Trait containing all Texture methods.

Required Methods§

source

fn height(&self) -> i32

Returns the height of the @self, in pixels.

fn width(&self) -> i32

Returns the width of @self, in pixels.

fn save_to_png(&self, filename: impl AsRef<Path>) -> Result<(), BoolError>

Store the given @self to the @filename as a PNG file.

This is a utility function intended for debugging and testing. If you want more control over formats, proper error handling or want to store to a gio::File or other location, you might want to use save_to_png_bytes() or look into the gdk-pixbuf library.
