Trait Implementations

impl Default for Code39Writer

fn default() -> Code39Writer

Returns the “default value” for a type.

impl OneDimensionalCodeWriter for Code39Writer

fn encode_oned(&self, contents: &str) -> Result<Vec<bool>>

Encode the contents to boolean array expression of one-dimensional barcode. Start code and end code should be included in result, and side margins should not be included.

fn getSupportedWriteFormats(&self) -> Option<Vec<BarcodeFormat>>

fn encode_oned_with_hints( &self, contents: &str, _hints: &EncodingHintDictionary ) -> Result<Vec<bool>>

Can be overwritten if the encode requires to read the hints map. Otherwise it defaults to {@code encode}. @param contents barcode contents to encode @param hints encoding hints @return a {@code boolean[]} of horizontal pixels (false = white, true = black)

fn renderRXingResult( code: &[bool], width: i32, height: i32, sidesMargin: u32 ) -> Result<BitMatrix>

@return a byte array of horizontal pixels (0 = white, 1 = black)

fn checkNumeric(contents: &str) -> Result<()>

@param contents string to check for numeric characters @throws IllegalArgumentException if input contains characters other than digits 0-9.

fn appendPattern<T: TryInto<usize> + Copy>( target: &mut [bool], pos: usize, pattern: &[T], startColor: bool ) -> u32

@param target encode black/white pattern into this array @param pos position to start encoding at in {@code target} @param pattern lengths of black/white runs to encode @param startColor starting color - false for white, true for black @return the number of elements added to target.

fn getDefaultMargin(&self) -> u32

impl Writer for Code39Writer

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

Encode a barcode using the default settings.

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

@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
