Variable Documentation

DOUBLE

const byte DOUBLE =2

IEEE double format.

The color components are stored in the IEEE double-precision floating point format, i.e. in a 64 bit value, with 16 bit exponent, 47 bit mantissa and a sign bit.

FLOAT

const byte FLOAT =1

IEEE float format.

The color components are stored in the IEEE single-precision floating point format, i.e. in a 32 bit value, with 8 bit exponent, 23 bit mantissa and a sign bit.

HALFFLOAT

const byte HALFFLOAT =0

Half-float format.

The color components are stored in the half-float format, i.e. in a 16 bit value, with 5 bit exponent, 10 bit mantissa and a sign bit. See also OpenEXR for a format employing half-floats.
