Vector
Studio 2.0 : Sampler Tools
(1) Color (2) Transparency (3) Weight (4) Weighted Transform Tools
The basic idea behind Sampler Tools is to set up simple rules for editing
multiple objects. For example, if you want to lighten all of the colors
in a particular part of your drawing, all you do is select those objects, choose
the Color Tool, and adjust a single lightness slider. This type of adjustment
is referred to as Tuning ().
Sampler Tools also includes the notion of sampling, or using one object to control
the appearance of other objects. For example, with Image Sampling (),
you can use a scan or painted image to re-color a collection of objects. (Note
that image sampling is not confined to using a raster; any Illustrator object
will work as an image source). Once again, the interaction is very simple: select
the objects that you want to re-colorize and then an object to use as a sample.
For each object selected, the color at that position in the image is sampled
and used to change the fill and stroke of the selection. Another sampling option
in Sampler Tools is Gradient Sampling (),
which works like image sampling. You simply drag out a gradient, and the colors
of the gradient are used to re-color the current selections.
In the following
examples we will show you the various Sampler Tools and how to use them.
Here's
an animation of an artistic rendering of a mango. The three basic steps
are: Step 1) Place an object in the document for reference. The mango shown was created in Illustrator using the Retouch Brushes, but you can use any object you desire. Step 2) Draw out the strokes with Paintbrush tool in Illustrator. Note that to avoid modifying the selected brush strokes, turn the "Keep Selected" option off in the Paintbrush preferences. (Double-click on the paintbrush tool icon to access the options). Step 3) With the Color Tool, use the Image Sampling method to colorize the strokes. |
This example
shows how you can create illustrations that have a painterly feel to them by
using the Paintbrush with an Art brush applied. Like the mango animation above,
the strokes are drawn out (middle picture below) and the original image (left
picture) is sampled to re-colorize the strokes in the finished drawing (right
picture).
Since the resulting flower remains vector-based, you can easily modify
any attributes of the strokes. Changing the path's brush, transparency
or stroke thickness lets you create an unlimited variety of drawings
rich in color and detail. Also, since you layout the brush strokes, you have
complete control over the character and contours of paths, something impossible
with simple filters.
The following
designs were all created with the same set of strokes with various brush styles
applied.
This is another
example done using the same technique as shown above. Once again, the only difference
between these different drawings is the brush style - a single click on the
brush palette!
In addition
to strokes, you can also apply image sampling to filled paths. In this
example Illustrator's Hatch Effects filter (Filter>Pen & Ink>Hatch Effect) was
used to create a collection of paths. (Note that you must unmask and ungroup
the result of the Hatch Effects filter). The second picture was made from the
first picture by distorting the paths with Liquify's Wrinkle Tool, and changing
the mix mode in the transparency palette to multiply.
Not only
does this tool work well on paths, but it also works beautifully with gradient
mesh objects! In this example, we create a bunch of grapes by making multiple
copies of a gradient mesh and using Image Sampling to copy the colors from the
scan of the grapes to the gradient mesh vertex colors.
After performing
the image sampling, you can vary all the colors of the mesh with the Tuning
variation of the Color Tool. The Tuning mode supports adjustment in the HSB,
CMYK, and RGB color spaces. In this example, a Hue shift is used.
The Tuning mode features an interactive slider that shows up directly
on the artboard, rather than in a dialog, allowing you to focus on your
design. However, if you need them, dialogs with all the options are a mouse
click away. Colors can be randomized in all three interaction methods
as an option in the dialogs.
So far we
have only explained two variations of the Color tool: Tuning ()
and Image sampling ().
We will now describe the third method called Gradient Sampling ().
The following animation shows how you can sample ()
the gradient from the document (holding Shift with Color Tool) and easily re-color
the collection of circles. You can also see that Gradient sampling comes with
two different interactions: Linear and Radial.
Similar to
the Color Tool, the Transparency Tool comes packed with three
different interactions: Tuning, Image, and Gradient methods. Like the color
image sampling, you can use an image to define opacity values. The Tuning variation
comes in handy when you want to change many objects at the same time: just make
a selection and then drag with the Transparency Tool. The Gradient sampling
method, as shown below, works beautifully when you want to control various objects
at the same time!
Sampler Tools
(as well as Retouch Brushes) allows you to assign weights to objects,
which can attenuate or accentuate the application of a tool. Assigning weights
to objects is a very simple task, but can be a very powerful tool. Take
a lightening example: Suppose you do not want to uniformly lighten colors in
the selections (with the Color tool), but rather you want them to get progressively
lighter from left to right. With Sampler Tools, you can assign lower weights
to the left and higher weights to the right. The objects with the higher weights
will be affected more dramatically by the lightening. Just like the Color and
Transparency Tools, the Weight Tool allows assignment of weights in three
different interactions: Tuning, Image, and Gradient sampling. Weights can be
randomized in all three interaction methods as an option in the dialogs.
The Weighted Transform Tool also utilizes the weight values. The default behavior, called global transform, of the weighted transform tool is to scale, rotate, or translate all selected objects relative to the same position on the page, while honoring whatever weights have been assigned to them. A variant of the tool, called local transform, allows transformations to be done relative to the position of each selected object. To access this variant, Shift-click on any of the currently selected objects. You can then manipulate the transform handles of that object and all of the other objects will follow suit. .
In the following
animation we are performing a local rotation with weights distributed from the
center of the selection. In the first frame, you can see the transform handles
drawn at the center. This represents a local transformation. Scale and translation
can also be done.
Sampler Tools is tightly integrated into Illustrator's working environment. As with all of Vector Studio 2.0 tools, Sampler Tools integrates Smart Guides and Snap to Grid features, giving you better control and precision in editing your designs. To make the tools even more useful, all of our tools come with shortcut keys so you can spend more time with your design and less time changing controls.
For additional convenience, Sampler Tools does not require a selection. If there is no selection on mouse down, all the objects on the current layer are used. It's a handy feature not only because you don't have to make a selection, but also because the "blue" selection outlines can distort the perception of colors.
Sampler Tool is a complete package that lets you create illustrations that are stunning in subtlety and detail while retaining the all important editability of vector drawing systems!
