PangoFc.Decoder
Description: Reference for PangoFc.Decoder

### Class

# PangoFc.Decoder

#### 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.

#### Ancestors

- GObject

#### Instance methods

###### pango_fc_decoder_get_charset

Generates an `FcCharSet` of supported characters for the `fcfont` given.

###### pango_fc_decoder_get_glyph

Generates a `PangoGlyph` for the given Unicode point using the custom decoder.
