Source

fn parse_file<R: Read + Seek>( &mut self, file: &mut R, max_chained: Option<usize>, sub_tags: &[u16], ) -> Result<()>

Construct a TIFF reader from Read capable objects

corr is a correction value that should be applied to offsets received from file structure.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
