Scale
|
This structure represents scaling
transformations (scale vectors) in 2D space. The Scale2d may be
viewed as an array[2] of doubles. Array indicies: * 0 - Scale
factor for the x-axis. * 1 - Scale factor for the y-axis.

Scale2d(Double) | Constructor for the Scale2d class. Creates a scale transformation with the specified factors for x- and y-axes. |
|
|
Scale2d(Double, Double) | Constructor for the Scale2d class. Creates a scale transformation with the specified factors for x- and y-axes. |
Properties
| Name | Description | |
|---|---|---|
|
Coordinate | Property that represents a scale factor at the specified index. |
|
|
X | Property that represents a scale factor for the x-axis. |
|
|
Y | Property that represents a scale factor for the y-axis. |
Methods
| Name | Description | |
|---|---|---|
|
|
Equals | Checks objects for equality. (Overrides ValueTypeEquals(Object)) |
|
ExtractScale | Returns the scale that corresponds to the length of the column vectors of the specified transformation matrix. |
|
|
GetHashCode | Retrieves the object hash code. (Overrides ValueTypeGetHashCode) |
|
|
GetMatrix | Returns the transformation matrix equivalent to this scale vector. |
|
|
GetType | Gets the Type of the current
instance. (Inherited from Object) |
|
|
Inverse | Returns the inverse of this scale vector. |
|
|
IsEqualTo(Scale2d) | Checks whether the specified scale vector equals this scale vector. |
|
|
IsEqualTo(Scale2d, Tolerance) | |
|
|
IsProportional | Checks whether this scale vector scales uniformly. |
|
|
IsProportional(Tolerance) | |
|
|
MultiplyBy | |
|
|
PostMultiplyBy | Sets this scale vector to the product (this scale vector) * (rightSide), and returns the resulting vector. |
|
|
PreMultiplyBy | Sets this scale vector to the product (rightSide) * (this scale vector), and returns the resulting vector. |
|
|
RemoveScale | Returns the scale vector corresponding to the length of the column vectors of the transformation matrix, and sets the scale factor of the matrix to 1. |
|
|
ToArray | Returns an array of two values that represent the scale factors for x-and y-axes. |
|
|
ToString | Returns a string representation of this object. (Overrides ValueTypeToString) |
|
|
ToString(IFormatProvider) | Returns a string representation of this object. |
