Re: [idvusers] overlays - isl


How do i add an overlay to a image in isl. I have read though the
manuel, but can't get it to work.
Below is the script i would like to add it to <?xml version="1.0" encoding="ISO-8859-1"?>
<isl debug="true" loop="1" offscreen="true" sleep="60.0minutes">
<bundle clear="true" file="${islpath}/MSLP_06_GFS.xidv" wait="true"
width="500" height="420"/> <image file="C:\MODELGFS05_GRIB2\DATA\UK\IMAGES\MSLP_06_GFS.png"/>
</isl>

Hi Ian,
The user guide has a section on this:
http://www.unidata.ucar.edu/software/idv/release/nightly/docs/userguide/isl/ImagesAndMovies.html
And there are examples in the workshop materials:
http://www.unidata.ucar.edu/software/idv/docs/workshop/isl/ManipulatingImages.html

Basically change your image tag to be:
<image file="C:\MODELGFS05_GRIB2\DATA\UK\IMAGES\MSLP_06_GFS.png">
<overlay image="http://www.unidata.ucar.edu/software/idv/logo.gif"; place="LL,10,-10" anchor="LL"/>
</image>


This will place the image in the lower left of the base image.
