Log

Tip

The following example takes precedence over the Compose version component for demonstration
ZoomState.zoomable is equivalent to ZoomImageView.zoomable
ZoomState.subsampling is equivalent to ZoomImageView.subsampling

ZoomImage generates some logs during its run, which can help you find the problem when something goes wrong and help you understand it How ZoomImage works.

Logger

The Logger class encapsulates the print, level control, and output pipelines of logs

level

The Logger.level property controls the print level of the log, the default is INFO, you can modify it to expand the output range of the log

Example:

val zoomState: ZoomState by rememberSketchZoomState()

zoomState.logger.level = Logger.DEBUG

SketchZoomAsyncImage(
    uri = "https://sample.com/sample.jpeg",
    contentDescription = "view image",
    modifier = Modifier.fillMaxSize(),
    zoomState = zoomState,
)

pipeline

The Logger.pipeline property controls the output pipeline of the log, and the default is AndroidLogPipeline to output to Android console, you can modify it to output logs elsewhere

Example:

val zoomState: ZoomState by rememberSketchZoomState()

zoomState.logger.pipeline = MyLoggerPipeline()

SketchZoomAsyncImage(
    uri = "https://sample.com/sample.jpeg",
    contentDescription = "view image",
    modifier = Modifier.fillMaxSize(),
    zoomState = zoomState,
)
