请问如何实现给图片加图片边框也就是相框

[netboygg]

请问怎么用C#实现给图片加上边框也就是相框。就像：


这种相框，把目标图片镶嵌在里面，谢谢。

[dylike]

1　建立临时图片
2　在1上绘制照片
3　在1上绘制相框

[黄亮]

首先放个Panel，将边框图片作为背景backgroundimage
然后里边放你的照片picturebox，拉伸到适当大小。再将PictureBox的Anchor设为Top, Bottom, Left, Right

[netboygg]

上边的图挂了，就是这种相框。。。。。。。。。。

[bdmh]

可以将相框作为底图，然后在上面贴图，当然还可全部绘制上去

[娃都会打酱油了]

简单的说就是两张图合成一张图吗。。。。网上查一下打水印的方法就知道啦

我在网上找了个代码 加图片水印的：

效果确是这样的：

原图：

相框：

[netboygg]

this.iDiaphaneity = 50;//图片水印透明度
这个数 怎么调都不对，要么中间一片黑，要么 相框图也是透明的才能看见里面的原图。

[netboygg]

我知道为什么了 相框图和原图的先后顺序不对。谢谢

[卧_槽]

边框可以是整张中间透明或者半透明的png图片。也可以是多张图片的组合编排。最后用gdi+绘制到原图上去。

[Daqing]

        private Image ReGrahp(string sourcefile)
        {
            Image SourceImage = Image.FromFile(sourcefile);
            Image bmp = new System.Drawing.Bitmap(@"C:\Users\Administrator\Pictures\143097_1320710793tp40.jpg");//这里是背景图片
            Size size = new Size(new Point(bmp.Width-58, bmp.Height-50));//这个是源图片的加载宽度和高度

            Graphics g = Graphics.FromImage(bmp);
            g.DrawImage(SourceImage, new Rectangle(28,30, size.Width, size.Height), 10, 10, SourceImage.Width, SourceImage.Height, GraphicsUnit.Pixel);//Rectangle为 30距离顶部和 28左边的距离。
            return bmp;
        }

[帮帮你我她]

先放个Panel， 背景色，设成你需要的边框色，
再放一个图片入其中，将两个尺寸设成一样，图片的定位点设为0,0,即可
