"find edges of image" plugin?
-
G'day everyone,
Just wondering if there was a plugin for "finding" the edges of an imported png file with transparent areas. I draw my own trees and import them as png, but in order for tem to cast a shadow I have to trace them which takes forever, even if I do it first in autocad. just wondering if there was a plugin that located the non-tranparent areas and created an edge.
-any help would be great, cheers

I don't know of such a plugin. However, if you haven't already checked it out, the Ruby Library Depot, maintained by Didier Bur, may have something. Or Smustard, or look in the Plugins and Extensions Index in this forum.
Then again, someone else may reply soon with either the methodology or a plugin.
Good luck -
There is a freeware application called WinTopo that will find edges in a raster image and create vector lines from them. You can save the vector lines as a DXF file which you could then import into SketchUp.

Rick Wilson wrote a SketchUp plugin for finding the edges of images. The plugin is free, but the application is a service where images are sent to a server. You need to purchase image processing credits, but the cost is reasonable. But since it is a SketchUp plugin, you get a Component sent right to your model from the image you upload.

There's also RasterVect Free Edition which can vectorize .bmp's and export to .dxf.
