Hi Arnaud, that should be possible. We are using it with some datasets. Let me quote an example of a property file I have around:
Name=RGB Levels=0.2,0.2;0.4,0.4;0.8,0.8 1.6,1.6;3.2,3.2;6.4,6.4 12.8,12.8;25.6,25.6;51.2,51.2 102.4,102.4;204.8,204.8;409.6,409.6;819.2,819.2;1638.4,1638.4;3276.8,3276.8;6553.6,6553.6 LevelsNum=4 Envelope2D=-2000000,3000000 2000000,7000000 (I have copied your :-) ) LevelsDirs=0 1 2 3 Note the ";" char usage to specify available resolutions within the same pyramid level whilst the " " (whitespace) still separates different levels I have 4 levels in my pyramid. the first level has resolutions 0.2,0.2;0.4,0.4;0.8,0.8 So a 20 cm high res and 2 overviews (40 cm, 80 cm) the second level has resolutions 1.6,1.6;3.2,3.2;6.4,6.4 So a 1.6 m res plus 2 overviews (3.2 m and 6.4 m) ..... Last level is different 102.4,102.4;204.8,204.8;409.6,409.6;819.2,819.2;1638.4,1638.4;3276.8,3276.8;6553.6,6553.6 it has 102.4m res + 6 overviews. Does it helps?
