Trait containing all Texture methods.

Required Methods§

source

fn format(&self) -> MemoryFormat

Available on crate feature v4_10 only.

Gets the memory format most closely associated with the data of the texture.

Note that it may not be an exact match for texture data stored on the GPU or with compression.

The format can give an indication about the bit depth and opacity of the texture and is useful to determine the best format for downloading the texture.

Returns

the preferred format for the texture’s data

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.
