◆ loadJpeg12QuantizationTables()

bool ossimJpeg12NitfReader::loadJpeg12QuantizationTables ( jpeg12_decompress_struct & cinfo ) const

protected

Loads one of the default tables based on COMRAT value.

Returns: true if comrat had valid table value(1-5) and table was loaded, false if COMRAT value did not contain a valid value. Will also return false if there is already a table loaded.

Note

COMRAT is nitf compression rate code field:

"00.2" == default compression table 2
"00.5" == default compression table 5 and so on.
