Expand description

Output info.

This describes one particular frame of the image that was written into the output buffer.

Fields§

§width: u32

The pixel width of this frame.

§height: u32

The pixel height of this frame.

§color_type: ColorType

The chosen output color type.

§bit_depth: BitDepth

The chosen output bit depth.

§line_size: usize

The byte count of each scan line in the image.

Implementations§

source§

impl OutputInfo

source

pub fn buffer_size(&self) -> usize

Returns the size needed to hold a decoded frame If the output buffer was larger then bytes after this count should be ignored. They may still have been changed.

impl PartialEq for OutputInfo

source§

fn eq(&self, other: &OutputInfo) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
