Struct winit::Icon [−][src]
pub struct Icon { /* fields omitted */ }
An icon used for the window titlebar, taskbar, etc.
Enabling the icon_loading
feature provides you with several convenience methods for creating
an Icon
from any format supported by the image
crate.
Methods
impl Icon
[src]
impl Icon
pub fn from_rgba(
rgba: Vec<u8>,
width: u32,
height: u32
) -> Result<Self, BadIcon>
[src]
pub fn from_rgba(
rgba: Vec<u8>,
width: u32,
height: u32
) -> Result<Self, BadIcon>
Creates an Icon
from 32bpp RGBA data.
The length of rgba
must be divisible by 4, and width * height
must equal
rgba.len() / 4
. Otherwise, this will return a BadIcon
error.
pub fn from_path<P: AsRef<Path>>(path: P) -> ImageResult<Self>
[src]
pub fn from_path<P: AsRef<Path>>(path: P) -> ImageResult<Self>
Loads an Icon
from the path of an image on the filesystem.
Requires the icon_loading
feature.
pub fn from_reader<R: BufRead + Seek>(
reader: R,
format: ImageFormat
) -> ImageResult<Self>
[src]
pub fn from_reader<R: BufRead + Seek>(
reader: R,
format: ImageFormat
) -> ImageResult<Self>
Loads an Icon
from anything implementing BufRead
and Seek
.
Requires the icon_loading
feature.
pub fn from_bytes(bytes: &[u8]) -> ImageResult<Self>
[src]
pub fn from_bytes(bytes: &[u8]) -> ImageResult<Self>
Loads an Icon
from the unprocessed bytes of an image file.
Uses heuristics to determine format.
Requires the icon_loading
feature.
pub fn from_bytes_with_format(
bytes: &[u8],
format: ImageFormat
) -> ImageResult<Self>
[src]
pub fn from_bytes_with_format(
bytes: &[u8],
format: ImageFormat
) -> ImageResult<Self>
Loads an Icon
from the unprocessed bytes of an image.
Requires the icon_loading
feature.
