同学,可以创建一个函数来处理图像源的加载和释放,确保在切换时不会造成资源泄露。比如下面的代码:import { image } from '@kit.ImageKit'; import { BusinessError } from '@kit.BasicServicesKit'; let currentImageSource = null; function switchImageSource(newPath) { if (currentImageSource) { currentImageSource.release().then(() => { console.info('Previous image source released.'); }).catch((error: BusinessError) => { console.error('Failed to release image source: ' + error.message); }); } currentImageSource = image.createImageSource(newPath); currentImageSource.createPixelMap().then((pixelMap) => { console.info('New image loaded and PixelMap created.'); // Display pixelMap or further process here }).catch((error: BusinessError) => { console.error('Failed to create PixelMap: ' + error.message); }); } switchImageSource('path/to/initialImage.jpg'); // Initial load // Call switchImageSource with new paths as needed
