ImageResizer - 错误转换PSD文件 - System.ArgumentException：参数无效

Question

我有一个系统，我上传单个文件到网络服务器。一旦上传，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，应该转换成PNG和JPG格式。

上传工作正常，我可以看到目录中的文件。但是，当“生成版本”命令被解雇我得到这个错误

“文件可能已损坏空，或者可能包含一个维度PNG图像大于65535”

这行

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

完整的命令是

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; 
    } 

和变量填充，直到错误是：

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

解决

您需要将以下添加到您的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 2

事实上，所有你需要做的就是添加<add name="PsdReader" />到<plugins/>部分。其他内容仅适用于URL语法，而不是托管API。

Answer 3

当使用ASP.NET托管API，但不的HTTP模块，你需要调用

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

在Global.asax.cs中除了以下的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模块时插件将不会被注册。

你可以通过调用

ImageResizer.Configuration.Config.Current.GetDiagnosticsPage() 

该页面还显示了支持的文件类型验证插件正确加载（.PSD，如果插件正确加载）。
