I believe it is due to the expanded color map; the way that the anti-aliasing algorithm blends colors into the background introduces many new colors (in addition to any colors that are defined by the GrADS user). If you are concerned about image file size, then you can convert it to JPEG format and use compression, or try another tool called pngquant (<a href="http://pngquant.org" target="_blank">pngquant.org</a>) which reduces the size of PNG images. <div>

One thing we are finding with it though is that the file sizes of the png's being outputted are much larger than on previous versions, a typical chart previously would have been 80-120kb, now it's 500-600kb. Is there any possible way to reduce that back?<div>
