I thought I was going to be able to revise an old time animation to use a trick I just learned with representations to get the marker ( a little fish) to lie parallel to a line feature class (the river). All I would need to do would be convert linear events to a geodatabase feature class, then convert the symbology to a representation. But before that, I thought I'd better take the time to flip the marker over so the little fish swim the right direction. Looking for a mirror image flip. A 180 degree rotation will point the fish in the right direction but he'll be upside down. I was looking at the 10.2.2 Symbol Property Editor but didn't see a mirror image flip option, just a rotate. I can see that the Type is a Picture Marker Symbol but it isn't linked to an external file name. Must be stored in Arc somewhere. I had hoped I could find a reference to a file location so I could edit the graphics file externally, because I haven't been able to find it with Windows Explorer. Knowing the file name would help.
Looking at Style References, I see a style that I created, Paul. it's checked but grayed out. I wonder if that means I left the style file behind on a old PC in Users\...\Appdata. In this computer's AppData\Roaming\ESRI\Desktop10.2\ArcMap and in Desktop\10.1\ArcMap I found a couple Paul.style files, but adding the style files didn't correct the style file from being grayed out. Besides, that won't help me flip the graphic.
I couldn't find a way to export the marker from Symbol Selector to a graphics file that I could edit with another editor. I might be able a snip the symbol off the screen but then I would have to trim off all the background.
I went ahead and Converted Symbols to Representation so I could see what I could do in Marker Editor, but this step stripped off the marker outline that I had as well as made the marker much smaller. How did that happen? And I didn't see anything in Marker Editor that would do a mirror image flip.
Stuck every way I go. What do you suggest?
