Struct blit::BlitBuffer

pub struct BlitBuffer { /* fields omitted */ }

A data structure holding a color and a mask buffer to make blitting on a buffer real fast.

Methods

impl BlitBuffer

fn blit(&self, dst: &mut [u32], dst_width: usize, offset: (i32, i32))

Blit the image on a buffer using bitwise operations--this is a lot faster than blit_with_mask_color.

fn blit_rect(
    &self,
    dst: &mut [u32],
    dst_width: usize,
    offset: (i32, i32),
    sub_rect: (i32, i32, i32, i32)
)

Blit a section of the image on a buffer.

fn from_buffer(src: &[u32], width: i32, mask_color: Color) -> Self

Create a instance from a buffer of Color data.

fn save<P>(&self, path: P) -> Result<(), Box<Error>> where
    P: AsRef<Path>, 

Saves the buffer to a file at the path specified. A custom binary format is used for this.

fn open<P>(path: P) -> Result<Self, Box<Error>> where
    P: AsRef<Path>, 

Create a new buffer from a file at the path specified. The file needs to be the custom binary format.

fn from_memory(buffer: &[u8]) -> Result<Self, Box<Error>>

Create a new buffer from a file at the path specified. The array needs to be the custom binary format.

fn size(&self) -> (i32, i32)

Get the size of the buffer in pixels.

Trait Implementations

impl Debug for BlitBuffer

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
