Hi, this error reports that the input codestream has less than three while the PPM format needs three components.
I have looked into the attached codestream (a1_mono.j2k) and image file (a1_mono.ppm).
a1_mono.ppm is actually in .pgm format.
I have tried the following:
./open_htj2k_dec -i images/a1_mono.j2k -o tmp.pgm
then I got tmp_00.pgm and it seems that the codestream has been successfully decoded.
So, my answer is that you have to use .pgm as the extension of the output image!
