Struct png::OutputInfo

pub struct OutputInfo {
    pub width: u32,
    pub height: u32,
    pub color_type: ColorType,
    pub bit_depth: BitDepth,
    pub line_size: usize,
}

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.

Trait Implementations

impl Debug for OutputInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<OutputInfo> for OutputInfo

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.
