A DESCRIPTION OF THE PROBLEM :
Java 1.4 now supports copy/paste of images from outside apps via
Transferable and DataFlavor.imageFlavor. However calling
getTransferData(DataFlavor.imageFlavor) results in a BufferedImage
object that does not contain alpha data:
type = 1 DirectColorModel: rmask=ff0000 gmask=ff00 bmask=ff amask=0
IntegerInterleavedRaster: width = 80 height = 50 #Bands = 3 xOff = 0 yOff = 0
The means that if, for example a user copies a
transparent gif from their browser and pastes it into a java app, the
resulting image will not contain the alpha data, and I my testing, the
transparent pixels are black.
This shortcoming seriously
undermines any claim of image copy/paste that could be made for a java
This bug can be reproduced always.
