Hi, I am building a GUI for image display with the following specifications. 1) Choice of colormap 2) Colorbar 3) Window/level setting by mouse drag 4) Scalable display 5) Print function 6) ROI functionality (segmeneted polygon only, multiple ROIs) I had the first 5 done using direct graphics. (2) and (4) using David Fannings colorbar and print routines. I figured that the ROI function was best implemented using Object graphics (OG) as i saw XROI and figured that i then didn't have to worry about a lot of the drawing myself. I was happy with the OG approach until implementing the colorbar using OG. It seems the documentaton is erroneus, or at least i cannot seem to control the colorbar layout. 1) The questions in now - should i stick to OG and is there some way to get Davids colorbar into an OG window. I would like to keep things simple and have all graphics in one window - it makes printing easier. 2) Am i right that multiple ROIs are best managed using OG? Best regards Soren
