Header and Library
|
|
|
|
|
-
|
|
|
|
|
- In Windows and VS2003, I strongly recommend you to install MSI package. It contains Pango
|
|
|
|
|
- and fontconfig binaries which are modified as side-by-side components. It is
|
|
|
|
|
- nearly impossible to build them. (I spent much time to build them...)
|
|
|
|
|
-
|
|
|
|
|
- In MinGW, I recommend you to use VS2003. Otherwise you may run into the maze of
|
|
|
|
|
- distribution. If you insist MinGW, you should use MinGW binary archive.
|
|
|
|
|
-
|
|
|
|
|
- In Un*x, installation consists of:
|
|
|
|
|
-
|
|
|
|
|
- \code
|
|
|
|
|
- ./configure
|
|
|
|
|
- make
|
|
|
|
|
- make install
|
|
|
|
|
- \endcode
|
|
|
|
|
-
|
|
|
|
|
- \subsection inc Includes
|
|
|
|
|
-
|
|
|
|
|
- To use SDL_Pango functions in a C/C++ source code file, you must use the SDL_Pango.h
|
|
|
|
|
- include file:
|
|
|
|
|
-
|
|
|
|
|
- \code
|
|
|
|
|
- #include "SDL_Pango.h"
|
|
|
|
|
- \endcode
|
|
|
|
|
-
|
|
|
|
|
- In Windows, SDL_Pango.h is installed on \c \%ProgramFiles\%\\SDL_Pango \c Development\\include
|
|
|
|
|
- (usually \c C:\\Program \c Files\\SDL_Pango \c Development\\include). You should add this
|
|
|
|
|
- directory to include path.
|
|
|
|
|
-
|
|
|
|
|
- \subsection comp Compiling
|
|
|
|
|
-
|
|
|
|
|
- In Un*x, to link with SDL_Pango you should use sdl-config to get the required SDL
|
|
|
|
|
- compilation options. After that, compiling with SDL_Pango is quite easy.
|
|
|
|
|
-
|
|
|
|
|
- Note: Some systems may not have the SDL_Pango library and include file in the same
|
|
|
|
|
- place as the SDL library and includes are located, in that case you will need to
|
|
|
|
|
- add more -I and -L paths to these command lines.
|
|
|
|
|
-
|
|
|
|
|
- Simple Example for compiling an object file:
|
|
|
|
|
-
|
|
|
|
|
- \code
|
|
|
|
|
- cc -c `sdl-config --cflags` mysource.c
|
|
|
|
|
- \endcode
|
|
|
|
|
-
|
|
|
|
|
- Simple Example for linking an object file:
|
|
|
|
|
-
|
|
|
|
|
- \code
|
|
|
|
|
- cc -o myprogram mysource.o `sdl-config --libs` -lSDL_Pango
|
|
|
|
|
- \endcode
|
|
|
|
|
-
|
|
|
|
|
- Now myprogram is ready to run.
|
|
|
|
|
-
|
|
|
|
|
- You can see a sample of autoconfiscation in 'test' directory.
|
|
|
|
|
-
|
|
|
|
|
- In Windows, MSI package installs many dlls to \c \%ProgramFiles\%\\SDL_Pango \c Development\\import_lib.
|
|
|
|
|
- To link with SDL_Pango you should use SDL_Pango.lib.
|
|
|
|
|
-
|
|
|
|
|
- SDL_Pango.dll depends on many dlls and other many files. Those dlls are installed on
|
|
|
|
|
- \c \%ProgramFiles\%\\SDL_Pango \c Development\\bin. MSI package adds the directory to PATH environment
|
|
|
|
|
- variable.

|
|
|
|
|
-
|
|
|
|
|
- \subsection font Font Handling
|
|
|
|
|
-
|
|
|
|
|
- In Un*x, font handling depends on fontconfig of your system.
|
|
|
|
|
-
|
|
|
|
|
- In Windows, local.conf of fontconfig is placed on \c \%ProgramFiles\%\\SDL_Pango \c Development\\etc\\fonts.
|
|
|
|
|
- You should know about fontconfig's font cache mechanism.
|
|
|
|
|
-
|
|
|
|
|
- \subsection example Step-by-step Example
|
|
|
|
|
-
|
|
|
|
|
- The operation of SDL_Pango is done via context.
