Public constructors
Transformation
Transformation()
Creates a new transformation with alpha = 1 and the identity matrix.
Public methods
clear
open fun clear(): Unit
Reset the transformation to a state that leaves the object being animated in an unmodified state. The transformation type is TYPE_BOTH by default.
compose
open fun compose(t: Transformation!): Unit
Apply this Transformation to an existing Transformation, e.g. apply a scale effect to something that has already been rotated.
| Parameters | |
|---|---|
t |
Transformation!: |
getMatrix
open fun getMatrix(): Matrix!
| Return | |
|---|---|
Matrix! |
The 3x3 Matrix representing the transformation to apply to the coordinates of the object being animated |
getTransformationType
open fun getTransformationType(): Int
Indicates the nature of this transformation.
| Return | |
|---|---|
Int |
TYPE_ALPHA, TYPE_MATRIX, TYPE_BOTH or TYPE_IDENTITY. |
set
open fun set(t: Transformation!): Unit
Clones the specified transformation.
| Parameters | |
|---|---|
t |
Transformation!: The transformation to clone. |
setAlpha
open fun setAlpha(alpha: Float): Unit
Sets the degree of transparency
| Parameters | |
|---|---|
alpha |
Float: 1.0 means fully opaque and 0.0 means fully transparent Value is between 0.0 and 1.0 inclusive |
setTransformationType
open fun setTransformationType(transformationType: Int): Unit
Sets the transformation type.
| Parameters | |
|---|---|
transformationType |
Int: One of TYPE_ALPHA, TYPE_MATRIX, TYPE_BOTH or TYPE_IDENTITY. |
toShortString
open fun toShortString(): String!
Return a string representation of the transformation in a compact form.
toString
open fun toString(): String
| Return | |
|---|---|
String |
a string representation of the object. |
