NAME
glutBitmapWidth - returns the width of a bitmap character, glutBitmapLength returns the length of a bitmap font string. SYNTAX
#include <GLUT/glut.h> int glutBitmapWidth(void *font, int character) int glutBitmapLength(void *font, const unsigned char *string) ARGUMENTS
font Bitmap font to use. For valid values, see the glutBitmapCharacter description. character Character to return width of (not confined to 8 bits). string Text string (8-bit characters), nul terminated. DESCRIPTION
glutBitmapWidth returns the width in pixels of a bitmap character in a supported bitmap font. While the width of characters in a font may vary (though fixed width fonts do not vary), the maximum height characteristics of a particular font are fixed. glutBitmapLength returns the length in pixels of a string (8-bit characters). This length is equivalent to summing all the widths returned by glutBitmapWidth for each character in the string. SEE ALSO

NAME
glutBitmapCharacter - renders a bitmap character using OpenGL. SYNTAX
#include <GLUT/glut.h> void glutBitmapCharacter(void *font, int character); ARGUMENTS
font Bitmap font to use. character Character to render (not confined to 8 bits). DESCRIPTION
Without using any display lists, glutBitmapCharacter renders the character in the named bitmap font. The available fonts are: GLUT_BITMAP_8_BY_13 A fixed width font with every character fitting in an 8 by 13 pixel rectangle. The exact bitmaps to be used is defined by the stan- dard X glyph bitmaps for the X font named: -misc-fixed-medium-r-normal--13-120-75-75-C-80-iso8859-1 GLUT_BITMAP_9_BY_15 A fixed width font with every character fitting in an 9 by 15 pixel rectangle. The exact bitmaps to be used is defined by the stan- dard X glyph bitmaps for the X font named: -misc-fixed-medium-r-normal--15-140-75-75-C-90-iso8859-1 GLUT_BITMAP_TIMES_ROMAN_10 A 10-point proportional spaced Times Roman font. The exact bitmaps to be used is defined by the standard X glyph bitmaps for the X font named: -adobe-times-medium-r-normal--10-100-75-75-p-54-iso8859-1 GLUT_BITMAP_TIMES_ROMAN_24 A 24-point proportional spaced Times Roman font. The exact bitmaps to be used is defined by the standard X glyph bitmaps for the X font named: -adobe-times-medium-r-normal--24-240-75-75-p-124-iso8859-1 GLUT_BITMAP_HELVETICA_10 A 10-point proportional spaced Helvetica font. The exact bitmaps to be used is defined by the standard X glyph bitmaps for the X font named: -adobe-helvetica-medium-r-normal--10-100-75-75-p-56-iso8859-1 GLUT_BITMAP_HELVETICA_12 A 12-point proportional spaced Helvetica font. The exact bitmaps to be used is defined by the standard X glyph bitmaps for the X font named: -adobe-helvetica-medium-r-normal--12-120-75-75-p-67-iso8859-1 GLUT_BITMAP_HELVETICA_18 A 18-point proportional spaced Helvetica font. The exact bitmaps to be used is defined by the standard X glyph bitmaps for the X font named: -adobe-helvetica-medium-r-normal--18-180-75-75-p-98-iso8859-1 Rendering a nonexistent character has no effect. glutBitmapCharacter automatically sets the OpenGL unpack pixel storage modes it needs appropriately and saves and restores the previous modes before returning. The generated call to glBitmap will adjust the current raster position based on the width of the character. EXAMPLE
Here is a routine that shows how to render a string of ASCII text with glutBitmapCharacter: void output(int x, int y, char *string) { int len, i; glRasterPos2f(x, y); len = (int) strlen(string); for (i = 0; i < len; i++) { glutBitmapCharacter(GLUT_BITMAP_HELVETICA_18, string[i]); } } SEE ALSO
