Resizing Images without the effort!

I found a sure way to make a image bigger(don't know if the trick works to make things smaller...sorry..)without it losing quality. Ever wanted to make a sprite you found on the net bigger...but couldn't because the pixels get all screwy? Well, fret no more!

*note, I'd recommend using something more powerful paint, something that adjusts image size up and down well without there being default options like Paint(now that I think about...making them smaller with this method might just work!). For this tutorial, I'll be using paint!

1. Open up Paint 2 times. One for the regular sprite, and the other blank.
2. Use the zoom button until you're satified(this is why something more powerful then Paint is recommended, like Gimp).
3. On the sprite, press Alt+PrintScreen.
4. On the blank image, paste the new image there, it will be the image with the sprite.
5. Outline the sprite and click copy.
6. Make a new blank image, then click paste.

Voila! The image has been "re-sized" to fit your needs. Nice to find loopholes in many things! If you aren't satisfied, I suggest using a image editor that allows you to adjust the "zoom-in, zoom-out" easily and freely.

Good luck!

Re: Resizing Images without the effort!

Honestly, just using stretch/skew in paint does the same thing. But you know, without the effort. It just uses nearest-neighbor interpolation. Whereas when I use GIMP, you can select one of None, Linear, Cubic, or Sinc (Lanczos 3).

You can try to hide yourself in this world of pretend; when the paper's crumpled up, it can't be perfect again.

True, but this method preserves the ACTUAL quality of the sprite or image.

I used that method before in I noticed that certain areas had a few more pixels added, making it look dingy. Not to mention you'd have to play with the numbers a bit..

Well in Paint (unless it changed with Windows 7) can only zoom 2x, 4x, 6x, and 8x. If you use those values (as percents) for them, it should look 100% the same. Only unequal increments should look weird at all.

Also, like I said, GIMP can use multiple methods. You can probably even add on more. Anyone know anything about doing that?

Re: Resizing Images without the effort!

Right, a better way is just to use Gimp’s Image → Scale Image, set the image size as some multiple of 100%, and use whatever interpolation you want.

Huh...I never really used those options. I guess it's worth a shot.

Re: Resizing Images without the effort!

Here are two additional resizing filters tailored for sprites.
Scale2x (3x) is excellent in how it does not introduce new colors to the image.

hq2x (3x) shades a bit, but it's much better at shapes than other filters.  Unfortunately, it does not preserve transparency.
