- A Spline Screen Blanker Commodity

-
- Tom Rokicki's Mackie is one of the most well-known and most beautiful
- utilities for the Amiga. It has two separate functionalities: it's a
- blanker which draws wonderful splines, and a powerful hot-key manager.
-
- What I did was taking out the spline code from the original Mackie sources
- and encapsulate it in a standard Commodity (of course, this means someone
- else will have to port the hot-key part...).
-
- Commodities are the new way, designed by Commodore, by which all special
- utilities like mouse accelerators, macro expanders etc. should be
- designed. This standard, available *only* under 2.0, allows easy
- and customizable control of the interaction of different utilities.
- This means, of course, that Spliner will work only under 2.0.
-
- In the process of moving to 2.0, some new features were added, namely
- programmable pattern change timeout, and the possibily to open the blank
- screen in *any* of the modes available on your Amiga.
-
- For the generic use of a Commodity, please refer to the 2.0 manual.
- Spliner will (more or less) work just like the screen blanker supplied on
- the Workbench 2.0 disk.
-
- If you activate Spliner by double-clicking on its icon, you will see a
- little window popping up. The meaning of the HIDE and QUIT gadgets and
- menu items are identical to the ones of Commodore's blanker. The TIMEOUT
- gadget lets you set the number of seconds after which the screen is
- blanked, while the gadget CHANGE lets you set the time after which the
- drawing pattern is changed. Set this to zero to go psychedelic. 8^) Both
- default to 60. The CYCLE COLORS checkbox allows you to enable/disable the
- color cycling (mainly for special screen modes such as 2024_10Hz).
-
- The list displayed on the right represents all video modes installed on
- your system. This list could also include some modes that aren't really
- displayable on your Amiga, but no harm can be done. You can click on any
- display mode in order to force Spliner to use that kind of display when
- blanking the screen.
-
- There are four extra tooltypes, TIMEOUT, CHANGE, DISPLAY and CYCLE that
- act just like the corresponding gadgets. Note that the name you set
- DISPLAY to must be an exact copy of the name appearing in the window list
- (up to lower/upper casing). For instance, DISPLAY=PAL:Lores-Interlaced. If
- you have a PAL (resp. NTSC) Amiga and you have a real MultiSync monitor,
- you can even add the NTSC (resp. PAL) monitor to your system and open the
- blank screen with another video frequency! This has no usefulness at all,
- but it's amusing. The CYCLE tooltype can of course be set to ON or OFF.
-
- In order to start Spliner at power-up, the best thing is to move its icon
- into the WBStartup drawer, and to set its tooltypes to the desired values.
- Don't forget to add the DONOTWAIT tooltype, too. You'd probably also want
- to set CX_POPUP=NO.
-
- IMPORTANT NOTICE: Some people think that terrific blankers steal CPU time.
- This is not the case with Spliner. If a task is using the CPU, Spliner will
- stop drawing. If in particular your application has a hi-res multi-color
- screen, the presence of the blank screen will actually speed up whatever
- the Amiga is doing, by lessening DMA contention.
