Grads users,<br>I hadn't heard a response on this issue and it's been awhile. I was wondering if anyone else has noticed this or knows why it's happening and/or how to stop it. Thank you.<br><br>Jeff Duda<br>

Hello,<br>I keep seeing strange things when I try to plot a colored filled polygon and then save the image, in particular within a colorbar. I'm using the color bar script provided in the scripting library page, <a href="http://cbar.gs" target="_blank">cbar.gs</a>. The retangles always seem to "bleed" over the top line of the colorbar (seen only in horizontal color bars). The original script doesn't have a black outline drawn on the top of a horizontal color bar (well it does, but it is covered up by the filled colored polygons). I thought that made the color bar look tacky, which is why I modified the script ever so slightly to get that top line to appear. As an example, I've attached 3 images all of the same data, but presented in different ways to show how the color bar acts.<br clear="all">
<br>grads.png is a screenshot of my grads window (using the print screen key) showing the color bar appearing correctly as I want it to.<br><br>2.gif was obtained by issuing the command "printim 2.gif" using the same image as is shown in grads.png<br>
<br>3.gif is the same thing as 2.gif only sized as 5000 x 5000 pixels. It shows the overlap is still there, but to much less of an extent relative to the size of the image. This makes me wonder that the overlap is some default like "1 pixel greater no matter what the size" so that it doesn't show up as well for larger images.<br>
<br>Can someone explain to me this behavior and how to keep the color bar colors from overlapping the top line of the color bar in printed images that are obtained using printim? Thanks.<br><br>Jeff Duda<br><font color="#888888"><br>
