Please help me to load true type font file, using assembly. or anyway

Thanks

TrueType font files do not contain pixel matrices. Instead, the character
outlines are described using lines and curves. It's almost a mini computer
language.
The easy way to get pixels is to use the Win32 TextOut API into a bitmap.
If you aren't running in Windows, there are a couple of good open souorce
TrueType font renderers available, but they are rather complicated.

Interesting. I didn't realize that, clearly.
Of the 690 TrueType fonts on my machine, 4 contain EBLC and EBDT tables,
and none contain EBSC.

If you were to dig thru those 4 fonts, you would probably find that
the bitmaps are for very small point sizes (4,5,6,7 Pt or so). The
font descriptions don't work so well for complicated shapes in very
small sizes. The bitmaps provide a way around that.
Font sizes that small aren't much used for video display in any case.
For me, 8 Pt on a 1024x768 screen on a 17" monitor is just about too
small to read - I can read it, but it is a strain.
