Methods

fromByte	self.fromByte(float) -> float.
fromByteSingle	self.fromByte(float) -> float.
fromFloat	fromFloat(src, alpha) -> float list.
isLinear	self.isLinear() -> True if toByte(x) appears to return x*255, False otherwise.
isZero	self.isZero() -> True if toByte(0) returns a value <= 0, False otherwise.
toByte	self.toByte(float) -> float.
toByteSingle	self.toByte(float) -> float.
toFloat	toFloat(src, alpha) -> float list.

fromByte(float) → float.

Converts byte values in the range 0-255 to floating point.

fromByteSingle()

self.fromByte(float) -> float.

Converts byte values in the range 0-255 to floating point.

fromFloat(src, alpha) → float list.

Convert a sequence of floating-point values to from_byte(x*255). Alpha is an optional argument and if present unpremultiply by alpha, convert, and then multiply back.

isLinear() → True if toByte(x) appears to return x*255, False otherwise.

isZero() → True if toByte(0) returns a value <= 0, False otherwise.

toByte(float) → float.

Converts floating point values to byte values in the range 0-255.

toByteSingle()

self.toByte(float) -> float.

Converts floating point values to byte values in the range 0-255.

toFloat(src, alpha) → float list.

Convert a sequence of floating-point values to to_byte(x)/255. Alpha is an optional argument and if present unpremultiply by alpha, convert, and then multiply back.
