I'm not aware of a way that allows you to specify a file size, but you |
| 17 |
can use convert from media-gfx/imagemagick to re-compress and/or resize |
| 18 |
the files. For example: |
| 19 |
|
| 20 |
convert -quality 50 in.jpg out.jpg |
| 21 |
convert -resize 1000 in.jpg out.jpg |
| 22 |
|
| 23 |
The last command makes the image 1000px wide and sets the height |
| 24 |
automatically to the right value. |
| 25 |

Hope this helps, |
