# This script will be used to make sure we never introduce a regression on any
|
|
# of the nonregression file.
|
|
#
|
|
# The approach is relatively simple, we compute a md5sum for each of the decode
|
|
# file. Anytime the md5sum is different from the reference one, we assume
|
|
# something went wrong and simply fails. of course if could happen during the
|
|
# course of openjpeg development that the internals are changed that impact the
|
|
# decoding process that the output would be bitwise different (while PSNR would
|
|
# be kept identical).
|
|
|
|
# Another more conventional approach is to store the generated output from
|
|
# openjpeg however storing the full generated output is generally useless since
|
|
# we do not really care about the exact pixel value, we simply need to known
|
|
# when a code change impact output generation. furthermore storing the
|
|
# complete generated output file, tends to make the svn:/openjpeg-data really
|
|
# big.
|
|
|
|
# This script expect two inputs
|
|
# REFFILE: Path to the md5sum.txt file
|
|
# OUTFILENAME: The name of the generated file we want to check The script will
|
|
# check whether a PGX or a PNG file was generated in the test suite (computed
|
|
# from OUTFILENAME)
