public class STBTruetype
extends java.lang.Object
This library processes TrueType files:
Some important concepts to understand to use this library:
Characters are defined by unicode codepoints, e.g. 65 is uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is the hiragana for "ma".
A visual character shape (every codepoint is rendered as some glyph)
A font-specific integer ID representing a glyph
Glyph shapes are defined relative to a baseline, which is the bottom of uppercase characters. Characters extend both above and below the baseline.
As you draw text to the screen, you keep track of a "current point" which is the origin of each character. The current point's vertical position is the baseline. Even "baked fonts" use this model.
The vertical qualities of the font, used to vertically position and space the characters. See docs for GetFontVMetrics.
The preferred interface for specifying font sizes in stb_truetype is to specify how tall the font's vertical extent should be in pixels. If that sounds good enough, skip the next paragraph.
Most font APIs instead use "points", which are a common typographic measurement for describing font size, defined as 72 points per inch. stb_truetype provides a point API for compatibility. However, true "per inch" conventions don't make much sense on computer displays since different monitors have different number of pixels per inch. For example, Windows traditionally uses a convention that there are 96 pixels per inch, thus making 'inch' measurements have nothing to do with inches, and thus effectively defining a point to be 1.333 pixels. Additionally, the TrueType font data provides an explicit scale factor to scale a given font's glyphs to points, but the author has observed that this scale factor is often wrong for non-commercial fonts, thus making fonts scaled in points according to the TrueType spec incoherently sized in practice.
Select how high you want the font to be, in points or pixels. Call #()ScaleForPixelHeight or ScaleForMappingEmToPixels to compute a scale factor
SF that will be used by all other functions.
You need to select a y-coordinate that is the baseline of where your text will appear. Call GetFontBoundingBox to get the baseline-relative bounding
box for all characters. SF*-y0 will be the distance in pixels that the worst-case character could extend above the baseline, so if you want the
top edge of characters to appear at the top of the screen where y=0, then you would set the baseline to SF*-y0.
Set the current point where the first character will appear. The first character could extend left of the current point; this is font dependent. You can either choose a current point that is the leftmost point and hope, or add some padding, or check the bounding box or left-side-bearing of the first character to be displayed and set the current point based on that.
Compute the bounding box of the character. It will contain signed values relative to <current_point, baseline>. I.e. if it returns
x0,y0,x1,y1, then the character should be displayed in the rectangle from <current_point+SF*x0, baseline+SF*y0> to
<current_point+SF*x1,baseline+SF*y1).
Call GetGlyphHMetrics, and compute current_point += SF * advance.

