Palette Editor
Adjusting the palette is done in the palette editor. It allows you to adjust the colors, to choose the type of interpolation and to choose the color model. Several preset palettes are provided with ChaosPro, so you should already have some coloring schemes for your fractals. The palette editor looks as follows:
As you can see, there are three display fields, one for each color component (red, green, blue). By looking at a color component you can easily identify the different knots and the interpolation line.
- You can change the colors by dragging knots with the mouse. Your changes are made in realtime, so you will see the effect of dragging a knot to another location even during your drag operation.
- You can add a knot by double clicking into the displayfield onto the position where you would like the knot to be added.
- You can delete a knot by selecting it (clicking onto it using the mouse) and then pressing the DEL key or the BACKSPACE key on your keyboard.
- You can perform drag or delete operations on multiple knots at the same time by using “multiselect”: Simply click into the displayfield, hold down the mouse key and move the mouse around: A selection rectangle will appear. Drag it, so it covers the knots you’d like to be selected. While holding down the SHIFT key on your keyboard you then can preserve the selection and drag all selected knots around.
Holding down the SHIFT key on the keyboard will generally preserve the selection state of the knots. So you can multiselect knots by holding down the SHIFT key and selecting each knot separately: It will then be added to the current selection list.
To the left and right side of each displayfield there is a so called “color simulator”: It shows you what would happen if you would move the current knot up or down.
Below the displayfields there is the offset slider: This slider allows you to displace the palette.
And below the offset slider at the left edge of the palette editor there is the color selector: It displays the current color. By clicking onto the filled circle another window will open which allows you to choose a color using the HSL color wheel.
The items beneath the color selector let you view or manually adjust the color values.
And the last item in the palette editor is the Smooth checkbox. If it is not checked, then the knots are interpolated using linear interpolation. Otherwise the knots are interpolated using a limited cubic spline (i.e. a smooth curve).
