Re: [Gimp-user] how to scale down image without quality loss

For scaling down vector images, use Inkscape.
Otherwise, if you still use GIMP, make sure that you import the image at 300dpi and resize from that - but 
for a better visual result, I highly suggest using Inkscape

Hi there,
Hope you can help me with this as I’ve tried everything!
All I am trying to do is scale a large .EPS logo which is 1.2Mb and
imports into Gimp 2.8.14 at 100dpi?, Width 826 and Height 1170 with no
Anti-Aliasing, down to a logo of around 28mm high without losing too
much image
quality.  What I get using the standard scale command in Gimp is a
degradation and very fuzzy logo outlines.

I’ve been ‘trying’ to use Liquid Rescale, the gimp plugin, but it comes
with two error boxes…

Any suggestions?  I don’t have to use the LR plugin but from what I’ve
read it
seems the only way to do this well with Gimp.


Liquid Rescale is a tool for 'stretching' images to a new aspect
ratio (i.e. making them wider but not taller), without affecting
selected elements of the image or creating visible seams.  It can
also be used to remove parts of an image without visible distortion.
 I don't think it's the best option for radical re-scaling with
minimum distortion.

I would try the Script Fu 'Step Resize' tool for that.  But the GIMP
is probably not the right tool for the job at hand.

The EPS file format is normally a vector file, that is, more like a
CAD drawing than a digital photograph.  From Wikipdeia:

"An EPS file is a stream of generic PostScript printing commands."

EPS files also (usually) have thumbnail images embedded in them;
again per Wikipedia:  "EPS files also frequently include a preview
picture of the content, for on-screen display."

A logo that is a 1.2 MB EPS file probably has a /big/ preview image;
vector graphic files are normally a tiny fraction of the size of an
equivalent bitmap image file.  But I don't think that's relevant to
solving your problem.

The first thing I would try is opening the EPS file in a vector
graphics editor like Inkscape.  This /should/ enable you to export
bitmap copies of the logo at any scale, with the best resolution
possible for the size in question.  This flexibility is why logos
are normally created as vector files; the same vector graphic source
file can be used to make matchbook covers and billboards.

Hopefully this will get the job done.


Any help much appreciated.

By the way, I’d prefer someone in my own time zone in Eastern Australia
(GMT +
10 hours) if possible.
