Class

PangoFcDecoder

since: 1.6

Description [src]

abstract class PangoFc.Decoder : GObject.Object
{
  /* No available fields */
}

PangoFcDecoder is a virtual base class that implementations will inherit from.

It’s the interface that is used to define a custom encoding for a font. These objects are created in your code from a function callback that was originally registered with pango_fc_font_map_add_decoder_find_func(). Pango requires information about the supported charset for a font as well as the individual character to glyph conversions. Pango gets that information via the #get_charset and #get_glyph callbacks into your object implementation.

Available since: 1.6
