我要评论本文实例讲述了c#实现图片加相框的方法。分享给大家供大家参考，具体如下：
//加边框
try
{
bitmap backbmp = new bitmap(@"" + path);
float w = (float)(backbmp.width * 0.2);
using (graphics g = graphics.fromimage(backbmp))
{
using (brush brush = new solidbrush(color.fromargb(0, 156, 255)))
{
using (pen pen = new pen(brush, w))
{
pen.dashstyle = dashstyle.custom;
g.drawrectangle(pen, new rectangle(0, 0, math.abs(backbmp.width), math.abs(backbmp.height)));
g.dispose();
pic.backgroundimage = backbmp;
}
}
}
}
catch (exception)
{
}
//加椭圆
try
{
bitmap backbmp = new bitmap(@"" + path);
float w = (float)(backbmp.width * 0.2);
using (graphics g = graphics.fromimage(backbmp))
{
using (brush brush = new solidbrush(color.fromargb(0, 156, 255)))
{
using (pen pen = new pen(brush, w))
{
pen.dashstyle = dashstyle.custom;
g.drawellipse(pen, new rectangle(0, 0, math.abs(backbmp.width), math.abs(backbmp.height)));
g.dispose();
pic.backgroundimage = backbmp;
}
}
}
}
catch (exception)
{
}
