Using Captivate 5.5
There is no alpha setting for strokes, so when I want to have no stroke for an object, I set the stroke to zero. But even at zero, Captivate shows a thin stroke. Is there any way to completely remove the stroke?
For example, if you draw a rectangle, set the fill to zero alpha and the stroke to zero thickness, the result will be obvious.
Are you absolutely sure that the stroke set to 0 is visible at runtime? Are you referring to the stroke that remains visible in Edit mode as a guide only?
When I set my stroke to 0, I can still see a fine line in Edit mode to tell me where the boundary of the rectangle is. But when I publish or preview that file, I see nothing.
As Rod points out, you are probably only seeing the 'path' indication in editing mode. What is confusing to me, because I have been asking the same question (yes, I sometimes ask questions) is that this 'path' indicator seems to have a width of 1px and has the same color as the Stroke color. In other applications (like Photoshop) this path line is a hairline and always black, moreover you can turn it off in editing mode as well. I have been asking by feature request to have this also in Captivate: a black path line, finer (or eventually dotted...) than the 1px line and ability to turn it off to have a more WYSIWYG view in editing mode. But no luck so far...
