RE: [ft] Drawing chinese text with FreeType on OpenGL

[Erik Möller]

Hi Stanley,

I think if you want some help from this list the easiest way is to write a
minimal app that loads a font, draws a glyph and then dumps it to a TGA. You
should be able to accomplish that in less than 100 lines of code and you
might even find that you work it out yourself while doing that little
exercise... if not I'll be happy to compile it and see if I can figure out
what's going wrong... not that I'm an expert on the topic or know a single
Chinese character for that matter :)

If you're not familiar with dumping to a TGA you can copy-paste some code
from this example: http://freetype.org/freetype2/docs/tutorial/example2.cpp


Cheers,

        //Load the Glyph for our character.
        //if(FT_Load_Glyph( face, FT_Get_Char_Index( face, ch ),
FT_LOAD_DEFAULT ))
        if(FT_Load_Glyph( face, FT_Get_Char_Index( face, 49896 ),
FT_LOAD_DEFAULT
))
                throw std::runtime_error("FT_Load_Glyph failed");

        //Move the face's glyph into a Glyph object.
    FT_Glyph glyph;
    if(FT_Get_Glyph( face->glyph, &glyph ))
                throw std::runtime_error("FT_Get_Glyph failed");

        //Convert the glyph to a bitmap.
        FT_Glyph_To_Bitmap( &glyph, ft_render_mode_normal, 0, 1 );
    FT_BitmapGlyph bitmap_glyph = (FT_BitmapGlyph)glyph;

        //This reference will make accessing the bitmap easier
        FT_Bitmap& bitmap=bitmap_glyph->bitmap;

everything was fine with the above code, but when i draw it on opengl
screen, all i see is a square/rectangle
