Параметры

inkTransform
Тип: System.Drawing.Drawing2D.Matrix
The System.Drawing.Drawing2D.Matrix transform to use on the Stroke object.

Заметки

The transformation applies to the points, but not the pen width. To set a value that includes the pen width in the transformation, use the Transform(Matrix, Boolean) overload of this method.

The linear transform can represent scaling, rotation, translation, and combinations of transformations.

Примеры

This C# example rotates a Stroke object, theStroke, by 180 degrees around the center of the Stroke object's bounding box.

using System.Drawing.Drawing2D;
//...
Matrix inkTransform = new Matrix();
Rectangle inkBounds = theStroke.GetBoundingBox();
PointF center = new PointF(0.5f * (inkBounds.Left + inkBounds.Right),
                           0.5f * (inkBounds.Top + inkBounds.Bottom));
// Translate to center of bounding box
inkTransform.Translate(center.X, center.Y);
// Rotate by 180 degrees
inkTransform.Rotate(180f);
// Translate back
inkTransform.Translate(-center.X, -center.Y);
// Transform stroke
theStroke.Transform(inkTransform);

This Microsoft Visual Basic .NET example rotates a Stroke object, theStroke, by 180 degrees around the center of the Stroke object's bounding box.

'Translate to center of bounding box
inkTransform.Translate(center.X, center.Y)
'Rotate by 180 degrees
inkTransform.Rotate(180.0F)
'Translate back
