Description Tobias Leich 2010-03-21 04:41:17 UTC 
Hi, if I do:

TTF_SetFontHinting(font, TTF_HINTING_LIGHT); // TTF_HINTING_LIGHT == 1

then:

TTF_GetFontHinting(font):

returns 65536 instead of TTF_HINTING_LIGHT (1).

You do a translation is the Set~ function:

void TTF_SetFontHinting( TTF_Font* font, int hinting )
{
	if (hinting == TTF_HINTING_LIGHT)
		font->hinting = FT_LOAD_TARGET_LIGHT;
	else if (hinting == TTF_HINTING_MONO)
		font->hinting = FT_LOAD_TARGET_MONO;
	else if (hinting == TTF_HINTING_NONE)
		font->hinting = FT_LOAD_NO_HINTING;
	else
		font->hinting = 0;
	Flush_Cache( font );
}

But none in the Get~ function:

int TTF_GetFontHinting( const TTF_Font* font )
{
	return font->hinting;
}

The FT_~ constants are not 0..3 like the TTF_~ are (freetype/freetype.h):

#define FT_LOAD_TARGET_( x )   ( (FT_Int32)( (x) & 15 ) << 16 )

#define FT_LOAD_TARGET_NORMAL  FT_LOAD_TARGET_( FT_RENDER_MODE_NORMAL )
#define FT_LOAD_TARGET_LIGHT   FT_LOAD_TARGET_( FT_RENDER_MODE_LIGHT  )
#define FT_LOAD_TARGET_MONO    FT_LOAD_TARGET_( FT_RENDER_MODE_MONO   )
#define FT_LOAD_TARGET_LCD     FT_LOAD_TARGET_( FT_RENDER_MODE_LCD    )
#define FT_LOAD_TARGET_LCD_V   FT_LOAD_TARGET_( FT_RENDER_MODE_LCD_V  )

Cheers
