Gradient Editor Thumbnail Image Window

Gradient Editor Window
Gradient Editor Window
Resizing

The thumbnail image window can be resized with the mouse at the bottom-right corner.

Quicklook - Seeing a bigger view of the fractal

Click on the thumbnail image to make it the key window. Press spacebar to open the large quicklook view window. Press spacebar again to close it.

Drag & Drop

Dragging a flame file on top of the thumbnail will cause the file to be opened in another Preview window. Click hold the mouse on the window’s image until a small thumbnail appears. Drag this onto a finder window or Desktop to copy the flame fractal document to that location.

Current Color Gradient

Shows the expanded 256 index color gradient created from the color stop settings. Caret shows the location of the currently selected color stop.

New ! The color stop locations can either be equidistant or they can be at irregular intervals.

Color Stops Panel

Color Stop Table
Color Stop Table
Color Stop Table

The color stop table shows all of the defined color stops for the gradient. 2 or more color stops are required.

Color
The RGB color for this stop.
Location
The color stop index value.

Color Stops panel buttons

+
Add a new color stop.
-
Delete the selected color stop.
Up
Moves the selected color stop up in the color stop list.
Down
Moves the selected color stop down in the color stop list.
Scramble
Randomly scrambles the order of the color stop values.
CandyStripe
For gradients with few color stops, changes the smooth gradients between color stop locations to a candy cane appearance.

Selected Color Stop Panel

Selected Color Stop Panel

The color stop table shows all of the defined color stops for the gradient. 2 or more color stops are required.

Red
The red RGB color value for this stop.
Green
The green RGB color value for this stop.
Blue
The blue RGB color value for this stop.
Location
The color stop’s position between 0 and 100%.
Hue
The hue value for this stop.
Saturation
The saturation value for this stop.
Brightness
The brightness value for this stop.
Color well
Click on this to bring up Mac color selection panel.
HTML color code
An editable HTML hexadecimal color code representation for this stop.

Modify Color Gradient By Panel

Modify Color Gradient Panel Modify Color Gradient Open Panel

A slider allows you to modify the entire color gradient by dragging the slider to a new location.

A pop-up menu button allows you to select what the slider does to the individual color gradient color stop values.

Rotate
Rotates all of the color stops’ location index values.
Hue
Modifies the hue value for each color stop.
Saturation
Modifies the saturation value for each color stop.
Brightness
Modifies the brightness value for each color stop.
Red
Modifies the red RGB value for each color stop.
Green
Modifies the green RGB value for each color stop.
Blue
Modifies the blue RGB value for each color stop.
Blur
Blends adjacent color stop RGB values together.
Frequency
Divides entire color gradient range into smaller chunks and repeats the smaller chunks.

Invert Button
Inverts all of the colors in the color gradient.

Reverse Button
Reverses the index order of all of the colors in the color gradient.

Flame Background Color well
Click on this to bring up Mac color selection panel for the fractal’s background color. Beside the color well is the background color’s HTML hexadecimal color code. This color code is editable.

Color Curves Button
See next section.

Supplemental Color Curves

New ! Fractal Architect 4 fractals can utilize supplemental color curves. These operate much like the color curve editors in popular photo editor apps where you can manipulate the separate RGB, Red, Green, and Blue color curves.

Click the mouse on top of the color curve to insert a new control point, then drag it to shape the curve.

If the mouse is clicked close to an existing control point, it will be selected so you can drag it with the mouse to shape the curve.

These color curves are unrelated to the curves shown for Smooth palette mode gradients.

Color Curves Example
Color Curves Example
RGB, Red, Blue, and Green Curve Selector
Selects which color curve to show in the color curve editor.
Reset Curve
Resets the curve shown to simple straight line.
Reset All Curves
Resets all 4 curves to simple straight line.
Apply To Background
If selected, applies the color curves to the fractal’s background color too.
Copy
Copy the color curves definition to the clipboard.
Paste
Paste the color curves definition from the clipboard.

Palette Mode

Step
Step mode.
Linear
Linearly interpolation of color stops mode.
Smooth
New ! Spline interpolation of color stops.
This uses the same color stops as the other modes, but does spline interpolation of the color gradient and will show a different looking gradient than the other 2 modes.
Spline interpolation will give the smoothest gradient.

Hue, Saturation, Luminance Display

New ! The color gradient display, only for Smooth palette mode, can show the spline smoothed Hue, Saturation, and Luminance curves superimposed above the color gradient.

These curves might be clipped at either 0% or 100%. Adjust the nearby color stops manually until the curves become smooth, if you want to fix the curve clipping.

Synchronize with Preview window panel

Synchronize with Preview Panel
Synchronize with Preview Panel

For performance reasons, gradient changes cause an immediate re-rendering of just the editor thumbnail window, not the fractal preview window.

This behavior can be overridden with the switch settings in this panel.

Auto-Apply to Preview Switch
When set to On, forces rerenders to the Preview window too.

Load from Fractal Preview Button
Loads the color gradient from the one used to render the Preview window.

Apply to Fractal & Others Button
Applies the current color gradient to the fractal itself and re-renders the Preview window and other thumbnails of that fractal.

Undo/Redo Buttons
Allows you to undo color gradient changes made to the fractal itself. Just the Preview window is affected.
