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. 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. +// 6. 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_common.h" +#include "../qcommon/qcommon.h" + +#ifdef BUILD_FREETYPE +#include +#include FT_ERRORS_H +#include FT_SYSTEM_H +#include FT_IMAGE_H +#include FT_FREETYPE_H +#include FT_OUTLINE_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 ?