Performance:
The system uses the raw data found in the .ttf file without changing it and without building auxiliary data structures. This is a bit inefficient on little-endian systems (the data is big-endian), but assuming you're caching the bitmaps or glyph shapes this shouldn't be a big deal.
It appears to be very hard to programmatically determine what font a given file is in a general way. I provide an API for this, but I don't recommend it.
Incomplete text-in-3d-api example, which draws quads properly aligned to be lossless:
unsigned char ttf_buffer[1<<20];
unsigned char temp_bitmap[512*512];
stbtt_bakedchar cdata[96]; // ASCII 32..126 is 95 glyphs
GLuint ftex;
void my_stbtt_initfont(void)
{
fread(ttf_buffer, 1, 1<<20, fopen("c:/windows/fonts/times.ttf", "rb"));
stbtt_BakeFontBitmap(ttf_buffer,0, 32.0, temp_bitmap,512,512, 32,96, cdata); // no guarantee this fits!
// can free ttf_buffer at this point
glGenTextures(1, &ftex);
glBindTexture(GL_TEXTURE_2D, ftex);
glTexImage2D(GL_TEXTURE_2D, 0, GL_ALPHA, 512,512, 0, GL_ALPHA, GL_UNSIGNED_BYTE, temp_bitmap);
// can free temp_bitmap at this point
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
}
void my_stbtt_print(float x, float y, char *text)
{
// assume orthographic projection with units = screen pixels, origin at top left
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, ftex);
glBegin(GL_QUADS);
while (*text) {
if (*text >= 32 && *text < 128) {
stbtt_aligned_quad q;
stbtt_GetBakedQuad(cdata, 512,512, *text-32, &x,&y,&q,1);//1=opengl & d3d10+,0=d3d9
glTexCoord2f(q.s0,q.t1); glVertex2f(q.x0,q.y0);
glTexCoord2f(q.s1,q.t1); glVertex2f(q.x1,q.y0);
glTexCoord2f(q.s1,q.t0); glVertex2f(q.x1,q.y1);
glTexCoord2f(q.s0,q.t0); glVertex2f(q.x0,q.y1);
}
++text;
}
glEnd();
}Complete program (this compiles): get a single bitmap, print as ASCII art:
char ttf_buffer[1<<25];
int main(int argc, char **argv)
{
stbtt_fontinfo font;
unsigned char *bitmap;
int w,h,i,j,c = (argc > 1 ? atoi(argv[1]) : 'a'), s = (argc > 2 ? atoi(argv[2]) : 20);
fread(ttf_buffer, 1, 1<<25, fopen(argc > 3 ? argv[3] : "c:/windows/fonts/arialbd.ttf", "rb"));
stbtt_InitFont(&font, ttf_buffer, stbtt_GetFontOffsetForIndex(ttf_buffer,0));
bitmap = stbtt_GetCodepointBitmap(&font, 0,stbtt_ScaleForPixelHeight(&font, s), c, &w, &h, 0,0);
for (j=0; j < h; ++j) {
for (i=0; i < w; ++i)
putchar(" .:ioVM@"[bitmap[j*w+i]>>5]);
putchar('\n');
}
return 0;
}Complete program: print "Hello World!" banner, with bugs:
char buffer[24<<20];
unsigned char screen[20][79];
int main(int arg, char **argv)
{
stbtt_fontinfo font;
int i,j,ascent,baseline,ch=0;
float scale, xpos=2; // leave a little padding in case the character extends left
char *text = "Heljo World!";
fread(buffer, 1, 1000000, fopen("c:/windows/fonts/arialbd.ttf", "rb"));
stbtt_InitFont(&font, buffer, 0);
scale = stbtt_ScaleForPixelHeight(&font, 15);
stbtt_GetFontVMetrics(&font, &ascent,0,0);
baseline = (int) (ascent*scale);
while (text[ch]) {
int advance,lsb,x0,y0,x1,y1;
float x_shift = xpos - (float) floor(xpos);
stbtt_GetCodepointHMetrics(&font, text[ch], &advance, &lsb);
stbtt_GetCodepointBitmapBoxSubpixel(&font, text[ch], scale,scale,x_shift,0, &x0,&y0,&x1,&y1);
stbtt_MakeCodepointBitmapSubpixel(&font, &screen[baseline + y0][(int) xpos + x0], x1-x0,y1-y0, 79, scale,scale,x_shift,0, text[ch]);
// note that this stomps the old data, so where character boxes overlap (e.g. 'lj') it's wrong
// because this API is really for baking character bitmaps into textures. if you want to render
// a sequence of characters, you really need to render each bitmap to a temp buffer, then
// "alpha blend" that into the working buffer
xpos += (advance * scale);
if (text[ch+1])
xpos += scale*stbtt_GetCodepointKernAdvance(&font, text[ch],text[ch+1]);
++ch;
}
for (j=0; j < 20; ++j) {
for (i=0; i < 78; ++i)
putchar(" .:ioVM@"[screen[j][i]>>5]);
putchar('\n');
}
return 0;
}You should really just solve this offline, keep your own tables of what font is what, and don't try to get it out of the .ttf file. That's because getting it out of the .ttf file is really hard, because the names in the file can appear in many possible encodings, in many possible languages, and e.g. if you need a case-insensitive comparison, the details of that depend on the encoding & language in a complex way (actually underspecified in truetype, but also gigantic).
But you can use the provided functions in two possible ways:
FindMatchingFont will use *case-sensitive* comparisons on unicode-encoded names to try to find the font you want; you can run this before
calling InitFontGetFontNameString lets you get any of the various strings from the file yourself and do your own comparisons on them. You have to have called

This function sets the amount of oversampling for all following calls to PackFontRange or PackFontRangesGatherRects for a given pack context. The
default (no oversampling) is achieved by h_oversample=1, v_oversample=1. The total number of pixels required is
h_oversample*v_oversample larger than the default; for example, 2x2 oversampling requires 4x the storage of 1x1. For best results, render
oversampled textures with bilinear filtering. Look at the readme in
stb/tests/oversample for information about oversampled fonts.
To use with PackFontRangesGather etc., you must set it before calls to PackFontRangesGatherRects.

PackFontRanges. If you want more control over the packing of multiple fonts, or
if you want to pack custom data into a font texture, take a look at the source of PackFontRanges and create a custom version using these functions,
e.g. call PackFontRangesGatherRects multiple times, building up a single array of rects, then call PackFontRangesPackRects once, then call
PackFontRangesRenderIntoRects repeatedly.

pixel_dist_scale & onedge_value are a scale & bias that allows you to make optimal use of the limited 0..255 for your
application, trading off precision and special effects. SDF values outside the range 0..255 are clamped to 0..255.
Example:
scale = stbtt_ScaleForPixelHeight(22)
padding = 5
onedge_value = 180
pixel_dist_scale = 180/5.0 = 36.0This will create an SDF bitmap in which the character is about 22 pixels high but the whole bitmap is about 22+5+5=32 pixels high. To produce a
filled shape, sample the SDF at each pixel and fill the pixel if the SDF value is greater than or equal to 180/255. (You'll actually want to
antialias, which is beyond the scope of this example.) Additionally, you can compute offset outlines (e.g. to stroke the character border inside &
outside, or only outside). For example, to fill outside the character up to 3 SDF pixels, you would compare against (180-36.0*3)/255 = 72/255.
The above choice of variables maps a range from 5 pixels outside the shape to 2 pixels inside the shape to 0..255; this is intended primarily
for apply outside effects only (the interior range is needed to allow proper antialiasing of the font at smaller sizes).
The function computes the SDF analytically at each SDF pixel, not by e.g. building a higher-res bitmap and approximating it. In theory the quality should be as high as possible for an SDF of this size & representation, but unclear if this is true in practice (perhaps building a higher-res bitmap and computing from that can allow drop-out prevention).
The algorithm has not been optimized at all, so expect it to be slow if computing lots of characters or very large sizes.
