获取Umbraco缩略图图像文件大小-Umbraco字节XSLT

我正在尝试获取ImageGen为图像库下载部分生成的缩略图jpg的文件大小

我以前在Umbraco 4.2中做过，但我正在尝试更新XSLT，并简化Umbraco 4.9中的XSLT

版本4.2方法：

<xsl:value-of select="emint:GetFileSize(((memberGroupFunctions:GetFileSize(concat(substring-before($mediaNode/data [@alias='umbracoFile'],'.'), '_thumb_1200.jpg')) div 1024) div 1024))" />

对于版本4.9，我正在尝试执行的操作：

<xsl:value-of select="emint:GetFileSize(((memberGroupFunctions:GetFileSize(concat(substring-before(umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoFile,'.'), '_thumb_1200.jpg')) div 1024) div 1024))" />

我不明白为什么它不起作用。原始图像被上传到媒体服务器，它被切割成各种大小，包括1200和2400。然后在内容部分使用媒体选择器数据类型选择原始图像。然后，我将它和thumb版本作为可下载链接显示在页面上。链接包括图像宽度、高度和文件大小。我就是无法在拇指图像上获得文件大小！显示宽度和高度。但是thumb图像的GetFileSize会导致解析XSLT文件错误

<ul>
        <li>
            <a href="{concat(substring-before(umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoFile,'.'), '_thumb_1200.jpg')}" title="Medium">
                Medium - <xsl:value-of select="emint:GetThumbailFileDimensionWidth(1200, umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoHeight div 1, umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoWidth div 1)"/> x <xsl:value-of select="emint:GetThumbailFileDimensionHeight(1200, umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoHeight div 1, umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoWidth div 1)"/> px
            <xsl:value-of select="emint:GetFileSize(((memberGroupFunctions:GetFileSize(concat(substring-before(umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoFile,'.'), '_thumb_1200.jpg')) div 1024) div 1024))" />
            </a>


        </li>
        <li>
            <a href="{concat(substring-before(umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoFile,'.'), '_thumb_2400.jpg')}" title="Large">
                Large - <xsl:value-of select="emint:GetThumbailFileDimensionWidth(2400, umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoHeight div 1, umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoWidth div 1)"/> x <xsl:value-of select="emint:GetThumbailFileDimensionHeight(2400, umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoHeight div 1, umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoWidth div 1)"/> px
                <xsl:value-of select="emint:GetFileSize((umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoBytes div 1024) div 1024)" />
            </a>
        </li>
        <li>
            <a href="{umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoFile}" title="Original File">
                Original File - <xsl:value-of select="umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoWidth" /> x <xsl:value-of select="umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoHeight" /> px
            - <xsl:value-of select="emint:GetFileSize((umbraco.library:GetMedia($currentPage/imageGalleryPhoto, 'false')/umbracoBytes div 1024) div 1024)" />
            </a>

下载列表应如何显示的示例：

中等-1200 x 898像素-225 KB 大尺寸-2400 x 1797像素-777 KB 原始文件-6658 x 4984 px-10.20 MB 这是我用于宽度、高度和文件大小转换的C脚本：

<msxsl:script language="C#" implements-prefix="emint">
<![CDATA[public string GetExtension(string fileName)
  { 
  string[] terms = fileName.Split('.');
  if (terms.Length <= 0)
  {
  return string.Empty;
  }
  return terms[terms.Length -1];
  }

  public string GetFileName(string fileName)
  { 
  string[] terms = fileName.Split('/');
  if (terms.Length <= 0)
  {
  return string.Empty;
  }
  return terms[terms.Length -1];
  }

  public string GetFileSize(Decimal mbs)
  { 
  Decimal result = Decimal.Round(mbs, 2);
  if (result == 0)
  {
  result = mbs * 1024;
  return Decimal.Round(result, 2).ToString() + " KB";
  }
  return result.ToString() + " MB";
  } 

    public Decimal GetThumbailSizeRatio(Decimal thumbnailSize, Decimal height, Decimal width)
    {
        Decimal ratio;
        if (height >= width)
        {
            ratio = height / thumbnailSize;
        }
        else
        {
            ratio = width / thumbnailSize;
        }
        return ratio;
    }

    public string GetThumbailFileDimensionHeight(Decimal thumbnailSize, Decimal height, Decimal width)
    {
        Decimal ratio = GetThumbailSizeRatio(thumbnailSize, height, width);
        return Decimal.Round((height / ratio), 0).ToString();
    }

    public string GetThumbailFileDimensionWidth(Decimal thumbnailSize, Decimal height, Decimal width)
    {
        Decimal ratio = GetThumbailSizeRatio(thumbnailSize, height, width);
        return Decimal.Round((width/ ratio), 0).ToString();
    }   

  public string GetCentimeters(Decimal pix)
  {

有人能帮忙吗

干杯，JV

你能用它来生成图像吗

如果是，您必须安装ImageGenerator。这是一个非常有用的工具，可以生成任意大小的图像，您需要在软件包中的Umbraco CMS from Developer部分安装

此外，还有关于如何使用的文档

我希望这将有助于

我使用ImageGen创建缩略图。谢谢你的发帖。
