图片转成流 Bitmap b = new Bitmap(Server.MapPath(ppath)); Stream ms = new MemoryStream(); b.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); 流转成图片 MemoryStream ms = new MemoryStream(Bytes); return Bitmap.FromStream(ms,true); 字节转图片 /// <summary> /// 字节数组
具体实现代码如下: 1.新建一个一般处理程序: Image.ashx using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Net; using System.Drawing.Imaging; using System.IO; namespace Test { /// <summary> ///测试图片以二进制字节输出到HTML页面(显示成图片) ///
一,效果图. 二,工程图. 三,代码. ViewController.m - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. //初始化界面 [self addView]; } #pragma -mark -functions //初始化界面 -(void)addView { UIImageView *imageVie
