FreeType is written in C. It is designed to be small, efficient, and highly customizable while capable of producing high-quality output (glyph images) of most vector and bitmap font formats for digital typography. FreeType is a freely available and portable software library to render fonts.
CHANGES BETWEEN 2.4.10 and 2.4.11 I. IMPORTANT BUG FIXES - Some vulnerabilities in the BDF implementation have been fixed. Users of this font format should upgrade. II. IMPORTANT CHANGES - Subpixel hinting support has been contributed by Infinality, based on Greg Hitchcock's whitepaper at http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx Originally, it was a separate patch available from http://www.infinality.net/blog/ and which has been integrated. Note that ClearType support is not completely implemented! In particular, full support for the options `compatible_widths', `symmetrical_smoothing, and `bgr' (via the GETINFO bytecode instruction) is missing. Activation of subpixel hinting support can be controlled with the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option; it is switched off by default. This feature is still experimental; we welcome test reports! - Support for OpenType collections (OTC) has been added. - Pure CFF fonts within an SFNT wrapper are now supported. III. MISCELLANEOUS - Minor rendering improvements to the auto-hinter. - `FT_GlyphSlot_Oblique' now uses a shear angle of 12°. - Experimental support to handle `property modules', for example to control the behaviour of the auto-hinter. The API consists of two new functions, `FT_Property_Set' and `FT_Property_Get'. The code is still subject to change and should not be used for production. - The `ftdiff' demo program now supports UTF-8 encoded input files for option `-f'. - Using keys `r' and `R', you can now adjust the stroker radius in the `ftview' demo program. - Other, minor fixes and improvements.
