标题 VBS调用Photoshop批量生成缩略图的代码
内容
    模仿腾讯新闻页，给KingCms添加了新闻页图片点播的代码，代码要求的图片点播格式如下：
    0###/uploads/202504/02/%ac%ac%e4%ba%8c%e5%b9%85%e3%80%81%e7%ac%ac%e4%b8%89%e5%b9%85%e5%9b%be%e7%89%87%e6%a0%bc%e5%bc%8f%e5%92%8c%e7%ac%ac%e4%b8%80%e5%b9%85%e5%9b%be%e4%b8%80%e6%a0%b7%ef%bc%9b%3cBR%3e     = "原始图"
    Directory = CreateObject("Scripting.FileSystemObject").GetFolder(".").Path & "\" & Directory & "\"
    Call DeleteFiles(Directory)
    strUrl = InputBox("请输入网址：")
    If strUrl <> "" Then
    Call getImages(strUrl)
    End If
    Function getImages(strUrl)
    Set ie = WScript.CreateObject("InternetExplorer.Application")
    ie.visible = True
    ie.navigate strUrl
    Do
    Wscript.Sleep 500
    Loop Until ie.ReadyState=4
    Set objImgs = ie.document.getElementById("fontzoom").getElementsByTagName("img")
    strTitles = InputBox("请输入图片配字：")
    arrTitles = Split(strTitles, " ")
    strCode = "0###"
    For i=0 To objImgs.length - 1
    If i>0 Then strCode = strCode + "***"
    smallPic = Replace(Mid(objImgs(i).src, InStrRev(objImgs(i).src, "/")+1), "jpg", "gif")
    strCode = strCode + objImgs(i).src + "@@@/small/" + smallPic + "@@@" + arrTitles(i)
    SaveRemoteFile objImgs(i).src
    Next
    ie.Quit
    InputBox "请复制结果：", , strCode
    End Function
    Sub SaveRemoteFile(RemoteFileUrl)
    LocalFile = Directory & Mid(RemoteFileUrl, InStrRev(RemoteFileUrl, "/")+1)
    Set xmlhttp = CreateObject("Microsoft.XMLHTTP")
    With xmlhttp
    .Open "Get", RemoteFileUrl, False, "", ""
    .Send
    GetRemoteData = .ResponseBody
    End With
    Set xmlhttp = Nothing
    Set Ads = CreateObject("Adodb.Stream")
    With Ads
    .Type = 1
    .Open
    .Write GetRemoteData
    .SaveToFile LocalFile, 2
    .Cancel()
    .Close()
    End With
    Set Ads=nothing
    End Sub
    Function DeleteFiles(strFolder)
    Set objFSO = CreateObject("Scripting.FileSystemObject")
    Set objFolder = objFSO.GetFolder(strFolder)
    Set objFiles = objFolder.Files
    For Each objFile in objFiles
    objFile.Delete
    Next
    Set objFSO = Nothing
    End Function
    脚本二：调用Photoshop批量生成缩略图
    Directory = "原始图" '原始图像的文件夹
    NewDirectory = "缩略图" '保存缩小图的文件夹
    Const psDoNotSaveChanges = 2
    Const PsExtensionType_psLowercase = 2
    Const psDisplayNoDialogs = 3
    Const psLocalSelective = 7
    Const psBlackWhite = 2
    Const psNoDither = 1
    limitHeight = 58 '最大高度
    ImgResolution = 72 '解析度
    Call DeleteFiles(NewDirectory)
    Call Convert2Gif(Directory)
    Function ReSizeImg(doc)
    rsHeight = doc.height
    Scale = 1.0
    if rsHeight > limitHeight Then
    Scale = limitHeight / (doc.height + 0.0)
    rsWidth = doc.width * Scale
    rsHeight = doc.height * Scale
    End If
    doc.resizeImage rsWidth, rsHeight, ImgResolution, 3
    End Function
    Function Convert2Gif(Directory)
    Set app = CreateObject( "Photoshop.Application" )
    app.bringToFront()
    app.preferences.rulerUnits = 1 'psPixels
    app.DisplayDialogs = psDisplayNoDialogs
    Set gifOpt = CreateObject("Photoshop.GIFSaveOptions")
    With gifOpt
    .Palette = psLocalSelective
    .Colors = 256
    .Forced = psBlackWhite
    .Transparency = False
    .Dither = psNoDither
    .Interlaced = False
    End With
    Set fso = CreateObject("Scripting.FileSystemObject")
    If Not fso.FolderExists(Directory) Then
    MsgBox "Photo Directory NOT Exists."
