检查形状集合中的形状边界

介绍

本文档提供了关于如何使用形状集合中的边界检查功能的详细指南。此功能确保元素适合其父容器，并可以配置为在组件不适合时抛出异常。

先决条件

您需要以下内容：

• Visual Studio 2019 或更高版本
• Aspose.PDF for .NET 25.3 或更高版本
• 一个包含一些页面的示例 PDF 文件

您可以从官方网站下载 Aspose.PDF for .NET 库，或通过 Visual Studio 中的 NuGet 包管理器安装它。

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void CheckShapeBounds()
{
    // Create PDF document
    using (var document = new Aspose.Pdf.Document())
    {
        // Add page
        var page = document.Pages.Add();

        // Create a Graph object with specified dimensions
        var graph = new Aspose.Pdf.Drawing.Graph(100d, 100d)
        {
            Top = 10,
            Left = 15,
            Border = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.Box, 1F, Aspose.Pdf.Color.Black)
        };
        page.Paragraphs.Add(graph);

        // Create a Shape object (for example, Rectangle) with specified dimensions
        var rect = new Aspose.Pdf.Drawing.Rectangle(-1, 0, 50, 50)
        {
            GraphInfo =
            {
                FillColor = Aspose.Pdf.Color.Tomato
            }
        };

        // Set the BoundsCheckMode to ThrowExceptionIfDoesNotFit
        graph.Shapes.UpdateBoundsCheckMode(Aspose.Pdf.BoundsCheckMode.ThrowExceptionIfDoesNotFit);

        // Add the rectangle to the graph
        graph.Shapes.Add(rect);
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void CheckShapeBounds()
{
    // Create PDF document
    using var document = new Aspose.Pdf.Document();

    // Add page
    var page = document.Pages.Add();

    // Create a Graph object with specified dimensions
    var graph = new Aspose.Pdf.Drawing.Graph(100d, 100d)
    {
        Top = 10,
        Left = 15,
        Border = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.Box, 1F, Aspose.Pdf.Color.Black)
    };
    page.Paragraphs.Add(graph);

    // Create a Aspose.Pdf.Drawing.Shape object (for example, Aspose.Pdf.Drawing.Rectangle) with specified dimensions
    var rect = new Aspose.Pdf.Drawing.Rectangle(-1, 0, 50, 50)
    {
        GraphInfo =
        {
            FillColor = Aspose.Pdf.Color.Tomato
        }
    };

    // Set the BoundsCheckMode to ThrowExceptionIfDoesNotFit
    graph.Shapes.UpdateBoundsCheckMode(Aspose.Pdf.BoundsCheckMode.ThrowExceptionIfDoesNotFit);

    // Add the rectangle to the graph
    graph.Shapes.Add(rect);
