-
- The Color Editor is a tool for use by DKBTrace users to preview and
- design colors for inclusion in their data files. (It also gave me an
- opportunity to play around a bit during working hours while IBM was
- busy trying (unsucessfully) to recover our LAN server drives!)
- As you will see, I got a bit carried away with GUI interfaces during
- this project. No, this is NOT an Amiga port.
-
-
- Environment / Commandline options:
- ----------------------------------
- TCE looks for your COLORS.DAT file in the current working directory
- unless you tell it to look elsewhere.
- There are two ways in which you can do this:
-
- 1) You can set an evironment variable DKB to the path to COLORS.DAT
- SET DKB=C:\DKB\DATA\COLORS.DAT
-
- - or -
-
- 2) You can tell TCE on the commandline:
- TCE c:\dkb\data\color.dat
- - or -
- TCE mycolors.dat
-
-
- How it works:
- -------------
- 1) Upon startup, the program will pause for a few seconds while it
- generates a gray palette and paints the preview image.
-
- 2) If you didn't specify a color data file, and TCE can't find one
- in the current directory, it will ask you for the path and name
- of your color file.
-
- 3) Viewing COLORS.DAT:
- Once the color file has been loaded, TCE will display the first
- color in your file. You can scroll through the file with your
- up/down arrow keys. Press "P" or "V" to project the color onto
- the preview image.
-
- 4) Keys:
-
- R G or B (Upper Case) Increase Red, Green, or Blue.
- r g or b (Lower Case) Decrease Red, Green, or Blue.
- D or d Darken the current color.
- L or l Lighten the current color.
- C or c Clear all values to white,gray,or black.
- V,v,P,p PreView color on a shaded sphere.
- S,s,W or w Save/Write the color to COLORS.DAT
- + Toggle Fast/Slow step rate.
- ESC Quit the program.
- F Specify Input/Output filenames.
-
- Editing/Creating Colors:
- ------------------------
- Existing COLORS.DAT color declarations will NEVER be over-written by TCE.
- You can, however, scroll to a color in the file and then modify it,
- and save it with a new name (or the same name, for that matter. See
- section below about saving colors).
-
-
- Fine / Course Tuning:
- -----------------------
- On startup, changes are stepped by +/- 0.01, so you can make very fine
- changes in hue or saturation, but at the same time, it may seem sometimes
- like nothing is happening. Pressing the + key will toggle to a fast mode
- where changes are stepped +/- 0.1. A panel in the lower right displays
- either "Fast" or "Slow" to show which mode you are currently using.
-
-
- Saving a color (S,s,W, or w keys)
- -----------------------
- Pressing the "S" or "W" key puts you into save mode. You will be prompted
- for a descriptive name for the new color. Pressing <ENTER> without
- entering a name will abort the save operation and you will be returned
- to the color editor.
-
- Color names are NOT checked for duplicity, but at the same time,
- colors are never over-written. If you do have duplicate color names,
- I believe DKB will use the last declared definition. There is no delete
- function, so you will have to use a text editor to remove unwanted
- color declarations. There is a limit to the number of DECLARATIONS that
- DKB can use, so you may wish to store new colors to a separate COLORS.DAT
- file until you want to use them.
-
- Spherical Preview (V,v,P or p keys)
- -----------------
- This is, admittedly, a hack. It's sorta slow generating the palette,
- and the way I draw the sphere leaves a bit to be desired, and it is
- only an approximation of the way the color will look on a rendered
- object, but it got the product out of the door and into your hands.
- (Besides, it's really kinda neat!).
-
-
- That's about it. Pretty easy, huh? But I think you'll find it helpful
- when you're looking for that illusive color for bread dough!
-
-
- What's new:
-
- Version 1.01
-
- Doesn't really DO anything new, just what it does, it does better.
-
- Better palette scaling for the preview window. Nicer preview
- image, too, with a sky and a shaded background. Also, the
- preview image now is drawn only once, at load time.
-
- This gives two benefits:
-
- 1) You only have to wait once for it to draw.
- 2) Since the palette is not updated in the image until you
- press "Preview", you can compare a previously previewed color
- against one in the window.
-
- Now if only I can come up with a quicker palette loader!
- (I'm looking into it)
-
- The original release allowed you to specify a PATH to your
- color file, either on the command line or with a DOS environment
- variable "DKB". Both methods still work, but must have the
- filename, too. This is because DKB Version 2.10 looks for
- a file named COLORS.DAT, where earlier versions looked only
- for COLOR.DAT (singular).
-
- But wait... it gets better!
- You can now specify from within the program the name of your
- input file and optionally a name for a separate output file.
- What used to be the Help button (who needs help when you have
- a document file, right?) is now the "Files" button. Press "F"
- and you will be asked if you wish to specify an Input file or
- an Output file. Pressing <Enter> will abort the process.
