screencapturekit 3.0.1

//! `SCScreenshotManager` - Single-shot screenshot capture
//!
//! Available on macOS 14.0+.
//! Provides high-quality screenshot capture without the overhead of setting up a stream.
//!
//! ## When to Use
//!
//! Use `SCScreenshotManager` when you need:
//! - A single screenshot rather than continuous capture
//! - Quick capture without stream setup/teardown overhead
//! - Direct saving to image files
//!
//! For continuous capture, use [`SCStream`](crate::stream::SCStream) instead.
//!
//! ## Example
//!
//! ```no_run
//! use screencapturekit::screenshot_manager::{SCScreenshotManager, ImageFormat};
//! use screencapturekit::stream::{content_filter::SCContentFilter, configuration::SCStreamConfiguration};
//! use screencapturekit::shareable_content::SCShareableContent;
//!
//! # fn example() -> Result<(), Box<dyn std::error::Error>> {
//! let content = SCShareableContent::get()?;
//! let display = &content.displays()[0];
//! let filter = SCContentFilter::create().with_display(display).with_excluding_windows(&[]).build();
//! let config = SCStreamConfiguration::new()
//!     .with_width(1920)
//!     .with_height(1080);
//!
//! // Capture as CGImage
//! let image = SCScreenshotManager::capture_image(&filter, &config)?;
//! println!("Screenshot: {}x{}", image.width(), image.height());
//!
//! // Save to file
//! image.save_png("/tmp/screenshot.png")?;
//!
//! // Or save as JPEG with quality
//! image.save("/tmp/screenshot.jpg", ImageFormat::Jpeg(0.85))?;
//! # Ok(())
//! # }
//! ```
