asp.net教程 给图片加文字水印
文章分类:.net编程 关键字: asp.net 给图片加文字水印
using system.drawing;
using system.io;
using system.drawing.imaging;
private void addtexttoimg(string filename,string text)
{
if(!file.exists(mappath(filename)))
{
throw new filenotfoundexception("the file don"t exist!");
}if( text == string.empty )
{
return;
}
//还需要判断文件类型是否为图像类型，这里就不赘述了
system.drawing.image image = system.drawing.image.fromfile(mappath(filename));
bitmap bitmap = new bitmap(image,image.width,image.height);
graphics g = graphics.fromimage(bitmap);
float fontsize = 12.0f; //字体大小
float textwidth = text.length*fontsize; //文本的长度
//下面定义一个矩形区域，以后在这个矩形里画上白底黑字
float rectx = 0;
float recty = 0;
float rectwidth = text.length*(fontsize 8);
float rectheight = fontsize 8;
//声明矩形域
rectanglef textarea = new rectanglef(rectx,recty,rectwidth,rectheight);
font font = new font("宋体",fontsize); //定义字体
brush whitebrush = new solidbrush(color.white); //白笔刷，画文字用
brush blackbrush = new solidbrush(color.black); //黑笔刷，画背景用
g.fillrectangle(blackbrush,rectx,recty,rectwidth,rectheight);
g.drawstring(text,font,whitebrush,textarea);
memorystream ms = new memorystream( );
//保存为jpg类型
bitmap.save(ms,imageformat.jpeg);
//输出处理后的图像，这里为了演示方便，我将图片显示在页面中了
response.clear();
response.contenttype = "image/jpeg";
response.binarywrite( ms.toarray() );
g.dispose();
bitmap.dispose();
image.dispose();
}
调用时很简单，
addtexttoimg("me.jpg","family.man");
