Labview crashes when creating large image files

Question

I have a problem with Labview 6.0.2( I've tested evaluation version 7.0 too).
I'm constructing a very large image, for example: 4500x4500 pixels. Labview crashes when converting the pixture to a pixmap. The image is fully constructed on my screen (in a picture control), but when converting it to a pixmap (for saving the image in a known format (bmp, jpg, tiff)), Labview crashes.
I did some testing and when the number of pixels exceeded the limit of 2^24(16777216), the file 'image.cpp' crashes on line 1570. The vi to convert it to a pixmap is: P'icture to pixmap.vi'
Does someone know a workaround for this problem? Or is there a fix for it?
Thank you!

Answer 1

I've tested the 6i version of my VI in Labview 7.0 evalutation version. It raised an error but not the same error:
d:\lvworm\src\lvsource\compatexport.cpp(37) : DAbort: Called a routine not in the compatibility LVRT table
$Id: //labview/branches/Wormhole/dev/lvsource/compatexport.cpp#11 $
0x004BD4CB - LabVIEW_Eval + 0
0x0EB710D9 - lvs248 + 0
0x094C87A0 - + 0
So i replaced the picture VI's with the 7.0 evalutation version VI's, and it worked. It is now possible for me to construct very large image files!
I see no attached VI to test. But i guess it is also solved in Labview 7.0
I used this file to convert the picture to image data:
C:\Program Files\National Instruments\LabVIEW 7.0 Evaluation\vi.lib
\picture\pictutil.llb\Picture to Pixmap.vi
And this file to convert image data to bmp:
C:\Program Files\National Instruments\LabVIEW 7.0 Evaluation\vi.lib\picture\bmp.llb\Write BMP File.vi
I guess i have to write a workaround for this problem:
divide the picture in blocks of 4096 x 4096 and then merge the image data arrays of the bloks together.
