How To Reduce Pixels to 100 X 100

all-u-need · How To Reduce Pixels to 100 X 100

OK... since we have a little time before we post our next ad, I may as well learn how to do it properly.
By MUCH trial and error, I learned how to actually post an ad

but now I'm faced with another challenge.

Here's what it says in the pdf file kindly supplied by Bill and Debra:

"How To Post an Ad

4) Go for something that is 100X100 pixels or less."

Now that is fairly straightforward... BUT, I've been using photo's that are 640X480.
Sooo... thanks Bill, for, "looking the other way", first of all.

And secondly... how do I reduce a pic like I've been using to the preferred/required size?
I know that it's possible because I've done it before but I've forgotten how.
I used a standard program that came with Windows XP but not sure which one. And I also downloaded GIMP a while back (don't know why but I did) so that's also an option.
This question is a walk in the park for someone like Leon. So hopefully I'll be able to learn a new skill... very shortly.
Thanks

OK! Here's my update report...
Google is such a fine resource... but you already knew that...

Sooo... I'll quit clowning around and explain what I did. Sort of.
Using keywords that I've forgotten, something like "reduce pixels picture" I located this link:

http://www.werelate.org/wiki/Help:Images_and_annotation_tutorial

After clicking that link, you'll come to this headline:

2.1 Reducing pixels using Paint

Click on it and it'll take you to the instructions that I used.
However... it's misleading because I never found the instructions for Paint. Paint doesn't seem to have enough functions for this operation... at least in the XP version that I have.
In fact... I used the same free GIMP program that I downloaded such a long time ago and thought I'd never have a use for. So, you never know.
Bottom line... I was successful in reducing the pic mentioned in my previous post to these measurements:

100 pixels wide

75 pixels high

It took about 10 minutes in total.
The biggest challenge is in adapting the instructions from the "werelate" link, above, to the GIMP program. The terms used are similar but NOT exact. But if you think a bit you will be able to "fluke" your way through it.

Could I do it again... yeah. But it'd take about an hour or so to put it into words.

So hopefully this will suffice... at least for now.
The most important point is this! Make a copy of the image that you want to experiment on!!! That way, if you mess it up, you still have your original photo. AND... I'm not sure if it's possible to really ruin your original photo anyway... but I wouldn't want to bet on it

Also, the picture doesn't look all that much different in the 100X75 pixel size. At least as a thumbnail in, My Pictures. Haven't seen it posted online just yet though, obviously.
Hope that helps!
Later...

Hi Lorne,

Thank you for posting these instructions for everybody.

I have used Windows Paint many times to change the size of a picture.
That is how I reduced the size of my photo for the avatar in my forum posts.

It really isn't that hard to do.

1. Open the Paint program in windows.

2. Click "File" and then "Open"... your picture file should open so you can
browse for the picture you want to work with. When you have found
the image, first do a right-click and click "Properties". Write down the
size of the image and and then double-click the image.

3. In the Paint window, click "Image" and then "Stretch/Skew". This is
why you need to know the original size of the image. The one I chose
was 1600x1200 pixels. If you want an image that is 100x100 then you
will need to do a little math work.

I will show this so you can adapt it for yourself. In the Stretch/Skew
menu, you are presented with using percentages of the size. What you
will do is enter 100/the horizontal or width. In my case,100/1600=0.0625
or 6.25%. Then I would enter the integer 6 in the horizontal entry
location.

Then I would do the same thing with the vertical or height measurement.
Again, in my case, it would be 100/1200=0.0833 or 8.33%. I would then
place the integer 8 in the space for the horizontal.

BTW, this math will work for any size picture. If you want to reduce a
picture 640x480, just change the divisor to 640 or 480 respectively. In
that case, 100/640=0.1563 or 15.63% and use the 15 for the horizontal
entry. Likewise, 100/480=0.2083 or 20.83% and use the 20 for the
vertical entry.

If you want to make the picture 75x75 pixels, just divide 75 by the
original sizes. It really is that easy. Don't let the math bog you down.
I will do it for you if you will just ask.

4. Click "OK". You will immediately see the newly sized image in the
upper left corner.

5. Click "Image" again, but this time in the drop down menu click
"Attributes". You will see the size in the little boxes. In my case,
96x96 pixels.

