RE: [PHP] thumbnail of webpage
I may have found something, a perl script that with all the appropriate pieces turns a page into a jpg image. http://marginalhacks.com/Hacks/html2jpg/ from there resizing using GD is a snap.

Doing this manually is simple, point your browser to your URL, and in windows use altprint Scrn to copy an image of the rendering in the browser to the scratch-pad, then paste the image into a tool like paint to cut out the part of the image you want, and use the skew/stretch tool in paint to create the thumbnail (GD is a good solution as well) saving the file as a jpg image. The difficulties with php is that opening the URL with fopen or using CURL allows getting the content of a page in html form, but provides no bitmap rendering of all that, let alone allowing JavaScript to alter the presentation as it would in a browser. What would be useful, if there were a way to open the URL in an IFRAME, and with JavaScript somehow capture a bitmap of the rendering of the web page, perhaps encoding the bitmap as mod64 characters and placing the result in a textarea for posting as input to a php script. This was the best solution that I could come up with but I don't have the skills to make this happen, yet. Question for anyone here, is does this sound like a path that might work? Can JavaScript access the rendered content of a webpage in window bitmap form? In my travels, someone had suggested coding something using mozilla and invoking it from a php script, but no one has done this yet that I can determine.

Re: [PHP] thumbnail of webpage
If you have a Linux box available here's something to try although it does have some required software. http://www.babysimon.co.uk/khtml2png/index.html There is also a link on the site for a commercial product for Windows that does the same thing. I can't endorse either one as I have not used them. Just giving the information.

RE: [PHP] thumbnail of webpage
Some great recommendations, but my first thought is wondering if you can interface with IE via COM or something. Or open the URL via IE and use the Windows API to do a PRINT SCREEN or ALT-PRINT SCREEN to capture it to the clipboard and do something funny that way. If I had time right now, I'd love to dig into this, but I wanted to at least share the thought in case it helped. Good luck! Let us know if you find a good way to do this via PHP. -TG -Original Message- From: Michael Mao [mailto:[EMAIL PROTECTED] Sent: Friday, September 17, 2004 7:54 PM To: [EMAIL PROTECTED] Subject: [PHP] thumbnail of webpage Is there a way to capture a snapshot of a html page and save it as a jpg using php? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] thumbnail of webpage
True, you'd have to run it on the web client end, but you can run IE on the server to access the HTML the server is err..serving. The server can also be a client, in other words. So your server can generate a thumbnail of what it's serving out by acting as a client for a second. As long as their security allows them to execute IE or interface with it and possibly the windows API. There are complexities, but it's the path I would explore if I had to create my own thumbnailing system (in the absence of some quick and easy utility that already did it). -TG -Original Message- From: raditha dissanayake [mailto:[EMAIL PROTECTED] Sent: Monday, September 20, 2004 12:28 PM Cc: [EMAIL PROTECTED] Subject: Re: [PHP] thumbnail of webpage Gryffyn, Trevor wrote: Some great recommendations, but my first thought is wondering if you can interface with IE via COM or something.

This is something that's very very hard to do with PHP but can be easily done with Java. Have not tried this but how about using 'import' which is part of the ImageMagick package? According to the man page: NAME import - capture some or all of an X server screen and save the image to a file. SYNOPSIS import [ options ... ] file DESCRIPTION Import reads an image from any visible window on an X server and out-puts it as an image file. You can capture a single window, the entire screen, or any rectangular portion of the screen. Use display for redisplay, printing, editing, formatting, archiving, image processing, etc. of the captured image. The target window can be specified by id, name, or may be selected by clicking the mouse in the desired window. If you press a button and then drag, a rectangle will form which expands and contracts as the mouse moves. To save the portion of the screen defined by the rectan- gle, just release the button. The keyboard bell is rung once at the beginning of the screen capture and twice when it completes. -- s/:-[(/]/:-)/g BrianGnuPG - KeyID: 0x04A4F0DC | Key Server: pgp.mit.edu == gpg --keyserver pgp.mit.edu --recv-keys 04A4F0DC Key Info: http://gfx-design.com/keys Linux Registered User #339825 at http://counter.li.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] thumbnail of webpage
First, im not sure how you would capture a snapshot of the page, sinse the page is rendered by the browser, and php is completely server side. Possibly there is a way to fopen a page or something, but... i dunno.. as for making thumbnail, using the gd extension, is quite easy. check the manual for GD.

* Thus wrote Michael Mao: Is there a way to capture a snapshot of a html page and save it as a jpg using php? As you can see this isn't an easy task. One possiblity is to ask the mozilla/gecko developers if it would be possible to to create a library that would render a page into a bitmap. If that is the case then PHP would be able to do what you need very easily.
