- It seems to me that these .cpt files already define the number of steps and<br>the class boundaries. Maybe it would be an option to have a button 'from<br>color ramp...' in the graduated symbol dialog that opens a dialog where the
<br>available ranges are visualised. Then, after selecting and clicking ok, the<br>classes, number of classes and their boundaries are directly inserted into<br>the list. The same dialog could also be used for the continuous renderer
<br>(where the interpretation of the ramps would be continuous) so the ramps<br>could be stored in one directore. What do you think?</blockquote></div><br>I like having the color ramp as another standard option in the main dialog window. I'm not sure if Qt can do this but it would be nice to see a dropdown of visual representations of the ramps (a bunch of 100x20 jpgs) to select from. But in terms of a dialog box that could be used in other contexts, your idea of having a "From Color Ramp" button might be better.
<br><br>In terms of getting this implemented, I just hacked this patch together for graduated symbols but it would be worthwhile to abstract the color ramp handling into a separate class so that all the various renderers can it.