|
|
|
|
|
-
|
|
|
|
|
- \code
|
|
|
|
|
- SDLPango_Context *context = SDLPango_CreateContext();
|
|
|
|
|
- \endcode
|
|
|
|
|
-
|
|
|
|
|
- Specify default colors and minimum surface size.
|
|
|
|
|
-
|
|
|
|
|
- \code
|
|
|
|
|
- SDLPango_SetDefaultColor(context, MATRIX_TRANSPARENT_BACK_WHITE_LETTER);
|
|
|
|
|
- SDLPango_SetMinimumSize(context, 640, 0);
|
|
|
|
|
- \endcode
|
|
|
|
|
-
|
|
|
|
|
- Set markup text.
|
|
|
|
|
-
|
|
|
|
|
- \code
|
|
|
|
|
- SDLPango_SetMarkup(context, "This is <i>markup</i> text.", -1);
|
|
|
|
|
- \endcode
|
|
|
|
|
-
|
|
|
|
|
- Now you can get the size of surface.
|
|
|
|
|
-
|
|
|
|
|
- \code
|
|
|
|
|
- int w = SDLPango_GetLayoutWidth(context);
|
|
|
|
|
- int h = SDLPango_GetLayoutHeight(context);
|
|
|
|
|
- \endcode
|
|
|
|
|
-
|
|
|
|
|
- Create surface to draw.
|
|
|
|
|
-
|
|
|
|
|
- \code
|

- In Windows, font files must be installed on apprication folder (usually
|
|
|
|
|
- \c C:\\Program \c Files\\[Manufacturer]\\[ProductName]). The property of
|
|
|
|
|
- apprication folder must be \c TARGETDIR (this is default setting of VS2003).
|
|
|
|
|
- SDL.dll also must be installed on apprication folder. Add SDL_Pango.msm to
|
|
|
|
|
- your MSI package.

|
|
|
+ \section intro Introduction
|
|
|
|
|
+
|
|
|
|
|
+ Pango is the text rendering engine of GNOME 2.x. SDL_Pango connects the
|
|
|
|
|
+ engine to SDL. In Windows, pre-built binary package (MSI and merge module)
|
|
|
|
|
+ is provided.
|
|
|
|
|
+
|
|
|
|
|
+ \subsection dist Distribution
|
|
|
|
|
+
|
|
|
|
|
+ If you are a game software developer, you should know the difficulties of
|
|
|
|
|
+ distribution. So I will start to introduce SDL_Pango from the viewpoint
|
|
|
|
|
+ of distribution.
|
|
|
|
|
+
|
|
|
|
|
+ In Un*x, SDL_Pango is hard to use as system-independent module, because
|
|
|
|
|
+ it depends on fontconfig and Pango which are designed as system-singleton
|
|
|
|
|
+ modules. If you use SDL_Pango, your software will require those modules
|
|
|
|
|
+ installed to target system. If your software is shipped as shrink-wrap
|
|
|
|
|
+ package, it may cause much problem on your support desk. You should
|
|
|
|
|
+ carefully design your installation process.
|
|
|
|
|
+
|
|
|
|
|
+ In Windows, SDL_Pango is distributed as "merge module" which contains
|
|
|
|
|
+ fontconfig and Pango. Those binaries are modified as side-by-side components.
|
|
|
|
|
+ You should use Windows Installer and merge the module
|
|
|
|
|
+ on your MSI package. The merge module not only contains files, but also includes
|
|
|
|
|
+ custom action which must be run at installation.
|
|
|
|
|
+
|
|
|
|
|
+ \subsection api High-level API
|
|
|
|
|
+
|
|
|
|
|
+ From the viewpoint of text rendering, the heart of SDL_Pango is high-level API.
|
|
|
|
|
+ Other text rendering APIs, like DrawText() of Windows, font and text must be
|
|
|
|
|
+ specified separately. In SDL_Pango, font specification is embedded in text like
|
|
|
|
|
+ HTML:
|
|
|
|
|
+
|
|
|
|
|
+ \code
|
|
|
|
|
+ <span font_family="Courier New"><i>This is Courier New and italic.</i></span>
|
|
|
|
|
+ \endcode
|
|
|
|
|
+
|
|
|
|
|
+ Color, size, subscript/superscript, obliquing, weight, and other many features
|
|
|
|
|
+ are also available in same way.
