Method Detail

getSRGB

public static ColorSpace getSRGB()

getSRGBLinear

public static ColorSpace getSRGBLinear()

getDisplayP3

public static ColorSpace getDisplayP3()

convert

public Color4f convert(ColorSpace to,
                       Color4f color)

isGammaCloseToSRGB

public boolean isGammaCloseToSRGB()

Returns:

true if the color space gamma is near enough to be approximated as sRGB

isGammaLinear

public boolean isGammaLinear()

Returns:

true if the color space gamma is linear

isSRGB

public boolean isSRGB()

Returns true if the color space is sRGB. Returns false otherwise.

This allows a little bit of tolerance, given that we might see small numerical error in some cases: converting ICC fixed point to float, converting white point to D50, rounding decisions on transfer function and matrix.

This does not consider a 2.2f exponential transfer function to be sRGB. While these functions are similar (and it is sometimes useful to consider them together), this function checks for logical equality.

_nGetFinalizer
