Question

PLEASE HELP! How do I stop pixelated edges when I rotate images?

I am designing for the web in CS5 - and everytime I rotate the product images on an angle the edges go all jittery when doc is at 100% (Both when it is exported and in InDesign).

Yes InDesign is set to Highest image quality, and the images themselves are set to Highest display quality.

Yes I've used the right export options - I export at highest qualtiy - but the images are (and have to be) 72DPI because they are for web.

Yes I have the actual PPI and Effective PPI both at 72.

Images are PNG files to preserve transperancy and to be web friendly.

You can see in this shot below that the non-rotated image (Dinner Quiz) looks great, but the other angled images look awful.

Please help! I've been using InDesign for years but never had this trouble until I used CS5 I don't think.

    try to right click the image on your library and turn the smooth property to "on".

    This is a fact of life with low resolution imagery or on-screen display of any edge which is not truly horiozontal or vertical.

    Your screen uses rectangualr pixels for dispalying the image, and pixels are either lit or not lit, you can't have a pixel that is half black and half white, for example. Diagonal and curved lines must be represented by a series of short horizontal and vertical segments (these sements can be as short as one pixel in each direction) that look like stair steps. Imagine drawing the outline of your image on graph paper and being forced to follow the grid lines to get from Point A to Point B -- that's what you are seeing on your screen.

    Yeah, thanks! I understand that, but what would be a way to get around it so my boss is happy with what the photos look like?

    The thing about facts of life is you don't get around them.

    Take a look at similar images elsewhere on the web. Do they look better?

    Resolution on the web doesn't exist, by the way, only pixel dimensions, so it's the number of pixels you use to make the image that counts, not a physical size at which those pixels will be represented in print (that's what resolution means).
