从头开始创建图形，并返回他们打印页面事件 [英] Creating graphics from scratch and returning them to print a page event

问题描述

我的工作在C＃.NET 3.5。我有一个类食谱包含图像和一些字符串。我想打印出这些食谱，百分之四页。我想在课堂上返回的东西吸引到我的打印文档写了一个getprintobject的功能，但我难倒...

I'm working in C# .NET 3.5. I have a class of recipes that contains an image and some strings. I want to print out these recipes, four per page. I want to write a "getprintobject" function in the class to return something to draw onto my print document, but I'm stumped...

我希望我可以创建并返回一个图形对象，但我没有看到一个e.graphics.drawgraphics（）。我也想过创建位图或图像并返回了，但我不知道如何建立一个从无到有，得到一个新的图形对象进行修改。

I wish I could just create and return a graphics object, but I don't see a "e.graphics.drawgraphics()". I have also thought about creating a bitmap or image and returning that, but I'm not sure how to create one from scratch and get a new graphics object to modify it.

推荐答案

创建映像，并使用该图像为基础的图形对象。例如，

Create an Image, and use that image as a base for your Graphics object. e.g.

Bitmap img = new Bitmap(50, 50);
Graphics g = Graphics.FromImage(img);

绘制你的图形对象，将借鉴图像 - 然后你就可以返回

Drawing on your graphics object, will draw on your image -- which you can then return.
