Is Proxel X3F Tools (build 041) compatible with Merrill-generation X3F?

folks,

I"m trying to use Proxel X3F Tools (x3f_extract/x3f_io_test, build 041)
for Merrill-generation X3F but having difficulty to understand its output.

I would like to know if there is any tips to use the tool properly.

(1) x3f_extract

  • run "x3f_extract.exe -tiff -gamma 2.2 -min 0 -max 4095 INPUTFILE.X3F"
  • generated TIFF file's color representation looks very insane, as if white-balance information was handled mistakenly. Like, I took the photo under "cloudy/overcast", but process that image by SPP white-balance "Tungsten" or something. 
  • I feel it is different from the README description "NOTE - the result is not a regular RGB image - its in the X3F "color space" - so it contains faulty colors." thing. I tried x3f_extract on SD14 X3F, so I know that it means.

(2) x3f_io_test

  • According to README, If I run "x3f_io_test file.x3f outfile1.x3f outfile2.x3f", then three files should be identical. (or at least, infile and outfile1 should be identical?)
  • If it is still true for Merrill-generation, I'm having unexpected result.
  • Run "x3f_io_test.exe SDIM0027.X3F outfile1.x3f outfile2.x3f" then result is,

$ md5sum.exe SDIM0027.X3F outfile1.x3f outfile2.x3f
ae7a000fcd8c4ee94c8e32c3291cf01f *SDIM0027.X3F
602787ac772f2f34c6026ade6c9b1ad8 *outfile1.x3f
602787ac772f2f34c6026ade6c9b1ad8 *outfile2.x3f

oufile1 and outfie2 are the same, but it's different from original X3F.
I have x3f_io_test output here, but it has certain line number, and I was not sure it's appropriate to do just copy&paste on this forum.
If' it's OK, I can post it immediately.

(3) So what?
I think, possible answer for my question is,
a) it is expected, and correct output on build 041
b) my command usage is not correct. Use it right.
c) X3F tools build 041 is not 100% compatible with Merrill-generation X3F yet.

Which is correct?
Any comments are welcome.

Thank you very mich.
