Struct dui::image::Image

pub struct Image(_);

A one-channel image which each pixel is a byte index to a pallet of RGB colors.

The image is meant to be shown on a label, button, toggle, or as a cursor.

See the [IUP Image Documentation][1]. [1]: http://webserver2.tecgraf.puc-rio.br/iup/en/elem/iupimage.html

Methods

impl Image

pub fn set_colors<U>(&mut self, colors: U) -> Image where
    U: AsRef<[(u8, u8, u8)]>, 

Sets the pallet of colors to be used by the pixels.

This is a shortcut to the 0, 1, 2, ..., i attributes.

Panics

Panics if the length of the colors pallet is greater than 256.
