C# 2.0如何实现DrawImage生成图片二进制(*bin)输出

Question

我在写一个程序，C#2.0，想通过DrawImage绘图生成的图片文件以二进制格式输出，后缀名为.bin，请高手给点思路，谢谢！

Answer 1

图片的数据是怎么存储的？可以用BinaryWriter类来操作试试直接将数据以二进制的方式写入文件

Answer 2

可以把Image对象里面的BitMap提出来 生成byte[] 然后就喜欢怎么就怎么搞吧
加载的时候可以Image.FromStream
很强大

Answer 3

我的代码如下，请高手具体指点一下private void MakeImageFile(string iname ,string family_num,string cell_num,string office_num,string sht_num,string fax_num,string uimg,string bg)
        {
            string name = iname;
            string familyn = family_num;
            string celln = cell_num;
            string officen = office_num;
            string shtn = sht_num;
            string faxn = fax_num;
            string uimgpath = uimg;
            string bgimg = bg;            string ext_First = ".card";
            string ext_Second = ".tel";
            string[] filenames = { familyn, celln, officen, shtn, faxn };
            bool isFirst = true;            string imgpath = Application.StartupPath;
            string bg_img = imgpath + "\\BgImages\\" + bgimg;
            Font drawFontName = new Font("宋体", 20);
            Font drawFont = new Font("Arial Black", 20);
            SolidBrush drawBrush = new SolidBrush(Color.DarkBlue);
            
            if (System.IO.File.Exists(bg_img) && System.IO.File.Exists(uimgpath))
            {
                Image bmp = Image.FromFile(bg_img);
                Image userimg = Image.FromFile(uimgpath);
                Graphics g = Graphics.FromImage(bmp);
                g.DrawImage(userimg, 220, 5, 95, 103);
                g.DrawString(name, drawFontName, drawBrush, 5, 5);
                g.DrawString(familyn, drawFont, drawBrush, 5, 40);
                g.DrawString(celln, drawFont, drawBrush, 5, 75);
                g.DrawString(officen, drawFont, drawBrush, 5, 115);
                g.DrawString(shtn, drawFont, drawBrush, 5, 150);
                g.DrawString(faxn, drawFont, drawBrush, 5, 185);                for (int i = 0; i < 5; i++)
                {
                    string fname = filenames[i];
                    string filename = "0";                    if (fname != "")
                    {
                        if (isFirst)
                        {
                            if (fname.Length >= 8)
                            {
                                filename = fname.Substring(fname.Length - 8, 8) + ext_First;
                            }
                            else
                            {
                                filename = fname + ext_First;
                            }
                        }
                        else
                        {
                            if (fname.Length >= 8)
                            {
                                filename = fname.Substring(fname.Length - 8, 8) + ext_Second;
                            }
                            else
                            {
                                filename = fname + ext_Second;
                            }
                        }
                        string newImg = imgpath + "\\Images\\" + filename;
                        bmp.Save(newImg);
                        isFirst = false;
                    }
                }
                bmp.Dispose();
                userimg.Dispose();
                g.Dispose();
            }
        }

Answer 4

把图片读入type数组里！！然后以.bin为扩展名保存就行！！

Answer 5

我这样生成的文件可以直接预览图片，而用Image2Lcd转换后的bin文件不能直接预览，无法显示呢？
请问该如何实现？

Answer 6

你保存的bin文件系统不认识，比如bmp这种通用的图片文件格式，都是有默认打开方式的
