impl Display

pub fn new(
    display_identifier: impl Into<String>
) -> Result<Self, DisplayCreationError>

Open a display to X server using XOpenDisplay at specified display domain

if let Ok(display) = Display::new(":0.0") {
	// do something with display
}

If the call to XOpenDisplay fails, or if display_identifier couldn’t be converted to a C String, then this function will return a DisplayCreationError with details

pub fn screenshot(&self) -> Result<Image, ()>

Take a screenshot of the display.

if let Ok(display) = Display::new(":0.0") {
	let screenshot = display.screenshot();
	#[cfg(feature = "save")]
	// With "save" feature enabled
	screenshot.unwrap().save_as("./screenshot.png");
	#[cfg(not(feature = "save"))]
	// Access to raw image data without "save" feature
	let raw_data = unsafe { screenshot.unwrap().as_raw_slice() };
}

Errors

This function fails silently if the call to XGetImage fails for some reason.
