For having access to this option you need to have two Mirone windows opened and the second must have been opened using the New empty window option. This is crucial for one need to know where to drape. Then, the image of the second opened window can be draped on the first one. If the fist image results from a grid you can still elaborate (complicate) more by applying an illumination. That illumination will change the Hue (from the HSV model) of the first image. Finally, this image can be saved with the Save As 3 GMT grids (R,G,B) option. Imagine that the first image was obtained from loading a GMT grid DTM model and the second represents a satellite image (or aerial photograph) of the same (not necessarily exactly equal) region. At the end you will have the GMT grid and the draping image split into three RGB grids. You can then use GMT to drape the three grids version of your photo onto the DTM. This option is also useful if you want to drape an image on a DTM before computing a Fledermaus object. A good example is to drape a backscatter image (preferable pos-processed with the ROI options) over a multi-beam bathymetry.
