Enum png::BlendOp

#[repr(u8)]
pub enum BlendOp {
    Source = 0,
    Over = 1,
}

How pixels are written into the buffer.

Variants

Source = 0

Pixels overwrite the value at their position.

Over = 1

The new pixels are blended into the current state based on alpha.

Implementations

impl BlendOp

pub fn from_u8(n: u8) -> Option<BlendOp>

u8 -> Self. Using enum_primitive or transmute is probably the right thing but this will do for now.

Trait Implementations

impl Clone for BlendOp

fn clone(&self) -> BlendOp

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlendOp

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

Formats the value using the given formatter.

impl Display for BlendOp

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

Formats the value using the given formatter.

impl PartialEq for BlendOp

fn eq(&self, other: &BlendOp) -> 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.
