在C＃中重复图像 [英] Repeat image in C#

问题描述

我有一定的图案的图像。我如何使用GDI重复它在另一个形象？
是否有任何方法来做到这一点在GDI？

I have an image with a certain pattern. How do I repeat it in another image using GDI? Is there any method to do it in GDI?

推荐答案

在C＃中，你可以创建一个的TextureBrush那会瓷砖无论你使用它，然后用它填充区域图像。像这样的东西（即填满整个图像的例子）...

In C#, you can create a TextureBrush that'll tile your image wherever you use it, and then fill an area with it. Something like this (an example that fills the whole image)...

// Use `using` blocks for GDI objects you create, so they'll be released
// quickly when you're done with them.
using (TextureBrush brush = new TextureBrush(yourImage, WrapMode.Tile))
using (Graphics g = Graphics.FromImage(destImage))
{
    // Do your painting in here
    g.FillRectangle(brush, 0, 0, destImage.Width, destImage.Height);
}

请注意，如果你想在图像是如何平铺一些控制，你' 。重新将需要学习一些关于转换

Note, if you want some control over how the image is tiled, you're going to need to learn a bit about transforms.

我几乎忘了（其实我做了一个有点忘了）：你需要导入 System.Drawing中（为图形和的TextureBrush ）和 System.Drawing.Drawing2D （为 WrapMode ），以便上面的代码工作原样。

I almost forgot (actually I did forget for a bit): You'll need to import System.Drawing (for Graphics and TextureBrush) and System.Drawing.Drawing2D (for WrapMode) in order for the code above to work as is.
