After a long delay, the promised updates to all the Warp picture datatypes for 68k, WarpOS and MorphOS are finally here. To accompany the new release is the brand new WarpDT portal at http://www.warpdt.co.uk where you can keep up to date with the latest versions of the WarpDTs and download them all in one easy place. Summary of changes since previous versions:

BMP/JPEG/PNG/TIFF: Minor optimizations and cleanups.
BMP/JPEG/PNG/TIFF: Bumped version to v45 since a stable release has now been reached and to reflect the jump to shareware status

BMP: Fixed problems with decoding bitfield images

JPEG: Altered descriptor file to prevent it matching LhA or LZX archives containing JPEG files (or anything else that might contain a JFIF header, other than Photoshop files)

PNG: PNG files not containing enough data are no longer treated as a fatal error. Now the part of the image that was successfully decoded is returned.
PNG: Updated with libpng 1.2.5

PNG/TIFF: Updated with zlib 1.1.4

TIFF: Now correctly converts images using the YCbCr colourspace to RGB
TIFF: Added support for JPEG decompression
TIFF: Updated to libtiff 3.6.0-beta2, including a new version of the LogLuv decoder, and numerous other bugfixes

Prefs: Various parts of code rewritten, in preparation for losing the currrent reliance on resource.library
Prefs: Minor bugfixes
Prefs: Correct Polish and Portuguese documentation now included.

Great work Oliver. Any chance you'll add a GIF datatype soon?

Oliver,

I'm thinking of registering, but I'd like to know
what happens with the datatypes after 30 days? Do
they stop working, or what is the restriction?

Thanks.

If you are using them, you shouldn't have to find out but register :)

The datatypes do not stop working after 30 days, no - I did not want to cripple the datatypes, especially during the evaluation period. I think it's important that people can experience the full power of the datatypes, rather than heavily crippling them from day one, otherwise it's impossible to see what you're really paying for. There are no particular restrictions after 30 days (although this may have to change in the future), except that you will be asked to register if you wish to continue using the datatypes.

Thanks for the prompt reply, that answered
my question :)

I have to say it is nice that we still have
some stuff actively developed :) Kudos to
you, Oliver.

IIRC Ben Hermans mentioned that the Warp datatypes will be part of OS4. Will this be the full version, or some OEM version like IBrowse?

I will be writing 4 picture datatypes for OS4, yes. These will be based on the WarpDTs, but will be developed in a different source tree. The only real difference is that all the preferences options won't be available - these are not really required for all users of the OS, and I will be preseting the optimal settings for OS4 and developing those datatypes especially optimized for OS4 where possible.

In reply to Comment 7 (Oliver Roberts):
Which would those four datatypes be? JPG/PNG/BMP/GIF?
Why not have TIF support as well:)

In reply to Comment 8 (Anonymous):
JPEG, BMP, TIFF and BMP (I have decided not to include PSD for now, at least until the support for layered images is working).

As for GIF, I haven't written a GIF datatype yet. Of course, there will be an ILBM datatype for OS4 and probably GIF too I guess, but these will probably be provided by somebody else (ported from the existing sources, for example).

In reply to Comment 10 (Oliver Roberts):
A fairer price would be $15 IMHO. This way more people would register.
I think 15 pounds is worth WarpDatatypes. But in reality too much for some datatypes. I immediately went to register. But changed my mind when I saw the price. Anyway I will probably register whatever happens. But too expensive :(

An even better price would be $10, but I fully understand
the pricing scheme of £15. There has been a lot of work
put into those datatypes so it is only fair that he can
make some money out of them.

I totally agree. I used the Warp datatypes in the days when I still had an Amiga and was impressed by the speed and configurability. So despite the fact that they (or some similar datatypes) will be part of OS4 I'll still register it to show my support (and to get to play with the prefs ofcourse). When I can get my hands on a monster machine (be it peggy or amone or whatever) that runs OS4, that is.

Great Work!

i've always disagreed with paid-for datatypes . as they are such
a neccessary part of the OS and should come with the OS. I installed
Warp datatypes because the ak ones were shareware.

As these datatypes use GPL i think Oliver is treading very dangerous ground.
people can quite rightly ask for the source.

I can also see that people will just install older versions and
never upgrade or improve them...therefore their Amiga experience
will end up degraded and they'll move to another OS where the viewing
of any picture type is free. Even Windows gives free access to these
types of files for chrisake!

I would be very surprised if these datatypes used GPL code. libjpeg and libpng are NOT gpl. Basic TIFF and BMP support can probably be coded from scratch in a day.

Anyway nothing prevents anyone from selling GPL stuff... Oh... sigh... I can feel another GPL flamewar thread coming :]

As for the "datatypes should be free"... muahahaha... some people work for the fun, others need money. That's it. People going to another OS because warpd dts are not free ? Please... That's like saying people would stop using windows because the games (or any other software, BTW) are not free. You don't _have_ to use these datatypes. Some are given with the OS, several (free) picture viewers can read these formats without datatypes, and programmers can use libjpeg or libpng to read pictures if they want.

And I would like to add that for the "Amiga" (at large) market to become (really) alive again, people have to buy stuff. No "big" production will see the light of day if people cannot be employed full time to do them.

Imagine that Oliver has a plan for a wonderful big new app, but since he has to work full time on another job to earn money he cannot spend more than 8 hours a week on it... Plus he wouldn't be very motivated if the registration rate of his sharewares was low, because that would mean that almost noone would buy his wonderful app either.

Hmm, got a bit carried away. :)

I see nothing wrong with payware datatypes. As you said, datatypes are an important part of the system, but someone who is willing to take the time to write better (faster, smaller, whatever) datatypes should be rewarded for his time - some people are content with fame, this particular developer wants fortune. So be it. If the amiga is to regain marketshare, people must be willing to *buy* amiga software. That is how progressively larger developers get attracted to the platform. We need to attract *big* developers, and the only way to do so is to *pay* for software. Linux you say? well, ask IBM's and Red Hat's customers - they are footing the bill for a lot of the cool stuff Linux has with the service contracts they have.

erm, libpng and libjpeg etc are OpenSource... but not GPL AFAIK!

They are freely available for people to use - to further the cause
of the open spec data format they support.

Whilst I agree that basic datatypes should be free, i see no problem
with SUPERIOR (faster, preferencable etc) datatypes being an addon
for the power user to choose or upgrade too.

Maybe Oliver is using his monopoly position (ak datatypes no longer
developed iirc) or maybe, as a couple of other people have said...he
wants some money for his work and time.

theres plenty of room and chance for someone else (or a team) to write
a competing datatype. competition breeds the best.

As these datatypes are in OS4, I guess Olivers been paid for these and
this shareware is for keeping the classic versions being coded? or
are they, as i said above, going to be on offer as an upgrade for OS4
people to chase?
