### Description of the callback interface
| Callback interface | Callback field | Description of callback data |
|------------------------------|-------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| onLoadStart | req: ImageKnifeRequest | The req return field contains information about the image request, such as the url of the image and the width and height of its components, while ImageKnifeRequest contains ImageKnifeData, which contains the start of the request and the point at which it checks the memory cache |
| onLoadSuccess | data: string \| PixelMap \| undefined, imageData: ImageKnifeData, req?: ImageKnifeRequest | data: The result data is loaded successfully. imageData: information stored in the cache of the image, req: information of the image request, and ImageKnifeData, including the original size of the image in the request, image decoding size, format, picture frame, request end time, disk check time, network request start and end, image decoding start and end and other time points |
| onLoadFailed | err: string, req?: ImageKnifeRequest | err: indicates error information. req: Information of image request. Meanwhile, ImageKnifeData contains the error information of the request (ErrorInfo, TimeInfo). ErrorInfo contains the error phase, error code and the error code of network request. TimeInfo contains the end time of the request, the disk check time, the start and end of the network request, and the start and end of the image decoding |
| onLoadCancel | reason: string, req?: ImageKnifeRequest | reason: indicates the reason for canceling the callback. req: Information of image request. Meanwhile, ImageKnifeData contains the error information of the request (ErrorInfo, TimeInfo). ErrorInfo contains the error phase, error code and the error code of network request. TimeInfo contains the end time of the request, the disk check time, the start and end of the network request, the start and end of the image decoding, and the request cancellation |
