这篇文章给大家分享的是有关如何使用VBS调用Photoshop批量生成缩略图的内容。小编觉得挺实用的,因此分享给大家做个参考,一起跟随小编过来看看吧。
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###https://file.lsjlt.com/upload/202306/07/4f0fsew0eh1.jpg@@@/small/123.gif@@@8一***https://file.lsjlt.com/upload/202306/07/mnusxwq3efa.jpg@@@/small/456.gif@@@二***https://file.lsjlt.com/upload/202306/07/h55fhzrbzm3.jpg@@@/small/789.gif@@@三
格式解释如下:
0代表第0页出现图片点播;
https://file.lsjlt.com/upload/202306/07/4f0fsew0eh1.jpg是第一幅原图地址。/small/123.gif是第一幅缩略图地址,原图和缩略图名字一样,后缀不一样,原图是jpg,缩略图是gif。一是第一幅图片的说明文字;
第二幅、第三幅图片格式和第一幅图一样;
###、@@@、***为相应的分隔符。
-------------------------------------------------分割线--------------------------------------------------------
开始我是用手工来写这些图片格式,发现效率很低,一下午只发布了两篇新闻,就编写了相应的VBS脚本。
脚本一:采集新闻图片,并生成相应的图片格式代码
Directory = "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);
