- The DESQview Palette Program
-
- A. OVERVIEW
-
- EGA cards and VGA cards in EGA emulation at any given time can
- display 16 colors out of a palette of 256 possible selections. In
- order to achieve a specific "look", many applications that are
- designed to run on these displays, modify the palette from the
- original 16 color default set by the EGA or VGA BIOS.
-
- When you run a program in DESQview that has modified the palette,
- the program will appear in its normal color scheme when it is run
- in the foreground. When you hit the DESQview key to switch to
- another window, DESQview will shift the palette so that it brings
- up its own menu using the palette that was current when DESQview
- was started.
-
- The DESQview Palette program, that is included on the DESQview 2.2
- diskette, is designed to allow the users to manage the setting of
- the EGA and VGA palette while running in DESQview. This has a
- possible two-fold purpose: Either to allow you to modify the
- palette of DESQview to a selection you particularly like, or to
- match the DESQview palette with that of an application you commonly
- use so that DESQview will not have to readjust the palette when you
- invoke the DESQview menu over an application that has modified the
- palette from the BIOS default.
-
-
- B. OPERATION
-
- 1. Palette Bar - When the palette program first comes up, you will
- see two rows of 8 colored blocks. These sixteen colors,
- represent the currently selected 16 color palette. Using the
- Palette Bar, you can make specific modifications to anyone or
- all or the 16 standard colors. For example, on some systems,
- the low-lit color number 6 appears to be yellow, although IBM
- defines this as brown. Using DVPALET, you may be able to
- modify the palette to be closer to what IBM defines (or away
- from it if you don't particularly like the brown color). Once
- you have modified the palette to your liking, you have the
- option of saving the changes to a file, so that they can be
- reloaded anytime you like (even as the default, when DESQview
- comes up).
-
- To operate on the Palette Bar:
-
- a) Move around the palette bar using the right and left arrow
- keys.
-
- b) Move the up and down arrows to select the primary color that
- you want to add or subtract from.
-
- c) Use the plus and minus keys to add or subtract the amount of
- the selected primary color from the current selection on the
- Palette Bar.
-
- 2. Options
-
- a) Blink Enable - Disables a program's ability to set a
- blinking attribute. Characters that would normally blink
- are changed to show a highlighted foreground and background.
-
- b) Copy to Hi-Colors - Copies low intensity colors to the high
- intensity colors. This effectively eliminates selection of
- high-intensity colors. If you select this option and don't
- like it, you can restore the highlighted colors by selecting
- "Restore" and "Original" from the menu.
-
- c) Restore Palette
- 1) Original Palette - Sets the palette to the one that was
- current at the time the DESQview Palette program was
- started.
-
- 2) Bios Default Palette - Sets the palette to the default as
- defined by the BIOS in your EGA or VGA card. This is the
- selection to choose if, in tinkering with the palette,
- you get your colors so out of whack you wish to reset the
- default. Selecting this option and then saving the
- palette to the default file name will reset your video
- card's default palette when in DESQview.
-
- 3) Windows Compatible - This selection sets DESQview's
- palette to the same palette used by Microsoft Windows or
- Windows based applications. When this is set, hitting
- the DESQview key will not result in a palette change for
- the underlying Windows application.
-
- 4) GEM Compatible - This selection sets DESQview's palette
- to the same palette used by Digital Research's GEM and
- GEM applications. When this is set, hitting the DESQview
- key will not result in a palette change for the
- underlying GEM application.
-
- 5) Enhanced Palette - This selection sets the current
- palette to a combination the author of the DESQview
- Palette found pleasing (at least on his system).
-
- d) Load Palette - Loads a preconfigured palette from a saved
- palette file. When you select this item, you are presented
- with a field into which you may type a file name. The
- default file name is DVSETUP.DV. If the palette is loaded
- from the default, the palette that DESQview originally came
- up with will be set. By entering the name of a previously
- saved palette file, you can load a custom palette you have
- created.
-
- e) Save Palette - Allows you to save the current palette.
- When you select this item, you are presented with a field
- into which you may type a file name. The default file name
- is DVSETUP.DV. If the palette is saved to the default, this
- palette will be set each time DESQview is started.
- Alternate palette sets may be saved under other file names
- and loaded with the Load Palette command.
-
- f) Quit - Exits the DESQview Palette program. DESQview will
- retain the current palette until you quit DESQview or modify
- the palette again.
-
- C. SUGGESTED ENHANCEMENTS
-
- If you have several palette settings that you have configured and
- saved into palette files, one enhancement would be to configure a
- series of DESQview scripts of macros that automatically loads
- these custom palettes. Since the DESQview Palette program does
- not make use of the Function keys, the keys F1 through F10 might
- be suitable for this purpose.
