Recreating
Apple's Aqua Gel Effect with Xara X
Tools
and techniques for transparency with gradients
by Gary
Priester
Special
to Digital Media Designer
garypriester@earthlink.net
[Editor's
note: This is a Windows-only tutorial for Xara X, a vector illustration
application from Xara Ltd. (Those of you with Macs can easily
run Xara X via a Windows emulation program, such as Virtual PC
from Connectix.)
This tutorial focuses narrowly on one specific type of graphic,
but, in the process, you get to learn some of the workings of
the programquite a few, actually, since this mammoth effort
spans eight pages. If you're unfamiliar with Xara X or would simply
like to follow along, you can download a fully functional, 30-day
trial version of Xara X from http://www.xara.com/products/xarax.
D.N.]
Brendon
Carr is responsible for this month's tutorial that has touched
off a one-upspersonship contest in the
Xara X Conference, one of dozens of graphics-related forums
found at
TalkGraphics.com.
It all began
innocently enough when Brendon visited a tutorial posted on a
web site called Wardspring.com.
The tutorial (the result of which is the green button on the right)
attempted to recreate the secret process used
by the Apple design team to create the gel-like buttons featured
in the new Macintosh OS X Aqua interface. Brendon posed the question
how to replicate this effect in Xara X, not Photoshop, to the
visitors to the Xara X Conference.
I instantly
rose the the challenge and provided a simple six-step solution
in Xara X. Immediately other members of the conference submitted
their entries and enhancements and the race was on. In the end,
I think the Xara conference participants not only replicated the
aqua gel look, but surpassed it tenfold.
Xara's powerful
tool set including its unique gradient transparency and new feathering
tool (all this in a vector application), is what makes it so easy
to recreate this effect.
Without getting into
a long-winded discussion of Xara versus Illustrator or Photoshop,
it is worth pointing out how Xara handles transparency, especially
gradient transparency versus Adobe's method.
To apply gradient
transparency in Illustrator or Photoshop, first a black and white
gradient is created and then flat transparency applied as you
can see in the top example. A rather rigid method.
Xara can apply
gradient transparency directly to any bitmap, vector object, text
object, in grayscale or full color. The object is selected, Linear
(or other gradient transparency style chosen) and then the transparency
is applied interactively by dragging the transparency fill path
arrow on the selected object as you can see in the bottom illustration.
This provides Xara's unique ability to create incredibly smooth,
opaque to 100 percent transparency effects.
As I assume
most of the readers at this site have not yet heard of Xara X,
the killer vector application from England, I have tried to break
it into tiny steps so non-Xara users and Macintosh users can get
a good idea how it is done even without having Xara X installed.
If you don't
have Xara X, Click
Here to download a free, fully functional, 30-day trial copy.
Xara X is a Windows-only product but runs efficiently on a Macintosh
with a Windows emulator.
As always,
we will be working in Pixels. If you have forgotten how
to do this, open the Page Options dialog (right click on
an empty portion of the screen and select Page Options or
Utilities > Options). In the Units tabbed
section, select Pixels from the drop down list, and set
the Color Units: to 0-255.
In the Grid
and Ruler tabbed section set the Major Spacing: to
100pix (key it in exactly like this with no spaces) and
the Number of Subdivisions: to 10.
If you do
not see your screen rulers, go to the Window pull down
menu and select Bars > Rulers .
|
|
Enable Snap
to Grid. (found in the Window pull down menu).
Select the Rectangle
Tool on the main toolbar on the left of the screen.
Click and drag
a rectangle that is 250 pixels wide by 150 pixels tall. Refer to
the size on the context-sensitive Infobar at the top of the
screen and do not release the mouse button until the rectangle is
this exact size. The reason for this rigidity is we will be rounding
the corners of the rectangle and in order for the corners to be
perfectly round, the rectangle must be drawn to the exact size,
and not resized which will result in non-round corners.
|
|
With the rectangle
and the Rectangle Tool still selected, click the Curved
Corners icon on the Infobar at the top of the screen (it's the
inverted L- shaped button).
There are two
methods to round corners in Xara. The first is to drag the outside
control points on the corners with the Rectangle Tool cursor.
The second is to select Curvature from the drop down list
on the Infobar and click the right arrow button. In either case,
we want a curvature setting of 0.7.
|
|
Using
the Rectangle Tool, draw a second rectangle, 170 pixels wide
by 50 pixels tall. Again, draw the rectangle to the exact size before
releasing the mouse button.
Any questions?
|
With
the new rectangle and the Rectangle Tool still selected, adjust
the corner curvature to 0.5. |
|
Select the new
rectangle and then select Mould Tool. (Remember this is
a British product!) The Mould Tool is used to apply interactively
editable, enveloped shapes to objects, text objects, and groups
of objects.
