Overload Details

Overload 1

function WrapPow2(Value, Max: Integer): Integer; overload;

Wraps an integer value to range [0..Max] where Max+1 is a power of two.

Parameter	Type	Description
Value	Integer	Integer value to wrap.
Max	Integer	Inclusive upper bound (where Max+1 is a power of 2, e.g. 3, 7, 15, 255).

Type	Description
Integer	Wrapped integer within range [0..Max].

Overload 2

function WrapPow2(Value, Min, Max: Integer): Integer; overload;

Wraps an integer value to range [Min..Max] where Max-Min+1 is a power of two.

Parameter	Type	Description
Value	Integer	Integer value to wrap.
Min	Integer	Inclusive lower bound.
Max	Integer	Inclusive upper bound (where Max-Min+1 is a power of 2).

Type	Description
Integer	Wrapped integer within range [Min..Max].

Description

WrapPow2 provides accelerated bitwise wrapping for power-of-two dimensions (e.g., textures of width/height 4, 8, 16, 32, 64, 128, 256, 512, 1024). It replaces division/modulo operations with fast bitwise AND masking (Value and Max).
