error when creating an RGB layer

[hproe]

Hi -

Since the 1.5beta2 build of Sat 13 December my sipts creating RGB image sequences quits when, after having stored all RGB frames in variable imageSeq, creating the RGB layer like

Code: Select all

 imageLoop=makeTimeSequence(imageSeq)
 imLayer=imDisplay.createLayer('RGB Composite',imageLoop)

The error message issued is:

Code: Select all

visad.VisADException: SingleBandedImageImpl: Range must be a RealType or RealTupleType with one component

I have attached a sample script that creates a sequence of Dust RGBs. Up Friday build everything worked as expected.

cheers, HP

Hi HP,

We have updated the VIIRS plugin and you'll need to uninstall your current version install the new version.

From the Main Menu, Tools ->Plugins->Manage uninstall the current version. Restart.
From the Main Menu, Tools ->Plugins->Manage->Miscellaneous (open the tree) install the current version. Restart.

Let us know if that works for you.

Hi HP,

There will be one additional source code module (not plugin) included in tonight's nightly to address your problem.

Hi HP,

This is unrelated to the VIIRS plugin actually. (However, you'll probably want to follow Rick's suggestion anyway if you're doing any work with the VIIRS plugin).

We made some fairly substantial low-level changes to the scripting stuff last week which broke createLayer's compatibility with the 'makeTimeSequence' function.

I just committed a fix, and I expect your script will work again in tomorrow's nightly. Let me know!

Happy holidays!

Hi Mike and Rick -

I have seen and installed the VIIRS update - thankfully you get a warning when starting up the first build containing the new version! Looks like it is working well. Another thank for (hopefully) fixing the broken createLayer stuff.

cheers, HP

In today's build createLayer works again for RGB, Mike!
