Hello,  
I have a DEM with TIFF format and a color scheme. I’m trying to change the color scheme to other color scheme but after it`s not work. I note that property ImageColorScheme of Image is not changed after I set the new value.  
Here is my code in pascal, where IMG is created from a DEM file:  
…

```
  img.TransparencyColor := 0;
  IMG.ImageColorScheme := FallLeaves; <--- this line not work is read only?
  img.UseTransparencyColor := true;
  Map.Redraw;

```

…

I observed the IMG.ImageColorScheme := FallLeaves not change. Does someone could help me please or give a idea how do it in C?

Thanks

Hi,

I still have this problem. Please, I need to solve this.  
There’s a way to change the colorscheme and update the map without have to remove the layer?  
Regards,
