Thanks Bill,

When I tried this code:

<?xml version="1.0" encoding="ISO-8859-1"?>
<isl debug="true" loop="1" offscreen="true" sleep="10.0seconds">

  <image file="${islpath}/${time:yyyyMMdd_HHmm}.png">

</image>

<overlay
    image="${islpath}/${time:yyyyMMdd_HHmm}.png"
    text="${time:HHmm}"
    place="UR"
    anchor="M"
    fontsize="48"
    fontface="Lucida Sans"
    color="white"
    background="black"
    transparency="0" >

</overlay>

</isl>


The image is created (without the overlay) but I get the messages:
Thu Feb 20 18:08:12 EST 2014: Loading bundle: ./test3.xidv
Thu Feb 20 18:08:31 EST 2014: Writing image:./20060912_1400.png
Unknown tag:overlay

When I place just the </image> tag after the block of overlay code I get:

Chris,

This can be done with an isl script that: runs a bundle, saves an image, uses the overlay tag to format and place the time of the data.

Good luck,

Hi folks!

We have a sequence of images that we are trying to prepare for publication using the IDV. We have modified the display list to only display the current time of the image (using %timestamp% with our own format applied). Now what we want to do is to move the location of the text to the upper right quadrant of the image where it doesn't compete with weather that moves into the lower part of the image where the default layout is located.

I don't see any user controlled elements that suggest I can move the location of the text, but we are willing to tweak code to get that done if it is the best solution.

Alternatively, is there a way to have dynamic text in a "Drawing Control" or other text box type of object?

I looked a little at the ISL pages, but didn't see anything that screamed "This is the way!" - I'm overdue for learning how to do some of these things, so I'm all ears!

Thanks in advance for any suggestions.

Best to all,

Chris Herbster
