public static class ImmutableAffineTransform.Companion

Summary

Public methods
`static final @NonNull ImmutableAffineTransform`	`scale(float scaleFactor)` Returns a transformation that scales in both the x- and y-direction by the given `scaleFactor`, centered about the origin.
`static final @NonNull ImmutableAffineTransform`	`scale(float xScaleFactor, float yScaleFactor)` Returns a transformation that scales in both the x- and y-direction by the given pair of factors; `xScaleFactor` and `yScaleFactor` respectively, centered about the origin.
`static final @NonNull ImmutableAffineTransform`	`scaleX(float scaleFactor)` Returns a transformation that scales in the x-direction by the given factor, centered about the origin.
`static final @NonNull ImmutableAffineTransform`	`scaleY(float scaleFactor)` Returns a transformation that scales in the y-direction by the given factor, centered about the origin.
`static final @NonNull ImmutableAffineTransform`	`translate(@NonNull Vec offset)` Returns a transformation that translates by the given `offset` vector.

Extension functions
`static final ImmutableAffineTransform`	`AndroidGraphicsConverter.from( @NonNull ImmutableAffineTransform.Companion receiver, @NonNull Matrix matrix )` Constructs an `ImmutableAffineTransform` with the values from `matrix`.

Public methods

scale

Added in 1.0.0-alpha05

public static final @NonNull ImmutableAffineTransform scale(float scaleFactor)

Returns a transformation that scales in both the x- and y-direction by the given scaleFactor, centered about the origin.

scale

Added in 1.0.0-alpha05

public static final @NonNull ImmutableAffineTransform scale(float xScaleFactor, float yScaleFactor)

Returns a transformation that scales in both the x- and y-direction by the given pair of factors; xScaleFactor and yScaleFactor respectively, centered about the origin.

scaleX

Added in 1.0.0-alpha05

public static final @NonNull ImmutableAffineTransform scaleX(float scaleFactor)

Returns a transformation that scales in the x-direction by the given factor, centered about the origin.

scaleY

Added in 1.0.0-alpha05

public static final @NonNull ImmutableAffineTransform scaleY(float scaleFactor)

Returns a transformation that scales in the y-direction by the given factor, centered about the origin.

translate

Added in 1.0.0-alpha05

public static final @NonNull ImmutableAffineTransform translate(@NonNull Vec offset)

Returns a transformation that translates by the given offset vector.

Extension functions

AndroidGraphicsConverter.from

Artifact: androidx.ink:ink-geometry

View Source

public static final ImmutableAffineTransform AndroidGraphicsConverter.from(
    @NonNull ImmutableAffineTransform.Companion receiver,
    @NonNull Matrix matrix
)

Constructs an ImmutableAffineTransform with the values from matrix.

If matrix is not an affine transform, returns null instead.

Performance-sensitive code should use the populateFrom overload that takes a pre-allocated MutableAffineTransform, so that the instance can be reused across multiple calls.

Java callers should prefer AndroidGraphicsConverter.createAffineTransform(Matrix) (createAffineTransform).
