Hi all- So first I wanted to announce a Ruby gem I created called magickly, which essentially offers Imagemagick as a web service. Please take a look - would love any feedback:
https://github.com/afeld/magickly As part of that plugin I include some pre-defined effects<https://github.com/afeld/magickly/blob/master/lib/shortcuts.rb>, i.e. tilt-shifting. I pretty closely mimicked the tilt-shift tutorial<http://www.imagemagick.org/Usage/photos/#tilt_shift>on the Imagemagick site, essentially running the following command: convert source.png \\( +clone -sparse-color Barycentric '0,0 black 0,%[fx:h-1] white' -function polynomial 2,-2,0.5 \\) \ -compose Blur -set option:compose:args 15 -composite output.png The result image looks good, but the app is serving photos on demand and it takes forever (upwards of 30 seconds for a 640x480 on my Mac). Turnaround time is more important than image quality here, so I was wondering if anyone had any ideas for how to speed this up? Here are a few ideas I had - no idea if they would make a difference: - linear gradients, as mentioned in the tutorial - storing the gradient map - using variable blur mapping<http://www.imagemagick.org/Usage/mapping/#blur> by creating two gradient:black-white squares to get something parametric-ish Any help would be appreciated. Thanks! -Aidan _______________________________________________ Magick-users mailing list Magick-users@imagemagick.org http://studio.imagemagick.org/mailman/listinfo/magick-users
