ImageResizer-转换PSD文件时出错-System.ArgumentException：参数无效

Question

I have a system where i upload single files to the webserver. Once uploaded i trigger a command to generate different sizes of the files.

The files uploaded are PSD and should be converted into pngs and jpgs.

The upload works fine and i can see the file in the directory. But when the "generate versions" command is fired i get this error

"file may be corrupted empty, or may contain a png image with a single dimension greater than 65535"

It's the line

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

The full command is

    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;
    }

and the variables fill until the error are:

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

here is the stack trace

Answer 1

When using the managed API with ASP.NET, but not the HttpModule, you need to call

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

in Global.asax.cs in addition to the following web.config settings

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

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

Otherwise the plugins will not be registered when you don't use the Http Modules.

You can verify the correct loading of plugins by calling

ImageResizer.Configuration.Config.Current.GetDiagnosticsPage()

This page also shows the supported filetypes (.psd, if plugin is loaded correctly).

Thanks to Nathanael (Owner of ImageResizer) for pointing me to this solution.

SOLVED

You need to add the following to you web.config file

<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" />

Actually, all you need to do is add <add name="PsdReader" /> to the <plugins/> section. The other stuff is only needed for the URL syntax, not the managed API.
