FT_RENDER_MODES

An enumeration type that lists the render modes supported by FreeType 2. Each mode corresponds to a specific type of scanline conversion performed on the outline.

For bitmap fonts and embedded bitmaps the ‘bitmap->pixel_mode’ field in the .. data:: FT_GlyphSlotRec structure gives the format of the returned bitmap.

All modes except FT_RENDER_MODE_MONO use 256 levels of opacity.

FT_RENDER_MODE_NORMAL

This is the default render mode; it corresponds to 8-bit anti-aliased bitmaps.

FT_RENDER_MODE_LIGHT

This is equivalent to FT_RENDER_MODE_NORMAL. It is only defined as a separate value because render modes are also used indirectly to define hinting algorithm selectors. See FT_LOAD_TARGET_XXX for details.

FT_RENDER_MODE_MONO

This mode corresponds to 1-bit bitmaps (with 2 levels of opacity).

FT_RENDER_MODE_LCD

This mode corresponds to horizontal RGB and BGR sub-pixel displays like LCD screens. It produces 8-bit bitmaps that are 3 times the width of the original glyph outline in pixels, and which use the FT_PIXEL_MODE_LCD mode.

FT_RENDER_MODE_LCD_V

This mode corresponds to vertical RGB and BGR sub-pixel displays (like PDA screens, rotated LCD displays, etc.). It produces 8-bit bitmaps that are 3 times the height of the original glyph outline in pixels and use the FT_PIXEL_MODE_LCD_V mode.
