bad captureImage

Post by joleenf »

Hi,

This sequence:

Code: Select all


data = loadGrid('/Users/joleenf/CG_ABI-L2-CMIPM1-M3C13_G16_s20182822359280_e20182822359350_c20182830001296.nc', field='CMI')

panel = buildWindow(height=2160, width=1920)

latitude=26.59
scale=2.0
longitude=86.49

ir_min, ir_max = getMinMax(data)

layer=panel[0].createLayer('Image Display', data)

panel[0].setProjection(layer)
panel[0].setCenter(latitude, longitude)
panel[0].setScaleFactor(scale)

panel[0].captureImage('/Users/joleenf/data/meso1.png', createDirectories=True)


Causes either a failure of
javax.media.j3d.BadTransformException: TransformGroup: non-affine transform

or no message at all, but no image either...

The problem (I think) is that the longitude value is not in the projection. This is causing a problem with setCenter, but the code proceeds forward to the captureImage portion. Even though the image cannot and does not re-center, it seems that the image cannot be captured once this error occurs. Consequently, the image capture hangs.

Hi Joleen,

Thanks for reporting this, I'm replicating the problem. This looks to be the same bug as Inquiry 2478. I added a note to the inquiry that you ran into the bug again and I added a link to this forum post.

If I come up with a workaround for this, I'll let you know.

Thanks,
Bob

I think either we can fix setCentetLatLon method
by giving appropriate warning or a debug msg and not
keeping the image as it is without doing paning if center
lat/lon is not in the image. That makes some sense, I hope.

Hi Ghansham,

Yes, that makes sense and sounds like a reasonable way to solve the problem. I’ve added a note to the inquiry with your suggestion.

Thanks,
Bob
