Implementations

impl Image

pub fn size_in_pixels(&self, cx: &mut Cx) -> Option<(usize, usize)>

Returns the original size of the image in pixels (not its displayed size).

Returns None if the image has not been loaded into a texture yet.

pub fn has_texture(&self) -> bool

True if a texture has been set on this Image.

pub fn draw_walk(&mut self, cx: &mut Cx2d<'_, '_>, walk: Walk) -> DrawStep

pub fn load_image_file_by_path_async( &mut self, cx: &mut Cx, image_path: &Path, ) -> Result<(), ImageError>

Loads the image at the given image_path on disk into this ImageRef.

pub fn load_image_from_data_async( &mut self, cx: &mut Cx, image_path: &Path, data: Arc<Vec<u8>>, ) -> Result<(), ImageError>
