Can't import RGB image as slice of 3D object

[mackoel@…]

Create collection for 3D RGB object:

rasql —user rasadmin —passwd rasadmin -s localhost -q 'create collection img_3d RGBSet3'

Insert an empty object:

rasql —user rasadmin —passwd rasadmin -s localhost -q
'insert into img_3d values marray m in [0:0,0:0,0:0] values struct{0c,0c,0c}'

rasql —user rasadmin —passwd rasadmin -s localhost -q 'update img_3d as s set s[2047:2047,1215:1215,133:133] assign marray m in [2047:2047,1215:1215,133:133] values struct{0c,0c,0c}'

Try to update the slice:

rasql —user rasadmin —passwd rasadmin -s localhost -q
'update img_3d as v set v[0:2047,0:1215,0] assign inv_tiff( $1 )'
—file img_3d_slice.tif —mddtype RGBImage —mdddomain [0:2047,0:1215]

Alireza, can I just suggest to also try to insert this image in a 2D collection. It's possible that the tiff converter has problems reading it or something similar, so it doesn't hurt to make sure that it works for 2D.

[Dimitar Misev]

So we discovered the error is specific to --mddtype RGBImage --mdddomain [0:2047,0:1215], not whether it's 2D/3D.

The ultimate solution is to fix ticket #119 probably, but fixing the segfault when using these options should be also done.

I found a workaround, casting to char seems to work ok, even though technically it should be casted to RGBPixel, which doesn't work at the moment (#119). So this works:

rasql -q 'update test as v set v[0:2047,0:1215,0] assign (char) inv_tiff( $1 )' --file img_3d_slice.tif
