Happy ImageMagick user here

Friday, November 28, 2008 by Dave Winer.

Everything is such a futz, but it's nice when these things have happy endings. I have my thumbnail creating app up, and while it's not linked into the RSS its going to be used in, that's the easy predictable stuff, the stuff that requires no futzing, at least not for me.  Permalink to this paragraph

Here's a folder of thumbs that ImageMagick is adding to every five minutes. Permalink to this paragraph

A picture named imneeeerdo.gifI'm doing it by launching the ImageMagick convert app, once for each picture. The fixed width is 100 pixels, I compute the height to be proportional. My script makes sure not to start another conversion until the previous file exists, because the process is unfortunately asynchronous. However it is easily synchronized. I have a 15 second timeout. Then I wait 5 seconds between conversions to let the CPU catch up processing other tasks. Image processing, esp for very large images, is a very CPU-intensive thing, apparently. Permalink to this paragraph

I hooted out loud (HOL) when I got it working. This one has been on my to-do list for a very long time! Permalink to this paragraph
