Struct openexr::multi_part::multi_part_output_file::MultiPartOutputFile

#[repr(transparent)]
pub struct MultiPartOutputFile(_);

Manages writing multi-part images.

Multi-part files are essentially just containers around multiple OutputFiles

Certain attributes are shared between all parts:

• displayWindow
• pixelAspectRatio
• timeCode
• chromaticities

Implementations

impl MultiPartOutputFile

pub fn new<P: AsRef<Path>>(
    filename: P,
    headers: &HeaderSlice,
    override_shared_attributes: bool,
    num_threads: i32
) -> Result<MultiPartOutputFile, Error>

Creates a new multi-part output file from a slice of slice of headers with the given filename. If override_shared_attributes is true, then mismatching attributes between headers will be overriden with the value from the first header. If false then Error::InvalidArgument is returned instead.

Errors

• Error::InvalidArgument - if override_shared_attributes is false and there is a mismatch between headers’ common attributes, or if each header does not have a unique name.
• Error::Base - if the file cannot be opened.

pub fn parts(&self) -> i32

The number of parts in the file

pub fn header(&self, n: i32) -> Result<HeaderRef<'_>, Error>

Return a Header for part n.

Due to enforcing attribute sharing, the attributes of the returned Header may be different from the matching one passed in to the constructor.

Errors

• Error::InvalidArgument - if n does not correspond to a part in the file.
