if you have zipfiles that do not work please attach these here so i can take a look
For example this one, with result of conversion

A question : do you know a way to convert many GIF files to PNG (one to one) ?

the files in the zipfile have defined color number 255 as transparent color
as far as i know it should be the color 0
if you google "convert many GIF files to PNG" i fopund many programs that can do that in the first page but i do not know if these tools optimizes the palette while converting the files
i myself have a python script for that

For conversions I can recommend XnView. There is a menu-driven interface (Tools/Batch processing) and also a command-line utility ("nconvert")

there is not much magic to it
Code: [Select]
from PIL import Image
import sys,os
for args in sys.argv[1:]:
    for root,dirs,files in os.walk(args):
        for f in files:
            if f.lower().endswith(".gif"):
                im=Image.open(f)
                im.save(fn[0:-4]+".png",optimize=False,transparency=0)
if you install python and PIL (or Pillow for python 3) you could just drag and drop a/some folder of images onto the script and it creates png files where it find gif files (overwrittes existing fuiles without conformition)
still think a gui tool is prefered by most but i cant say whats best there

However, I will try with python as I am really interested in learning to work with

I think I will need some help...

I installed Python 3.4
I ran easy_install-3.4.exe
I tried to install egg of PIL but it said it was already installed (2.5.1)
I create a .py file and paste your script (changed .gif to .GIF and .png to .PNG as I use uppercase extensions)
But when I drag and drop a folder containing GIF files, nothing happens
Any hint ?

EDIT : I put back gif and png instead of GIF and PNG

I succeeded taking a small (bad) screen capture of error message (1st screen shot)
I tried to rename first .GIF file to .gif but same result (2nd screen shot)
I created a folder with only one file all lowercase, same issue (3rd screen shot)

ups slight mistake in my code ( remember test before post :) )
Code: [Select]
from PIL import Image
import sys,os
for args in sys.argv[1:]:
    for root,dirs,files in os.walk(args):
        for f in files:           
            if f.lower().endswith(".gif"):
                im=Image.open(root+os.sep+f)
                im.save(root+os.sep+f[0:-4]+".png",optimize=False,transparency=0)

This works ! :D

And this global conversion showed me all GIF files that seem to not have right palette
Thanks again

EDIT : I am now able to play with all these sprites, modify them, create new one as I wish, ... I enjoy it a lot, thanks thanks thanks thanks thanks...

Linux users may use the ImageMagick toolset to merge a list of individual images into a spritesheet. (Win32 builds exist too, I believe)

$ montage ./hand*.gif -adjoin -geometry 32x40 -tile x1 -background transparent hadndob_unmapped.png
-- here all files beginning with hand were merged into 1-row sheet
may use -tile 32x for armor spritesheets (32 columns)

Note, that I'm naming my output 'unmapped', because the process reduces the palette, making it incompatible. Finally, this would require restoring the palette - I just paste the new spritesheet with GIMP into an existing valid image (one of the originals, with good palette), resizing it & removing the original layer; then save as new.

(manual on montage: https://www.imagemagick.org/Usage/montage/)

yeah i did saw the complicated gimp solution for palette fixing twice now
so i wrote a fixer for that issue
open https://falkooxc.pythonanywhere.com/palconvert
select the same palette in both dropdown menues
click more details
activate "try to fix palette colors"
and convert
that solves images with reduced palette but correct! colors that is the case in most of the wrong color- images
some images have wrong colors these colors are replaced by transparency (0) so such change should be obvious

So I'm trying to edit the HWP sprites for a mod that I'm making, which is a HWP compilation. I'm trying to make blue alloy tanks, and every time I've tried nothing happens and the template stays the same. I tried several times and still no dice. Mind showing me what's wrong?

I've followed the instructions in the first post by looking at docusprites and still nothing. They remain the same colour.

Falko, I was using your "sprite2png" tool like there was no tomorrow, and it went down.

I hope I haven't been too rough  :P


Edit:
Ok, it just resurrected :)

@Falko : perhaps you just ignore as it was a little bit nerving, but as you did not answer, I draw you attention at this question, especially the possibility to select an offset + size of range
