For the moment, this module is very basic and the only fonts available is the helvetica 12 one. This module is currently broken under Windows.
void (*VisuGlTextFunc) (const gchar *text
,VisuGlTextSize size
);
A function that render iso8859-1 text at the current raster position.
Since: 3.7
gboolean
visu_gl_text_setFunc (VisuGlTextFunc func
);
Set the function to render text at the raster position.
Since: 3.7
gboolean
visu_gl_text_setFontSize (float size
);
Change the normal font size used by V_Sim (see VISU_GL_TEXT_NORMAL). The small font is scaled accordingly. This is working only with the FTGL backend.
Since: 3.7
void visu_gl_text_drawChars (const gchar *s
,VisuGlTextSize size
);
Draw the given string on the current raster position with default font.
void
visu_gl_text_initFontList ();
Initialise the font drawing with default font (depending on system).
It must be called before visu_gl_text_drawChars()
and not in a glNewList()
.
Can be called several times, fonts are initialized once only. Use
visu_gl_text_rebuildFontList()
to force to build a new font list.
void
visu_gl_text_rebuildFontList ();
Force to buid a new font list (for example new context has changed.
void
visu_gl_text_onNewContext ();
Set the flag for text list build to FALSE. It will force to rebuild
the text lists at next call of visu_gl_text_initFontList()
.
Since: 3.6
void visu_gl_text_putTextWithFTGL (const gchar *text
,VisuGlTextSize size
);
A VisuGlTextFunc routine using FTGL to render text with Pixmap
lists, see visu_gl_text_setFunc()
.
Since: 3.7
