Hello All,
I am replying to the last mail in this thread. >From the test case we can see that it is not strict about pixel data which was >transferred during DnD. It is just making sure we are able to do DnD for all >native image formats. In test case ImageTransferer. areImagesIdentical() function we can see that for JPEG & GIF(lossy formats) they are ignoring the pixel data. And for all other image formats except PNG they are not checking alpha channel and only checking RGB data. So I have simplified areImagesIdentical() function also. I have verified this latest test case in Windows(native image flavours : PNG JFIF DIB ENHMETAFILE METAFILEPICT), Ubuntu(native image flavours : image/png image/x-png image/tiff image/gif PNG JFIF) & Mac(native image flavours : PNG JFIF TIFF) and it passes.
