Implementations

impl Icon

pub fn from_rgba( rgba: Vec<u8>, width: u32, height: u32, ) -> Result<Icon, 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>(path: P, size: Option<(u32, u32)>) -> Result<Icon, BadIcon>

where P: AsRef<Path>,

Create an icon from a file path.

Specify size to load a specific icon size from the file, or None to load the default icon size from the file.

In cases where the specified size does not exist in the file, Windows may perform scaling to get an icon of the desired size.

pub fn from_resource( ordinal: u16, size: Option<(u32, u32)>, ) -> Result<Icon, BadIcon>

Create an icon from a resource embedded in this executable or library.

Specify size to load a specific icon size from the file, or None to load the default icon size from the file.

In cases where the specified size does not exist in the file, Windows may perform scaling to get an icon of the desired size.
