转换PSD文件时出错.参数无效

本文关键字：参数 无效 出错 PSD 文件 转换 | 更新日期: 2023-09-27 18:09:10

我有一个系统，我上传单个文件到web服务器。上传后触发命令生成不同大小的文件。

上传的文件为PSD格式，需要转换为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"命令被触发时，我得到这个错误

"文件可能被损坏为空，或者可能包含单个尺寸大于65535的PNG图像"

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:

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

这里是堆栈跟踪

转换PSD文件时出错.参数无效

在ASP. net中使用托管API时。. NET，但是不是 HttpModule，你需要调用

protected void Application_Start()
{
    ImageResizer.Configuration.Config.Current.Plugins.LoadPlugins();
}
Global.asax.cs中的

除了下面的web。设置配置

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

否则当你不使用Http模块时，插件将不会被注册。

你可以通过调用

来验证插件的正确加载
ImageResizer.Configuration.Config.Current.GetDiagnosticsPage()

此页面还显示了支持的文件类型(.psd，如果插件加载正确)。

感谢Nathanael (ImageResizer的所有者)为我指出这个解决方案。

SOLVED

您需要添加以下内容到您的web。配置文件

<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>

' T

实际上，您所需要做的就是将<add name="PsdReader" />添加到<plugins/>部分。其他的东西只需要URL语法，不需要托管API。
