<div>Ran into an issue today that probably requires some developer input. </div>
<div><br>
</div>
<div>Objective 2 shaded contour plots, with variable transparencies to view 2 variables on top of each other. </div>
<div><br>
</div>
<div>This works as desired in CellFill but is not aesthetically pleasing due to the blockiness. </div>
<div>AreaFill also works but has some weird vertical lines that pop up in random places (and takes an age to plot).</div>
<div>RasterFill does not seem to support RGBA with cnFillPalette or cnFillColors a halfway workaround works with cnFillOpacityF but following on from the thread the other day this only works with all or none of the colors. </div>
<div><br>
</div>
<div>So main question should/can RasterFill support the A in RGBA colortables. It seems the functionality is there just maybe a break in the chain somewhere. </div>
<div><br>
</div>
<div>plots: </div>
<div>
<div><br>
RasterFill w/ cnFillOpacityF semi transparent everywhere --></div>

<div>Cell-fill What I want but without the blockiness --> <a href="http://www.atmos.albany.edu/student/abrammer/transtest/transtest_CellFill.png" target="_blank">http://www.atmos.albany.edu/student/abrammer/transtest/transtest_CellFill.png</a><br>

<div>RasterFill w/ RGBA same resources as cell-fill but fails completely. --> </div>
