Hello 

 As far I know, the bands of a multiplanar Image ( planarConfiguration tag =
 2)  should be written one after the other. But for me, this is not clear.
 Please, let me write an example to explain my understanding:  

    We have an image withe the following parameters:

     Lines = 6000 
     Columns = 1500 
     The image has 5 different bands ( samplePerPixel = 5 ), and
     planarconfiguration = 2
      The image is stripped, with the parameter RowsPerStrip = 100, so there
      are 60 strips.

      If I want to read this image using the function readEncodedStrip from
      libtiff library. The number of strips to be read is 5*60? The first 60
      strips corresponds to the first band, the next 60 strips corresponds
      to the second band and so on. Are this statements correct?

     For Tiled image the approach should be similar, isn't it?

Thank you very much!!


Best regards,

Jorge
