“vcopenpng.zip” 里不是有格式 吗， 你要 修改 png 现在 可以 用 “绘图”，他可以打开和保存 png 文件。

13楼不是一个二进制png， 只是这个 png 的 txt 表示。 而且 格式也 不对 ！参考 #3 ，那是 png 的 头几个 字节。

这样说吧：你在cpp里看到： unsigned char g_ucSysButtonCloseNormal[] = { 0x89,0x50,0x4e,0x47,0x0d,0x0a,0x1a,0x0a,0x00, 是因为每个字母都是 ascii 。 但编译后 g_ucSysButtonCloseNormal[] 里都是二进制数。 如 "89" ascii 是 ‘8’（=48+8）‘9’（=48+9） 2个 字节，编译器 把'89' 变成 一个字节 （137) //0x89 所以在程序使用 g_ucSysButtonCloseNormal[] 是二进制的数组，你可以把他直接写入到一个.png 文件。 如果你 拷贝： 0x89,0x50,0x4e,0x47,0x0d,0x0a,0x1a,0x0a,0x00,。。。 到剪贴板， 然后 粘贴到 一个新文件 .txt ,你得到 g_ucSysButtonCloseNormal[] 的 ascii 表示方法。

png 文件本身就是 binary 的。 你可以 用 ue 按 Hex 显示。 自己 转换 成 ascii 的 也可以。

“数组数据复制.txt里” 2种文件不是 一个格式。 txt 是给人看的，所以是 ASCII 数组里数据 是 二进制 格式。是给机器看的。 要把 binary 转换到 hex

要分析png格式 BOOL CVcOpenPNG::IsValidSignature(BYTE Signature[]) { if(Signature[0] != 137) return FALSE;//0x89 if(Signature[1] != 80 ) return FALSE;//0x50='P' if(Signature[2] != 78 ) return FALSE;//0x4E='N' if(Signature[3] != 71 ) return FALSE;//0x47='G' if(Signature[4] != 13 ) return FALSE;//0x0D if(Signature[5] != 10 ) return FALSE;//0x0A if(Signature[6] != 26 ) return FALSE;//0x1A if(Signature[7] != 10 ) return FALSE;//0x0A return TRUE; }

SV学习笔记（八）-数组
由于处理器在访问存储时的访问时随机散乱的，这意味在整个测试中，处理器也许只会访问几百个存储地址，而剩下大多数地址都将被初始化为0，浪费了仿真时的存储空间。SV引入了关联数组，可以用来存放散列的数据成员，这一点于其它脚本语言Perl或python类似，散列的索引类型除了。SV页保留了Verilog索引非组合型数组或者数组片段的能力，这种方式为数组及数组片段的拷贝带来了方便。组合型数组会进一步规范数据的存储方式，而不需要关心编译或者操作系统的区别，数据是连续存放的。with查找满足条件的数据成员更方便。
PNG文件结构(PNG图片格式)详解(转)
PNG文件结构(PNG图片格式)详解(转) 2010年08月09日 　　PNG文件格式分为PNG-24和PNG-8，其最大的区别是PNG-24是用24位来保存一个像素值，是真彩色，而PNG-8是用8位索引值来在调色盘 中索引一个颜色，因为一个索引值的最大上限为2的8次方既128，故调色盘中颜色数最多为128种，所以该文件格式又被叫做PNG-8 128仿色。PNG-24因为其图片容量过大，...
C#下怎样处理并保存单色格式PNG图片？
  用微软自带的画图，打开一个已经存在的单色PNG图片文件，然后复制图像粘贴上去，做点反色或其他处理再保存，可以得到黑白单色PNG图片；但是，如果有很多黑底白字的图片要想改成白纸黑字的单色PNG格式保存这就很麻烦了，譬如2,3百张BMP或JPG图片用来保存只有白纸黑字的书页真是浪费。可是，有些索引格式图像如单色位图，或者单色PNG，如果用C#的Graphics类处理之后，保存文件只能得
