Hi,
If any of you have written file readers that derive from ImageIO, please =
make note of the following change. In order to accomodate filetypes that =
use multiple extensions (for example, jpeg sometimes uses .jpeg in =
addition to .jpg), I modified ImageIO::GetSupportedFileExtensions() =
from:
virtual std::string GetSupportedFileExtensions() const =3D 0;
to:
typedef std::deque<std::string> FileExtensionsListType;
virtual FileExtensionsListType GetSupportedFileExtensions() const =3D 0;
So now, instead of returning a single string, it returns a list of =
strings. The changes that need to be made to any readers are shown in =
Unsupported/MetaImage/FileIOMetaImage.cxx and .h. Besides the one for =
MetaImage, I'm not aware of any other readers, but if there are, please =
let me know and I will help you make the necessary changes.
Thanks,
-Parag
