Struct cosmic::iced_widget::renderer::graphics::image::image_rs::codecs::dds::DdsDecoder

pub struct DdsDecoder<R>
where
    R: Read,
{ /* private fields */ }

The representation of a DDS decoder

Implementations

impl<R> DdsDecoder<R>

where R: Read,

pub fn new(r: R) -> Result<DdsDecoder<R>, ImageError>

Create a new decoder that decodes from the stream r

Trait Implementations

impl<'a, R> ImageDecoder<'a> for DdsDecoder<R>

where R: 'a + Read,

type Reader = DxtReader<R>

The type of reader produced by into_reader.

fn dimensions(&self) -> (u32, u32)

Returns a tuple containing the width and height of the image

fn color_type(&self) -> ColorType

Returns the color type of the image data produced by this decoder

fn scanline_bytes(&self) -> u64

👎Deprecated: Planned for removal. See https://github.com/image-rs/image/issues/1989

Returns the minimum number of bytes that can be efficiently read from this decoder. This may be as few as 1 or as many as total_bytes().

fn into_reader( self, ) -> Result<<DdsDecoder<R> as ImageDecoder<'a>>::Reader, ImageError>

👎Deprecated: Planned for removal. See https://github.com/image-rs/image/issues/1989

Returns a reader that can be used to obtain the bytes of the image. For the best performance, always try to read at least scanline_bytes from the reader at a time. Reading fewer bytes will cause the reader to perform internal buffering.

fn read_image(self, buf: &mut [u8]) -> Result<(), ImageError>

Returns all the bytes in the image.

fn original_color_type(&self) -> ExtendedColorType

Returns the color type of the image file before decoding

fn icc_profile(&mut self) -> Option<Vec<u8>>

Returns the ICC color profile embedded in the image

fn total_bytes(&self) -> u64

Returns the total number of bytes in the decoded image.

fn read_image_with_progress<F>( self, buf: &mut [u8], progress_callback: F, ) -> Result<(), ImageError>

where F: Fn(Progress),

👎Deprecated: Use read_image instead. See https://github.com/image-rs/image/issues/1989

Same as read_image but periodically calls the provided callback to give updates on loading progress.

fn set_limits(&mut self, limits: Limits) -> Result<(), ImageError>

Set decoding limits for this decoder. See Limits for the different kinds of limits that is possible to set.
