XFontSetExtents(3)                             XLIB FUNCTIONS                             XFontSetExtents(3)



NAME
       XFontSetExtents - XFontSetExtents structure

STRUCTURES
       The XFontSetExtents structure contains:

       typedef struct {
            XRectangle max_ink_extent;/* over all drawable characters */
            XRectangle max_logical_extent;/* over all drawable characters */
       } XFontSetExtents;

       The XRectangle structures used to return font set metrics are the usual Xlib screen-oriented rectan-gles rectangles
       gles with x, y giving the upper left corner, and width and height always positive.

       The max_ink_extent member gives the maximum extent, over all drawable characters, of the rectangles
       that bound the character glyph image drawn in the foreground color, relative to a constant origin.
       See XmbTextExtents and XwcTextExtents for detailed semantics.

       The max_logical_extent member gives the maximum extent, over all drawable characters, of the rectan-gles rectangles
       gles that specify minimum spacing to other graphical features, relative to a constant origin.  Other
       graphical features drawn by the client, for example, a border surrounding the text, should not inter-sect intersect
       sect this rectangle.  The max_logical_extent member should be used to compute minimum interline spac-ing spacing
       ing and the minimum area that must be allowed in a text field to draw a given number of arbitrary
       characters.

       Due to context-dependent rendering, appending a given character to a string may change the string's
       extent by an amount other than that character's individual extent.
