# Exponential/logarithmic scaling in Illustrator?

Given a flat object in Illustrator, how can I scale it along the X or Y axis so that it stretches in an exponential fashion? That means that the center barely is stretched, but the outer extents stretch much more? I know there are some warp effects, but those seem to affect both axes.

• Interesting challenge! I got something that works using envelope distort with a mesh (a little bit like this, but ignore the stuff about blends, horizontal only e.g. a 1x6 grid, and scaling the grid lines outwards), and then scaling everything except the inner segment, then everything except the inner two, etc, so the grid lines are placed exponentially. But I can't get the maths quite right. How much wider should the final area be? E.g. if you start with a square, what would you want the final aspect ratio to be? – user56reinstatemonica8 Apr 20 '14 at 23:03
• Ideally you should be able to set the distance stretched and the degree of exponential stretching. – Keavon Apr 20 '14 at 23:07
• Did you look at scripting? How complex is the document? Can you share the document? – allcaps Apr 22 '14 at 14:21
• May be solution in that. See http://www.adobe.com/devnet/illustrator/scripting.html for docs. – user1844884 Jul 25 '14 at 10:14
• I know of no internal method which would work as you describe. Even 9-point slice scaling does the opposite of what you are seeking. – Scott Aug 18 '14 at 20:57

## Scaling the object using guides:

I made this template which contains the exponential/logarithmic lines.

Create a new letter size Document in Illustrator and Place the template.

Because in this case I'm going to use the exponential lines, we are going to lock it and hide the logarithmic lines.

Import your flat object into Illustrator.

Select your object and go to Object > Envelope Distort > Make with Mesh.

Depending on the orientation of the scaling, insert 13 and 1 respectively.

Now, that you applied the Envelope Distort to the object, Align each row/column of anchors with the template.

Result:

You may have some luck playing around with the transform effect tool inside the appearance panel.
