[][src]Enum png::BlendOp

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

How pixels are written into the buffer.

Variants

Source

Pixels overwrite the value at their position.

Over

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

Methods

impl BlendOp[src]

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