Hi all...

I have no doubt this has already been discussed a MILLION times before but
anyone mind if we do it again?

I use ULEADS web razor suite of programs (usually) to reduce graphics for me
which does a great job but it FRUSTRATES me no end that I cant reproduce the
quality of the graphic MANUALLY that it produces..

For example....I have just reduced some CorelDraw 9 vector graphics by
turning them into TIF files via photopaint the typical starting size was
1550Px x 1154 Px @ 300 DPI...now obviously each one of these would have
taken like an HOUR to download so A LOT of reduction was necessary but they
were very good quality graphics....

I started by converting them to 256 colours then reducing the DPI down to
96DPI and then reduced the size to what I needed (around 450Px wide) this
produced the size files I needed but the graphics looked absolutely LOUSY.

After playing for a while with other settings I ended up doing just a 50%
resample as a full colour TIF in Photopaint and then opening the file in
ULEADS Smartsaver pro and further resampling to 450Px wide....the resultant
file was SMALLER than the one I had originally produced from Photopaint but
looked much MUCH better.

My question....

Is there a particular way one should resample a graphic in a paint program?

Why cant I get the same quality by doing it manually...am I doing something
wrong?

I've been doing this for a couple of years now and it has always puzzled
me....
( By the way I am talking about the QUALITY of the graphic ....everything
was in the proper proportions wasnt sqeezed up or anything)
Over to my Bettors.....

Thanks
