[ft] Bug in FT_Stroker ?

[Marcus Tillmanns]

Hi all,

I'm new to this list. Let me introduce myself quickly. I'm a programmer 
from germany, currently experimenting with freetype. I'm trying to use 
freetype in one of my opengl projects.

Here's my problem. I don't know if this is an error of mine or the 
freetype lib.

I tried the following: Render a stroke for the charachter '6' in the 
Windows standard font Verdana.ttf with FT_Set_Pixel_Sizes( ... , 14);

Shortly, this failed :)

I did the following:
* Load the font
* create the Stroker
*         FT_Stroker_Set( stroker, 30,
                       FT_STROKER_LINECAP_ROUND,
                       FT_STROKER_LINEJOIN_BEVEL,
                       0 );
* FT_Get_Glyph( m_ftFace->glyph, &glyph );
* FT_Glyph_Stroke( &glyph, stroker, true );

The call FT_Glyph_To_Bitmap( &glyph, FT_RENDER_MODE_NORMAL, 0, 1 )  
fails with error code 6

I traced a lot into the Library, and found that the Bounding box has a 
xMin of around -20000000.
This I traced down to an invalid value in outline->borders[1][41] where 
this value came from.

I don't know enough about the insides of freetype to narrow it down any 
more. It looked like the stroker has an invalid state at some point.

Could you give me any advice on how to handle this ? I'll try to use 
another LINECAP_XX for now.

Sincerly yours,
Marcus