|
|
|
|
|
+
|
|
|
|
|
+ \subsection i18n Internationalized Text
|
|
|
|
|
+
|
|
|
|
|
+ Internationalized text is another key feature. Text is specified by UTF-8. RTL
|
|
|
|
|
+ script (Arabic and Hebrew) and complicated rendering (Arabic, Indic and Thai) are
|
|
|
|
|
+ supported. You can see it with GNOME 2.x.
|
|

|
+ \section get Getting Started
|
|
|
|
|
+
|
|
|
|
|
+ \subsection getlatest Get latest files
|
|
|
|
|
+
|
|
|
|
|
+ Get latest files from http://sourceforge.net/projects/sdlpango/ .
|
|
|
|
|
+
|
|
|
|
|
+ \subsection install Install Header and Library
|
|
|
|
|
+
|
|
|
|
|
+ In Windows and VS2003, I strongly recommend you to install MSI package. It contains Pango
|
|
|
|
|
+ and fontconfig binaries which are modified as side-by-side components. It is
|
|
|
|
|
+ nearly impossible to build them. (I spent much time to build them...)
|
|
|
|
|
+
|
|
|
|
|
+ In MinGW, I recommend you to use VS2003. Otherwise you may run into the maze of
|
|
|
|
|
+ distribution. If you insist MinGW, you should use MinGW binary archive.
|
|
|
|
|
+
|
|
|
|
|
+ In Un*x, installation consists of:
|
|
|
|
|
+
|
|
|
|
|
+ \code
|
|
|
|
|
+ ./configure
|
|
|
|
|
+ make
|
|
|
|
|
+ make install
|
|
|
|
|
+ \endcode
|
|
|
|
|
+
|
|
|
|
|
+ \subsection inc Includes
|
|
|
|
|
+
|
|
|
|
|
+ To use SDL_Pango functions in a C/C++ source code file, you must use the SDL_Pango.h
|
|
|
|
|
+ include file:
|
|
|
|
|
+
|
|
|
|
|
+ \code
|
|
|
|
|
+ #include "SDL_Pango.h"
|
|
|
|
|
+ \endcode
|
|
|
|
|
+
|
|
|
|
|
+ In Windows, SDL_Pango.h is installed on \c \%ProgramFiles\%\\SDL_Pango \c Development\\include
|
|
|
|
|
+ (usually \c C:\\Program \c Files\\SDL_Pango \c Development\\include). You should add this
|
|
|
|
|
+ directory to include path.
|
|
|
|
|
+
|
|
|
|
|
+ \subsection comp Compiling
|
|
|
|
|
+
|
|
|
|
|
+ In Un*x, to link with SDL_Pango you should use sdl-config to get the required SDL
|
|
|
|
|
+ compilation options. After that, compiling with SDL_Pango is quite easy.
|
|
|
|
|
+
|
|
|
|
|
+ Note: Some systems may not have the SDL_Pango library and include file in the same
|
|
|
|
|
+ place as the SDL library and includes are located, in that case you will need to
|
|
|
|
|
+ add more -I and -L paths to these command lines.
|
|
|
|
|
+
|
|
|
|
|
+ Simple Example for compiling an object file:
|
|
|
|
|
+
|
|
|
|
|
+ \code
|
|
|
|
|
+ cc -c `sdl-config --cflags` mysource.c
|
|
|
|
|
+ \endcode
|
|
|
|
|
+
|
|
|
|
|
+ Simple Example for linking an object file:
|
|
|
|
|
+
|
|
|
|
|
+ \code
|
|
|
|
|
+ cc -o myprogram mysource.o `sdl-config --libs` -lSDL_Pango
|
|
|
|
|
+ \endcode
|
|
|
|
|
+
|
|
|
|
|
+ Now myprogram is ready to run.
|
|
|
|
|
+
|
|
|
|
|
+ You can see a sample of autoconfiscation in 'test' directory.
|
|
|
|
|
+
|
|
|
|
|
+ In Windows, MSI package installs many dlls to \c \%ProgramFiles\%\\SDL_Pango \c Development\\import_lib.
|
|
|
|
|
+ To link with SDL_Pango you should use SDL_Pango.lib.
|
|
|
|
|
+
|
|
|
|
|
+ SDL_Pango.dll depends on many dlls and other many files. Those dlls are installed on
|
|
|
|
|
+ \c \%ProgramFiles\%\\SDL_Pango \c Development\\bin. MSI package adds the directory to PATH environment
|
|
|
|
|
+ variable.

