Operators

---

↑ aktive op sdf 2image fit

Syntax: aktive op sdf 2image fit src [→ definition]

Compresses the input SDF into the range 0..1 and returns the resulting grayscale image.

Input	Description
src	Source image

Examples

@1	@2	aktive op sdf and @1 @2
geometry(0 0 128 128 1)	geometry(0 0 128 128 1)	sdf-fit geometry(0 0 128 128 1)

---

↑ aktive op sdf 2image pixelated

Syntax: aktive op sdf 2image pixelated src [→ definition]

Converts the SDF into a black/white image with pixelated element borders.

Input	Description
src	Source image

Examples

@1	@2	aktive op sdf and @1 @2
geometry(0 0 128 128 1)	geometry(0 0 128 128 1)	sdf-pixelated geometry(0 0 128 128 1)

---

↑ aktive op sdf 2image smooth

Syntax: aktive op sdf 2image smooth src [→ definition]

Converts the SDF into a grey-scale image with anti-aliased element borders.

Input	Description
src	Source image

Examples

@1	@2	aktive op sdf and @1 @2
geometry(0 0 128 128 1)	geometry(0 0 128 128 1)	sdf-smooth geometry(0 0 128 128 1)

---

↑ aktive op sdf not

Syntax: aktive op sdf not src [→ definition]

Returns the inverted input SDF, where inside and outside changed places. This is defined as 1 - SRC.

Input	Description
src	Source image

Examples

@1	aktive op sdf not @1
geometry(0 0 128 128 1)	geometry(0 0 128 128 1) sdf-fit geometry(0 0 128 128 1) sdf-smooth geometry(0 0 128 128 1) sdf-pixelated geometry(0 0 128 128 1)

---

↑ aktive op sdf outline

Syntax: aktive op sdf outline src [→ definition]

Replaces the input SDF with an outlined form, and returns the result.

This is implemented by taking the absolute of the input.

Input	Description
src	Source image

Examples

@1	aktive op sdf outline @1
geometry(0 0 128 128 1)	geometry(0 0 128 128 1) sdf-fit geometry(0 0 128 128 1) sdf-smooth geometry(0 0 128 128 1) sdf-pixelated geometry(0 0 128 128 1)

---

↑ aktive op sdf ring

Syntax: aktive op sdf ring src (param value)... [→ definition]

Combines outlining and rounding to replace the input SDF with an SDF tracing the border at some thickness and returns the result.

The result is annular, i.e. has a ring/onion-like structure.

Note that a thickness of zero devolves this operation to a plain outline.

Input	Description
src	Source image

Parameter	Type	Default	Description
thickness	uint		Desired border thickness.

Examples

@1	aktive op sdf ring @1 thickness 4
geometry(0 0 128 128 1)	geometry(0 0 128 128 1) sdf-fit geometry(0 0 128 128 1) sdf-smooth geometry(0 0 128 128 1) sdf-pixelated geometry(0 0 128 128 1)

---

↑ aktive op sdf round

Syntax: aktive op sdf round src (param value)... [→ definition]

Replaces the input SDF with a more rounded form per the radius, and returns the result.

This is implemented by shifting the input SDF down by the radius.

For a radius > 0 this expands the SDF, making the encoded element rounder. A radius < 0 conversely shrinks the SDF.

To get a rounded SDF at the original size use a pre-shrunken/expanded SDF as the input to compensate the changes made by this operator.

A radius of zero is ignored.

Input	Description
src	Source image

Parameter	Type	Default	Description
radius	uint		Expansion/Shrinkage radius for the SDF.

Examples

@1	aktive op sdf round @1 radius 20
geometry(0 0 128 128 1)	geometry(0 0 128 128 1) sdf-fit geometry(0 0 128 128 1) sdf-smooth geometry(0 0 128 128 1) sdf-pixelated geometry(0 0 128 128 1)
