c#/vb.net 创建 powerpoint 文档-ag凯发旗舰厅

powerpoint文档（幻灯片）是一种常见的演示文档，在演讲，教学，产品演示等方面得到广泛的应用。本文将介绍如何通过编程的方式创建powerpoint文档。

创建简单的powerpoint文档

//新建一个powerpoint文档（默认包含一页空白幻灯片）
presentation ppt = new presentation();
//设置幻灯片大小和方向
ppt.slidesize.type = slidesizetype.screen16x9;
ppt.slidesize.orientation = slideorienation.landscape;
//为幻灯片设置背景图片
string imagefile = "background.jpg";
rectanglef rect = new rectanglef(0, 0, ppt.slidesize.size.width, ppt.slidesize.size.height);
ppt.slides[0].slidebackground.fill.filltype = fillformattype.picture;
iembedimage image = ppt.slides[0].shapes.appendembedimage(shapetype.rectangle, imagefile, rect);
ppt.slides[0].slidebackground.fill.picturefill.picture.embedimage = image as iimagedata;
//添加一个图形（shape)到第一张幻灯片
iautoshape textboxshape = ppt.slides[0].shapes.appendshape(shapetype.rectangle, new rectanglef(50, 70, 600, 100));
textboxshape.shapestyle.linecolor.color = color.transparent;
textboxshape.fill.filltype = spire.presentation.drawing.fillformattype.none;
//清除图形上的段落（默认有一个空白段落）
textboxshape.textframe.paragraphs.clear();
//在图形上添加段落及内容
textboxshape.textframe.paragraphs.append(new textparagraph());        
textboxshape.textframe.paragraphs[0].textranges.append(new textrange("spire.presentation for .net"));
textboxshape.textframe.paragraphs[0].spaceafter = 50f;
//添加第二段及内容
textboxshape.textframe.paragraphs.append(new textparagraph());
string text = "一款专业的 powerpoint 组件，使用该组件，开发者可以在 .net 平台上对 powerpoint 文档进行生成、读取、写入、修改、"
               "转换和打印等操作。 作为一个独立的控件，spire.presentation for .net 的运行无需要安装 microsoft powerpoint。";
textboxshape.textframe.paragraphs[1].textranges.append(new textrange(text));
//设置段落中文字的字体、大小、颜色及段落的对齐方式、段首缩进距离
foreach (textparagraph para in textboxshape.textframe.paragraphs)
{
    para.textranges[0].latinfont = new textfont("arial rounded mt bold");
    para.textranges[0].fontheight = 13f;
    para.textranges[0].fill.filltype = fillformattype.solid;
    para.textranges[0].fill.solidcolor.color = color.black;
    para.alignment = textalignmenttype.left;
    para.indent = 35;
}
//保存文档
ppt.savetofile("创建powerpoint.pptx", fileformat.pptx2013);

设置文档属性

//通过documentproperty设置文档属性
