short x, y;

unsigned short width, height;

short anglel, angle2; } XArc;

XChar2b

XChar2b specifies a character in a two-byte font A list of structures of this type is an argu ment to XDrawImageSt ringl 6, XDrawStringl 6, XDrawText 16, XQueryText-Extentsl6, XTextExtentsl6, and XTextWidthl6. The only two-byte font cur rently available is Kanji (Japanese).

typedef struct { /* normal 16 bit characters are two bytes */

unsigned char bytel;

unsigned char byte2; } XChar2b;

F.3.3 XCharStruct

XCharStruct describes the metrics of a single character in a font or the overall character istics of a font This structure is the type of several of members of XFontStruct and is used to return the overall characteristics of a string in XQueryTextExtents* and XTextExtents*.

typedef struct {

short Ibearing; /* origin to left edge of raster */

short rbearing; /* origin to right edge of raster */

short width; /* advance to next char's origin */

short ascent; /* baseline to top edge of raster */

short descent; /* baseline to bottom edge of raster *,

unsigned short attributes; /* per char flags (not predefined) */

} XCharStruct;

F.3.4 XCIassHint

XClassHint is used to set or get the XA_WM_CLASS_HINT property for an application's top-level window, as arguments toXSetClassHint or XGetClassHint.

typedef struct {

char *res_name;

char *res_class; } XClassHint;

F.3.5 XColor

XColor describes a single colorcell. This structure is used to specify and return the pixel value ...
