Re: [Gimp-user] Scale Image

When you resize the image gets fuzzy as GIMP tries to squeeze the image 
into a smaller space. Play with the Unsharp Mask tool to sharpen it 
again. It can be found at Filters-Enhance-Unsharp Mask.
Settings to try: 0.1, 0.50, 4, but in general, if you really notice the 
sharpening then you've done too much!

In the lower portion of the image window, the second from the right
radio menu there -- marked with a percentage.  Change this from 100
percent to something smaller like 50% or even 25%.  Fitting the image to
the computer screen is different than scaling the image.  Scaling the
image is good for email or for web sites.

Yeah, I noticed that too.  You'd think they're unnecessary (the
millions of extra dots) - until you print.  Funny thing this world is.
 Annoying how you can get away with 72 dpi on a monitor, yet for
printing you need something like 4800x2400 dpi.  Can't tell until you
print... and if you don't ever print (you tell someone else to do so)
then it's really annoying.

Digital photo frame or physical (e.g. printing out)?

  when I Scale image to make it smaller?  If so, is

Yes, you are losing quality.  You reduce the number of dots in the
image, which reduces the number of dots per inch in the final
printout.  I'm assuming you're printing out, yes?

Of course, the type of scaling affects the accuracy of the loss... but
it's still loss, yes.

  there a way to reduce an image without losing
  quality?

Yes; change the DPI (dots per inch) in the Print Size dialog, instead
of using Scale.  It may help to uncheck dot for dot in the view/zoom
menu whatsit, so that you get an approximation of what it should
appear on paper size on the monitor (provided you gave it correct DPI
values when you configured GIMP the first time).  The values given in
the dialogue for size are pretty accurate too, provided your printer
supports them.

As a side note, IIRC Print in GIMP on Linux will adjust the size of
the picture by scaling up or down to the whole page by default if you
don't specify otherwise, and a print size can also be specified
there, I believe.  In Windows, because it uses the Windows print
dialogue, this is only specified in the Print Size dialogue, I
believe.

OS? (Operating System?)

Hope I was helpful.