    Exit Function
    End If
    Set objFiles = fso.GetFolder(Directory).Files
    NewDirectory = fso.GetFolder(".").Path & "\" & NewDirectory & "\"
    For Each objFile In objFiles
    If Split(objFile.Name, ".")(1) <> "db" Then
    Set doc = app.Open(objFile.Path)
    Set app.ActiveDocument = doc
    ReSizeImg(doc)
    doc.SaveAs NewDirectory & Split(objFile.Name, ".")(0) & ".gif", gifOpt, True, PsExtensionType_psLowercase
    Call doc.Close(psDoNotSaveChanges)
    Set doc = Nothing
    End If
    Next
    Set app = Nothing
    End Function
    Function DeleteFiles(strFolder)
    Set objFSO = CreateObject("Scripting.FileSystemObject")
    Set objFolder = objFSO.GetFolder(strFolder)
    Set objFiles = objFolder.Files
    For Each objFile in objFiles
    objFile.Delete
    Next
    Set objFSO = Nothing
    End Function
    比较了一下，gif缩略图体积最小，所以就gif缩略图。关于VBS调用Photoshop，在Photoshop的C:\Program Files\Adobe\Adobe Photoshop CS4\Scripting\Documents目录下是说明文档，C:\Program Files\Adobe\Adobe Photoshop CS4\Scripting\Sample Scripts目录下是示例代码。如果要生成png缩略图，可以参考文档修改脚本相应的代码即可：
    Set pngOpt = CreateObject("Photoshop.PNGSaveOptions")
    With pngOpt
    .Interlaced = False
    End With
    开始打算是调用Set Jpeg = CreateObject("Persits.Jpeg")来生成缩略图，好处是不用加载庞大的Photoshop，生成缩略图速度很快，但比起Photoshop图片质量差了一些，就放弃了。
    本来的打算是不保存原图，直接打开网路图片，然后直接生成缩略图到本地。虽然Photoshop可以打开网络图片，但在脚本里调用Photoshop打开网络图片就不行，只好先保存网络图片到本地，然后再生成缩略图。
    其实Photoshop自带了图片批处理功能：
    窗口->动作->创建新动作->在PS中打开所有你想做的图片->选择其中一张图片，调整大小，另存为gif格式->关闭你已做好的图片->停止播放/记录。
    文件->自动->批处理->“动作”栏中选你刚刚新创建的动作名称->点“源”下面的“选择”选择你想要处理照片的文件夹->“目标”下面“选择”另外一个你想保存缩略图的文件夹->确定。就OK了！
    但比起程序来，显然程序要灵活的多，而且很多批处理效果只能靠程序实现，所以没有通过录制动作来生成缩略图。
    生成相应的图片格式代码，也可以在地址栏输入以下JS代码：
    javascript:D=prompt("图片配字","");E=D.split(" ");A=document.getElementById("fontzoom");B=A.getElementsByTagName("img");C="0###";for(i=0;i<B.length;i++){if(i>0) C+="***";C=C+B[i].src+"@@@/small/"+B[i].src.substring(B[i].src.lastIndexOf("/")+1).replace("jpg","gif")+"@@@"+E[i];}window.prompt("复制",C);void(0);
随便看
