Class ICC_ProfileGray

public float[] getMediaWhitePoint()

Returns a float array of length 3 containing the X, Y, and Z components of the mediaWhitePointTag in the ICC profile.

public float getGamma()

Returns a gamma value representing the tone reproduction curve (TRC). If the profile represents the TRC as a table rather than a single gamma value, then an exception is thrown. In this case the actual table can be obtained via getTRC(). When using a gamma value, the PCS Y component is computed as follows:

                          gamma
         PCSY = deviceGray

public short[] getTRC()

Returns the TRC as an array of shorts. If the profile has specified the TRC as linear (gamma = 1.0) or as a simple gamma value, this method throws an exception, and the getGamma() method should be used to get the gamma value. Otherwise the short array returned here represents a lookup table where the input Gray value is conceptually in the range [0.0, 1.0]. Value 0.0 maps to array index 0 and value 1.0 maps to array index length-1. Interpolation may be used to generate output values for input values which do not map exactly to an index in the array. Output values also map linearly to the range [0.0, 1.0]. Value 0.0 is represented by an array value of 0x0000 and value 1.0 by 0xFFFF, i.e. the values are really unsigned short values, although they are returned in a short array.
