[ft-devel] Glyph.bitmap.rows and width are zero

[arc]

Hi all:
I use an Unicode ttf file to render my chinese text.But I got a problem in some charcodes.

here is my code:

glyph_index = FT_Get_Char_Index( m_pkFT_ChtFace, charcode);
if (glyph_index == 0)
            return;

error = FT_Load_Glyph( m_pkFT_ChtFace,  glyph_index, FT_LOAD_DEFAULT );
if (error)
    return;

error = FT_Render_Glyph( m_pkFT_ChtFace->glyph, FT_RENDER_MODE_NORMAL );
if (error)
    return;

rows = m_pkFT_ChtFace->glyph.bitmap.rows;

width= m_pkFT_ChtFace->glyph.bitmap.width;

after FT_Render_Glyph() function (this function return error code 0) m_pkFT_ChtFace->glyph.bitmap.rows and width are zero.
(1) Is that means my ttf file doesn't have this charcode 's bitmap ?
(2) If my ttf file doesn't have this charcode 's bitmap, Why FT_Render_Glyph() doesn't return an error code?

Thanks all
