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

impl OutputInfo

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.
