DotView is a Wheels-only (GEOS) program that can view 4-Bit files generated by GoDot and ConGo. dotView is a true switch-hitter, running in any mode, Wheels 64 - 40 column or Wheels 128 - 40/80 columns. For more information on the Wheels operating system itself, click on the CMDRKey.com WebSite link.
Glad you asked... The short explanation is that the file format simply has a bitmap of 320x200 resolution with 4-bit color depth, or more accurately, having a 4-bit brightness range. This is the native file format for GoDot, an image manipulation program for the Commodore 64. ConGo, a Windows 9x based program, can also manipulate these kind of files. I hope to go into detail at a later point about 4-bit files, but for now, its bitmap structure lends itself a lot of much needed flexibility in terms of image manipulation.

interesting - Show me some samples!I refer you to GoDot's English website. From this website, you can find out more information about GoDot itself, and how it works generally as an image manipulation program. The 4-bit file format is flexible enough to support nearly all of these graphics modes. Quite impressive, eh? For now, dotView currently only supports multi-color viewing of 4-bit files under the comfort of the Wheels operating system.
The renderizer routines are hard at work, decoding 4-Bit data...
which magically results in a very nice picture of a lady!
I'm
sold. How do I get it?Easy there on the wallet, thy Commodore GEOS Enthusiast. It's released as freeware, so that people who are currently using GoDot and ConGo can create 4-bit files and be assured that their creations can easily be viewed under the Wheels (GEOS) operating system. However, it is a BETA program and some warnings still apply:
This is a beta version. This is a disk-intensive program. While it only reads files and does not actually create or write any data to a disk device, there may be a possibility, however remote, that the dotView program will trash your disks, partitions, directories and files. I have taken every steps which I believe will promote the safety and integrity of every users' GEOS systems that it will eventually run under. You may be very well advised to try out the dotView program on partitions, directories and files that you can 'afford' to lose. The *old* caveat, even true during the heyday of Berkeley Softworks, is to always BACKUP your important files.
With this in mind, you agree to not to hold me, Arndt Dettke, and/or Maurice Randall liable for any losses that you may have incurred as the result of using the dotView program. The losses may include actual loss of file(s), loss of labor, loss of time, actual monetary losses and any possible loss that may arise from such use of the dotView program. Creating this dotView program is truly a labor of love for our Commodore machines and is not a money-making endeavor, and let's not tarnish it with any unnecessary unpleasantries.
If you accept the conditions and warnings that comes with the dotView program, please feel free to download the program and documentation. I thank you for your time and willingness to fully test out this program. I will look forward to your input, feedback, questions, comments, etc. which allows me to further refine and improve dotView for the Wheels (GEOS) operating system. Please help out by doing some of the following:
Posting bug reports. Please try to be specific as much as you can to help me pinpoint the problem and to fix it.
Give user interface suggestions. I may implement them or not.
Followups, comments, Replies, bug reports, etc. must be made either by private email to eyeth@videocam.net.au or Homestead@videocam.net.au. (preferred) Let's not clutter other emailing lists.
I
want to try out the program!Great! Before you download the program, dotView does have some requirements:
Wheels (GEOS) Operating System. Does not work in GEOS 64 or 128 v2.0 nor MegaPatch3 64 or 128 versions.
At least 64Kb of free RAM in any RAM expansion device. Please note that any ram expansion device supported by Wheels is just fine with dotView, as long as 64Kb can be made available. You may need to adjust the size of your ramdisk in order to free up this room.
40 column monitor. Yes, dotView can run in either 40 or 80 column modes of Wheels 64 and 128 operating modes. But, in order to view 4-Bit files in multicolor format, you need to have a 40 column monitor, or a 40/80 column monitor.
If you have all of that, then all you need to do is to download the following program, dotView B0.2 to your Commodore 8-bit computer setup. You need to run an unzip utility and a convert utility in order to convert this file back to the GEOS format. While you're at it, download and read the README file for the dotView B0.1 beta. It's a standard geoWrite v2.1 datafile and you need to use an unzip utility and a convert utility to convert this file back to the GEOS format.
Here's a ZIP archive which contains fifteen 4-bit files for you to try out with dotView. Just download it, dearchive its contents and run dotView on them. Also, Arndt Dettke will host a 4-bit file archive at the Godot's 4-Bit Archives. Here's a description of the 4-bit files in the archive: (Arndt Dettke contributed most of the comments here.)
mars - Was a standard multicolor demo (or game) image, don't know by whom.
amalienburg - A famous castle, also a multicolor image, took it from an old 64'er Mag disk.
tree - Not quite sure which image that is. (Looks like a tree and its reflection on a pond.)
time masters - A GoDot scan from an American book about the history of Science Fiction. Can look for the painter if you like. (This is Todd's personal favorite.)
rayhouse - Ditto.
buckrogers - And again: Ditto.
friends - This is a GoDot scan from a very old family newspaper of the 18th/early 19th century.
skyscrapers - Once was a Windows clipart photo.
spacewalk - This is famous. Don't know where I actually took it from.
superman - GoDot scan from a Comic Magazine.
tigress - Hehe, I got this picture as a GeoPaint image, and converted it for GoDot use with ConGo.
astro - This must be astronaut Bean on the moon (Apollo 17?), it's actually NASA copyrighted. Don't know where I got it from (that 64'er disk?).
eyes4u - Again a Windows clipart picture.
handball - This too.
street - And this too.
For starters, I hope to bring image manipulation and marry its power to the Wheels (GEOS) operating system. I hope to port GoDot to this platform and harness the power of image manipulation, all within the power, ease and comfort that the GEOS UI and operating system offers. No promises yet, but I need to build the conceptual framework for geoDot, a version of GoDot for the Wheels (GEOS) environment. Once I have all of this framework done, I'll be sure to announce my plans on the relevant Commodore communications channels.
Basically, geoDot would be a commercial product with a subscription plan. There are well over 200+ modules, loaders, savers, etc. for GoDot alone. That undertaking of converting these little programs would take a lot of time in integrating them into the conceptual framework of geoDot. Hence, the subscription plan. If everything follows to form, I hope to release several modules at a time, probably on a quarterly basis and also release a newsletter to go along with it. This newsletter would cover the modules that have been released and provide a tutorial of sorts on now to use these newly-created modules effectively.
This is how GoDot was largely introduced to its German-speaking audience, spread across over several issues of the 64'er magazine. Announcements will follow in due course when the conceptual framework of geoDot is done and a subscription plan can commence.
