Sitecore 'getMediaStream' 不工作

Question

现在我正在使用 Dianoga (https://github.com/kamsar/Dianoga) 进行图像压缩。此工具适用于 png 和 jpg/jpeg 文件，PNG 文件工作正常。但是，如果我上传 JPG 文件，上传工具框会像屏幕截图一样冻结。

这是执行线。

var jpegtran = Process.Start(ToolPath, " -optimize -copy none -progressive -outfile \"{0}\" \"{0}\"".FormatWith(tempFilePath));

如果我像这样更改代码，

var jpegtran = Process.Start(ToolPath, " -optimize -copy none -progressive -outfile \"{1}\" \"{0}\"".FormatWith(tempFilePath));

JPG 文件已更新，但未进行压缩处理。日志说，

"ERROR Could not run the 'getMediaStream' pipeline for '/sitecore/media library/Images/satellite-westtibet'. Original media data will be used"

这是我在 /App_Config/Include/.

中的 web.config 文件

宽度和高度为空值时出错

问题终于解决了。问题是我必须“解锁” jpegtran.exe 文件。就是这样。
