Crash in Image.translate()

[Andres.Pozo]

Testing the FFTregistration script I found a crash in a call to the function Image.translate. I have written a short script that calls to that function and it also fails.
The tests have been done in Windows Vista 32 and Windows 7 64.

Code: [Select]

#include <pjsr/UndoFlag.jsh>

var w = ImageWindow.activeWindow;
var v = w.mainView;
v.beginProcess( UndoFlag_NoSwapFile );
v.image.translate(5,5);
v.endProcess();

Sometimes the application crashes too.

Hi Andres
For translations use the module I wrote. By Juan's suggestion, it includes a wavelets filtering, that may aid the registration process. I use the same algorithm every day for microscopic images, and it works quite well.

Your module doesn't work with my images  so I was trying the new script from Juan.
Anyway, the JS engine is crashing in my machines. Could anybody try the simplified script in Windows to confirm the bug?

Juan has asked in another thread for an image in which this script fails. I have attached a crop from a Canon 400D shot converted to TIFF.

I have tried again with your module an the results are much better than the last time I used it (last august, I think). I have been able to register my images from the July total eclipse 

Thanks Carlos for your good work!!

Andrés,

I have confirmed this bug on Windows (32-bit and 64-bit versions). I'm working to fix it ASAP and will publish an update as soon as I get it fixed.

Thanks for reporting.

[Juan Conejero]

Fixed!

Actually, the same problem occurs with most interpolating geometric transformations in the PJSR (translation, resample, rotation, etc.). The cause of this problem is NOT in my code, but in M$'s particular interpretation of the C++ language... better stop writing at this point  Suffice it to say that the same code works perfectly when compiled with g++ (FreeBSD, Linux and Mac OS X), just because g++ is a good standards-compliant compiler.

Anyway, the problem is now fixed. I'll publish an update to the Windows versions of PixInsight Core ASAP.

[Andres.Pozo]

The script that I posted in the first message still fails. Worse, it now crashes PixInsight.

Andrés,

Este bug en su 'encarnación' actual es el mismo que éste.

Estoy trabajando en ello...

Gracias Juan!!

[Juan Conejero]

De nada, es mi trabajo

Una pregunta, estás con la versión de 32 bits o con la de 64? No debería ocurrir con la de 32...

[Andres.Pozo]

Pues me ha fallado en 32bits...

Hi,

This bug has been fixed in PixInsight Core 1.7.0.696. The new version is now available as a regular update for Windows x86 and x64.

Thanks for your patience!
