Struct eframe::IconData

pub struct IconData {
    pub rgba: Vec<u8>,
    pub width: u32,
    pub height: u32,
}

Image data for an application icon.

Use a square image, e.g. 256x256 pixels. You can use a transparent background.

Fields

rgba: Vec<u8>

RGBA pixels, with separate/unmultiplied alpha.

width: u32

Image width. This should be a multiple of 4.

height: u32

Image height. This should be a multiple of 4.

Implementations

impl IconData

pub fn try_from_png_bytes(png_bytes: &[u8]) -> Result<Self, ImageError>

Convert into image::RgbaImage

Errors

If this is not a valid png.

pub fn to_image(&self) -> Result<RgbaImage, String>

Convert into image::RgbaImage

Errors

If width*height != 4 * rgba.len(), or if the image is too big.

pub fn to_png_bytes(&self) -> Result<Vec<u8>, String>

Encode as PNG.

Errors

The image is invalid, or the PNG encoder failed.
