java将jpg另存为png

Question

我在磁盘上有一个 jpg 文件的图像。我想转换并保存为png并删除原始jpg。在 Java 中执行此操作的最佳方法是什么？

String justNameJpg = "something.jpg";
String justNamePng = ImageEditor.GetImageNameNoExtension(justName) + "." + "png";
java.awt.image.BufferedImage bufferedImage = ImageIO.read(new File(folder, justNameJpg));
ImageIO.write(bufferedImage, "png", new File(folder, justNamePng));

Answer 1

如果你想使用 ImageIO 这应该工作：

ImageIO.write(image, "png", new File("new output file name"));
