- Limitations: Can only be used from the Workbench (start via Icon).
-
-
- Version 1.2 Notes
- -----------------
- Added full 8-bit RGB support (Hurray!).
- Added Iconify ("I" button) support.
- Added About ("?" button).
- Added support for "X" and "Y" icon tooltypes to determine position
- of PaletteTool window at startup.
- Corrected the Spread function's math to allow "smoother" spreads.
- PaletteTool will no longer open on a screen that supports less than
- 32 colors; a nice requester will pop up to remind you of this if you try.
- Fixed problem where original palette was not correctly restored upon
- quiting following certain types of Undo actions.
- Fixed problem where the currently selected color's RGB slider values were
- not correctly reset after an Undo action.
- All other features operate the same as in version 1.1.
-
-
- Version 1.1 Notes
- -----------------
- Added the Copy, Undo, and Spread capabilities.
- Added the "restore palette at exit" capability.
- All other features operate the same as in initial release version.
-
- The loading and unloading of the palettes at the beginning and end of
- cycling can lock up your Amiga for 1 second or so.
-
- DON'T PANIC IF THIS SHOULD HAPPEN! OK? Sorry for yelling!
-
-
- Why did I create PaletteTool?
- -----------------------------
- After deciding to take the plunge and buy an A4000 (which, by the way, is a
- fantastic machine!), I was disappointed in the current lack of applications
- which exploit the increased color capabilities of 3.0/AGA. I went about
- creating some simple, yet fun, graphics toys with would exploit the color
- modes above 16 (see my Fractal, Lyapunov Space, and Terrain uploads). Then
- I realized that these graphic toys needed some type of palette control, as
- Commodore saw fit to release a palette tool which would only handle the
- 8 Workbench colors. This need resulted in PaletteTool.
-
- I decided that is was much better to implement the palette control for
- these applications as a separate utility, rather than embed it within
- each one.
-
- NOTE that PaletteTool can be used to alter the color palette of ANY
- Workbench or Public Screen which supports at least 32 colors. It's
- functioning is not in any way dependant upon the presence of the Fractal,
- Lyapunov Space, or Terrain programs.
-
- IF YOU HAVE FRACTAL, LYAPUNOV SPACE, OR TERRAIN, PREPARE TO BE IMPRESSED BY
- WHAT COLOR CYCLING AND THE FULL 8-BIT RGB SUPPORT WILL DO FOR YOUR IMAGES!
-
-
-
- How do you use PaletteTool?
- ---------------------------
- Just click on the PaletteTool icon. PaletteTool will detect the number of
- colors available on the default Public Screen, and open it's window on this
- screen. Note that the Workbench screen is the standard default Public
- Screen.
-
- You can get PaletteTool to open on ANY public screen (like the AGA ones
- opened by Window Blender) by using you favorite public screen utility
- to change the default public screen. I use PublicScreenX to accomplish
- this.
-
-
- PaletteTool window description
- ------------------------------
- The PaletteTool window consists of the following items:
-
- 1) The current screen palette (color register display) is at the top of
- the window. This is where you select (using the pointer and the
- left-mouse-button):
-
- - the color to be modified by the Red/Grn/Blu sliders
- - the colors associated with Copy and Sprd (spread) actions.
-
- 2) A box which displays the currently selected color (on the middle-right
- side of the window).
-
- 3) Three color modification sliders, one each for the Red (Red),
- Green (Grn), and Blue (Blu) color components.
-
- 4) A "Show" button which flashes the currently selected color.
-
- 5) A "Sprd" button which allows spreads (gradients) between two selected
- color register. (Note that spread "from" color register must be prior
- to the "to" color register - more on this later.)
-
- 6) A "Copy" button which allows the copying of one color register's RGB
- values into another color register.
-
- 7) An "Undo" button which restores the palette colors to how they were
- prior to the immediately previous Copy or Sprd (spread) action.
-
- Note that I said "how they were prior to the immediately previous
- Copy or Sprd (spread) action". Don't get confused and think that
- the program is acting up when you do an Undo, and some individual
- color register mods you have made since the last Copy/Sprd get
- wiped out!
-
- IMPORTANT - Repeatedly selecting Undo will toggle the palette between
- where it was (before the last Copy/Spread) and where it
- is (before you selected Undo). Try this to get a better
- (or any) sense of what I'm trying to explain ;v).
-
- 8) A "Cycle" button which starts/stops the cycling of all colors in the
- palette.
