VectorGraph, Radar, Lumpy Noise are copyright 1993, 94 by Paul Badger. They are shareware and are collectively part of the shareware package Garden Tools. Garden Tools may be posted to any server that is free and accessible to the public, as long as the readme file and Register program is posted with them. They may NOT be posted to any commercial on-line services and UNDER ON CIRCUMSTANCES MAY THEY BE POSTED TO AMERICA ONLINE. See below for CD-ROM distribution.
Garden Tools has the following shareware pricing.
$ U.S. 12 single user licenses for registration and updates by email (with filters as an attachment).
$ U.S. 17 single user licences for registration with new filters on floppy disks and updates by email.
A Site License costs $200 (roughly equal to 16 users) and covers allocations for your organization within a 160 kilometer radius of your site (100 miles).
Kagi Shareware collects my shareware fees. Payment is simple via the Register program that is included with the Garden Tools file. It prints an 1 page form that can be mailed, faxed or emailed. See the end of this file for details. When you will register Garden Tools, I will send you a new filter plus the latest updates of the filters in this package and any filters or updates that may have been added since you downloaded the program.

The filters are offered here in two forms. Math and No Math. They are compiled 68K code which has run fine (if a bit slowly) on all the power Macs I have tested it on. I hope to offer fat binary versions soon. The version you should install is governed by one (fairly simple) question. Do I have a 68k machine with a math coprocessor? If not, install the no-math versions.
VectorGraph, which appears in the Stylize menu, is a filter that maps the direction of shading. It does not respond at all to the lightness or darkness of an image but instead translates the direction of a pixel’s shading into a gray value from 0-255. Images processed with VectorGraph tend to have a pseudo 3D, metallic look. VectorGraph will work on an image with any number of channels but I think it looks best run on only one channel of a color image. Used on all three channels of color images, it tends to leave bright colored artifacts while much of the image is gray. One of the best color uses of VectorGraph I have found is to: Duplicate a layer. Run VectorGraph on the bottom version of the layer. Set the top version to color only. Merge layers if it looks like what you want.
VectorGraph is highly sensitive to high frequency information and you may achieve more desirable effects after running a fairly stiff Gaussian blur on the image. Try it both ways and compare. And don’t forget to register your shareware after that first big illustration job.
Radar, which appears in the Other menu, is a filter aimed at animators that will create the effect of radial sweep radar on an image. I’ve also found some use for the effect in my graphic design and fine art. It’s fairly intuitive and a little experimentation on a small area will quickly lead to the desired effect. John Knoll has written a small utility (called Rename?) that will rename frames so that the whole process could be animated to run overnight. Premier and After Effects probably something like this built in.
The values are floating point and are roughly centered around 1.00. Smaller values lead to lighter values and larger ones to darker values. One note on the math involved in the lookup table; it’s not linear so reversing the values for start gamma and end gamma (start gamma larger than end gamma) will lead to unpredictable results. It’s only possible to make the lookup table fade clockwise at this point. If anyone out there wants a checkbox to reverse the direction, send me mail.
Lumpy Noise, which appears in the Noise menu, is a filter I wrote to add noise with a desired grain size. It’s fairly intuitive and easy to learn with a little experimenting. The rule of thumb I use is that the Between Lumps value should be about half of the Lump Size value. This has nothing to do with the actual operation of the filter, it just keeps the processing times reasonable with Larger Lump size values. As with all filters that don’t have a preview, test the filter on a small selection first to tweak the settings, then undo the selection and run the filter on the larger image. Send in that registration and I'll get to the preview and some more cool filters that are in beta.
Note that the Color Depth and Color Divergence controls are highly interactive. This is not desirable, but making them more independent would slow things down more.
Garden Tools filters are copyright Paul Badger 1994. They may be posted to any sever that is free and accessible to the public. They may not be posted to commercial on-line services and UNDER NO CIRCUMSTANCES MAY THEY BE POSTED TO AMERICA ONLINE. I will normally grant permission for the filters to be included on non-profit CD-ROM collections but I would still like to know and would like to receive a free CD-ROM.
Registering Garden Tools
Garden Tools has the following shareware pricing.
$ U.S. 12 single user licenses for registration and updates by email (with filters as an attachment).
$ U.S. 17 single user licences for registration with new filters on floppy disks and updates by email.
A Site License costs $200 (roughly equal to 16 users) and covers allocations for your organization within a 160 kilometer radius of your site (100 miles). One big advantage of a Site License is that you do not need to keep track of how many people at your site are using the software. A World-Wide License costs $1200 and it covers all locations for your organization on the planet earth.
Paying for Garden Tools is fairly simple. Open the Register program that accompanies Garden Tools. Enter your name, your email address, and the number of single user licenses you desire for each program you wish to purchase (or Site or Word-Wide licenses). Save or Copy or Print the data from the Register program and send the data and payment to Kagi. More specifics on the Register program to follow. Kagi handles my payment processing.
If paying with Credit Card or First Virtual, you can email or fax the data to Kagi. Their email address is sales@kagi.com and their fax number is +1 510 652-6589. You can either Copy the data from Register and paste into the body of an email message or you can Save the data to a file and you can attach that file to an email message. There is no need to compress the data file, it's already pretty small. If you have a fax modem, just Print the data to the Kagi fax number.
Payments sent via email are processed within 3 to 4 days. You'll receive an email acknowledgment when it is processed. Payments sent via fax take up to 10 days and if you provide a correct Internet email address you will receive an email acknowledgment.
If you are paying with Cash or USD Check you should print the data using the Register application and send it to the address shown on the form, which is:
Kagi Shareware
1442-A Walnut Street #392-WV
Berkeley, California
94709-1405
USA
You can pay with a wide variety of cash from different countries but at present if you pay via check, it must be a check drawn in US Dollars. Kagi cannot accept checks in other currencies, the conversion rate for non-USD checks is around USD 15 per check and that is just not practical. If you have a purchasing department, you can enter all the data into the Register program and then select Invoice as your payment method. Print three copies of the form and send it to your accounts payable people. You might want to highlight the line that mentions that they must include a copy of the form with their payment. Kagi can not invoice your company, you need to act on my behalf and generate the invoice and handle all the paperwork on your end. Please do not fax or email payment forms that indicate Cash, Check or Invoice as the payment method.
As far as we know, there is still no technology to transfer physical objects via fax or email and without the payment, the form cannot be processed. Payments sent via postal mail take time to reach Kagi and then up to 10 days for processing. Again, if you include a correct email address, you'll hear from Kagi when the form is processed. If you do not have an email address, please enter your complete postal address. Please remember, we do not know what country you live in so please enter that into the postal address also.
