Enum png::BlendOp

source · [−]

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

Expand description

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.

Implementations

source

impl BlendOp

source

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.