On the Infobar,
select the Default Perspective envelope. (The second rectangle
button on the Infobar). Drag the bottom corner control handles outward
as shown. The modifications are applied in real time.
Disable Snap
To Grid ( Window pull down menu).
NOTE:
Xara has two kinds of interactive envelope shapes, straight sided
and curved sided. The curved sided envelope shapes use Bezier control
handles to modify the shape.
|
|
Select the larger
curved rectangle and apply a solid deep blue fill.
Select the Fill
Tool then from the drop down list of Fill Types on the
Infobar at the top of the screen, select Linear.
An arrow will
appear going from the center of the capsule shape to the right side.
Drag each end of the fill path arrow until it is going up and down
as shown.
I will explain
in a moment how to adjust the color using the Color Editor.
For the time being, just pick a deep blue. By default the second
color in a Linear Fill is white, which is what we want in
this case.
|
|
Creating multicolored
gradient fills in Xara X is intuitive and painfully simple.
With the Fill
Tool and the filled object selected, and the fill path arrow
showing, drag a color from the screen palette and drop it onto the
fill path arrow. The small icon to the right of the cursor changes
to either a thin line to indicate line color, or a square to indicate
fill. We want a medium blue fill.
NOTE:
Once
on the fill path, the color, or additional colors, can be dragged
to new positions if desired.
Additional
NOTE: Colors can be dragged and dropped onto non-selected objects
as well.
|
|
To access the
Color Editor (covered in the next paragraph) click the small
color wheel icon to the left of the screen palette. To add a fill
color to a selected object, click any color on the screen palette
with the left mouse button. To apply an outline color, click
with the right mouse button.
To set the fill
color to none, click the cross hatched square with the left
mouse button. To set the outline to none, right click the
cross hatched square or select None from the Line Width
drop down list on the Infobar.
|
|
To modify or
mix a color, use the Color Editor (click the color wheel
icon to the left of the screen palette).
If the Color
Editor only shows half what is shown here, click the icon directly
under the X button at the top of the menu to display the
Advanced Options.
In the Color
Editor, you can edit in RGB, CMYK, HSV, Grayscale and RGB Web/Hex
modes.
You can name
a color by clicking the yellow tag icon to the immediate right of
the color drop down list. Click the button to the right of this
to convert any mixed color to a web safe color.
Select the colors
on the Linear Fill and change their values as shown in the
illustrations.
NOTE:
If
you let the arrow cursor rest over any color on the screen palette,
a Tool Tip appears with the color properties.
NOTE
within a NOTE: If the colors shown in the Tool Tip are
in percentage and not 0-255, you need to change the Color Units
setting in the Page Options dialog. (See page 1). On the
other hand, if you are specifying color for CMYK printing, use Percentage
and not 0-255.
|
|
OK, back to the
tutorial.
As I mentioned
on the home page, Xara's Linear Transparency is unique. CorelDRAW
users should note that Corel's Linear Transparency was copied from
Xara's.
Select the white
highlight, then select the Transparency Tool from the main
tool bar. From the drop down list of Transparency Shapes
at the top left of the Infobar, select Linear.
As with the
Xara's Linear Fill (the two are quite similar) the fill arrow
appears in the center and extends to the right edge. Drag the control
handles on either end of the fill path until the top edge of the
highlight is almost opaque and bottom edge is almost transparent.
Extending the fill path arrow slightly above and below the shape
accomplishes this. If the transparency end of the arrow is inside
the highlight, the edge cleanly disappears.
At this stage,
except for the type and the drop shadow, we have replicated Apple's
gel effect, without ever creating or editing a bitmap!
|
|
Now it's time
to take the Apple effect to the next level.
Select the
blue capsule shape, then select the Transparency Tool. From
the drop down list of Transparency Shapes found top left
of the Infobar, select Elliptical.
By default,
Elliptical (and Circular) creates a transparency
that is transparent on the outside and opaque in the center. We
need this to be the other way around. With the Transparency Tool
selected, click on either of the outside squares at the ends of
the fill path arrows. Change the setting by dragging the Transparency
slider on the Infobar to 20%. Click in the center square
and change the Transparency slider to 100% .
Click again
on the center square and press the arrow keys on your keyboard to
move the transparency center down as shown. Cool?
NOTE
of PRIDE: All the screen images
for this tutorial were created in Xara X.
|
|
What's missing
from our gel capsule is a shadow. We can add a soft diffused shadow
with Xara X's new Shadow Tool.
Select the blue
capsule shape, then select the Shadow Tool. Click the second
effect from the left, Wall Shadow (the far left box removes
the shadow).
Reposition the
shadow so it is directly beneath the capsule by dragging the shadow
with the Shadow Tool.
