要解决Android Studio无法打开Windows照片查看器中压缩的位图图像的问题,可以使用以下代码示例:
import javax.imageio.ImageIO;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
public class ImageUtils {
public static void resizeImage(File originalImage, File resizedImage, int width, int height) throws IOException {
BufferedImage originalBufferedImage = ImageIO.read(originalImage);
BufferedImage resizedBufferedImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
Graphics2D graphics2D = resizedBufferedImage.createGraphics();
graphics2D.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
graphics2D.drawImage(originalBufferedImage, 0, 0, width, height, null);
graphics2D.dispose();
ImageIO.write(resizedBufferedImage, "jpg", resizedImage);
}
public static void main(String[] args) {
File originalImage = new File("path/to/original/image.jpg");
File resizedImage = new File("path/to/resized/image.jpg");
int width = 800; // 设置调整后的宽度
int height = 600; // 设置调整后的高度
try {
resizeImage(originalImage, resizedImage, width, height);
} catch (IOException e) {
e.printStackTrace();
}
}
}
这个代码示例演示了如何使用Java的ImageIO和Graphics2D类来调整图像的大小。要使用这个示例,您需要将“path/to/original/image.jpg”替换为您要调整大小的原始图像的文件路径,将“path/to/resized/image.jpg”替换为调整大小后图像的保存路径,并根据需要设置调整后的宽度和高度。
请注意,这个示例假设您安装了Java开发环境,并且在您的项目中包含了Java标准库。
