My stakeholders now want an HTML-style image map -- a map of counties divided into regions, where tapping on a region brings up a list of counties in that region (I already have all that functionality working as a table view. The image map idea is pretty good, though.) The regions, each one a collection of counties, is like a jigsaw puzzle piece in outline.
I have a public domain map of all the counties in question. What I'd like to do is use the map image (with each region having a different fill color for all the counties in that region) and then draw the region outline using Core Graphics custom drawn shapes with a transparent stroke and fill, and then use an appropriate event handler when a shape is tapped. I have a couple concerns about this approach. First, I've only used images in images views and custom buttons so far, and I've drawn shapes with simple CG techniques. But I don't know how to combine a UIImageView with a CG drawing context. Is there a way to do that and then draw the shapes over the image view? Or do I need to place the image in the CG drawing and then draw the shapes over that image? How is that done? My second concern is drawing the region shapes themselves. I'm envisioning a lot of painstaking point-by-point trial and error between the code and the simulator for review. (I'm doing everything programmatically and not using IB at all in this project.) Is there an easier way to go about this? --Chris -- View this message in context: http://monotouch.2284126.n4.nabble.com/Trying-to-Create-HTML-Style-Image-Map-tp4656120.html Sent from the MonoTouch mailing list archive at Nabble.com. _______________________________________________ MonoTouch mailing list [email protected] http://lists.ximian.com/mailman/listinfo/monotouch
