Periksa batas bentuk dalam koleksi Shapes

Pendahuluan

Dokumen ini memberikan panduan rinci tentang penggunaan fitur pemeriksaan batas dalam koleksi Shapes. Fitur ini memastikan bahwa elemen sesuai dengan wadah induknya dan dapat dikonfigurasi untuk memicu pengecualian jika komponen tidak sesuai.

Prasyarat

Anda akan memerlukan hal-hal berikut:

• Visual Studio 2019 atau lebih baru
• Aspose.PDF for .NET 25.3 atau lebih baru
• Sebuah file PDF contoh yang berisi beberapa halaman

Anda dapat mengunduh pustaka Aspose.PDF for .NET dari situs web resmi atau menginstalnya menggunakan NuGet Package Manager di Visual Studio.

.NET Core 3.1

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);
    }
}
