I am using Illustrator CS5 and am having trouble exporting a .ai file to a .png with a transparent background. I am making images for a graphical display and wish for it to be transparent beyond the graphical image itself. Please help.
Is there a white rectangle shape behind the 6 dots that defines the boundary of the image in the Ai file?
If not, then only the grey dots would be exported with a transparent background.
Below is a screenshot of a AI file exported as PNG and viewed in Photoshop.
The boundary of the exported image is defined by the outermost elements. So I suspect in your case, there is a white opaque rectangle which is the reason why you didn't get a transparent backgound.
I don't have Illustrator CS5 so I used CS3. Hope this helps.
The rectangle shape is the same scale as the image that it will overlay.
This puts the needle rotational axis (dots), for each gauge in the proper
place. It is intended to simply be a layer on top of the gauge needles and
dials. I'll try to export using the boundary of the image itself. Thanks!
