HDMake Dest Parameter RRS feed

  • Question

  • Hi,

     

    whenever I use:

    Code Snippet
    hdmake -src uhr.jpg -dst uhr quality(1) -xmlflat uhr.xml -html uhr.html

     

     

    the resulting view is blurry and not sharp, the tiles are very small, it not usable.

     

    when I instead use:

    Code Snippet

    hdmake -src uhr.jpg -xmlflat uhr.xml -html uhr.html

     

     

    everything is ok.

     

    So the difference is the -dest parameter. But this one is very important for me.

     

    What am I doing wrong? Or what can I do, to bypass this behaviour?

     

    Thank you very much.

  • Are you putting the text 'quality()' in the parameter?  That may be the issue. 

     

    The quality parameter is a number between 0 and 1 (below 0.4 the results start to be too compressed). Here are a couple examples of how to set it:

     

    hdmake -src uhr.jpg -dst uhr 1 -xmlflat uhr.xml -html uhr.html

     

    hdmake -src uhr.jpg -dst uhr 0.8 -xmlflat uhr.xml -html uhr.html

     

    The first encodes a tile-set with quality of 1, which is uncompressed, but results in large tile sizes.  The second with a quality of 0.8 compressed and with tile sizes reasonable for internet streaming.

     

    For 8bit/component data I usually choose quality between .7 and .85

    For 16bit/32bit data I usually choose quality between 0.45 and 0.65
