Zoom Picture causing image to get fuzzier

Hi Diane,

1.Okay, let me see if I understand. The image when zoomed in is clear but fuzzy on the slide when zoomed back out. Right?

2.Your examples show the picture to be clear although small when not zoomed in, while your zoomed in picture is fuzzy.

If it's the first one, I wasn't able to replicate that myself. Would you mind sharing the file here so that I can take a look and see if I can get it to do what you are having trouble with on my computer.

If it's the second one, it will be that way because the quality of the image doesn't appear to be that great. The higher the resolution, the clearer a picture will be when zoomed in.

Always Happy to Help,

Adrian

Thanks for taking a look at it!

You are correct: it looks fine when magnified, but the regular image is blurry.  Both images shown above are the exact same image.  The only difference is that one has the zoom effect applied.  If I take off the zoom effect, it goes back to being clear.

I cannot share that exact file for client confidentiality reasons, so I made a new one-slide story. (attached)  In the new file, the zoom is working just fine.  So I imported one of the many troublesome slides from my client file into this new story, and it has the same problem.  Just for kicks, I added a new image to the same slide, and there is no issue with the zoom.  

Very strange!

Hi Diane,

I downloaded your file and got the same thing you did. I even took the picture and created a new project with just the one picture that's giving us trouble. It looked fine on the slide, but when I previewed it, the picture was fuzzy until I clicked the zoom picture. I'll continue to play with it and maybe someone else will have an idea in the meantime.

Thanks for looking into it.  At least I know it isn't me!!  I'll see if I can put the image on a slide in a new story that isn't causing problems, and then import it into the troublesome course.

Hi Diane,

It was no problem. A part of me thinks that it's the picture itself. I just now thought about that angle. I'll look at it here in a little while and see if messing with the properties of the picture, maybe changing how it looks, and see if I still get the fuzziness or not.

I thought of that, too.  I tried removing the animations and the rotation, but that didn't work.  Maybe you'll try something I didn't think of.  It is also happening to other (but not all) images in that course.  I don't think its the file type either: some of the problems are with gif and some with png, while other pngs are find.

Hi

How did you solve that problem? I've got the exact same issue.

Hi there Helene,

Looks like this was happening quite some time ago for Diane. I'm not sure how she resolved the issue.

Are you able to share an image or .STORY file? I'd be happy to take a look, if you'd like. 

One thought did come to mind for a workaround, until we're able to fix this for you. You could mimic the "Zoom" effect by creating a copy of the image and scaling it to how you'd like it to appear. Place that additional image on another layer and have it show when the user clicks on the original image.

Thanks!

It's the image resolution! At least that's what I found when I ran into this same problem. I used photoshop to increase the resolution from 72 px/inch to 300 px/inch. Of course this creates a much larger (and grainier) image than I wanted, so I sized the image back down to its original dimensions where it appeared crystal clear again. When I inserted the "new" image and applied the zoom feature, voila, the image was not fuzzy any more when using the zoom effect.  Hope this works for you! If you don't have Photoshop you should be able to use another photo editor to increase the resolution.

Thanks very much for the information, Lesley!
