[magick-users] [q] how to remove bKGD chunk from PNG file

[Traut]

Hi

      How I can get rid of bKGD chunk in PNG file? command line properties?
I need them to know what to look in JMagick API docs.

      This chunk appears when I use imagemagick libs through JMagick for
reading/writing file (without any converting).
      Original image chunks: IHDR, gAMA, tEXt, IDAT, IEND
      Processed image: IHDR, gAMA, bKGD, pHYs, IDAT, tEXt, IEND

Thank you in advance
