XmbTextExtents(3X11) XmbTextExtents(3X11) NAME XmbTextExtents, XwcTextExtents - compute text extents SYNOPSIS int XmbTextExtents(font_set, string, num_bytes, overall_ink_return, overall_logical_return) XFontSet font_set; char *string; int num_bytes; XRectangle *overall_ink_return; XRectangle *overall_logical_return; int XwcTextExtents(font_set, string, num_wchars, overall_ink_return, overall_logical_return) XFontSet font_set; wchar_t *string; int num_wchars; XRectangle *overall_ink_return; XRectangle *overall_logical_return; ARGUMENTS Specifies the font set. Specifies the number of bytes in the string argument. Specifies the number of characters in the string argument. Returns the overall ink dimensions. Returns the overall logical dimen- sions. Specifies the character string. DESCRIPTION The XmbTextExtents and XwcTextExtents functions set the components of the specified overall_ink_return and overall_logical_return arguments to the overall bounding box of the string's image and a logical bound- ing box for spacing purposes, respectively. They return the value re- turned by XmbTextEscapement or XwcTextEscapement. These metrics are relative to the drawing origin of the string, using the fonts loaded for the specified font set. If the overall_ink_return argument is non-NULL, it is set to the bound- ing box of the string's character ink. The overall_ink_return for a nondescending, horizontally drawn Latin character is conventionally en- tirely above the baseline; that is, overall_ink_return.height <= -over- all_ink_return.y. The overall_ink_return for a nonkerned character is entirely at, and to the right of, the origin; that is, overall_ink_re- turn.x >= 0. A character consisting of a single pixel at the origin would set overall_ink_return fields y = 0, x = 0, width = 1, and height = 1. If the overall_logical_return argument is non-NULL, it is set to the bounding box that provides minimum spacing to other graphical features for the string. Other graphical features, for example, a border sur- rounding the text, should not intersect this rectangle. When the XFontSet has missing charsets, metrics for each unavailable character are taken from the default string returned by XCreateFontSet so that the metrics represent the text as it will actually be drawn. The behavior for an invalid codepoint is undefined. SEE ALSO XmbTextEscapement(3X11), XmbTextPerCharExtents(3X11) Xlib -- C Language X Interface XmbTextExtents(3X11)
