Changes since previous Aminet release:

 - Fixed bug which caused SplitMultiImage to save multiple copies of the
   same image for files containing only one image, when the datatype does
   not support PDTA_GetNumPictures.


DESCRIPTION

Starting with AmigaOS 3.5, the picture.datatype documentation defined two
new tags (PDTA_GetNumPictures and PDTA_WhichPicture), which allowed
subclasses to return different images from the same file, where relevant.
For example, TIFF image files often contain more than one image, and
WarpTIFF.datatype is able to decode any of those images on request,
returning any of the images to the application.

Unfortunately, not many applications have made use of this feature (at the
time of writing, PicShow is the only one I'm aware of) and can therefore
read only the first image in a file.  After requests from WarpTIFF users
wanting to know of software capable of reading all the pages in multi-page
TIFF fax files, I decided to write SplitMultiImage.  Although not as nice
as Multiview having this capability built-in, SplitMultiImage at least
allows all the images to be viewed by extracting all the images from a file
and saving them separately as IFF-ILBM files.

SplitMultiImage is not restricted to TIFF files - in theory, it will work
with any datatypes supporting the new tags and for image formats that can
contain multiple images.
