Tilman Hausherr commented on PDFBOX-2553:
-----------------------------------------
new code:
{code}
public float[] toRGB(float[] value)
{
float a = value[0];
float b = value[1];
float c = value[2];
Matrix matrix = getGammaMatrix();
PDGamma gamma = getGamma();
float x = (float) (matrix.getValue(0, 0) * Math.pow(a, gamma.getR()) +
matrix.getValue(0, 1) * Math.pow(b, gamma.getG()) + matrix.getValue(0, 2) *
Math.pow(c, gamma.getB()));
float y = (float) (matrix.getValue(1, 0) * Math.pow(a, gamma.getR()) +
matrix.getValue(1, 1) * Math.pow(b, gamma.getG()) + matrix.getValue(1, 2) *
Math.pow(c, gamma.getB()));
float z = (float) (matrix.getValue(2, 0) * Math.pow(a, gamma.getR()) +
matrix.getValue(2, 1) * Math.pow(b, gamma.getG()) + matrix.getValue(2, 2) *
Math.pow(c, gamma.getB()));
return CIEXYZ.toRGB(new float[] { x, y, z });
}
{code}
will do tests and have sleep first before committing.
