Art boards extra pixel issue

I'm not sure if I understand your question correctly but I'll give it a try.
Illustrator doesn't have "pixels" so do you mean stray "points"?
If I delete a path and the end points are not also selected, they remain and I usually can't see them. When you finish working with your image, choose "Select > Object > Stray Points" to select the points, then you can delete them.
Hi Steve, sorry didn't explain myself to clearly.
When exporting bitmap based files (PNG's, JPG's ...) out of Illustrator using the art board as a bounding box for the file, it will almost always off-set the artwork and included a white pixel border where it used to be (even if transparent background is selected) .
If I don't use art board setting it works fine, this only becomes a problem when I have multiple art boards in the single file or have elements leading off the edge.
Makes for a tedios clean up job in photoshop as it will effect some art boards and not others.
Thanks for the tip on Stray Points, will be using that for other clean up.

JPStallard,
The boundaries of your artboards should have integer values as measured in points/pixels (start at integer values and have integer value(s) size), with another term: the artboards/resulting artwork should be aligned to the pixel grid (CS5 speak).
I have the same issue and everything is aligned to the pixel grid, the units are set to pixels. But it always adds 1 extra pixel to the artwork. Has anyone found the fix to this?
Hi TB
I found my issue was the artboard was not properly aligned to the pixel grid. It was a sub-pixel off (0.2345, not 0) which then added pixels around the artboard when exported.
Thanks, I have perfectly aligned the art to the grid and the artboard is as well, but still getting one extra pixel in height. This is in CS5.5, seems like something they should fix, when you define a precise artboard that the artwork crop exactly to it.
TrajanB,
Are you sure there is nothing beyond the top of the topmost object (spine of path), such as half a stroke or an effect?
It is a very simple drawing, no effects, no clipping paths, the art and the board is exactly 512 x 512 and aligned but the export always becomes 512 x 513.
Trajan,
And the artwork is still 512 x 512 when you Edit>Preferences>General>Use Preview Bounds?
Yes, and when I "Save for web and device" it is exactly 512x512, but export png from selected artboard it adds the extra pixel. Seems like a bug.
Seems like a bug.
Indeed, Trajan. And apparently a new one in CS5, since JP got it to work in CS4.
