Hey there !
I've been looking a way to resize every tile in a tileset but didn't find any tool, so ... here is a script to do it :
from PIL import Image
import os
tileBaseSize = int(input("Tile base size ? (ex : 48)"))
tileNewSize = int(input("Tile new size ? (ex : 32)"))
for x in os.listdir():
if x.endswith(".png"):
# Read the image
im = Image.open(x)
width, height = im.size
newim = Image.new(mode="RGBA", size=(width, height))
i = 0
j = 0
for w in range(0,width, tileBaseSize):
for h in range(0,height,tileBaseSize):
# Image size
size = (tileNewSize, tileNewSize)
bx = (w, h, tileBaseSize+w,tileBaseSize+h)
print(bx)
# Resize image
out = im.resize(size,box=bx)
newim.paste(out, (i*tileNewSize,j*tileNewSize))
j = j+1
j=0
i= i +1
#newim.show()
# Save resized image
newim.save(str(tileNewSize)+"x"+str(tileNewSize)+"_"+x)
Prerequired :
Python3
Pillow library
Usage :
Put the script in a folder with tileset to resize, it will resize every tileset in folder and create new ones in the folder.
For instance :
I put my 48x48 tilset in my "ToResizeFolder", also my script in "ToResizeFolder".
I want my tileses to be 32x32 so I launch my script (on windows : python.exe .\ResizeTile.py)
It prompt me wich size is my base tileset so it's 48, press enter and which size I want my tileset instead, I enter 32 then press enter.
Here it is. Your file is named 32x32_thebasename.png
Well, cheers !
