Struct Surface 

pub struct Surface {
    pub px: Vec<u8>,
    pub w: i32,
    pub h: i32,
    pub stride: i32,
    pub fmt: u8,
    pub flags: u8,
    pub opac: u8,
    pub blend: u8,
}

pixels of one image: rows of stride bytes (4 per pixel, A8: 1)

Fields

px: Vec<u8>

w: i32

h: i32

stride: i32

fmt: u8

flags: u8

opac: u8

blend: u8

Implementations

impl Surface

pub fn new(w: i32, h: i32, fmt: u8) -> Surface

zeroed pixels, stride 64-byte aligned; sides outside 0..65536 give an empty surface (surf_alloc fails). Byte lengths beyond the target’s addressable allocation size also give an empty surface, before allocating pixels.

pub fn try_new(w: i32, h: i32, fmt: u8) -> Option<Surface>

like new, but None (instead of an empty surface or an abort) when the size is invalid or the memory is not there (try_zeroed). For sizes that come from a file or from the user.

pub fn new_a8_packed(w: i32, h: i32) -> Surface

a tightly packed A8 surface (glyph masks: stride = w)

pub fn resize(&mut self, w: i32, h: i32)

new size, same format; the contents are NOT kept [surf_resize]

pub fn bpp(&self) -> usize

bytes per pixel

Trait Implementations

impl Default for Surface

fn default() -> Surface

Returns the “default value” for a type.
