Struct ScreenshotBuilder 

pub struct ScreenshotBuilder<'a> { /* private fields */ }

Builder for configuring and capturing screenshots.

Uses the browser’s native screenshot API (browser.tabs.captureVisibleTab) for accurate pixel capture without JavaScript limitations.

Example

// Capture as PNG base64
let png_data = tab.screenshot().png().capture().await?;

// Capture as JPEG and save to file
tab.screenshot().jpeg(80).save("page.jpg").await?;

Implementations

impl<'a> ScreenshotBuilder<'a>

pub fn png(self) -> Self

Sets PNG format (default).

pub fn jpeg(self, quality: u8) -> Self

Sets JPEG format with quality (0-100).

pub fn format(self, format: ImageFormat) -> Self

Sets the image format.

pub async fn capture(&self) -> Result<String>

Captures the screenshot and returns base64-encoded data.

Uses the browser’s native captureVisibleTab API for accurate capture.

pub async fn capture_bytes(&self) -> Result<Vec<u8>>

Captures the screenshot and returns raw bytes.

pub async fn save(&self, path: impl AsRef<Path>) -> Result<()>

Captures the screenshot and saves to a file.

The format is determined by the builder settings, not the file extension.
