Hi Ugo, These problems are both now fixed. > The new thing is the alpha value, which make missing values invisible > (or, better, transparent). The problem is, when I click Point Mode on > the GraphicsModeWidget I get a black display. I haven't changed anything > regarding other stuff, just added a Display.Alpha Map. Where's the > catch? PointMode now works with Alpha, although the points are not transparent - transparency only applies to surfaces. The points are now visible, however. > Another question, when I switch the colour tables on the fly (with > ColorControl.setTable()), I get an ArrayIndexOutofBounds Exception. Is > it possible to resize the colour table, without having to reconstruct > the display? Or should I stick to a standard colour table size? The Exception came from the widgets attached to the ColorControl, and they have now been fixed. You could always change the size of a color table on the fly, but attached widgets couldn't handle it correctly. Now they can.
