将一个数组复制到另一个数组.

问题描述

你好

我想在btb图像上实现缩放.我有一个像素数组，我的目标是获取第一个像素，将其存储在另一个4乘4像素的数组中，然后需要对其余数组进行此操作.

所以我要做的是:

Hello

I want to implement zoom on an btb image . I have my array with pixels , my goal is to take the first pixel , store it in another array in a block of 4 by 4 pixels and then I need to do this with the rest of the array.

So what I want to do is this:

pixelArray[1,1] =     {{2,3}       
                       {4,5}}

这:

{{2,2,3,3}
 {2,2,3,3}
 {4,4,5,5}
 {4,4,5,5} }

C#中有功能吗?
我应该如何解决这个问题?
谢谢！

Is there a function in C# ?
How should I solve this problem??
Thank you!

推荐答案

using System.Drawing.Drawing2D;

构造一个新矩阵:

Construct a new matrix:

Matrix m = new Matrix();

将X按1/2缩放，将y按1 1/2缩放:

Scale the X by 1/2 and the y by 1 1/2:

m.Scale(0.5F, 1.5F);

应用转换:

Apply the transformation:

e.Graphics.Transform = m;
