我使用名爲「drawCanvas」的畫布來顯示畫布中包含的名爲「CanvasContainInkCanvas」的圖像和inkcanvas。我可以通過使用MatrixTransform縮小。如何在inkcanvas外部顯示圖像
//Get the image that's being manipulation.
Canvas element = (Canvas)e.Source;
//Ues the matrix of the transform to manipulation the element's appearance.
Matrix matrix = ((MatrixTransform)drawCanvas.RenderTransform).Matrix;
//Get the ManipulationDelta object.
ManipulationDelta deltaManipulation = e.DeltaManipulation;
//Find the old center, and apply any previous manipulations.
Point center = new Point(element.ActualWidth/2, element.ActualHeight/2);
//Apply new move manipulation (if it exists).
center = matrix.Transform(center);
//Apply new zoom manipulation (if it exists).
matrix.ScaleAt(deltaManipulation.Scale.X, deltaManipulation.Scale.Y, center.X, center.Y);
//Translation (pan)
matrix.Translate(e.DeltaManipulation.Translation.X, e.DeltaManipulation.Translation.Y);
//Set the final matrix.
((MatrixTransform)drawCanvas.RenderTransform).Matrix = matrix;
// set the matrix of canvas that contain inkcanvas
((MatrixTransform)CanvasContainInkCanvas.RenderTransform).Matrix = matrix;
如果我縮小,我可以看到畫布外的圖像。
我想複製圖像從畫布到inkcanvas使用選擇。 我的問題是,圖像無法顯示在inkcanvas之外。
如何顯示外inkcanvas圖像?
感謝
更新:我如何使用選擇外inkcanvas?
好吧,我現在可以顯示圖像,但我有新問題。如何使用inkcanvas外部的選擇? – 2011-01-13 09:01:23
