How to cast/convert a BufferedImage into an Image?
提问by Gundon
I would like to convert a BufferedImageto an java.awt.Image.
我想将 a 转换BufferedImage为java.awt.Image.
My source-image is tif so I use JAI to read it as PlanarImage:
我的源图像是 tif，所以我使用 JAI 将其读取为PlanarImage：
PlanarImage source = JAI.create("fileload", IMG_DIR + tagImgName);
PlanarImage source = JAI.create("fileload", IMG_DIR + tagImgName);
I then save it as an objects attribute as a BufferedImage
然后我将它保存为对象属性作为 BufferedImage
tagImg = source.getAsBufferedImage();
tagImg = source.getAsBufferedImage();
For .pdf-Export (via iText) I need it as java.awt.Image
对于 .pdf-Export（通过 iText），我需要它作为 java.awt.Image
Thanks!
谢谢！

java.awt.image.BufferedImageis already a subclass of java.awt.Image, so you shouldn't need any casting or converting. You can use the BufferedImage in place of a Image.
java.awt.image.BufferedImage中已经是一个子类java.awt.Image中，所以你不需要任何铸造或转换。您可以使用 BufferedImage 代替 Image。
You can do directly this:
你可以直接这样做：
Image tagImg = source.getAsBufferedImage();
// use tagImg with iText library here

Assuming you mean java.awt.image.BufferedImage, it already subclasses java.awt.image.Image- so you shouldn't need to do anything.
假设您的意思是java.awt.image.BufferedImage，它已经子类化了java.awt.image.Image- 所以您不需要做任何事情。
