Struct image::codecs::tga::TgaEncoder

pub struct TgaEncoder<W: Write> {
    writer: W,
    use_rle: bool,
}

TGA encoder.

Fields

writer: W

use_rle: bool

Run-length encoding

Implementations

impl<W: Write> TgaEncoder<W>

pub fn new(w: W) -> TgaEncoder<W>

Create a new encoder that writes its output to w.

pub fn disable_rle(self) -> TgaEncoder<W>

Disables run-length encoding

fn write_raw_packet(&mut self, pixels: &[u8], counter: u8) -> ImageResult<()>

Writes a raw packet to the writer

fn write_rle_encoded_packet( &mut self, pixel: &[u8], counter: u8, ) -> ImageResult<()>

Writes a run-length encoded packet to the writer

fn run_length_encode( &mut self, image: &[u8], color_type: ColorType, ) -> ImageResult<()>

Writes the run-length encoded buffer to the writer

pub fn encode( self, buf: &[u8], width: u32, height: u32, color_type: ColorType, ) -> ImageResult<()>

Encodes the image buf that has dimensions width and height and ColorType color_type.

The dimensions of the image must be between 0 and 65535 (inclusive) or an error will be returned.

Panics

Panics if width * height * color_type.bytes_per_pixel() != data.len().

Trait Implementations

impl<W: Write> ImageEncoder for TgaEncoder<W>

fn write_image( self, buf: &[u8], width: u32, height: u32, color_type: ColorType, ) -> ImageResult<()>

Writes all the bytes in an image to the encoder.
