Raised baseline for type on path after rotation

[sPretzel]

Hello,

Something weird is happening to type on path after I rotate the object it's on. When first creating the type on path, the baseline sits flush with the path it's on. After rotating it, at some point, the baseline is slightly raised (a fraction of a point) with respect to the path. It's a fraction of a point but the baseline line and the path are shown to be clearly separate from one another, so it's noticeable. If I drag the centre bracket to the other side of the path (flip), the type is flipped and the baseline is restored to being flush with the path again.

1- Is this a bug? It looks as though it doesn't happen consistently.

2- If I manually flip the centre bracket twice consecutively (flip and back), I restore the baseline to where it should be. But flipping type manually is not accurate and can slightly move the text to the left or the right. Can I accomplish this flipping without affecting the position of the centre bracket with respect to the path?

Note that Type>Type on a Path>Type on a Path Options>Flip does just that but it also preserves the slightly raised baseline unfortunately. So it doesn't solve the problem.

3- Is there another workaround or solution?

This is for CS4. Thanks.

There is one more issue that occurs here and I will outline both here, so you can try to reproduce them. Again, this is in CS4.

Draw a circle, say of width=4in. Type a character on the path. Centre it at the top of the circle (90 degrees). Look at the line that outlines the baseline and how it sits flush with the circle. Then Transform>Rotate (copy) every 15 degrees. You might observe the following.

1- In some rotated copies, the baseline is no longer flush with the circle. It may be very slightly above or below the circle. You must zoom in a lot to see that. It doesn't happen for every copy. This is the issue I described in the original post.

2- For each copy, read the w and h. You will see that some are no longer w=4in but slightly off, say 4.0011in.

Both of these issues look like an Illustrator bug to me.

I think they are rather a circle bug. Circles can't be draw exactly using Bezier curves (and there are some threads on it). Especially when you rotate in 15° steps you will notice that.

You do know that there aren't a lot of folks whose operating system allows them to still run CS4?

Hi Monika,

I think your answer refers to issue #1. That being said, in the original post, I do mention that if I manually flip the type and then flip it back to its original position with respect to the path, that baseline shift goes away. So I still think it's a bug. Can you reproduce that in CC?

Can you reproduce issue #2 in CC? I don't think that simply rotating a circle with type on it, despite Bezier curves, should affect the dimensions of the circle.

I didn't understand too many of the steps you mentioned in your first post unfortunately.

Please show images.

You can do the most simple part. Draw a circle of width=4in, rotate it by 15 degrees (rotate+copy multiple times - select copy in rotate tool). Then inspect each copied circle. I see that not all circles have width=4in, some are 4.001in, 4.0007in, etc. This is issue #2. There is not even type on path here!

As I said that is an issue with circles and Bézier paths and there are a couple of threads on it.

Is that one such thread?

I had searched the forum here prior to posting but had not found anything that I thought was related.

I find these issues with Illustrator unnerving. So much time is lost trying to understand if it is a user mistake, a bug, and if there is a workaround. It would be great for the user that Adobe releases an official list (periodically updated) of such known issues. This isn't a bug then, as it is "intentional", but a limitation of Illustrator. And by the sounds of what you are saying, it is still a limitation in the latest version of Adobe Illustrator.

The point you make probably explains issue #2 and might also explain issue #1 but it doesn't explain why I can manually correct for issue #1 after the flip/flop operation!
