- Short: Preview of an upcoming picture viewer.
- Type: pix/illu

- 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?