NOTE:
You can also intuitively add a drop shadow to any object, or text
object, by selecting the Shadow Tool, then dragging on an
object in the direction you want the shadow to fall. It's kind of
like magic!
|
|
It's not that
I don't have the greatest respect for Apple's design team, but a
gel-filled capsule does not cast a gray shadow. It casts a shadow
the color of the gel.
To achieve this
effect, select a solid blue color on the screen palette and drag
and drop it onto the shadow. Compare this to the example in the
previous paragraph. Which do you think looks more realistic?
|
We
are going to add a light gray background behind our capsule. It doesn't
need to be exact, but draw it more or less to the size shown using
the Rectangle Tool. Apply a 10% black fill. |
|
Draw another
rectangle, this time exactly the width of your rectangle and 2 pixels
in height. The easiest way to specify this is in the W and
H (Width and Height) text entry boxes on the
Infobar. To apply changes that are not linked to one another, press
the tiny lock icon button on the Infobar so it is in the raised
(non-proportional scaling) position.
Make a duplicate
(Ctrl K or Edit > Duplicate) and position
it at the very bottom of the page. Position the first rectangle
at the exact top of the page.
Apply a 20%
black fill to both rectangles and set the line width to none by
right clicking on the cross hatched square to the left of the screen
palette.
|
|
In this step
we will create a blend between the top and bottom rectangles.
Select the Blend
Tool. Click on the top rectangle and drag down to the bottom
rectangle. Release the mouse button.
You should have
a 5-step blend. Change the number of Blend Steps on the Infobar
to 18 and press Enter on your keyboard to apply the
changes.
|
|
Select
the blended rectangles and the background and press Ctrl B
(as in Back) to send them to the back, or select Send to Back
from the Edit menu.
NOTE:
To multiple select objects, hold
down the Shift key on your keyboard while you click on multiple
objects.
|
|
Select the blended
rectangles and the background and group them (Ctrl G or Arrange
> Group).
Select the capsule,
and the background and line group, and make a duplicate. Edit
> Clone or Ctrl K.
Select the capsule,
then the Shadow Tool , and click the left square shadow icon
on the Infobar to turn the shadow off.
|
|
The lines behind
the blue capsule would be distorted due to the roundness of the
capsule.
Center the duplicate
capsule over the duplicate lines and background. Select the lines
and background, select the Mould Tool, then click the Elliptical
Envelope button on the Infobar. The enveloped shape can be seen
over the original background.
|
|
The enveloped
background and lines are wider and taller than the duplicate capsule
shape.
Select the enveloped
lines with the Selector Tool. Click the top center control
handle and while holding down the Shift key, drag towards
the center. The Shift key constrains resizing so the sides move
either together or apart the same distance.
Repeat this
to make the width narrower. The enveloped shape should extend slightly
beyond the capsule shape.
|
|
Place the capsule
shape on top of the enveloped lines and background. Select the capsule
and the lines and from the Arrange pull down menu, select
Combine Shapes > Intersect Shapes. This crops the
lines to the shape of the capsule.
Hold down the
Ctrl key and click on the black outline around the capsule
to select just it and not the entire contents, and set the outline
to none.
|
|
Select
the intersected lines and the background group, and send both to
the back (Ctrl B or Arrange > Send to Back).
NOTE:
Another
way to do this is to select the intersected lines and press Shift
Ctrl B to send the lines Backwards. This sends the selected
object(s) back one layer at a time.
|
|
Select
the Text Tool, click on the page to place the insertion cursor,
and key in XARA ROCKS (it really does, don't you think?).
Highlight the text by dragging the text cursor over it and click
the Center Justify icon on the Infobar.
The font I
have used is called Valken, and is available from Xara's
BuyFonts.com
or in the Fonts
folder on the Xara CD.
With the text
still highlighted, click the down arrow next to the Line Spacing
text entry box until it reaches 70%. Click the right arrow
next to the Tracking text entry box until it reaches 100%.
Visually center the text over the capsule.
|
|
This next step
is a bit convoluted and for it I apologize.
Make a duplicate
of the capsule. With the duplicate selected, click the Shadow
Tool and click the No Shadow icon (far left). Next select
the Transparency Tool and select None from the drop
down list on the Inforbar.
Now, copy the
capsule (Ctrl C or Edit > Copy). Select
the text and press Shift Ctrl A or Edit > Paste
Attributes . This is Xara's equivalent to Adobe's eyedropper
tool and is used to copy all attributes from one object to another.
Including transparency. Your text should now look like the text
shown here. Delete the duplicate capsule. Because the capsule had
multiple special effects, copying and pasting attributes did not
have the desired effect.
|
|
Xara's new Bevel
Tool is hot with a capital H . Select the text then select
the Bevel Tool. From the drop down list of Bevel Types,
select Flat. On the Infobar press the Inner Bevel
button (the in-facing arrows) to apply the bevel to the inside of
the text. Amazingly enough, the text is still editable!
