Image file resize

Hi,

I need a utility that resizes images (nothing special so far) according
to a given output file size. So you select a picture of 500K, specify
that you want the output file to be 20K and the program calculates the
new image.

Anyone aware of a proggie that does this ??

The OP looks for a given _file_ size, not an image size.

This is close, if not an automatic cigar-winner...

The GIMP, when you go to save a file and are using the slider (mouse or
arrow keys) to determine the amount of compression you want to apply,
shows you the size of the resultant image. IOW, as you change the
compression from A to B, the expected image size field changes from
[file-size if A] to [file-size if B]. I can't think of any other
graphics utils I've used that do that; except for The GIMP, I've always
had to save-and-see. If others have offered this for me, I either never
noticed, or have forgotten.

A Smaller Image V2.0.0.8

http://www.dogbreathservices.com/freestuff.htm

I use this program to shrink pictures , then use IrfanView to make icons.

Put pictures in left pane, then use slider in right pane to get the size you
want. Not automatic.

You can also use the Plus and Minus in the left pane to cut the picture
down.

PicSizer 2.0

PicSizer is a utility for resizing images in batches and individually. It
was designed with owners of digital cameras in mind, but it can also be very
useful for designers and other people who work with images on a daily basis.
It's the perfect tool for quickly generating screen-friendly versions of
your images at dramatically reduced file sizes, and it's powerful yet easy
to use. PicSizer reads and saves in several popular RGB formats at any size
between 1 and 1024 pixels. ( These words are from the site )

For Windows 95 / 98 / ME / NT4 / 2K / XP

I just received the above in a news letter, so I have not tried it yet

How does Irfanview do what he is looking for?

JPEG2000 format will do it, but plugin has to be registered

Thanks, so far The GIMP wins the cake. It does what I need (plus loads
of other things, too ;) )

You're welcome -- happy to hook you up with a solution.

Once you get by the quirky user interface, it'll seriously grow on you.

I like the gimp, but the one thing I want to do, and cannot for the life
of me work out how to, is to use the gimp to resample a picture from
1200 dpi to 72 dpi. Is it at all possible?

Cheers,

Does Image/ScaleImage/PrintSize&DisplayUnit/Resolution help?

Nope. You can change the DPI, but that also changes the image size!

Doesn't matter, there's a free/register version of PSP 5 on the cover of
the October PC User mag here in OZ, I'll just use that under windoze.

On any computer, changing the DPI will change the image size displayed
because computers display pixels, but you can sometimes print at
whatever size you want and the program will simply enlarge/shrink the
pixels to accommodate. (May introduce some distortion.) DPI = dots per
inch.

Yes, I know, but what I want to do is re-sample the picture. Fuller
explanation follows.

I have a TIF image, x units by y units, scanned at 1200dpi, therefore
about 100Mb in size. I want to put it on a web page, but it is a bit
large, so, I want to change it to be 72dpi, but still x by y units in size.

This sort of thing usually involves some sort of calculation that not
only averages out a group of dots but also determines _which_ groups of
dots to average out, and weights the colour values as well.

And don't suggest "re-scan the picture at the required dpi."

Well, I can't think of anything that will do that free. I usually use
an old unregistered copy of Paintshop Pro from my Win3.x days to do
that kind of thing. (It's fast and easy, not like today's version.)
