Gradient and bitmap fills

The Gradient Tool lets you draw a simple color gradient, solid or bitmap fill across your object. The created fill path can be edited directly on the object to introduce more than two colors along the gradient path, introduce opacity, reposition added colors or control color transitions. You can also apply a more complex gradient via a Gradient Editor.

Gradient Tool To apply a gradient:
  1. Select an object.
  2. Select the Gradient Tool from the Tools panel.
  3. From the context toolbar, select either 'Stroke' or 'Fill' from the Context pop-up menu.
  4. From the context toolbar, select a fill type from the Type pop-up menu.
  5. Drag the cursor across the object's stroke or fill depending on what you selected previously.
To create a bitmap fill:
  1. Use the Move Tool to select an object.
  2. Select the Gradient Tool.
  3. Do one of the following:
    • From your Finder window, drag the file of choice and drop it onto either the Swatches panel, Color panel or the Foreground/Background color selector.
    • From your Explorer window, drag the file of choice and drop it onto either the Swatches panel, Co lour panel or the Foreground/Background color selector.
    • From the Assets panel, click an asset, e.g. a texture, shape or other.
    • From the Stock panel, click one of the photos from your search results.
  4. Use the context toolbar settings and the tool's nodes to modify the fill as required.
To modify a bitmap fill:
  1. With the Gradient Tool active, make a selection.
  2. On the context toolbar, click Rotate gradient to change the orientation of the fill at 90° clockwise intervals.
  3. Enable Maintain aspect ratio to ensure the bitmap fill is not stretched or squashed when edited.
  4. Set the Extend and Quality options as desired. The former option controls how the tile that makes up the bitmap is presented; the latter how the bitmap fill is resampled on object resize.
  5. Check Scale with object to allow for stretching or shrinking of the bitmap fill while resizing. Leave it unchecked to ensure stretching or shrinking isn't taking place thus preserving the texture of the image.
To modify a gradient (directly on an object):

With the Gradient Tool selected, click an object with a gradient fill applied and then do any of the following:

To modify a gradient (via the tool's context toolbar):
  1. With the Gradient Tool selected, click an object.
  2. Deselect any selected stops.
  3. From the context toolbar, select the color swatch.
  4. Click the Gradient option which lets you modify your gradient using the following settings:
    • Type—determines the gradient type (linear, elliptical, etc.) via a pop-up menu.
    • Position—controls the position of the stop along the gradient from left (0%) to right (100%), with 50% representing the central point.
    • Mid Point—adjusts the spread of colors between the selected color stop and the stop to its right.
    • Color—click the color swatch to display a pop-up panel where you can modify the selected stop's color (including noise value).
    • Opacity—controls how see-through the stop is. 100% represents fully opaque, 0% represents fully transparent.
    • Insert—adds a new stop between a selected stop and the stop to its right. The stop adopts the color at its new position.
    • Copy—duplicates the selected stop, positioning it between the selected stop and the stop to its right.
    • Delete—removes the selected stop from the gradient.
    • Reverse—the gradient is reversed, i.e. like a mirror image.

Scaling

Scaling bitmap fills

It is possible to rescale a bitmap fill by either restricting or allowing for the bitmap fill to grow or shrink when transforming, depending on the desired effect. One benefit here is that it is possible to leave the bitmap image and its texture unaffected by shrinking or stretching.

Transforming objects with linear or radial gradient fills

When you scale or shear an object with a linear, radial or conical gradient applied, the gradient will automatically reapply itself to fit the modified object's new shape. For shearing, dashed correction paths are applied to the gradient to indicate the gradient transformation.

The paths can be edited to control the shear and scale on the fill if needed—the path and stop can also be removed to ignore the gradient transform if needed.

This is also important when transforming two-dimensional objects onto an isometric grid plane as the gradient also needs to be intelligently transformed onto the plane, along with the shape's outline. On the transformed object, a dashed correction path is automatically applied as before.
