Provided Methods

unsafe fn scannerDeviceView_didScanToURL_fileData_error( &self, scanner_device_view: Option<&IKScannerDeviceView>, url: Option<&NSURL>, data: Option<&NSData>, error: Option<&NSError>, )

where Self: Sized + Message,

This message is sent for each image that gets scanned.

Based on the IKScannerDeviceViewTransferMode the downloaded file will be saved on disk using the ‘url’, or returned in memory as NSData

Safety

• scanner_device_view might not allow None.
• url might not allow None.
• data might not allow None.
• error might not allow None.

unsafe fn scannerDeviceView_didScanToURL_error( &self, scanner_device_view: Option<&IKScannerDeviceView>, url: Option<&NSURL>, error: Option<&NSError>, )

where Self: Sized + Message,

For file based transfer this message is sent for each image that gets scanned.

Based on the IKScannerDeviceViewTransferMode the downloaded file will be saved on disk using the ‘url’, or returned in memory as NSData

Safety

• scanner_device_view might not allow None.
• url might not allow None.
• error might not allow None.

unsafe fn scannerDeviceView_didScanToBandData_scanInfo_error( &self, scanner_device_view: Option<&IKScannerDeviceView>, data: Option<&ICScannerBandData>, scan_info: Option<&NSDictionary>, error: Option<&NSError>, )

where Self: Sized + Message,

Available on crate feature objc2-image-capture-core only.

For memory a based transfer this message is sent for every time an image band of data was scanned.

The ‘data’ parameter describes the scanned image data. Note that rotation/cropping/image adjustments are not applied yet. The ‘scanInfo’ parameter contains additional information (rotation angle, …) that should be applied once the scan is completed.

Safety

• scanner_device_view might not allow None.
• data might not allow None.
• scan_info generic should be of the correct type.
• scan_info might not allow None.
• error might not allow None.

unsafe fn scannerDeviceView_didEncounterError( &self, scanner_device_view: Option<&IKScannerDeviceView>, error: Option<&NSError>, )

where Self: Sized + Message,

This message is sent every time the scanner device reports an error.

Safety

• scanner_device_view might not allow None.
• error might not allow None.
