Subject RE: newbie question regarding master db + file size
Date Thu, 12 Sep 2013 17:32:39 GMT
Hi Marcos, 
We’ve used the   javax.imageio.ImageWriter to significantly reduce the size of jpeg images.


A 4.2MB image at 30% quality is 1/10 the size and the differences are only slightly noticeable
from the original.

Here is how it the sizes differ  between 10-100% quality.

img-10.jpg	  200194
img-20.jpg	  288217
img-30.jpg	  375060
img-40.jpg	  453826
img-50.jpg	  542917
img-60.jpg	  621533
img-70.jpg	  819533
img-80.jpg	  990477
img-90.jpg	 1686143
img-100.jpg	 4251385

understood. thanks.

agreed. images already have that. again being a newbie i don't know how it is actually stored.
if its just the binary then it is fine. was more concerned about the other (if any) encodings.
