Re: [idvusers] Automated/dynamic text object?

Chris,
The overlay tag goes inside the image tag. Looking at some of my scripts, I see that I used the movie tag instead of the image tag. (Movies can be one frame!) Can't remember why I did this; but it definitely works.

Thanks Bill,
I was able to get a basic script to work that saved an image. When I tried to add the overlay tag I broke what had been working. Does the overlay tag live in a block before, after or inside of the image tag?
It seems that I get errors about tags not being closed now. (isl, overlay, image) I can generate a number of errors, depending on the nesting of these things. Alternatively, am I being dense? Does the overlay tag replace the image tag to create the image with that overlay? 


When I tried this code:

<?xml version="1.0" encoding="ISO-8859-1"?>
<isl debug="true" loop="1" offscreen="true" sleep="10.0seconds">
<bundle clear="true" file="${islpath}/test3.xidv" height="600" wait="true" width="800"/> 

  <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:

----
When I stick the code for the image tag inside of the overlay block I get the "Unknown tag" error and no image is created.
When I stick the code for the image after the overlay code then I get the unknown tag error and no image is generated. 

Thanks to anyone who can help,

CH
