Resizing. Find a tutorial online of how to open the resizing tool in whatever program you're in. Then reset 16x16 to 125x125.

Side note: I don't think 125x125 is possible when making packs; the closest would be 128x128

 

Thats one major problem of a resourepack. Over my packs, I usually just continue the outline of the gun along the blur, seems to work great.

 

There's a filter called Oil Paint in the paint.net software. You can use that filter to merge the pixels of a 16x16 resource pack into 128x128.

 

And this is why I hate not having a windows. Too bad wine doesn't work with paint.

 

If using Paint.NET....
Go to Image -> Resize

Change the values here.

Remember to select Nearest Neighbor for Resampling or it turns blurry.
Choose By absolute size, then adjust as you wish. If you want to do it quickly, leave Maintain aspect ratio checked.
It's generally best to use resolutions divisible by 16 as they're easiest to do.
Common resource pack resolutions are:

• 8x (I'm serious)
• 16x
• 32x
• 64x
• 128x
• 256x
• 512x

So obviously, if you wanted the closest one to 125x you should make the image 128 pixels wide and 128 pixels tall.

And if you want a smooth looking 16x-styled pack....

 

What mac program are you using?

 

u forgot 69x69 i use it all the time so hd bruh

Pixelmator. I hate it so much.

 

Effects -> Artistic -> Oil Painting

 

Not sure, you can ask @gamemaster800. He uses that filter to create super-hd texture packs.

Edit: Brawler's ninjaed me. :V

 

You could use Gimp, (which I personally dislike for a number of reasons), but just cause I don't like it doesn't mean you won't too. And it's free.

 

I have it.
It hates me.
Thats why I wish I could throw it down an endless hole that goes deep into the fiery pit of hell.

 

Get photoshop like me
