Try OMSCalingRaster. It will allow you to load an image from a file and to project it to the map with an upper left/lower right coordinate pair and a width/height. You can add it to your OMGraphicsList with vector graphics like a flood boundary or roads. By placing your flood boundary vector graphic above your image in your list the vector graphics will print out ontop of the image. Then you can write it out to a jpg file.

Subject: [OpenMap Users] outlining an image, reprojecting onto map
We had major flooding in PA yesterday, as has much of the East Coast.
In this picture:
http://knauth.org/gsk/flood-040918/images/14.html
I want to mark some points on photos like the one above, draw some
outlines of flood limits, and then reproject the graphics onto maps. I
know the math exists, I just don't know how hard it is.
County officials are trying hard to understand the limits of
yesterday's event, to improve flood mitigation plans. I'm just looking
for ideas.
Geoffrey
