Question

我有一个系统，我将单个文件上传到网络服务器。上传后，我会触发一个命令来生成不同大小的文件。

上传的文件是PSD，应该转换为pngs和jpgs。

上传工作正常，我可以在目录中看到该文件。但是当“生成版本”命令被触发时，我得到了这个错误

“文件可能已损坏为空，或者可能包含单个维度大于65535的png图像”

这是一行

generatedFiles.Add(ImageBuilder.Current.Build(file, strDestinationPath, objResizeCommand, false, true));

完整命令是

    public IList<string> GenerateVersions(decimal id, string file, string filename)
    {
        List<string> generatedFiles = new List<string>();

        foreach (var tCmdSets in db.IMG_SETTINGS_CMDSETS.Where("it.SETTINGS_FOLDER_ID = @folderid", new ObjectParameter("folderid", id)))
        {
            var strDestinationPath = ImageResizer.Util.PathUtils.RemoveExtension(Path.Combine(tmpDefaultFolder, tCmdSets.SETTINGS_CMDSET_DESTINATION, filename));
            ResizeSettings objResizeCommand =  new ResizeSettings(tCmdSets.SETTINGS_CMDSET_COMMAND);
            generatedFiles.Add(ImageBuilder.Current.Build(file, strDestinationPath, objResizeCommand, false, true));
        }
        return generatedFiles;
    }

并填充变量，直到错误为：

file    "c:\\www\\upload\\masters\\Products\\upload_test.psd"   string
objResizeCommand    {?maxwidth=800&maxheight=600&format=jpg}         ImageResizer.ResizeSettings
strDestinationPath  "c:\\www\\upload\\converted\\items\\big\\upload_test"   string

这是堆栈跟踪

Answer 1

在ASP.NET中使用托管API但不 HttpModule时，需要调用

protected void Application_Start()
{
    ImageResizer.Configuration.Config.Current.Plugins.LoadPlugins();
}

Global.asax.cs 中的

以及以下 web.config 设置

<configSections>
   <section name="resizer" type="ImageResizer.ResizerSection"  requirePermission="false"  />
</configSections>

<resizer>
  <plugins>
    <add name="PsdReader" />
  </plugins>
</resizer>

否则，当您不使用Http Modules时，不会注册插件。

您可以通过调用

来验证插件的正确加载

ImageResizer.Configuration.Config.Current.GetDiagnosticsPage()

此页面还显示支持的文件类型（.psd，如果插件已正确加载）。

感谢Nathanael（ImageResizer的所有者）指出我的解决方案。

解决

您需要将以下内容添加到web.config文件

<configSections>
   <section name="resizer" type="ImageResizer.ResizerSection"/>
</configSections>

<resizer>
<sizelimits  />
<diskcache enabled="false" />
<remotereader signingKey="ag383ht23sag#laf#lafF#oyfafqewt;2t w  eyfwfefwqefqw" allowAllSignedRequests="true" />
<plugins>
  <add name="DiskCache" />
  <add name="PsdReader" />
  <add name="PrettyGifs" />
  <add name="Image404" />
  <add name="AnimatedGifs" />
  <add name="Gradient" />
  <add name="SimpleFilters" />
  <add name="RemoteReader" />
  <add name="AdvancedFilters" />
  <add name="CloudFront" />
  <add name="SeamCarving" />
  <add name="FolderResizeSyntax" />
  <add name="ImageHandlerSyntax" />
  <add name="MyCode.MyPlugins.SamplePlugin" />
  <add name="WhitespaceTrimmer" />
</plugins>
</resizer>

<httpModules>
  <add name="ImageResizingModule" type="ImageResizer.InterceptModule"/>
</httpModules>

<modules runAllManagedModulesForAllRequests="true">
  <add name="ImageResizingModule" type="ImageResizer.InterceptModule"/>
</modules>

Answer 3

实际上，您需要做的只是将<add name="PsdReader" />添加到<plugins/>部分。其他内容仅用于URL语法，而不是托管API。
