Constants' Details
HALFFLOAT
const byte HALFFLOAT =0; Description 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.
FLOAT
const byte FLOAT =1; Description 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.
DOUBLE
const byte DOUBLE =2; Description 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.
