Struct CGImage 

pub struct CGImage { /* private fields */ }

CGImage wrapper for screenshots

Represents a Core Graphics image returned from screenshot capture.

Examples

let content = SCShareableContent::get()?;
let display = &content.displays()[0];
let filter = SCContentFilter::builder().display(display).exclude_windows(&[]).build();
let config = SCStreamConfiguration::default();

let image = SCScreenshotManager::capture_image(&filter, &config)?;
println!("Screenshot size: {}x{}", image.width(), image.height());

Implementations

impl CGImage

pub fn width(&self) -> usize

Get image width in pixels

Examples

let image = SCScreenshotManager::capture_image(&filter, &config)?;
let width = image.width();
println!("Width: {}", width);

pub fn height(&self) -> usize

Get image height in pixels

pub fn as_ptr(&self) -> *const c_void

pub fn get_rgba_data(&self) -> Result<Vec<u8>, SCError>

Get raw RGBA pixel data

Returns a vector containing RGBA bytes (4 bytes per pixel). The data is in row-major order.

Errors

Returns an error if the pixel data cannot be extracted
