ImageGear for .NET使用教程
ImageGear for .NET正式版
在本教程中，您将为控制台应用程序配置C＃或VB.NET项目，并使用ImageGear .NET功能。 您还将学习如何加载图像，然后调整大小并将其转换为新格式。
以下教程专门针对64位安装。 对于32位安装：
- 您的项目应该已经设置为可编译为以Debug和x86为目标，并且您应该具有以下目录：$ YOURLOCALPROJ bin x86 Debug 。
- 在整个说明中，将x64替换为x86。
- 在$ INSTALLDIR ImageGear .NET v24 Bin 中可以找到32位ImageGear二进制文件。
使用所需版本的Visual Studio（2010或更高版本）：
1、使用C＃或VB.NET创建一个新的“控制台应用程序”项目，并将该项目命名为IG_Tutorial_Console。
2、如果使用配置管理器安装了ImageGear .NET 64位，则为x64创建一个新的项目平台（如果尚未安装）。确保将项目设置为针对Debug和x64进行编译。确保您现在拥有$ YOURLOCALPROJ bin x64 Debug ，如果不存在，请创建它。
3、通过以下方式之一将引用和所需资源添加到项目中：
推荐：使用我们的NuGet软件包。对于此项目，您需要以下软件包：Accusoft.ImageGear.Core.nupkg
手动：
将$ INSTALLDIR ImageGear .NET v24 64位 Bin 中的所有文件（和文件夹）复制到项目中的本地输出bin目录（即$ YOURLOCALPROJ bin x64 Debug ）。
将以下引用从$ YOURLOCALPROJ bin x64 Debug 添加到您的项目：
- ImageGear24.Core.dll
- ImageGear24.Evaluation.dll
- ImageGear24.Formats.Common.dll
您的输出目标目录应设置为$ YOURLOCALPROJ bin x64 Debug
4、至此，您的项目已准备好编写一些代码。以下代码可用于加载图像，将其调整为150 x 150尺寸，并将其转换为用户指定的另一种格式。在下一步中，我们将更详细地介绍此示例代码的某些区域。