-
- Note that all non-cycle-related sliders/buttons/etc. are disabled
- while cycling is in progress.
-
- 9) A "Spd" slider, which control the speed of the color cycling. Values
- range from 1 (= slowest) to 20 (= fastest).
-
- Note that the cycle speed control is active during cycling (i.e., you
- can change speeds which you are cycling).
-
- 10) A cycle-direction control.
-
- Forwd = Forward Cycle and Revrs = Reverse Cycle.
-
- Note that the cycle-direction control is active during cycling
- (i.e., you can change directions while you are cycling).
-
- 11) An "I" (Iconify) button, which changes the PaletteTool window into
- a single ("Open") button. Pressing the Open button will restore the
- PaletteTool window.
-
- 12) A "?" (About) button, which opens an info requestor.
-
-
- PaletteTool operation
- ----------------------
- You select a color for modification (or just viewing) by left-clicking
- on one of the colors in the palette display.
-
- This becomes the "active" color.
-
- The "currently selected color" box on the middle-right side of the window
- will change to show you the color you just picked.
-
- If you get confused as to which color you actually picked (which can easily
- happen with 256 colors!), pressing the "Show" button will flash the
- currently selected color.
-
- Once a color is selected, it's RGB components can be modified by using
- the three Red/Grn/Blu sliders.
-
-
- Color "spreads"
- --------------
- Color spreads between two palette colors is accomplished via the "Sprd"
- button. To perform a "spread":
-
- - first select the starting color
- - hit the "Sprd" button
- - then select the ending color
-
- All intermediate color registers will then be changed to a smooth
- gradient between the staring and ending colors.
-
- >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
- >> Note that spreads only work in the "positive color register <<
- >> direction". That is, the ending color must be physically to <<
- >> the right and/or down from the starting color. <<
- >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
-
-
- Color copying
- -------------
- The copying of a color from one register to another is accomplished via
- the "Copy" button. To perform a copy:
-
- - first select the color to be copied
- - hit the "Copy" button
- - then select the register where that
- color should be copied-to
-
- Note that unlike spreads, you can copy any color register to another one.
-
-
-
- About the palette display
- -------------------------
- The palette display is fixed in size. Therefore, the displayed size of
- each color in the palette decreases as the number of screen colors
- increases.
-
- The color registers are displayed in "row sequential form" from left-to-
- right and top-to-bottom.
-
- Therefore, the first row in the palette display consists of color registers
- 0, 1, 2, 3, 4, etc.
-
-
-
- Icon Tooltypes
- --------------
- X = <number> - The X-coordinate at which the PaletteTool window
- will initially open.
-
- Y = <number> - The Y-coordinate at which the PaletteTool window
- will initially open.
-
- If these tooltypes are not present, the PaletteTool window will open at
- coordinates X=10 Y=10.
-
-
-
- About the "protected screen colors"
- -----------------------------------
- It appears that the 8 colors used by the Workbench display (window borders,
- backgrounds, highlighting, etc.) are always assigned to the following color
- registers:
-
- 0,1,2,3 >and< the last four colors in the screen palette.
-
- PaletteTool will NOT allow you to select these 8 color registers.
-
- Additionally, color registers 17, 18 and 19 appear to be consistently
- reserved for the screen pointer.
-
- PaletteTool will NOT allow you to select these 3 color registers).
-
- **************************************************************************
- If you attempt to select one of these color register, nothing will happen.
- **************************************************************************
-
- In fact, if you are selecting the "to" color register for a Copy or Sprd
- (spread) action, the pending action will be cancelled.
-
- PaletteTool operates this way because I didn't want to able to screw up
- the colors which the system (or you for that matter) expect to remain
- unchanged.
-
- Note that the three pointer colors will also be skipped if you do a spread
- whose starting color register number is less than 17, and whose ending
- color register is greater than 19. This allow you to do spreads without
- having to worry about "clobbering" the pointer colors.
-
-
- Other considerations
- --------------------
- The user should exercise care when changing any color which another
- application on the screen may already be using. If you are uncertain
- about this, just use the "Show" button to flash the color. This
- will flash the color in the palette display as well as any other place
- that color register is employed.
-
- Additional note: For Workbench backdrop pictures (IFF ones), it appears
- that the Workbench allocates color registers at the high-end of the palette.
- Since, however, PaletteTool restores the palette when it exits, you should
- be able to return to "normal".
