[Request for changes - 117] Merge Convert and Rescale applications



Merge the applications Convert and Rescale into new application : DynamicConvert.

Its name, DynamicConvert, is a suggestion.


These two applications (Convert and Rescale) convert the image dynamics, and thus, are very similar.

In order to remove duplicates, these two applications merge.

Implementation details

classes and files

M       Modules/Applications/AppImageUtils/app/otbConvert.cxx
M       Modules/Applications/AppImageUtils/app/otbRescale.cxx
M       Modules/Wrappers/ApplicationEngine/include/otbWrapperTags.h

The Rescale and Convert applications are deprecated and the "Deprecated" tag is added.


M       Modules/Applications/AppImageUtils/app/CMakeLists.txt
A       Modules/Applications/AppImageUtils/app/otbDynamicConvert.cxx

This new application allows to :

  • write the output image in the specified format (pixel type at uint8 by default)
  • apply an input dynamic : histrogram cutting [quantile.high and quantile.low]
  • apply an output dynamic : min and max values [outmin and outmax]
  • choice the rescale type [linear, log2], linear default
  • apply a gamma correction (with the linear rescale mode)
  • mask pixels
  • select channels
  • remove the nodata value in the histogram


M       Modules/Applications/AppImageUtils/test/CMakeLists.txt

Add 3 tests:

  • apTvUtDynamicConvertBasic
  • apTvUtDynamicConvertLog2
  • apTvUtDynamicConvertFloat
