turn a web page into an image with ColdFusion, Java or command line utility?

问题

Native ancient solution in ColdFusion that used to work with HTML 3.x...

<cfhttp url="#targetUrl#" resolveurl="yes"> 

<cfdocument format="pdf" name="pdfVar">
    #cfhttp.filecontent# 
</cfdocument> 

<cfpdf action="thumbnail" source="#pdfVar#" pages="1" destination="image">
<cfimage action="writeToBrowser" source="#image#">

Super slow, even with cache, many CSS styles missing or broken.

Any good server-side solution to capture a rendered webpage into a thumbnail? like service provided by http://www.shrinktheweb.com/ ?

Any ColdFusion, Java or Command line utility solution?

回答1:

This website has a script that does what I think your looking for, I haven’t tried using it for any server-side project though.

http://khtml2png.sourceforge.net/

Doesn’t make thumbnails though, but you could render the image created with cfimage.

If you have ColdFusion version 8 or better, you can simply use CFDOCUMENT to create a thumbnail.

From Ray's post:

<cfdocument src="http://www.coldfusionjedi.com" name="pdfdata" format="pdf" />
<cfpdf source="pdfdata" pages="1" action="thumbnail" destination="." format="jpg" overwrite="true" resolution="high" scale="25">

We ended up using SiteShoter which uses IE as the renderering engine. http://www.nirsoft.net/utils/web_site_screenshot.html
