This requester will help you change the default color palette of the screen
JcGraph is on using both RGB and HSV color model. At the top, there is some
standard intuition gadget (ie Close, Depth, etc...) that need not to be
documented here (refer to your user manual). The first, leftmost gadget you
will see is a recessed box that shows the color actually active. Click on any
color at the bottom of the requester and you will it changed accordingly.
Right of this gadget is marked vertically with letters RGB followed by three
sliders. It means that you are in the RGB model an that every one of the Red,
Green and Blue component of the active color can be modified with the
appropriate slider at right. Note that values, ranging from 0 to 15,
representing the amount of each RGB component are written at slider's right.
This color palette selector also offers you the possibility to work with
the HSL color model (meaning Hue, Saturation and Luminance), you just have
to click on the area marked RGB to see it changed to HSL, click back on HSL
to return to the RGB color model.
The big, full-color, rectangular gadget at the bottom of the requester is
quite self-explanatory; it helps you choose the color you want to be activated.
Next to it, at right, is a kluster of gadget that are decribed here:
COPY: Copy the active color on to another that you will choose after.
RANGE: Will create a range between two color that you will specify.
OK: Close the requester and keep your modification
CANCEL: Cancel all the change you may have done to the color palette.
The menu:
Open...: Load a color palette previously saved. Note that because it is
IFF format, JcGraph can find color palette in almost any IFF file that
as CMAP chunk (ie Preferences palette, DR2D file, ILBM, Imagine file,
etc...), this is handy.
Save As...: This will save you color palette to a file wich will then be accesible
with any IFF CMAP palette reader. (Note that some palette reader
make some false assumption about IFF and may have trouble loading
JcGraph's IFF file, notabily FreePaint and Commodore's own Palette
preferences!!!)
Copy: Copy the entire color palette to the Clipboard.
Paste: Paste the entire color palette from the Clipboard. (note: that's a
shame that so few program do that :-()
Note that pressing ESC on the keyboard or closing the window will have the
same effect as clicking on CANCEL gadget.
