C# 绘制Word形状88bf必发娱乐——基本形状、组合形状

通过对控件Spire.PDF的测试,我们可以创建PDF文件并向文档中绘制文本、图片、表格、图形等内容,其中,对于绘制文本这一部分,Spire.PDF提供了三种字体类型来绘制文本,即:

一、序言

在Office
Word中,支持在Word文档中插入类型非常丰富的形状,包括线条、矩形、基本形状(诸如圆形、多边形、星形、括号、笑脸等等图形)、箭头形状、公式形状、流程图、旗帜图形、标注图形等等,我们在编程过程中,想要在Word中绘制不同类型的图形,可以通过类库来操作。控件Spire.Doc
for .NET 6.0及以上版本开始支持Office
Word中的所有图形,可以通过代码操作某个单一的形状,也可以通过将单一形状进行组合来获得想要的图形或形状效果,当然,也支持自己自定义图形,通过编程绘制也是可以的。下面将介绍向Word绘制形状和组合形状的方法,方法中的代码供参考。

PS:

  • Spire.Doc for
    .NET
    获取地址
  • 安装后,dll文件可在安装路径下的Bin文件夹中获取

  • Standard fonts
  • TrueType fonts
  • Chinese, Japanese and Korean (CJK) fonts

二、代码示例

从以上类中我们可以发现,是可以支持中、日、韩、英等字体类的,这为我们在操作PDF文件上提供了更多可能。在这篇文章中,“利用private
font改变PDF文件的字体
”中讲述了如何应用字体,在接下来的文章中,将介绍如何运用Spire.PDF提供的字体类来绘制不同风格类型的文本。

(一)绘制单一形状

步骤1:添加如下using指定

using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System.Drawing;

 

步骤2:创建示例,添加section、paragraph

//创建一个Document实例
Document doc = new Document();
//添加一个section paragraph
 Section sec = doc.AddSection();
 Paragraph para1 = sec.AddParagraph();

 

步骤3:在文档指定位置插入形状,并设置形状类型、大小、填充颜色、线条样式等

(这里简单列举几个形状的添加方法,方法比较简单,不做赘述,效果图中列举了部分形状样式,需要其他样式的形状可自行设置添加)

           //插入一个矩形
            ShapeObject shape1 = para1.AppendShape(50, 50, ShapeType.Rectangle);
            shape1.FillColor = Color.Blue;
            shape1.StrokeColor = Color.LightSkyBlue;
            shape1.HorizontalPosition = 20;
            shape1.VerticalPosition = 20;

            //插入一个圆形
            ShapeObject shape2 = para1.AppendShape(50, 50, ShapeType.Ellipse);
            shape2.FillColor = Color.Purple;
            shape2.StrokeColor = Color.LightPink;
            shape2.LineStyle = ShapeLineStyle.Single;
            shape2.StrokeWeight = 1;
            shape2.HorizontalPosition = 80;
            shape2.VerticalPosition = 20;

            //插入一个公式符号 +
            ShapeObject shape3 = para1.AppendShape(50, 50, ShapeType.Plus);
            shape3.FillColor = Color.DarkCyan;
            shape3.StrokeColor = Color.LightGreen;
            shape3.LineStyle = ShapeLineStyle.Single;
            shape3.StrokeWeight = 1;
            shape3.HorizontalPosition = 140;
            shape3.VerticalPosition = 20;

            //插入一颗星形
            ShapeObject shape4 = para1.AppendShape(50, 50, ShapeType.Star);
            shape4.FillColor = Color.Red;
            shape4.StrokeColor = Color.Gold;
            shape4.LineStyle = ShapeLineStyle.Single;
            shape4.HorizontalPosition = 200;
            shape4.VerticalPosition = 20;

 

步骤4:保存文档

//保存并打开文档
doc.SaveToFile("InsertShapes.docx", FileFormat.Docx2010);
System.Diagnostics.Process.Start("InsertShapes.docx");

(二)添加组合形状

步骤1:添加如下using指令

using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System.Drawing;

 

步骤2:创建文档,添加section、paragraph

Document doc = new Document();
Section sec = doc.AddSection();
Paragraph para1 = sec.AddParagraph();

 

步骤3:添加文字,并应用格式到文字

para1.AppendText("中日文化交流");
ParagraphStyle style1 = new ParagraphStyle(doc);
style1.Name = "titleStyle";
style1.CharacterFormat.Bold = true;
style1.CharacterFormat.FontName = "隶书";
style1.CharacterFormat.FontSize = 30f;
doc.Styles.Add(style1);
para1.ApplyStyle("titleStyle");
para1.Format.HorizontalAlignment = HorizontalAlignment.Center;

 

步骤4:实例化段落2,并创建一个形状组合,并设置大小

//实例化段落2
Paragraph para2 = sec.AddParagraph();
//创建一个形状组合并设置大小
ShapeGroup shapegr = para2.AppendShapeGroup(300, 300);

 

步骤5:绘制一个中国国旗,这里需要组合形状矩形和五角星形,并填充相应的颜色

 //添加一个矩形到形状组合
            shapegr.ChildObjects.Add(new ShapeObject(doc, ShapeType.Rectangle)
            {

                FillColor = Color.Red,
                StrokeColor = Color.Red,                
                StrokeWeight = 1,
            });

