Trait gdk4::prelude::TextureExt

pub trait TextureExt: 'static {
    fn height(&self) -> i32;
    fn width(&self) -> i32;
    fn save_to_png<P: AsRef<Path>>(&self, filename: P) -> bool;
}

Trait containing all Texture methods.

Implementors

GLTexture, MemoryTexture, Texture

Required methods

fn height(&self) -> i32

Returns the height of the self, in pixels.

Returns

the height of the Texture

fn width(&self) -> i32

Returns the width of self, in pixels.

Returns

the width of the Texture

fn save_to_png<P: AsRef<Path>>(&self, filename: P) -> bool

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 GFile or other location, you might want to look into using the gdk-pixbuf library.

filename

the filename to store to

Returns

true if saving succeeded, false on failure.
