Struct image::codecs::ico::IcoEncoder

pub struct IcoEncoder<W: Write> { /* private fields */ }

ICO encoder

Implementations

impl<W: Write> IcoEncoder<W>

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

Create a new encoder that writes its output to w.

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

👎Deprecated: Use IcoEncoder::write_image instead. Beware that write_image has a different endianness convention

Encodes the image image that has dimensions width and height and ColorType c. The dimensions of the image must be between 1 and 256 (inclusive) or an error will be returned.

Expects data to be big endian.

pub fn encode_images(self, images: &[IcoFrame<'_>]) -> ImageResult<()>

Takes some IcoFrames and encodes them into an ICO.

images is a list of images, usually ordered by dimension, which must be between 1 and 65535 (inclusive) in length.

Trait Implementations

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

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

Write an ICO image with the specified width, height, and color type.

For color types with 16-bit per channel or larger, the contents of buf should be in native endian.

WARNING: In image 0.23.14 and earlier this method erroneously expected buf to be in big endian.
