>From the API docs I read this:

FT_LOAD_TARGET_LIGHT:
Use hinting for FT_RENDER_MODE_LIGHT.

FT_RENDER_MODE_LIGHT:
This is similar to FT_RENDER_MODE_NORMAL -- you have to use
FT_LOAD_TARGET_LIGHT in calls to FT_Load_Glyph to get any effect since
the rendering process no longer influences the positioning of glyph
outlines. The resulting glyph shapes are more similar to the original,
while being a bit more fuzzy (`better shapes' instead of `better
contrast', so to say.

What I make up of this: FT_RENDER_MODE_LIGHT has become deprecated, and
specifying it is exactly the same as specifying FT_RENDER_MODE_NORMAL.

I should only use FT_LOAD_TARGET_LIGHT in FT_Load_Glyph().

So:

error = FT_Load_Char( face, text[n], FT_LOAD_DEFAULT |
FT_LOAD_TARGET_LIGHT)
...
error = FT_Glyph_To_Bitmap( &glyph, FT_RENDER_MODE_NORMAL, 0, 1 );  

---


If my assumption is correct, I would suggest moving the explanation to
the FT_LOAD_TARGET_LIGHT flag docs, and have FT_RENDER_MODE_LIGHT refer
to FT_LOAD_TARGET_LIGHT.

Furthermore, on the web API docs, I noticed FT_LOAD_TARGET_LIGHT is not
in the FT_LOAD_XXX list that sits before their descriptions.


Thanks, best regards,

Leon.
