wcst_import - creates colorPatetteTable automatically if input tif file contains this metadata

[Bang Pham Huu]

Currently, one needs to provide a valid rasql colorPaletteTable as a file to import to coverage's global metadata with general recipe. For example:

"colorPaletteTable": "color_palette_table_rasql_READY.cpt"

In the case of TIFF file, if it contains palette table in band 1, e.g:

Band 1 Block=67x65 Type=Byte, ColorInterp=Palette
  Metadata:
    COLORINTERP=Palette
  Color Table (RGB with 256 entries)
    0: 0,0,0,255
    1: 0,0,0,255
    2: 0,0,0,255
    ...

wcst_import should collect it by default ("colorPaletteTable" option is not specified in the ingredient file) or in case

"colorPaletteTable": "auto"

and transfer it to valid rasql colorPaletteTable and import to coverage's metadata.

In case, one does not want to add this colorPaletteTable, then he can set in the ingredient file:

"colorPaletteTable": ""
