A few areas of the CGAME were left uses the old -// fonts since the code is shared with standard Q3A. -// -// If you include this font rendering code in a commercial product you MUST include the -// following somewhere with your product, see www.freetype.org for specifics or changes. -// The Freetype code also uses some hinting techniques that MIGHT infringe on patents -// held by apple so be aware of that also. -// -// As of Q3A 1.25+ and Team Arena, we are shipping the game with the font rendering code -// disabled. This removes any potential patent issues and it keeps us from having to -// distribute an actual TrueTrype font which is 1. expensive to do and 2. seems to require -// an act of god to accomplish. -// -// What we did was pre-render the fonts using FreeType ( which is why we leave the FreeType -// credit in the credits ) and then saved off the glyph data and then hand touched up the -// font bitmaps so they scale a bit better in GL. -// -// There are limitations in the way fonts are saved and reloaded in that it is based on -// point size and not name. So if you pre-render Helvetica in 18 point and Impact in 18 point -// you will end up with a single 18 point data file and image set. Typically you will want to -// choose 3 sizes to best approximate the scaling you will be doing in the ui scripting system -// -// In the UI Scripting code, a scale of 1.0 is equal to a 48 point font. In Team Arena, we -// use three or four scales, most of them exactly equaling the specific rendered size. We -// rendered three sizes in Team Arena, 12, 16, and 20. -// -// To generate new font data you need to go through the following steps. -// 1. delete the fontImage_x_xx.tga files and fontImage_xx.dat files from the fonts path. -// 2. in a ui script, specificy a font, smallFont, and bigFont keyword with font name and -// point size. the original TrueType fonts must exist in fonts at this point. -// 3. run the game, you should see things normally. -// 4. Exit the game and there will be three dat files and at least three tga files. The -// tga's are in 256x256 pages so if it takes three images to render a 24 point font you -// will end up with fontImage_0_24.tga through fontImage_2_24.tga -// 5. You will need to flip the tga's in Photoshop as the tga output code writes them upside -// down. -// 6. In future runs of the game, the system looks for these images and data files when a s -// specific point sized font is rendered and loads them for use. -// 7. Because of the original beta nature of the FreeType code you will probably want to hand -// touch the font bitmaps. -// -// Currently a define in the project turns on or off the FreeType code which is currently -// defined out. To pre-render new fonts you need enable the define ( BUILD_FREETYPE ) and -// uncheck the exclude from build check box in the FreeType2 area of the Renderer project. - - -#include "tr_local.h" -#include "../qcommon/qcommon.h" - -#ifdef BUILD_FREETYPE -#include <ft2build.h> -#include <freetype/fterrors.h> -#include <freetype/ftsystem.h> -#include <freetype/ftimage.h> -#include <freetype/freetype.h> -#include <freetype/ftoutln.h> - -#define _FLOOR(x) ((x) & -64) -#define _CEIL(x) (((x)+63) & -64) -#define _TRUNC(x) ((x) >> 6) - -FT_Library ftLibrary = NULL; -#endif - -#define MAX_FONTS 6 -static int registeredFontCount = 0; -static fontInfo_t registeredFont[MAX_FONTS]; - -#ifdef BUILD_FREETYPE -void R_GetGlyphInfo(FT_GlyphSlot glyph, int *left, int *right, int *width, int *top, int *bottom, int *height, int *pitch) { - - *left = _FLOOR( glyph->metrics.horiBearingX ); - *right = _CEIL( glyph->metrics.horiBearingX + glyph->metrics.width ); - *width = _TRUNC(*right - *left); - - *top = _CEIL( glyph->metrics.horiBearingY ); - *bottom = _FLOOR( glyph->metrics.horiBearingY - glyph->metrics.height ); - *height = _TRUNC( *top - *bottom ); - *pitch = ( qtrue ?
