pub struct OpenExrDecoder<R> { /* private fields */ }
Expand description
An OpenEXR decoder. Immediately reads the meta data from the file.
Implementations§
source§impl<R: Read + Seek> OpenExrDecoder<R>
impl<R: Read + Seek> OpenExrDecoder<R>
sourcepub fn new(source: R) -> ImageResult<Self>
pub fn new(source: R) -> ImageResult<Self>
Create a decoder. Consumes the first few bytes of the source to extract image dimensions.
Assumes the reader is buffered. In most cases,
you should wrap your reader in a BufReader
for best performance.
Loads an alpha channel if the file has alpha samples.
Use with_alpha_preference
if you want to load or not load alpha unconditionally.
sourcepub fn with_alpha_preference(
source: R,
alpha_preference: Option<bool>,
) -> ImageResult<Self>
pub fn with_alpha_preference( source: R, alpha_preference: Option<bool>, ) -> ImageResult<Self>
Create a decoder. Consumes the first few bytes of the source to extract image dimensions.
Assumes the reader is buffered. In most cases,
you should wrap your reader in a BufReader
for best performance.
If alpha preference is specified, an alpha channel will
always be present or always be not present in the returned image.
If alpha preference is none, the alpha channel will only be returned if it is found in the file.

👎Deprecated: Planned for removal. See https://github.com/image-rs/image/issues/1989
fn into_reader(self) -> ImageResult<Self::Reader>
Use read_image
instead if possible,
as this method creates a whole new buffer just to contain the entire image.