Set the Contrast
slider on the Infobar to 80%. From the Slider Type
drop down list, select Size and change the setting to 2.
|
|
The embossed
text looks nifty except the text wants to look recessed.
Piece of cake!
Just grab the light source arrow in the center of the text and drag
it 180 degrees to the bottom as shown. Now the text looks as if
it's recessed.
We could leave
it here. But we won't. You should be naming and saving your image
as you go along. But in case you're like me, and have completely
forgotten to do so, name and save your file now and take a break
to rest your eyeballs.
|
|
OK Is everybody
back from your break?
Not only can
Xara apply some awesome bevel effects, but the bevel can be a separate
color, same as with the Shadow Tool.
Find RGB 102,
153, 255 medium blue on the screen palette. Drag and drop the color
onto the bevel.
|
|
We're going to
apply transparency to the beveled text so we can see through it.
It will be easier if the portion of the blue capsule shape is removed
first.
Copy the beveled
text to the clipboard (Ctrl C or Edit > Copy
).
Select the beveled
text and the blue capsule and from the Arrange menu, select
Combine Shapes > Subtract Shapes.
|
|
To paste the
beveled text in exactly the same position from which it was copied,
hold down the Shift and Ctrl keys and press V.
Select the beveled
text, select the Transparency Tool and apply a Flat,
Stained Glass transparency.
NOTE:
Xara's Stained Glass operation is the same as Adobe's Subtract.
|
|
Make a duplicate
of the beveled text. Convert it to editable shapes (Arrange
> Convert to Editable Shapes).
Ungroup twice
(Arrange > Ungroup). Delete the solid portion of
the text leaving just the beveled portion.
To delete in
Xara just press the Delete key on your keyboard or right
click and select Delete from the pop up menu.
|
|
Position the
empty bevel over the beveled text.
This last step
was not really necessary but enhances the light and dark of the
beveled edges.
|
|
The problem with
most vector applications is vector objects are too hard edged producing
an unrealistic effect. If we were in Photoshop, we could apply a
tiny amount of Gaussian blur to soften the white highlight and make
it softer.
But who needs
Photoshop when we can add a small amount of feathering right in
Xara X! Select the white highlight. In the upper right corner of
the Infobar, move the Feathering slider to about 2 to 2.5pix.
Doesn't that look more realistic?
|
|
Since we went
to all the trouble to lighten the bottom of the blue capsule using
Xara's Elliptical transparency, we should go the extra 9
yards and add a soft shadow beneath the text.
Duplicate the
beveled text. (Ctrl D) and convert the duplicated text to
editable shapes (Shift Ctrl S)
Select the Mould
Tool and apply a Default Envelope. (The first rectangle
button on the Infobar). Click in each corner and drag the Bezier
control handles downwards as shown. Drag the bottom handles a little
more than the top ones.
|
|
One
of the few features missing from Xara is a Gaussian Blur filter.
But lucky for us, Ladislav Seridi has created a cute little utility
called SL Blur which can be downloaded for free from the XaraXone
Shareware
Page along
with a ton of other cool shareware and freeware stuff.
Select the text
and from the Arrange menu, select Create Bitmap Copy.
From the Color Depth drop down list, select True Color
(24-bit). And press Create.
Copy the bitmap
to the clipboard.
Open SL Blur
and press the Clipboard icon on the far left to paste the bitmap.
Move the slider
to 10 and check the Add Border check box. Press the water
drop button to apply the blur. Press the Copy button (to the left
of the hand button), to place a copy of the blurred bitmap in the
clipboard. Close SL Blur and say thank you, Ladislav.
BY THE WAY:
Add Border automatically expands the width of the bitmap to accommodate
the blurring. If not checked, the blurring is truncated.
|
|
We're almost
finished.
Paste the bitmap
( Edit > Paste). A dialog box will appear with
two choices: Bitmap and Device Independent Bitmap.
Select Bitmap and press Paste.
Position the
blurred bitmap text below the beveled text. With the bitmap selected,
select the Transparency Tool and apply a Flat, Stained
Glass transparency. Stained Glass treats white as transparent.
|
|
Marquee
select the beveled text and the white highlight (drag a rectangle
around it with the Selector Tool) and bring the beveled text
and white highlight to the front (Ctrl F).
NOTE:
Unlike Illustrator, you have to marquee select the entire objects
not just a portion.
To increase
the intensity of the white highlight, you can make a duplicate (Ctrl
K).
|
|
And here's the
final image.
So what do you
think?
Any of you
Mac users impressed or do you think you can do the same thing in
Illustrator, FreeHand or Photoshop?
Let me know.
By all means, please e-mail
me your comments.

I want to thank
Ross Macintosh, Big Frank, and all the contributors to the Xara
Conference for suggesting many of the techniques used in this tutorial.
The final effect was a genuine collaboration.
