Re: Palette Colors

[User (Legacy)]

Thanks for the pie chart idea.  It may work.

If not, do you or anyone else know the format in the registry of the

palettes?  The actual colors do not start at the very top..there appears to

be some sort of a header in there as they all match to a certain extent...

Thanks,

Abe

I can tell you the palettes are stored in the registry:

[HKEY_LOCAL_MACHINE\Software\Software FX, Inc.\Chart FX\Palettes]

They are stored in Hex numbers that's a bit daunting (but not impossible) to

decode.  Basicly RGB(R,G, values stored in hex format.

Lots easier to create a pie chart with 49 sections and for each palette loop

through the points and save off the color value in a Color Table

Fields like PALETTENAME, POSITION, COLORVALUE.

Do this with a Pie chart (example in VBA, adjust for your purpose/platform):

   For i = 0 To nPoints - 1

      Debug.Print ChartFX1.Color(i)

   Next

First 4 points of various Palettes:

"ChartFX 3.0"

  65280 (Green)

 16711680 (Blue)

 255 (Red)

 16711935 (Violet)

"Nature"

 12638144

 11593903

 10535071

 9429135

"Electric Fire"

 3129599

 3117296

 48127
