bool is_approximate( )
Java: boolean Is_approximate( )
[Declared in "../apps/compressed_io/jp2.h"]
Returns true if the last call to init was successful and the associated colour transformations are only approximate. This may happen if the call to init indicated that fast approximations are preferred, or if an exact conversion cannot be performed. For example, if the original colour space is JP2_CMYK_SPACE or JP2_CMY_SPACE, there is not sufficient information to know exactly how to convert to sRGB, but inverting the C, M and Y components should give a recognizable rendition.
