Decoder is the structure used to decode JBIG2 encoded byte streams.
type Decoder struct {
// contains filtered or unexported fields
}
func Decode(input []byte, parameters Parameters, globals *document.Globals) (*Decoder, error)
Decode prepares decoder for the jbig2 encoded 'input' data, with optional 'parameters' and optional Globally encoded data segments - 'globals'.
func (d *Decoder) DecodeNextPage() ([]byte, error)
DecodeNextPage decodes next jbig2 encoded page and returns decoded byte stream
func (d *Decoder) DecodePage(pageNumber int) ([]byte, error)
DecodePage decodes jbig2 encoded page for provided 'pageNumber' in the document.
func (d *Decoder) DecodePageImage(pageNumber int) (image.Image, error)
DecodePageImage decodes page with 'pageNumber' from the document and stores it's result within go image.Image.
func (d *Decoder) PageNumber() (int, error)
PageNumber returns
Parameters are the parameters used by the jbig2 decoder.
