How to enlarge image without distorting it?

Question

I would like to double the size of this image without causing any pixelization.

Can you please let me know how can it be done?

Thanks!

Answer 1

It's going to largely depend on the original size. Photoshop is many things, but it's not magic. It can do some fairly impressive things with pixel interpolation but there's a limit.

I would suggest using "Image" -> "Image Size..." and scaling it that way - at least it will scale consistently. I am not quite sure how exact you need to be when you say "any" pixelation; this method may allow you to scale this with a minimum (i.e., not noticeable by anyone who's not looking for it) amount.

If you're really worried about this I'd create it in a vector-based program like Illustrator (it looks like it'd be a fairly simple job) so you can scale it to any size your heart desires.

Answer 2

With this particular image, I'd scale it up with Image Size at 200%, using bicubic interpolation, and then correct the issues.

The only areas where pixelation will be noticeable will be:

• the arrow symbol. Was that based on a dingbat font symbol? If so, should be easy to recreate.

• the right hand angled outline. Copy a rectangular area from just left of the arrow symbol over the scaled-up right hand end, then use the polygon select tool to delete from this leaving a crisp edge. Angles look to be 45deg which will male it easier.

• possibly the dividing line between the two types of fill. Copying and pasting will fix this.
