.raw file problem in DrishtiImport v2.6.4 #23

Open FrankFR opened 6 years ago

FrankFR commented 6 years ago

Hello everyone,

When importing data from a .raw file the slices in Z and X direction look as expected, but the y-slices behave strangely (see attached images of 4 consecutive Y-slices). Every second slice looks as if the byte order is wrong. I used data from completely different CT-setups. The used .raw files are either 'uint16 little endian' or '32-bit float' format and I am using Drishti for Windows. Despite this, I am able to create a .pvl.nc file and the rendered volume looks totally fine. As I have no idea what the problem could be, I'd appreciate every contribution.

Regards,

Frank

P.S.: I just downloaded AMIDE to check if the slice problem also occurs there, but it looks normal.

Hi Frank, This is a bug in Drishti Import for extraction and display of slice in Y axis, but as you have seen it does not affect the processing and display in the renderer.

Cheers, Ajay
