As some one pointed out already, the best way to resize pictures is to have a resizing tool. You may notice that most of the pictures shown here that
are "resized" are distorted. If you run XP get the
Image Resizer here:
www.microsoft.com...
This is only part of the solution, also get the
Power Calculator from the same site. It's much easier to work with.
Now you need a formula to help you resize pictures accurately to proportion. Try this:
(X/W)H=Y
Where:
X is the desired width
W is the original width
H is the original height
Y is the proportional height.
Let's say you have a picture to use an an avatar and it's too wide: 200x300. An avatar can be only 160 pixels, so you use this formula, as entered
on the calculator:
Now you can enter those dimensions into the
Image Resizer.
Here's an example where a picture is too narrow:
Apply the formula using the
Power Calculator:
(160/150)206=219.733333333333333333333333333
Enter 160 and 219 (always round down) into the
Image Resizer and voilà:
Notice that the
Image Resizer has taken care of the rounding error for you.
You can use the same formula with some adjustments to correct for height, as well.
I hope this helps.
