Rails - Oct 2005 - RMagick reduce image quality (filesize)

Hi,

I''m using RMagick to reduce the image file size by

image.write("somefile") { self.quality = 50 }

It works fine, however, it needs to create another tmp file.
Since I''ll store the result in db.
Is it possible to conver the image object on-the-fly so that
no tmp file is necessary?

Gary

Gary,

Use to_blob: http://studio.imagemagick.org/RMagick/doc/ 
image3.html#to_blob

As in:

   pic = Magick::Image.from_blob(your_image_data){|img| img.format =  
"gif"}.first

   # ...do something with the image

   your_image_data = pic.to_blob { |img| img.format = img.format =  
"gif" }
