pub fn size(&self) -> [usize; 2]

The size of the image data (number of pixels wide/high).

pub fn size_vec2(&self) -> Vec2

The size of the image data (number of pixels wide/high).

pub fn debug_name(&self) -> &str

The debug name of the image, e.g. the file name.

pub fn texture_id(&self, ctx: &Context) -> TextureId

The texture if for this image.

pub fn show_max_size(&self, ui: &mut Ui, max_size: Vec2) -> Response

Show the image with the given maximum size.

pub fn show(&self, ui: &mut Ui) -> Response

Show the image with the original size (one image pixel = one gui point).

pub fn show_scaled(&self, ui: &mut Ui, scale: f32) -> Response

Show the image with the given scale factor (1.0 = original size).

pub fn show_size(&self, ui: &mut Ui, desired_size: Vec2) -> Response

Show the image with the given size.
