[magick-users] Resize

[Nithin B.N.]

Hi,

Thanks

We are trying to reduce a .jpg file to 50% of its original size
We have a rose.jpg which is 1280 * 960

If we use
Convert rose.jpg -resize 50% rose1.jpg.

It reduces the dimension to 50 * 50, is there a way to reduce this this
600 * 300....I mean can it be possible reduce exactly by some %.

Regards,

The final filesize of any image is dependant on such a complex range of
image content, settings, compression, etc., that is is imposible to
simply ask for a file that is 'this size'.

The only way is by trail an error.

In particular you don't even mention what image file format you are
using!!!
