问题描述
我有一个从磁盘加载的图像(存储为 BufferedImage)，我在 JPanel 上正确显示，但是当我尝试使用下面的命令，图像以偏红色调保存.
i have a loaded image from disk (stored as a BufferedImage), which i display correctly on a JPanel but when i try to re-save this image using the command below, the image is saved in a reddish hue.
ImageIO.write(image, "jpg", fileName);
注意！image 是一个 BufferedImage 和 fileName 是一个 File 对象，指向将被保存的以.jpg".
Note! image is a BufferedImage and fileName is a File object pointing to the filename that will be saved which end in ".jpg".
我已经读到早期 JDK 中的 ImageIO 方法存在问题，但据我所知，我不是在这些版本之一上.我正在寻找的是一种无需更新 JDK 即可解决此问题的方法，但是尽管说我仍然想知道在什么 JDK 中修复了此问题(如果它确实仍然是我正在使用的 JDK 的错误)).
I have read that there were problems with ImageIO methods in earlier JDKs but i'm not on one of those versions as far as i could find. What i am looking for is a way to fix this issue without updating the JDK, however having said that i would still like to know in what JDK this issue was fixed in (if it indeed is still a bug with the JDK i'm using).
谢谢.
推荐答案
好的，解决了我的问题，看来我出于某种原因需要将图像转换为 BufferedImage.TYPE_INT_RGB.我认为 alpha 通道可能在某些层没有正确处理.
Ok, solved my problem, it seems that i need to convert the image to BufferedImage.TYPE_INT_RGB for some reason. I think the alpha channels might not be handled correctly at some layer.
