Hello,
Thoroughly searched through the archives before posting this question with
no luck. I would think someone's ran into a similar problem before.
Goal: Generate a 960x720 satellite image centered over the U.S. which
exactly matches an existing 960x720 image of the US. This image needs to be
automatically generated every ~15 minutes as new satellite data comes in.
I was able to manually create the EXACT image needed in IDV following the
steps below. When I tried to save all of the steps made as an xidv bundle
and create a simple ISL script, it did not save in full screen mode, but
instead saved the image in the display panel dimensions.
STEP1: Create custom Projection named "custom_us"
Type: Stereographic, False Easting: 0, False Northing: 0, Scale: 1, Tangent
lat: 90.0, Tangent lon: -96.0
STEP2: Move the bounding box of the projection by editing
".undata/idv/DefaultIdv/projections.xml" <after hours of trial and error>
<?xml version="1.0" encoding="ISO-8859-1"?>
<object class="java.util.ArrayList">
<method name="add">
<object class="ucar.unidata.geoloc.projection.Stereographic">
<property name="Scale">
<double>1.000</double>
</property>
<property name="TangentLon">
<double>-96.0</double>
</property>
<property name="DefaultMapArea">
<object class="ucar.unidata.geoloc.ProjectionRect">
<constructor>
<double>-4569.999999999999</double>
<double>-10740.999999999999</double>
<double>4629.999999999999</double>
<double>-1491.000000000001</double>
</constructor>
</object>
</property>
<property name="Name">
<string><![CDATA[custom_us]]></string>
</property>
</object>
</method>
</object>
STEP3: Add Directory with satellite data using "Data Choosers", Create
Display
STEP4: Select View, Properties
- uncheck (all boxes), set Full Screen Dimensions (960 x 720)
STEP5: Select Projections, Predefined, "custom_us"
STEP6: Zoom in Exactly 4 times
STEP7: Select View, Full Screen
STEP8: Select View, Capture, Image, Name it "test.gif" --- PERFECT!!!
STEP9: Files, Save As "custom_us_satellite.xidv"
STEP10: Create a simple .isl script "custom_us_satellite.isl"
<isl debug="true" offscreen="false">
<bundle file="custom_us_satellite.xidv"/>
<pause/>
<image file="custom_us_satellite.gif"/>
</isl>
STEP11: Run isl script to generate gif image. Result: creates an image NOT
960 x 720 pixels, instead it creates an image which is the size of the
display panel (1164 x 1002 pixels) and is clearly distorted from the view I
need.
Thanks in advance for your help,
Evan Lowery
