Struct Strip 

pub struct Strip {
    pub x: u16,
    pub y: u16,
    /* private fields */
}

A strip.

Fields

x: u16

The x coordinate of the strip, in user coordinates.

y: u16

The y coordinate of the strip, in user coordinates.

Implementations

impl Strip

pub fn new(x: u16, y: u16, alpha_idx: u32, fill_gap: bool) -> Self

Creates a new strip.

pub fn sentinel(y: u16, alpha_idx: u32) -> Self

Creates a sentinel strip.

pub fn is_sentinel(&self) -> bool

Return whether the strip is a sentinel strip.

pub fn strip_y(&self) -> u16

Return the y coordinate of the strip, in strip units.

pub fn width_to(&self, next: &Self) -> u16

Returns the horizontal pixel width of this strip.

IMPORTANT: This assumes that the next is actually the next adjacent strip to self, otherwise this method will return a garbage value!

pub fn alpha_idx(&self) -> u32

Returns the alpha index.

pub fn set_alpha_idx(&mut self, alpha_idx: u32)

Sets the alpha index.

Note that the largest value that can be stored in the alpha index is u32::MAX << 1, as the highest bit is reserved for fill_gap.

pub fn fill_gap(&self) -> bool

Returns whether the gap that lies between this strip and the previous in the same row should be filled.

pub fn set_fill_gap(&mut self, fill: bool)

Sets whether the gap that lies between this strip and the previous in the same row should be filled.
