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

pub 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.

pub 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.

pub fn from_buffer<C>(src: &[u32], width: i32, mask_color: C) -> Self where
    C: Into<Color>, 

Create a instance from a buffer of Color data.

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

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

pub fn open<P>(path: P) -> Result<Self, Box<dyn 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.

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

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

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

Get the size of the buffer in pixels.

pub fn width(&self) -> i32

Get the width of the buffer in pixels.

pub fn height(&self) -> i32

Get the height of the buffer in pixels.

pub fn mask_color(&self) -> Color

Get the color of the mask.

pub fn to_raw_buffer(&self) -> Vec<u32>

Get the raw pixels buffer, this is a costly operation.
