本文介绍如何使用Spire.Presentation for .NET设置形状中文字的对齐方式。

using Spire.Presentation.Drawing;

namespace TextAlignment
{
    class Program
    {
        static void Main(string[] args)
        {
            //创建Presentation对象
            Presentation presentation = new Presentation();
            presentation.SlideSize.Type = SlideSizeType.Screen16x9;  

            //添加形状
            IAutoShape textShape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 50, 400, 200));
            textShape.ShapeStyle.LineColor.Color = Color.DarkGray;
            textShape.Fill.FillType = FillFormatType.None;

            //删除默认段落
            textShape.TextFrame.Paragraphs.Clear();

            //添加段落和文字
            textShape.TextFrame.Paragraphs.Append(new TextParagraph());
            textShape.TextFrame.Paragraphs[0].TextRanges.Append(new TextRange("文字对齐方式"));
            textShape.TextFrame.Paragraphs[0].TextRanges[0].FontHeight = 20f;
            textShape.TextFrame.Paragraphs[0].TextRanges[0].LatinFont = new TextFont("黑体");
            textShape.TextFrame.Paragraphs[0].TextRanges[0].Fill.FillType = FillFormatType.Solid;
            textShape.TextFrame.Paragraphs[0].TextRanges[0].Fill.SolidColor.Color = Color.Black;

            //设置文字水平靠右
            textShape.TextFrame.Paragraphs[0].Alignment = TextAlignmentType.Right;

            //设置文字垂直靠下
            textShape.TextFrame.AnchoringType = TextAnchorType.Bottom;

            //保存文档
            presentation.SaveToFile("AlignText.pptx", FileFormat.Pptx2013);
        }
    }
