WSH Cover专辑面板显示的图片如何设置收藏
看了帮助文档没有找到需要的提示。需求是这样的，我想让每一首歌曲播放时显示的专辑封面都是歌曲中的内嵌图片，而不是优先显示歌曲同文件夹下的某张*.jpg图片，这个功能如何实现呢？
看的不够仔细？
我觉得就是修改此属性，看帮助文档中写的是：====================================◆ Format附加图片来源路径。该选项内可以使用通配符，可用标题格式化，可以有多路径；多路径用“||”分隔；路径中你可以使用“%foobar_path%”来获取foobar2000程序所在的目录，返回值示例：“C:\Program files\foobar2000”；面板对此参数会先计算标题格式化，再检索“||”的位置进行切分，所以你可以使用诸如$if(%artist%,||E:\MusicPic\%artist%)这种脚本。====================================我想知道这个值【$directory_path(%path%)\*.jpg】中【(%path%)\*.jpg】什么意思，我就知道是文件夹下的任意jpg图片。内嵌图片的地址怎么写？
1.问题1那个wsh面板是专辑面板...?2.问题2我把所有面板都搜索了embed字符。只有如下代码开启来有点像还有下图代码剩下所有wsh面板都搜索不到代码...然后这两个地方怎么看也没有个先后顺序啊...
wsh cover脚本开头有清晰的注释说明的如果在前面加embeded不行的话，在fb2k设置-高级-显示，封面里有优先选择内嵌封面。
登录百度帐号获取图片中指定区域图片
最近在搞直接一个类似于二维码的东西，同样也是需要获取其中某个区域的图片。直接上最为主要的一些代码吧。
下面这个是初始化AV部分，这样就可以将图像在view上面展示了。这里简单的阐述一下在这其中碰到的问题和解决方法。
1.如果在layer上面搞出一个&洞 &，就是真正的裁剪区域，在这里用的是CAShapeLayer，利用fillMode，这样就可以通过mask方式作用在将覆盖在perviewLayer上面的coverLayer了。
2. 我们可以很容易的拿到整个的image，就可以在delegate中的sampleBuffer中拿到了。这里我使用的是AVCaptureVideoDataOutput，这样就可以不断的获取到采样的流了。
3. 从整个image中拿到裁剪区域中的图片。在这个问题上面花了不少时间和心思始终不能正确的拿到裁剪区域的图像。先是用了CGImageFromImage ，一个是才出来的图片位置和大小不对。之后转用cgcontext的方式。但是还是不太对。不断的使用google啊，怎么搞呢，琢磨啊。因为刚开始layer的呈现方式是fill的，这样实际的图片大小并不是和屏幕的大小是一样的。思前想后，可以确定是这个问题了，然后开始吧。针对不同的videoGravity的方式计算出裁剪区域实际在图片中对象的位置和大小，于是就有了一个calcRect的方法，这个方法就是将之前在屏幕上挖出来的&洞&对应到图片中的位置去。
总算是搞出来了。有兴趣的看看吧。