            //添加第一个五角星到形状组合
            shapegr.ChildObjects.Add(new ShapeObject(doc, ShapeType.Star)
            {
                Width = 100,
                Height = 100,
                VerticalPosition = 90,
                HorizontalPosition = 90,
                LineStyle = ShapeLineStyle.Single,
                FillColor = Color.Yellow,
                StrokeColor = Color.Yellow,
                StrokeWeight = 1,
            });
            //添加第二个五角星到形状组合
            shapegr.ChildObjects.Add(new ShapeObject(doc, ShapeType.Star)
            {
                Width = 50,
                Height = 50,
                VerticalPosition = 40,
                HorizontalPosition = 210,
                LineStyle = ShapeLineStyle.Single,
                FillColor = Color.Yellow,
                StrokeColor = Color.Yellow,
                StrokeWeight = 1,
            });
            //添加第三个五角星到形状组合
            shapegr.ChildObjects.Add(new ShapeObject(doc, ShapeType.Star)
            {
                Width = 50,
                Height = 50,
                VerticalPosition = 80,
                HorizontalPosition = 280,
                LineStyle = ShapeLineStyle.Single,
                FillColor = Color.Yellow,
                StrokeColor = Color.Yellow,
                StrokeWeight = 1,
            });
            //添加第四个五角星到形状组合
            shapegr.ChildObjects.Add(new ShapeObject(doc, ShapeType.Star)
            {
                Width = 50,
                Height = 50,
                VerticalPosition = 160,
                HorizontalPosition = 280,
                LineStyle = ShapeLineStyle.Single,
                FillColor = Color.Yellow,
                StrokeColor = Color.Yellow,
                StrokeWeight = 1,
            });
            //添加第五个五角星到形状组合
            shapegr.ChildObjects.Add(new ShapeObject(doc, ShapeType.Star)
            {
                Width = 50,
                Height = 50,

            });

 

步骤6:绘制一个日本国旗,需要组合形状矩形和圆形,并填充颜色

//绘制一个矩形并添加到形状组合
            shapegr.ChildObjects.Add(new ShapeObject(doc, ShapeType.Rectangle)
            {
                Width = 900,
                Height = 500,
                VerticalPosition = 700,
                HorizontalPosition = 600,
                LineStyle = ShapeLineStyle.Single,
                FillColor = Color.WhiteSmoke,
                StrokeColor = Color.WhiteSmoke,
                StrokeWeight = 1,
            });
            //绘制一个圆形并添加到形状组合
            shapegr.ChildObjects.Add(new ShapeObject(doc, ShapeType.Ellipse)
            {
                Width = 250,
                Height = 250,
                VerticalPosition = 800,
                HorizontalPosition = 900,
                LineStyle = ShapeLineStyle.Single,
                FillColor = Color.Red,
                StrokeColor = Color.Red,
                StrokeWeight = 1,
            });

 

步骤7:保存文档

//保存并打开文档
doc.SaveToFile("InsertShapegroups.docx", FileFormat.Docx2010);
System.Diagnostics.Process.Start("InsertShapegroups.docx");

【示例1】绘制倾斜样式的文本

 步骤1:创建实例

PdfDocument doc = new PdfDocument(); 
PdfPageBase page = doc.Pages.Add();    

步骤2:保存画布状态

PdfGraphicsState state = page.Canvas.Save();

步骤3:实例化字体,创建格式刷

PdfFont font = new PdfFont(PdfFontFamily.Helvetica, 18f);
PdfSolidBrush brush1 = new PdfSolidBrush(Color.DeepSkyBlue);
PdfSolidBrush brush2 = new PdfSolidBrush(Color.CadetBlue);
PdfSolidBrush brush3 = new PdfSolidBrush(Color.LightPink);

步骤4:指定文本在画布上的坐标,并指定文本的横向、纵向的拉伸度

page.Canvas.TranslateTransform(10, 100);
page.Canvas.ScaleTransform(1f, 0.6f);

步骤5:绘制文本

 //绘制倾斜样式的文本
 page.Canvas.SkewTransform(-10, 0);
 page.Canvas.DrawString("THERE IS NO ROYAL ROAD TO LEARNING. ", font, brush1, 0, 0);
 page.Canvas.SkewTransform(10, 10);
 page.Canvas.DrawString("Books, like friends, should be few and well chosen. ", font, brush2, 10, 50);

 //绘制缩放类型的文本
 page.Canvas.ScaleTransform(1f, -1f);
 page.Canvas.DrawString("Books, like friends, should be few and well chosen.", font, brush3, 10, -2 * 50);

步骤6:再次保存画布

page.Canvas.Restore(state);

步骤7:保存文件

doc.SaveToFile("DrawText.pdf");
System.Diagnostics.Process.Start("DrawText.pdf");

测试效果:

【示例2】绘制中心旋转图形

 步骤1:创建实例

PdfDocument doc = new PdfDocument();
PdfPageBase page = doc.Pages.Add(); 

步骤2:保存画布

 PdfGraphicsState state = page.Canvas.Save();

步骤3:实例化字体类,创建格式刷

PdfFont font = new PdfFont(PdfFontFamily.Helvetica, 10f);
PdfSolidBrush brush = new PdfSolidBrush(Color.BlueViolet);

步骤4:设定字符串布局格式,并指定文本在画布中的位置

PdfStringFormat centerAlignment = new PdfStringFormat(PdfTextAlignment.Left, PdfVerticalAlignment.Middle);
float x = 400;
float y = 600;
page.Canvas.TranslateTransform(x, y);

步骤5:绘制文本,应用格式

//指定文本绘制数量
for (int i = 0; i < 12; i++)
{
    //设置文本按顺时针方向旋转排列(文本偏移间隔30度)
    page.Canvas.RotateTransform(30);
    //绘制文本并应用格式                
    page.Canvas.DrawString("Every tide has its ebb.", font, brush, 10, 0, centerAlignment);
}

步骤6:再次保存画布

page.Canvas.Restore(state);

步骤7:保存文档

doc.SaveToFile("DrawText.pdf");
System.Diagnostics.Process.Start("DrawText.pdf");

测试结果:

(这里做了几个不同样式的demo,可以对比看下效果)
