Short: Preview of an upcoming picture viewer.
Type: pix/illu
Uploader: Christoph Feck <feck@informatik.uni-kl.de>
What's the heck?
~~~~~~~~~~~~~~~~
This is a screen grab of a TowerView session. Nice, but what is TowerView?
TowerView is an interactive 24 bit picture viewer. It is not yet released.
Ahh... tell me more!
~~~~~~~~~~~~~~~~~~~~
I have selected NTSC:Hires Laced 16 color mode, and german localization.
Note that despite of the non-square NTSC aspect, all images look correct.
Hey, they don't look correct here! Well, at least they do on my monitor.
If they don't look correct for you, you can configure the program for your
monitor. Cool!
Also note that the images are actually displayed, even they are 24 bit.
Yes, but why? TowerView has built in DIG to dither 24 bit images down to
any depth, ranging from monochrome (black and white only), up to 262,144
colors in HAM8 mode. Just change the screenmode on-the-fly, and TowerView
will rerender the images with the correct size, aspect, and colors. Wow,
that sounds awesome! Indeed :)
The palette has been optimized to allow displaying color and gray images,
as well as your preferred GUI colors. You can also choose palettes for
grayscale only, to get best looking results, if you don't have AGA. Does
it look better than VT in HAM6 mode? Hm, I think so.
What's displayed?
~~~~~~~~~~~~~~~~~
The SmallGal.JPG is a 228x240 JPEG image, as present in the ImageFX demo
archive. TowerView can load JPEGs? Sure. The picture is displayed three
times: The left image is the unmodified original (zoomed in 2x, to see the
details better). The middle image has been gamma corrected (factor 1.72 -
JPEGs often require heavy gamma correction), and a bit enhanced in contrast
and brightness. The right image is the left eye of the gal, as displayed
in the middle image. Yes, but why three times the same image? Note that
the actual image is only one time stored in memory, you can have as many
views open as you like, each with different scaling, position, balancing or
seperations, without reloading it. I see... Also note that the eye uses a
different dither method. You can choose between at least four kinds of
dithering methods (ordered1, ordered2, halftone, and random). No Floyd
Steinberg dithering? Hm, perhaps in a later version.
The zzz.ppm image has been converted and cut out from the ZZA.JPG file
(from Aminet). The right big image is the original (zoomed in 2x), and the
left one has been balanced a bit. The tiny right image has been scaled 1/2
from the original, and is displayed as negative and grayscale.
Behind the gal's eye, you can see the screenmode and font requesters. You
can select any font and any mode. Any mode? Err, except EHB. Note that
these requesters are up, while you can do other things - completely
asynchronous. Nice! Yes, but it was certainly not while developing...
Huh? Asynchronous operations are a bit tricky to develope and not easy to
debug.
The two windows titled `Abgleich' (german for balance) are for changing the
attributes gamma, contrast, brightness, and color correction. The small
window `Ausschnitt' allows you to enter the position and dimension of a
rectangle, which is then used for viewing. All custom requesters have
keyboard control, adapt to the screen font, and operate asynchronously.
Note: This is not a manipulated snapshot! All windows are open at once!
Ok ok, I will believe you :)
When will TowerView be released?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Uhm, have a look at the screentitle. And? The version number is quite
small, isn't it? Yes, indeed. So do not expect it for a while, my `todo'
list is still full :) Sigh, wanna have it now! You could contact me to
become a beta tester, but currently, I have enough of them. I'd be happy
to help you beta test TowerView! If I need you, I will post a message in
the international news groups.
What features will TowerView have?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Apart from those already listed above, it will certainly allow you to save
your pictures, and much more... How much is `much'? Err, be patient.
What is required to run TowerView?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
An Amiga 4000, 18 megs of memory, and OS 3.1 :) Really??? Nah, being
serious, it will run on any Amiga having 2.1 system installed, but a
harddisk and a fast processor is highly recommended. Some features will
only be available with OS 3.0, such as datatypes support. What if I still
run 2.04? You would need the ReqTools 2.1 package to have a screenmode
requester, and you are stuck with an english user interface. Will it also
run with 1.3? Yes, but the functionality is restricted to a requester,
saying that you are not up to date :)
So what should I do now?