BTW, if you forget to write down the size, you can still check to see what
size it is by doing the above attribute check.

6. Click "File" and then "Save As" to save your work to your
images folder with a NEW NAME.

You are welcome to copy and paste these instructions to a text file on
your desktop so you can open them while using the Paint program.

Happy re-sizing!

Peace to you and yours,

What I do is if you have
my document, bring up the picture
click file then edit, click at the
top again, image then attributes
in the box, make it an 80x80
and that pixel is marked as
choice. that's it...simple
just made this one real
quick...Need another one, cut
Johnny's head off, lol

Leon

Hi Cathy,

You can do that, but you are not getting the whole picture. It crops a portion of the picture and you are left with the problem of "cutting Johnny's head off".

I still recommend using the "Stretch/Skew" within Windows Paint.

Peace,

all-u-need

AHA!

Now you're talking.

Thanks Leon for those explicit instructions. Perfect.
I'll take you up on your offer and print it out.
Thanks to you also, Cathy.
GIMP wasn't too bad either though... it's a program that does have an "intuitive" feel to it.
Now we're all set!

I know Leon but it's simple
and Stud is prettier than Johnny
anyway, lol

Not really, Johnny's cute too
(just in case he reads this and it
is Valentines day)

Thanks for the added info, Leon. Great stuff.
OK... here's the update:
Just finished resizing 3 pix from 640X480 to 96X96 using Paint.
They all looked quite a bit better than the GIMP pic because there was more info... 96X96 instead of 100X75.
Annnd that is because GIMP uses an automatic slide adjustment which keeps the exact proportion of the original. So in essence, although GIMP keeps the pic in proportion it looks "fuzzier" or I suppose "softer focus" is a better term.
That's the trade-off... 96X96 is "taller" than the original but it does look better.
Will experiment with your additional file extensions tomorrow.
A productive post!

Leon

Lorne,

The proportional relationship can be maintained. You don't have to use a square dimension so long as the size is less than 100x100. Like I said, the math works. If you want to have the picture to have the same proportions, just reduce it by the same amount in each box.

width/640=height/480 (W/640=H/480) Substituting the maximum width of 100 pixels, we get the ratio of

100/640=H/480 now solve for H

(100/640)x480=H

(0.1563)x480=75

Width=100 and Height=75

The percentages would be 15 horizontal and 15 vertical and would produce a picture with a size of something slightly smaller than 100x75 pixels because we rounded down the actual percentages because the software only accepts integers (without decimal places).

So, the short version would be to simply reduce both horizontal and vertical by the same percentage after solving the equation to find out what percentage 100 is of 640. It is always the case of percentages when you divide the larger number into the smaller number. You will just move the decimal to the right 2 places to see the actual percentage instead of the decimal representation.

I hope you are not confused by all that I have tried to provide.

Peace,

all-u-need

Well Leon... for me there's math... and then the aftermath.
But in this case I think I'll be able to handle it.
Your efforts are MUCH appreciated. Not only by me but many others as well. I'm sure.
I'll get around to trying your formulas but it's been a very hectic day so far. Maybe by tonight I can start playing around again.
BUT... in fact, I don't really need to keep the original picture ratio. Square is fine and it probably looks better.
The only thing that confuses me is the computer geniuses that label a program "Stretch/Skew" when in reality we're "shrinking" the pic. At least in this case. Technically speaking they are probably more than correct with their description but it doesn't translate that way to the layman.
Numbnuts.
Anyway... that's my mini-rant for the day.

Thanks again!

And to think of all the 'HOURS' I spent trying to get a Pic to fit.

Can't even remember how I did do it now, so all those instructions will come in real handy.

Thank You All

Bern

Hi guys,

Sure glad I let Leon handle this one... lol

He is right on the money with it though.

Hi

My name is Rich Russell and I am brand new to Plan4Power. I'm here because I always think forums are a good place to start. You can learn a lot about a business from the people who are doing it.

Back to reason for post.

I use IrfanView. It's an excellent free, easy to use image editor. You can resize, crop, change format, add text to the image and all kinds of useful stuff. I haven't needed to refer to the help system to do what I have needed to do. Highly recommended. Get it here:
