Snapping gone wrong

[Mads_Kl...@adobeforums.com]

Hi guys.

I really need some help here.

I have a canvas which is 1680x1200 and i'm designing a website. I've added some guides around the canvas but here comes my problem. Everything i create which i want to snap to those guides - snaps ½-1px outside og inside the guide. I have nothing else on the canvas that they can snap too.

I've looked around for ages for a solution without any luck so i hope someone in here can guide me through this problem as it has had me gone through changes on the webdesign for a month now.

Why don't you use Snap to > Document Bounds instead of Snap to Guides?

What does that do?

Mads: Have you looked at the snap really close up? I am sure that you will find that it 'looks' like that until you get really close up.

[Mads_Kl...@adobeforums.com]

Yes i have tried to zoom in at 1600 and 3200, and it does go outside.

But it seems its only a "fragment". Its like a bit of it but only at a low opacity.

I've never experienced this with CS3. I have never worked on a 1680 canvas before either though so i don't know if that can have anything to do with it?

Are the created items anti-aliased at all?

I've been looking for the anti-aliased settings, but cannot find them so i am not sure. Should they be or?

Do you have 'Snap to pixel' selected?

[Mads_Kl...@adobeforums.com]

I don't see the Snap to pixel option in the Snap To menu?

You have to make sure that the guidelines are actually positioned precisely on the line that separates one row or column of pixels from the row or column adjacent to it.

Also, understand that when creating anything that is vector-based (custom shapes, paths) that the edges of those objects aren't constrained to necessarily snap to pixel edges, unless you set them to behave that way in the Options Bar. With raster-based objects (marquees, masks, any sort of painting, blurring, erasing, etc) they—by definition—will either fill an entire pixel, or they will not. Never forget that anything displayed as pixels can't fill only a portion of a pixel. The pixel is either fully "engaged" or it's not. There is not half-a-pixel with raster-based display of an image.

The following thread may be related to the problem you're having, or it may not. Either way, the original question—and my long-winded explanation—might help increase your understanding. Hey...it's worth a shot! :)
