LayoutTransformer

LayoutTransformer

public LayoutTransformer()

layoutTransformer = LayoutTransformer()

Initializes a new instance of the LayoutTransformer class.

Child

private FrameworkElement Child { get; }

value = layoutTransformer.Child

Gets the child element being transformed.

LayoutTransform

public Transform LayoutTransform { get; set; }

value = layoutTransformer.LayoutTransform
layoutTransformer.LayoutTransform = value

Gets or sets the layout transform to apply on the LayoutTransformer control content.

ApplyLayoutTransform

public void ApplyLayoutTransform()

layoutTransformer.ApplyLayoutTransform()

Applies the layout transform on the LayoutTransformer control content.

ArrangeOverride

protected override Size ArrangeOverride(Size finalSize)

result = layoutTransformer.ArrangeOverride(finalSize)

Provides the behavior for the "Arrange" pass of layout.

finalSize

The final area within the parent that this element should use to arrange itself and its children.

Returns: The actual size used.

ComputeLargestTransformedSize

private Size ComputeLargestTransformedSize(Size arrangeBounds)

result = layoutTransformer.ComputeLargestTransformedSize(arrangeBounds)

Compute the largest usable size (greatest area) after applying the transformation to the specified bounds.

arrangeBounds

Arrange bounds.

Returns: Largest Size possible.

DiagnosticWriteLine

private static void DiagnosticWriteLine(string message)

LayoutTransformer.DiagnosticWriteLine(message)

Outputs diagnostic info if DIAGNOSTICWRITELINE is defined.

message

Diagnostic message.

GetTransformMatrix

private Matrix GetTransformMatrix(Transform transform)

result = layoutTransformer.GetTransformMatrix(transform)

Walks the Transform(Group) and returns the corresponding Matrix.

transform

Transform(Group) to walk.

Returns: Computed Matrix.

IsSizeSmaller

private static bool IsSizeSmaller(Size a, Size b)

result = LayoutTransformer.IsSizeSmaller(a, b)

Returns true if Size a is smaller than Size b in either dimension.

a

Second Size.

b

First Size.

Returns: True if Size a is smaller than Size b in either dimension.

LayoutTransformChanged

private static void LayoutTransformChanged(DependencyObject o, DependencyPropertyChangedEventArgs e)

LayoutTransformer.LayoutTransformChanged(o, e)

Handles changes to the Transform DependencyProperty.

o

Source of the change.

e

Event args.

MatrixHasInverse

private static bool MatrixHasInverse(Matrix matrix)

result = LayoutTransformer.MatrixHasInverse(matrix)

Implements WPF's Matrix.HasInverse on Silverlight.

matrix

Matrix to check for inverse.

Returns: True if the Matrix has an inverse.

MatrixMultiply

private static Matrix MatrixMultiply(Matrix matrix1, Matrix matrix2)

result = LayoutTransformer.MatrixMultiply(matrix1, matrix2)

Implements WPF's Matrix.Multiply on Silverlight.

matrix1

First matrix.

matrix2

Second matrix.

Returns: Multiplication result.

MeasureOverride

protected override Size MeasureOverride(Size availableSize)

result = layoutTransformer.MeasureOverride(availableSize)

Provides the behavior for the "Measure" pass of layout.

availableSize

The available size that this element can give to child elements.

Returns: The size that this element determines it needs during layout, based on its calculations of child element sizes.

OnApplyTemplate

public override void OnApplyTemplate()

layoutTransformer.OnApplyTemplate()

Builds the visual tree for the LayoutTransformer control when a new template is applied.

ProcessTransform

private void ProcessTransform(Transform transform)

layoutTransformer.ProcessTransform(transform)

Processes the Transform to determine the corresponding Matrix.

transform

Transform to process.

RectTransform

private static Rect RectTransform(Rect rect, Matrix matrix)

result = LayoutTransformer.RectTransform(rect, matrix)

Implements WPF's Rect.Transform on Silverlight.

rect

Rect to transform.

matrix

Matrix to transform with.

Returns: Bounding box of transformed Rect.

RoundMatrix

private static Matrix RoundMatrix(Matrix matrix, int decimals)

result = LayoutTransformer.RoundMatrix(matrix, decimals)

Rounds the non-offset elements of a Matrix to avoid issues due to floating point imprecision.

matrix

Matrix to round.

decimals

Number of decimal places to round to.

Returns: Rounded Matrix.

AcceptableDelta

private const double AcceptableDelta

value = LayoutTransformer.AcceptableDelta

Acceptable difference between two doubles.

DecimalsAfterRound
