如何投/转换一个BufferedImage成图像? [英] How to cast/convert a BufferedImage into an Image?
问题描述
我想转换一个的BufferedImage
到 java.awt.Image中
。
我的源图像TIF所以我用JAI读它为 PlanarImage
:
My source-image is tif so I use JAI to read it as PlanarImage
:
PlanarImage源= JAI.create(fileload,IMG_DIR + tagImgName);
PlanarImage source = JAI.create("fileload", IMG_DIR + tagImgName);
我然后将其保存为对象的属性作为的BufferedImage
I then save it as an objects attribute as a BufferedImage
tagImg = source.getAsBufferedImage();
tagImg = source.getAsBufferedImage();
有关.PDF-出口(通过iText的),我需要它作为 java.awt.Image中
For .pdf-Export (via iText) I need it as java.awt.Image
谢谢!
推荐答案
的 java.awt.image.BufferedImage中是已经的 java.awt.Image中,所以你不需要任何铸造或转产。您可以使用的BufferedImage代替图像。
java.awt.image.BufferedImage is 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.
您可以直接做到这一点:
You can do directly this:
Image tagImg = source.getAsBufferedImage();
// use tagImg with iText library here
