Example:
This opens the charter font at 12 points. The point size is automatically converted to the correct pixel size based on the resolution of the monitor.
void
XftTextExtents8 (Display *dpy,
XftFont *font,
FcChar8 *string,
int len,
XGlyphInfo *extents);
XftTextExtents8 computes the pixel extents of "string" when drawn with "font".
XftDraw *
XftDrawCreate (Display *dpy,
Drawable drawable,
Visual *visual,
Colormap colormap);
XtDrawCreate creates a structure that can be used to render text and rectangles to the screen.
void
XftDrawString8 (XftDraw *d,
XftColor *color,
XftFont *font,
int x,
int y,
FcChar8 *string,
int len);
XftDrawString8 draws "string" using "font" in "color" at "x, y".
void
XftDrawRect (XftDraw *d,
XftColor *color,
int x,
int y,
unsigned int width,
unsigned int height);
XftDrawRect fills a solid rectangle in the specified color.
Bool
XftColorAllocName (Display *dpy,
Visual *visual,
Colormap cmap,
char *name,
XftColor *result);
XftColorAllocName allocates a XftColor structure. It asks the X server to allocate a pixel and return the associated RGB values wich are used to construct an XRenderColor . This requires a round trip (bad).
Bool
XftColorAllocValue (Display *dpy,
Visual *visual,
Colormap cmap,
XRenderColor *color,
XftColor *result);
For TrueColor visuals, XftColorAllocValue computes the nearest supported ARGB value and the associated pixel value and stores them in the result. No round trip is required. For non-TrueColor visuals, XftColorAllocValue asks the X server to allocate the specified color and stores the resulting pixel and ARGB values into result.
void
XftColorFree (Display *dpy,
Visual *visual,
Colormap cmap,
XftColor *color);
XftColorFree frees a color when it is no longer in use.
