在本教程中，您將為控制臺應(yīng)用程序配置C＃或VB.NET項目，并使用ImageGear .NET功能。 您還將學(xué)習(xí)如何加載圖像，然后調(diào)整大小并將其轉(zhuǎn)換為新格式。本教程內(nèi)容較多，分為上下兩篇內(nèi)容，本文為后半部分內(nèi)容，緊接上文！

5、如果使用的是部署（運行時）許可，請?zhí)砑釉S可初始化代碼。 如果您正在使用評估或開發(fā)（工具包）許可證，則沒有必要。 如果您正在評估產(chǎn)品，請?zhí)砑覫mGearEvaluationManager.Initialize（）調(diào)用。

C#

// Initialize license for a Deployment(Runtime) license.
//***The SetSolutionName, SetSolutionKey and possibly the SetOEMLicenseKey
//methods must be called to distribute the runtime.***
//ImGearLicense.SetSolutionName("YourSolutionName");
//ImGearLicense.SetSolutionKey(12345, 12345, 12345, 12345);
//Manually Reported Runtime licenses also require the following method
//call to SetOEMLicenseKey.
//ImGearLicense.SetOEMLicenseKey("2.0.AStringForOEMLicensing...");

// Initialize evaluation license.
ImGearEvaluationManager.Initialize();

// Initialize common formats.
ImGearCommonFormats.Initialize();

VB.NET

' Initialize license for a Deployment(Runtime) license.
'***The SetSolutionName, SetSolutionKey and possibly the SetOEMLicenseKey
'methods must be called to distribute the runtime.***
'ImGearLicense.SetSolutionName("YourSolutionName");
'ImGearLicense.SetSolutionKey(12345, 12345, 12345, 12345);
'Manually Reported Runtime licenses also require the following method
'call to SetOEMLicenseKey.
'ImGearLicense.SetOEMLicenseKey("2.0.AStringForOEMLicensing...");

'Initialize evaluation license.
ImGearEvaluationManager.Initialize()

'Initialize common formats.
ImGearCommonFormats.Initialize()

6、我們使用以下方法加載圖像：

C#

// Load the image into the page.
ImGearPage imGearPage = ImGearFileFormats.LoadPage(stream, 0);

VB.NET

' Load the image into the page.
Dim imGearPage As ImGearPage = ImGearFileFormats.LoadPage(stream, 0)

7、我們通過定義寬度，高度和插值方法來調(diào)整圖像的大小，如下所示：

C#

// Resize the image to the width and height specified.
// ImGearInterpolations.BILINEAR is the value indicating the type of interpolation employed.
// It may be changed for other values, e.g. ImGearInterpolations.BICUBIC, ImGearInterpolations.NEAREST_NEIGHBOR.
ImGearProcessing.Resize(imGearPage, 150, 150, ImGearInterpolationOptions.GetDefault(ImGearInterpolations.BILINEAR));

VB.NET

' Resize the image to the width and height specified.
' ImGearInterpolations.BILINEAR is the value indicating the type of interpolation employed.
' It may be changed for other values, e.g. ImGearInterpolations.BICUBIC, ImGearInterpolations.NEAREST_NEIGHBOR.
ImGearProcessing.Resize(imGearPage, 150, 150, ImGearInterpolationOptions.GetDefault(ImGearInterpolations.BILINEAR))

8、最后，我們根據(jù)指定的saveFormat保存圖像：

C#

// Save the image to the format selected.
ImGearFileFormats.SavePage(imGearPage, imGearConverted, 1, ImGearSavingModes.OVERWRITE, savingFormat, new ImGearSaveOptions());

VB.NET

' Save the image to the format selected.
ImGearFileFormats.SavePage(imGearPage, imGearConverted, 1, ImGearSavingModes.OVERWRITE, savingFormat, New ImGearSaveOptions())
