Clipart Library Brightness and Contrast. ワールド変換により画像を平行移動、拡大、縮小、回転して表示する: .NET Tips: C#, VB.NET. 「画像を拡大、縮小（スケーリング）して描画する」、「画像を傾けて表示する」にて画像を拡大、縮小、回転して表示する方法を紹介しましたが、ここでは「ワールド変換行列」を使う方法を紹介します。 ワールド変換行列はMatrixオブジェクトで表わされ、Matrixオブジェクトには2x2の線形変換のための行列と、1x2の平行移動のための行列が組み合わさった、3x3のアフィン行列が格納されています（詳しくはMSDNの「変換の行列表現」をご覧ください）。 あるGraphicsオブジェクトで描画されるすべての画像や図形に適用する変換（グローバル変換）のためのMatrixオブジェクトは、GraphicsオブジェクトのTransformプロパティで取得、設定が出来ます。
なにやら難しいことになってきましたが、平行移動、スケーリング（拡大、縮小）、回転に関しては簡単に実現する方法が用意されていますので、ここではそれらを使うことにします。 あるGraphicsオブジェクトのワールド変換に平行移動を適用するにはGraphics.TranslateTransformメソッドを、スケーリングを適用するにはGraphics.ScaleTransformメソッドを、回転を適用するにはGraphics.RotateTransformメソッドをそれぞれ使用します。 次にこれらの変換を利用して画像を描画する例を示します。 <span class="notice">JavaScriptを有効にしてください</span> 画像を拡大、縮小、回転のためにこのようなワールド変換を行うとき、画像だけが拡大、縮小、回転するわけではないことに注意してください。 複合変換 上記の例ではそれぞれの変換を独立して行うため、ワールド変換を指定する前にResetTransformメソッドにより、ワールド変換行列を単位行列にリセットしています。 次にこのことを確認するため、リセットせずに平行移動後回転のワールド変換を設定してみます。 この結果を見ると、回転後に平行移動していることが分かります。 平行移動後に回転されているのがお分かりいただけるでしょう。 これらの結果を見れば一目瞭然ですが、変換操作を後ろにするか前にするかという順番は場合によってはとても重要になります。 注意：この記事では、基本的な事柄の説明が省略されているかもしれません。 GDI+ 和SetWindowRgn 创建不规则窗体_程序人生——用代码记录你的思想. Matrix Transformation of Images in C#, using .NET GDI+ Download demo project - 30.7 Kb Introduction 2D image transformation in .NET has been very much simplified by the Matrix class in the System.Drawing.Drawing2D namespace.
In this article, I would like to share with the reader on the use of Matrix class for 2D image transformation. Background The Matrix class takes 6 elements arranged in 3 rows by 2 cols. This is a simplification of: The last column is always: Thus a translation transformation of movement of 3 in x-axis and 2 in the y-axis would be represented as: but internally is represented as An important thing to note is that the transformation matrix is post multiplied to the image vectors. When the transformation matrix is operated on the image matrix, the transformation matrix is multiplied on the right of the image matrix. The last column of the resulting matrix is ignored. A composite transformation is made up of the product of two or more matrices.
Internally represented as Matrix Transformation To create a Matrix object: Flipping. Image Transition in VB.NET Windows Forms. Download source code - 247 KB Introduction This article demonstrates how to implement a simple transition on images in VB.NET. Transitions are one of the most useful features used in slide shows, business presentations, videos, screensavers, and with transitions, coders can build simple and easy visual effects on their web pages/Windows Forms/videos with simple and very minimal code.
Background You may find a lot of articles that demonstrate how to implement image transitions using Silverlight or Dynamic HTML, but it's rare to find articles that talk about image transitions either in C# or VB.NET Windows Forms ...... apparently, image transitions are very good business. In this article, I'll try to explain some of the most popular image transition methods and how they are done. Transitions and Visual Effects The list below shows the most popular image visual effects/transitions. Transitions Timing Declare timer: Private m_timer As New System.Timers.Timer() Draw something in the Paint event: レジ作者Q&A. Image Rotation in .NET.
Introduction A few days ago Tweety asked me how you would go about rotating an Image object. The reply seemed simple enough, use the Transform property of your Graphics object with a Matrix object having the appropriate Rotate method called on it. But I forgot about one aspect regarding the transforms, while it is easy to rotate the Image, you have to jump through hoops to get it to rotate correctly and still remain in somewhat the same location. Since I was disgusted from looking at the same non-working code for the past two weeks this was a welcome vacation.
My first attempt I wanted to take what seemed the obvious way to do this, so I started messing around with the Rotate/RotateAt methods and trying to figure out what the equation to create the proper translation should be. My second attempt or Ah ha! Given an angle of rotation, theta, and knowing the width and height of the original bitmap I can figure out the size of the triangles of 'empty space'. Solving for the unknown you get:
