Hi

Anyone who can explain me why the atalasoft-lzw compression gives such a poor results. Via the code beneath I saved one of my standard files (flamingo.tif) two times; first uncompressed and then lzw-compressed. Here are the results of the jury:

• flamingo.tif  44KB  (the original file)
• flamingo_atalasoft_uncompressed.tif  39KB
• flamingo_atalasoft_lzw  40KB (even worser then the uncompressed coding!!!)
• flamingo_lzw  2KB  (compressed with an lzw-algorithme I programmed my own)

My code:

static void Main(string[] args)

  string fnsrc = "c:\\images\\flamingo.tif";

  string fndst_tif_unc = "c:\\images\\flamingo_atalasoft_uncompressed.tif";

  string fndst_tif_lzw = "c:\\images\\flamingo_atalasoft_lzw.tif";

  try

    Atalasoft.Imaging.AtalaImage im_src = new Atalasoft.Imaging.AtalaImage(fnsrc);

    im_src.Save(fndst_tif_unc, new TiffEncoder(TiffCompression.NoCompression), null);

    im_src.Save(fndst_tif_lzw, new TiffEncoder(TiffCompression.Lzw), null);

  catch (Exception ex)

     Console.WriteLine(ex.Message);
