RE: Resizing images under Linux
Hi, Indeed, ImageJ is another imaging Java library, it is easier to use than JAI. It supports GIF and it is the world's fastest pure Java image processing program. It can filter a 2048x2048 image in 0.5 seconds. That's over 8 million pixels per second!. If you look at Todd's ones and my examples (http://www.benorama.com/coldfusion/libraries/imaging.htm), you'll see that it is very easy to use from CF. I don't know about the quality of the generated thumbnails compared to JAI ones...

Re: Resizing images under Linux
Thanks for all your suggestions everyone. I think CF_ImageMagick is the way I'm going to go, as it seems to do everything I want, I already have ImageMagick installed on my server, and I don't have to write any fancy code other than that handles the automatic creation and caching of thumbnails... basically a custom tag I'm calling CF_THUMBNAIL. Assuming a file named '97.jpg' is 500x733, CF_THUMBNAIL FILENAME=/home/rickroot/www/photo_gallery/97.jpg WIDTH=100 will generate IMG SRC=/photo_gallery/thumbnail_97.jpg WIDTH=100 HEIGHT=146 the CF_THUMBNAIL custom tag will automatically check for the existence of the thumbnail image, and compare it's date to the original file.. and generate a new thumbnail only if necessary. It generates the thumbnail image with dimensions specified, and will scale evenly by detecting original size using the CF_IMAGESIZE tag I found in the developer's exchange. - Rick ~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribeforumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Signup for the Fusion Authority news alert and keep up with the latest news in ColdFusion and related topics. http://www.fusionauthority.com/signup.cfm
Problems with dynamically generated images... (was Re: Resizing images under Linux)
Okay... so I'm using CF_MagickTag to generate my thumbnails, and it's doing an admirable job of it. HOWEVER, the image doesn't appear properly the first time a thumbnail is generated... it's almost as if the page is loading BEFORE the thumbnail is completely generated. For an example, go here: http://www.rickroot.com/photo_gallery/test.cfm?WIDTH=200 Change the WIDTH attribute in the URL to something else... like 105 or 51 or 423... If you load the page (and you're the first person to choose a certain dimension), you'll see a broken image. Right click and choose Show Picture and the image shows up just fine.. or reload the page, and it shows up just fine. Anyone here got any ideas what might be going on? - Rick ~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribeforumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Signup for the Fusion Authority news alert and keep up with the latest news in ColdFusion and related topics. http://www.fusionauthority.com/signup.cfm

Goodness... you know I hadn't even thought to test it in Mozilla yet (I do all my development with IE, but I actually use Mozilla as my primary browser when I can). Sure enough, it works fine in Mozilla.

RE: Resizing images under Linux
I read that article before, and it looks to me that the huge downside of JAI is the lack of GIF support. it can write BMP, JPG, TIF, PNG, but if you must write GIF files, then you ll have to find another implementation (note that the PNG file format is an acceptable substitute for GIF file format). I would love it if PNG were an acceptable substitute, but it's implementation in browsers seems worse than CSS. -Kevin -Original Message- From: Sean A Corfield [mailto:sean;corfield.org] Sent: Tuesday, November 05, 2002 1:47 PM To: CF-Talk Subject: Re: Resizing images under Linux Check out JAI - the Java image library.
