Hey

Has anyone got a graphics server running alongside ruby on rails? Kind  
of new to graphics rendering on a web server, so some general tips on a  
successful direction to go in would be great. I need it for automatic  
rescaling of images, similar to flickr.

Thanks,

RGC

Have you looked at ImageMagic  
([ImageMagick – Convert, Edit, or Compose Digital Images](http://www.imagemagick.org/script/index.php)) and rmagick  
([ImageMagick – Convert, Edit, or Compose Digital Images](http://www.imagemagick.org/script/index.php))?

Rmagick is ruby bindings for imagemagick.

Works great.

As indicated higher in the thread, the file\_column plugin is a  
no-brainer when it comes to resizing with RMagic.  
You only have to make sure that the original is not smaller than the  
target size (like resizing 16x16 =\> 100x100). It works - no crash or  
error -, but it doesn’t make sense, and the resulting mozaic is ugly.

An alternative is to resize in the browser with javascript.  
Example:

(note: look for the slider just above the pictures. It is not very  
visible in Safari.)

Try ImageMagick. It is a set of command line utitlities, and  
I think there is a rails implementation. If not, you can always  
exec the appropriate commands. Mogrify is probably the command  
line version you are looking for.
