XmbTextPerCharExtents() XmbTextPerCharExtents() Name XmbTextPerCharExtents - obtain per-character measurements of an internationalized multi-byte text string. Synopsis Status XmbTextPerCharExtents(font_set, string, num_bytes, ink_array_return, logical_array_return, array_size, num_chars_return, over- all_ink_return, overall_logical_return) XFontSet font_set; char *string; int num_bytes; XRectangle *ink_array_return; XRectangle *logical_array_return; int array_size; int *num_chars_return; XRectangle *overall_ink_return; XRectangle *overall_logical_return; Arguments font_set Specifies the font set. string Specifies the character string. num_bytes Specifies the number of bytes in the string argument. ink_array_return Returns the ink dimensions for each character. logical_array_return Returns the logical dimensions for each character. array_size Specifies the size of ink_array_return and logical_array_return. Note that the caller must pass in arrays of this size. num_chars_return Returns the number characters in the string argument. overall_ink_return Returns the overall ink extents of the entire string. overall_logical_return Returns the overall logical extents of the entire string. Returns Zero on failure, non-zero on success. Availability Release 5 and later. Description XmbTextPerCharExtents() returns the text dimensions of each character of the specified text, using the fonts loaded for the specified font set. Each element of ink_array_return and logical_array_return is set to the corresponding character's drawn metrics, relative to the drawing origin of the string. The number of elements of ink_array_return and logical_array_return that have been set is returned in num_chars_return. Each element of ink_array_return is set to the bounding box of the corresponding character's drawn foreground color. Each element of logical_array_return is set to the bounding box which provides minimum spacing to other graphical features for the corresponding character. Other graphical features should not intersect any of the logical_array_return rectangles. Note that an XRectangle represents the effective drawing dimensions of the character, regardless of the number of font glyphs that are used to draw the character, or the direction in which the character is drawn. If multiple characters map to a single character glyph, the dimensions of all the XRectangles of those characters are the same. When the XFontSet has missing charsets, metrics for each unavailable character are taken from the default string returned by XCreate- FontSet(), so that the metrics represent the text as it will actually be drawn. The behavior for an invalid codepoint is undefined. If the array_size is too small for the number of characters in the supplied text, the function returns zero and num_chars_return is set to the number of rectangles required. Otherwise, it returns a non-zero value. If the overall_ink_return or overall_logical_return argument is non-NULL, XmbTextPerCharExtents() returns the maximum extent of the string's metrics to overall_ink_return or overall_logical_return, as is done by XmbTextExtents(). Structures typedef struct { short x, y; unsigned short width, height; } XRectangle; See Also XmbTextEscapement(), XmbTextExtents(), XwcTextPerCharExtents().
