you're not using web URLs for their full paths in the command.</span></p>

format of the image (bit) is causing issues.</span></p>
<p class="MsoNormal"><span style="font-size: 11pt; color: rgb(31, 73, 125);">- I'm assuming -t 0 applies to the output being placed on the
background, and not on the background itself. It doesn’t make sense that
it would be that way, but perhaps having the -t 0 option before the -b command
would make a difference?</span></p>

<p class="MsoNormal"><span style="font-size: 11pt; color: rgb(31, 73, 125);">With this said, I believe I had trouble doing this myself. I
ended up writing external code to do some things similar. But you may want to
look at OpenGrads' gxyat command… I don't recall if it has a background
image option, but it may be something to check out. </span></p></div></div></blockquote><div><br>At this it does handle the background image automatically, you will need to use image magick to blend the 2 images.<br> </div>
