Defining properties for multiple Textures

[zen4040]

I have about 2 hundred over sized textures and all I need to do is rescale to all to 0.5, I can't find a way to do it quickly enough so far when I look into the wiki, I'm supposed to define all of these 200 textures individually.

There must be a way to do apply the 2 scale to all of them...

Use the Batch Processing tool in XnView to resize all textures in one step.

it lowers the quallity of the textures, I've been trying to write a python script to create a textures file for me if I get bored with it I'll go for this I guess

that went faster than i expected. had to install the pillow module but I have a clean looking texture file now.

if anyone's interested, here's the code I wrote

from os import listdir, chdir
from PIL import Image

chdir("..\Textures")

cats = listdir()

Textures = str()

done = 0

print()

for cat in cats:
	chdir(cat)
	for texture in listdir():
		width, height = Image.open(texture).size
		Textures += "texture "+cat+"\\"+texture+", "+str(width)+", "+str(height)+" {\nXScale 2\nYScale 2\nPatch "+texture+", 0, 0\n}\n\n"
		done +=1
		print(done, end="\r")
	chdir("..")

chdir("..")
file = open("TEXTURES.txt", "w")
file.write(Textures)
file.close()

when I'm allready at it, as you can see I put textures in subfolder, to make it easier to navigate in gzdoombuilder, am I supposed to name the whole of the path to it? I'm worried the whole thing won't work at all with subdirectories
