XFontSetExtents(3X11) XFontSetExtents(3X11) NAME XFontSetExtents - XFontSetExtents structure DESCRIPTION The XFontSetExtents structure contains: typedef struct { XRectangle max_ink_extent; /* over all drawable characters */ XRectangle max_logical_extent; /* over all drawable characters */ } XFontSetEx- tents; The XRectangle structures used to return font set metrics are the usual Xlib screen-oriented rectangles 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 Xmb- TextExtents(3X11) and XwcTextExtents(3X11) for detailed semantics. The max_logical_extent member gives the maximum extent, over all draw- able characters, of the rectangles that specify minimum spacing to other graphical features, relative to a constant origin. Other graphi- cal features drawn by the client, for example, a border surrounding the text, should not intersect this rectangle. The max_logical_extent mem- ber should be used to compute minimum interline spacing and the minimum area that must be allowed in a text field to draw a given number of ar- bitrary 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.