|
|
|
|
|
+ \subsection font Font Handling
|
|
|
|
|
+
|
|
|
|
|
+ In Un*x, font handling depends on fontconfig of your system.
|
|
|
|
|
+
|
|
|
|
|
+ In Windows, local.conf of fontconfig is placed on \c \%ProgramFiles\%\\SDL_Pango \c Development\\etc\\fonts.
|
|
|
|
|
+ You should know about fontconfig's font cache mechanism.
|
|
|
|
|
+
|
|
|
|
|
+ \subsection example Step-by-step Example
|
|
|
|
|
+
|
|
|
|
|
+ The operation of SDL_Pango is done via context.
|
|
|
|
|
+
|
|
|
|
|
+ \code
|
|
|
|
|
+ SDLPango_Context *context = SDLPango_CreateContext();
|
|
|
|
|
+ \endcode
|
|
|
|
|
+
|
|
|
|
|
+ Specify default colors and minimum surface size.
|
|
|
|
|
+
|
|
|
|
|
+ \code
|
|
|
|
|
+ SDLPango_SetDefaultColor(context, MATRIX_TRANSPARENT_BACK_WHITE_LETTER);
|
|
|
|
|
+ SDLPango_SetMinimumSize(context, 640, 0);
|
|
|
|
|
+ \endcode
|
|
|
|
|
+
|
|
|
|
|
+ Set markup text.
|
|
|
|
|
+
|
|
|
|
|
+ \code
|
|
|
|
|
+ SDLPango_SetMarkup(context, "This is <i>markup</i> text.", -1);
|
|
|
|
|
+ \endcode
|
|
|
|
|
+
|
|
|
|
|
+ Now you can get the size of surface.
|
|
|
|
|
+
|
|
|
|
|
+ \code
|
|
|
|
|
+ int w = SDLPango_GetLayoutWidth(context);
|
|
|
|
|
+ int h = SDLPango_GetLayoutHeight(context);
|
|
|
|
|
+ \endcode
|
|
|
|
|
+
|
|
|
|
|
+ Create surface to draw.
|
|
|
|
|
+
|
|
|
|
|
+ \code
|
|
|
|
|
+ int margin_x = 10;
|
|
|
|
|
+ int margin_y = 10;
|
|
|
|
|
+ SDL_Surface *surface = SDL_CreateRGBSurface(SDL_SWSURFACE,
|
|
|
|
|
+ w + margin_x * 2, h + margin_y * 2,
|
|
|
|
|
+ 32, (Uint32)(255 << (8 * 3)), (Uint32)(255 << (8 * 2)),
|
|
|
|
|
+ (Uint32)(255 << (8 * 1)), 255);
|
|
|
|
|
+ \endcode
|
|
|
|
|
+
|
|
|
|
|
+ And draw on it.
|
|
|
|
|
+
|
|
|
|
|
+ \code
|
|
|
|
|
+ SDLPango_Draw(context, surface, margin_x, margin_y);
|
|
|
|
|
+ \endcode
|
|
|
|
|
+
|
|
|
|
|
+ You must free the surface by yourself.
|
|
|
|
|
+
|
|
|
|
|
+ \code
|
|
|
|
|
+ SDL_FreeSurface(surface);
|
|
|
|
|
+ \endcode
|
|
|
|
|
+
|
|
|
|
|
+ Free context.
|
|
|
|
|
+
|
|
|
|
|
+ \code
|
|
|
|
|
+ SDLPango_FreeContext(context);
|
|
|
|
|
+ \endcode
|
|
|
|
|
+
|
|
|
|
|
+ You can see actual code in \c test/testbench.cpp.
|
|
|
|
|
+
|
|
|
|
|
+ \subsection pack Packaging
|
|
|
|
|
+
|
|
|
|
|
+ In Un*x, do it yourself.
|
|
|
|
|
+
|
|
|
|
|
+ In Windows, font files must be installed on apprication folder (usually
|
|
|
|
|
+ \c C:\\Program \c Files\\[Manufacturer]\\[ProductName]). The property of
|
|
|
|
|
+ apprication folder must be \c TARGETDIR (this is default setting of VS2003).
|
|
|
|
|
+ SDL.dll also must be installed on apprication folder. Add SDL_Pango.msm to
|
|
|
|
|
+ your MSI package.
