Trait Implementations

impl<'a> AnimationDecoder<'a> for GenericImageDecoder<'a>

See documentation on impl image::ImageDecoder

fn into_frames(self) -> Frames<'a>

Consume the decoder producing a series of frames.

fn loop_count(&self) -> LoopCount

Loop count of the animated image.

impl<'a> Debug for GenericImageDecoder<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> ImageDecoder for GenericImageDecoder<'a>

Notice that we implement methods that are implemented by default. However, these methods are necessary as the default implementation will return not correct defaults.

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 read_image(self, buf: &mut [u8]) -> ImageResult<()>

where Self: Sized,

Returns all the bytes in the image.

fn read_image_boxed(self: Box<Self>, buf: &mut [u8]) -> ImageResult<()>

Use read_image instead; this method is an implementation detail needed so the trait can be object safe.

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

Returns the ICC color profile embedded in the image, or Ok(None) if the image does not have one.

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

Returns the raw Exif chunk, if it is present. A third-party crate such as kamadak-exif is required to actually parse it.

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

Returns the raw XMP chunk, if it is present. A third-party crate such as roxmltree is required to actually parse it.

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

Returns the raw IPTC chunk, if it is present.

fn original_color_type(&self) -> ExtendedColorType

Returns the color type of the image file before decoding

fn orientation(&mut self) -> Result<Orientation, ImageError>

Returns the orientation of the image.

fn total_bytes(&self) -> u64

Returns the total number of bytes in the decoded image.

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

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