[Insight-developers] ITK Dashboard : Failing tests in Applications : BMP and RGB assumption

[Luis Ibanez]

Hi Bill,

I'm tracking the two failing tests from InsightApplications in

                           redwall.kitware.

http://www.cdash.org/CDash/viewTest.php?onlyfailed&buildid=319965

They are:

a) ccvnt_from_bmp_unsigned_char
b) compare_bmp_unsigned_char

The test (b) fails as a secondary effect of (a) failing.

The test (a) fails because the input BMP image is reported to be
an image of RGB  pixels and 3 components, despite the fact that
it has depth 8 bits per pixel.

The tool

InsightApplications/ConvertBetweenFileFormats/castconvert.cxx

doesn't support RGB as a pixel type.

This test started failing on October 2008:

This seems to be related to your modifications of the file

           Insight/Code/IO/itkBMPImageIO.cxx
http://public.kitware.com/cgi-bin/viewcvs.cgi/Code/IO/itkBMPImageIO.cxx?root=Insight&r1=1.28&r2=1.29


Where the BMPImageIO reader, by default declares all images
to be of RGB type, even if they are of 8 bits.

   1) Is this the correct behavior for BMP ?

   2) Is the error in our creation of the BMP file: image_out.bmp  ?

   3) Should we remove this test from Insight Applications


 Thanks for any hints,


      Luis
