This is a multi-part message in MIME format.
This is the fuction FTDemo_Update_Current_Flags() in ftcommon.c:
void
FTDemo_Update_Current_Flags( FTDemo_Handle* handle )
{
FT_UInt32 flags, target;
flags = FT_LOAD_DEFAULT; /* really 0 */
flags |= FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH;
if ( handle->autohint )
flags |= FT_LOAD_FORCE_AUTOHINT;
if ( !handle->use_sbits )
flags |= FT_LOAD_NO_BITMAP;
if ( handle->hinted )
{
target = 0;
if ( handle->antialias )
{
switch ( handle->lcd_mode )
{
case LCD_MODE_LIGHT:
target = FT_LOAD_TARGET_LIGHT;
break;
case LCD_MODE_RGB:
case LCD_MODE_BGR:
target = FT_LOAD_TARGET_LCD;
break;
case LCD_MODE_VRGB:
case LCD_MODE_VBGR:
target = FT_LOAD_TARGET_LCD_V;
break;
default:
target = FT_LOAD_TARGET_NORMAL;
}
}
else
target = FT_LOAD_TARGET_MONO;
flags |= target;
}
else
flags |= FT_LOAD_NO_HINTING;
handle->image_type.flags = flags;
handle->string_reload = 1;
}
It not update the handle->low_prec! How so?
Thanks.
Allan
