Struct imagine::bitmaps::BitmapRGBA8

pub struct BitmapRGBA8 { /* fields omitted */ }

A grid of RGBA8 values, with a width and height.

• The (0,0) position is UNSPECIFIED, and depends on context.
  • If the bitmap is part of a parsed file then the file format probably has a convention.
  • Image files usually place the origin in the Top Left, but OpenGL places (0,0) in the Bottom Left.

Methods

impl BitmapRGBA8

pub fn new(width: usize, height: usize) -> Self

Makes a new bitmap of default pixels.

pub fn width(&self) -> usize

Width of the bitmap.

pub fn height(&self) -> usize

Height of the bitmap.

pub fn pixels(&self) -> &[RGBA8]

pub fn pixels_mut(&mut self) -> &mut [RGBA8]

pub fn index_two_scanlines_mut(
    &mut self,
    a: usize,
    b: usize
) -> (&mut [RGBA8], &mut [RGBA8])

Grabs two scanlines mutably. Kinda like "split at mut".

Panics

• If a == b.
• If a or b are illegal index values.

pub fn flip_scanlines(&mut self)

Vertically flip all the scanlines of the image.
