Create a custom FTGL glyph object.
FIXME: maybe get rid of "base" and have advanceCallback etc. functions
- Parameters:
-
base | The base FTGLglyph* to subclass. |
data | A pointer to private data that will be passed to callbacks. |
renderCallback | A rendering callback function. |
destroyCallback | A callback function to be called upon destruction. |
- Returns:
- An FTGLglyph* object.
Destroy an FTGL glyph object.
- Parameters:
-
glyph | An FTGLglyph* object. |
float ftglGetGlyphAdvance |
( |
FTGLglyph * |
glyph | ) |
|
Return the advance for a glyph.
- Parameters:
-
glyph | An FTGLglyph* object. |
- Returns:
- The advance's X component.
void ftglGetGlyphBBox |

float |
bounds[6] |
|
) |
| |
Return the bounding box for a glyph.
- Parameters:
-
glyph | An FTGLglyph* object. |
bounds | An array of 6 float values where the bounding box's lower left near and upper right far 3D coordinates will be stored. |
FT_Error ftglGetGlyphError |
( |
FTGLglyph * |
glyph | ) |
|
Query a glyph for errors.
- Parameters:
-
glyph | An FTGLglyph* object. |
- Returns:

Render a glyph at the current pen position and compute the corresponding advance.
- Parameters:
-
glyph | An FTGLglyph* object. |
penx | The current pen's X position. |
peny | The current pen's Y position. |
renderMode | Render mode to display |
advancex | A pointer to an FTGL_DOUBLE where to write the advance's X component. |
advancey | A pointer to an FTGL_DOUBLE where to write the advance's Y component. |
