处理Adobe Illustrator格式

将AI文件导出为PSD

使用Aspose.PSD for .NET，开发人员可以将Adobe Illustrator文件转换为PSD格式。本主题解释了加载现有AI文件并使用PsdOptions类将其转换为PSD的方法。

将AI文件转换为PSD的步骤如下：

• 创建AiImage实例，并使用Image类的Load方法加载图像
• 创建PsdOptions类的实例
• 使用目标路径和PsdOptions的实例调用AiImage.Save方法

下面提供的示例代码演示了如何将AI导出为PSD。

// For complete examples and data files, please go to https://github.com/aspose-psd/Aspose.PSD-for-.NET

{
    @"34992OStroke",
    @"rect2_color",
};

for (int i = 0; i < sourcesFiles.Length; i++)
{
    string name = sourcesFiles[i];
    string sourceFileName = dataDir + name + ".ai";
    string outFileName = dataDir + name + ".psd";

    using (AiImage image = (AiImage)Image.Load(sourceFileName))
    {

        ImageOptionsBase options = new PsdOptions();
        image.Save(outFileName, options);

    }
}

将AI文件导出为JPEG

使用Aspose.PSD for .NET，开发人员可以将Adobe Illustrator文件转换为JPEG格式。本主题解释了加载现有AI文件并使用JpegOptions类将其转换为JPEG的方法。

将AI文件转换为JPEG的步骤如下：

• 创建AiImage实例，并使用Image类的Load方法加载图像
• 创建JpegOptions类的实例
• 设置图像的质量
• 使用目标路径和JpegOptions的实例调用AiImage.Save方法

下面提供的示例代码演示了如何将AI导出为JPEG。

// For complete examples and data files, please go to https://github.com/aspose-psd/Aspose.PSD-for-.NET

{
    @"34992OStroke",
    @"rect2_color",
};

for (int i = 0; i < sourcesFiles.Length; i++)
{
    string name = sourcesFiles[i];
    string sourceFileName = dataDir + name + ".ai";
    string outFileName = dataDir + name + ".jpg";

    using (AiImage image = (AiImage)Image.Load(sourceFileName))
    {

        ImageOptionsBase options = new JpegOptions() { Quality = 85 };
        image.Save(outFileName, options);

    }
}

将AI文件导出为GIF

Aspose.PSD for .NET提供了AiImage类来加载Adobe Illustrator文件，同样可以用于将AI文件导出为GIF格式。该示例演示了如何使用Aspose.PSD for .NET API来将AI文件导出为GIF图像。

// For complete examples and data files, please go to https://github.com/aspose-psd/Aspose.PSD-for-.NET

string[] sourcesFiles = new string[]
{
    @"34992OStroke",
    @"rect2_color",
};

for (int i = 0; i < sourcesFiles.Length; i++)
{
    string name = sourcesFiles[i];
    string sourceFileName = dataDir + name + ".ai";
    string outFileName = dataDir + name + ".gif";

    using (AiImage image = (AiImage)Image.Load(sourceFileName))
    {

        ImageOptionsBase options = new GifOptions() { DoPaletteCorrection = false };
        image.Save(outFileName, options);

    }
}

将AI文件导出为PNG

使用Aspose.PSD for .NET，开发人员可以将Adobe Illustrator文件转换为PNG格式。本主题解释了加载现有AI文件并使用PngOptions类将其转换为PNG的方法。

将AI文件转换为PNG的步骤如下：

• 创建AiImage实例，并使用Image类的Load方法加载图像
• 创建PngOptions类的实例
• 设置颜色类型
• 使用目标路径和PngOptions的实例调用AiImage.Save方法

下面提供的示例代码演示了如何将AI导出为PNG。

// For complete examples and data files, please go to https://github.com/aspose-psd/Aspose.PSD-for-.NET

string[] sourcesFiles = new string[]
{
    @"34992OStroke",
    @"rect2_color",
};

for (int i = 0; i < sourcesFiles.Length; i++)
{
    string name = sourcesFiles[i];
    string sourceFileName = dataDir + name + ".ai";
    string outFileName = dataDir + name + ".png";

    using (AiImage image = (AiImage)Image.Load(sourceFileName))
    {

        ImageOptionsBase options = new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha };
        image.Save(outFileName, options);

    }
}

将AI文件导出为TIFF

Aspose.PSD for .NET提供了AiImage类来加载Adobe Illustrator文件，同样可以用于将AI文件导出为TIFF格式。该示例演示了如何使用Aspose.PSD for .NET API来将AI文件导出为TIFF图像。

// For complete examples and data files, please go to https://github.com/aspose-psd/Aspose.PSD-for-.NET

string[] sourcesFiles = new string[]
{
    @"34992OStroke",
    @"rect2_color",
};

for (int i = 0; i < sourcesFiles.Length; i++)
{
    string name = sourcesFiles[i];
    string sourceFileName = dataDir + name + ".ai";
    string outFileName = dataDir + name + ".tif";

    using (AiImage image = (AiImage)Image.Load(sourceFileName))
    {

        ImageOptionsBase options = new TiffOptions(TiffExpectedFormat.TiffDeflateRgba);
        image.Save(outFileName, options);

    }
}
