Hi, the question about the combination of a bitmap image with an ordinary graph was posted recently, here is my answer again -------------------------------------------------------------------- Hi, If you import an image, it had the xy-box of the pixel dimensions but you need the plane area of your contour plot. The simplest way to do it is yourBitmap = Import["/export/home/kuska/mathpng2/Pictures/tigerg.png"]; ContourPlot[Sin[x*y], {x, 0, Pi}, {y, 0, Pi}, ContourShading -> False, Prolog -> {yourBitmap[[1]] /. Raster[bm_, rr_, more___] :> Raster[bm, {{0, 0}, {Pi, Pi}}, (* Place here the new bound used in the contour plot *) more]}] be sure to set the shading to false (otherwise the polygons overlay the bitmap). Set the bounds of the Raster[] object to your area in the xy-plane used in the contour plot. ------------------------------------------------------------------- You can use any 2d grpahics but you must ensure the correct xy-Range. For 3d objects the prior conversion to a 2d graphics may usefull.
