- NAME
- WBVerlauf - Create background copper list on the Workbench screen
-
- SYNOPSIS
- WBVerlauf Startcolor,Endcolor,ColorNumber/N,Step/N,Info/S
-
- The AGA chipset and Kickstart 3.0 are required.
- All options are available from icon tooltypes or as command line
- arguments.
-
- DESCRIPTION
- WBVerlauf lets you create nice color effects for a selectable
- pen color number on the Workbench screen, using the whole
- 16 million color range of the AGA chips.
- It works in Workbench and shell environments, and can be put in the
- WBStartup drawer.
- You specify the color of the first and the last line of the screen,
- and WBVerlauf will make a smooth color change by setting a new
- color value on every scanline.
- If started from a shell, you can hit Ctrl-C or use the "Break"
- command to quit. If started from Workbench, double-clicking the
- program icon again forces the running copy to self-terminate.
-
- Example: I have an 8 color Workbench, and I set the Workbench's
- background color to color 4 (using the WBPattern prefs
- editor). Then I set the COLORNUMBER tooltype to 4, so
- only the Workbench's color gets changed by WBVerlauf.
- This looks very nice (the icon is designed for this case).
-
- INPUTS
- STARTCOLOR - A six digit hexadecimal number specifying the
- color of the first line of the screen. The first
- two digits select the red level, the next two
- digits the green and the last two digits the blue
- level. So a startcolor of 0xF765E3 would give you
- a nice pink (0xF7 for red, 0x65 for green and
- 0xE3 for blue; 00 is dark and FF is bright).
-
- ENDCOLOR - A six digit hexadecimal number specifying the
- color of the last line of the screen.
-
- COLORNUMBER/N - Pen number of the color to change. A value of
- 0 means background color, 1 is normally the
- text color, 3 is for window borders, etc.
- Must be in the range of 0 to 255.
-
- STEP/N - Number of lines between color changes. Defaults
- to 1. If you have a slow processor, you may wish
- to set this to a higher value, so the screens
- will scroll faster.
-
- INFO/S - Display a short info message and return to shell
-
- WARNING
- This program makes use of undocumented hardware components of the
- AGA chips, and is not programmed according to Commodore rules.
- It will not work with future hardware or software versions.
- You must NOT use this code in professional applications.
