[Geoserver-devel] PyramidBuilder + no-data color

Hi !

I am using Geoserver to serve USRP datas.
I am actually doing the following steps :

  • converting an reprojecting USRP to Geotiff using gdal_translate and gdalwarp,
  • creating an image mosaic for the different USRP making an unique layer using the MosaicIndexBuilder
  • creating an image pyramid using the PyramidBuilder.

My problem appears in the last step :
I convert and reproject the USRP with the parameters -expand rgba and -dstnodata “255 255 255 0” to have no black areas during the USRP overlaying.
It works fine, but the PyramidBuilder generates some black areas to complete the picture (during CoverageTiling). I would like to change the black in another background color, because I don’t want black to be transparent when serving with geoserver ! (i would prefer something like e000ff for instance !!)

Thanks in advance
cheers,
Thomas
