Required Methods§

source

fn encode( &self, contents: &str, format: &BarcodeFormat, width: i32, height: i32 ) -> Result<BitMatrix>

Encode a barcode using the default settings.

@param contents The contents to encode in the barcode @param format The barcode format to generate @param width The preferred width in pixels @param height The preferred height in pixels @return {@link BitMatrix} representing encoded barcode image @throws WriterException if contents cannot be encoded legally in a format

source

fn encode_with_hints( &self, contents: &str, format: &BarcodeFormat, width: i32, height: i32, hints: &EncodingHintDictionary ) -> Result<BitMatrix>

@param contents The contents to encode in the barcode @param format The barcode format to generate @param width The preferred width in pixels @param height The preferred height in pixels @param hints Additional parameters to supply to the encoder @return {@link BitMatrix} representing encoded barcode image @throws WriterException if contents cannot be encoded legally in a format
