My graphics designer has made graphics in separate PNG files. Is there a clever tool/script that mashes them into a spritesheet?

I could probably code something myself, but why re-invent the wheel :)

  • I don't think it's a dupe. At least not of that question; I'm pretty sure I've seen this question before but I can't remember where. Anyway that question does generally encompass this one, but this question is more specific. – jhocking Apr 11 '12 at 16:43

    @jhocking If you can post an answer to that question that is verbatim to the answer you've posted here. They are duplicates :) – House Apr 11 '12 at 18:17

    That's not a good rule at all. Just to be ridiculous: What is 2 + 2? What is 8 - 4? OMG SAME QUESTION – jhocking Apr 11 '12 at 19:27

    More serious response: My answer is exactly the same, sure, but the accepted answer there is completely unrelated to this question. My answer applies in both places because this question is a specific case of that question; that question asked "any tools for any sprite tasks?" and this question is "tool for this one specific task?" Honestly my answer applies more here; I should've just made it a comment to someone else's answer there. – jhocking Apr 11 '12 at 19:42
  • @jhocking This question here isn't more specific. Creating sprite-sheets is about packing lots of images into one "atlas". So all the answers in the existing question apply.. if the question was about optimal packing algorithms or had more details to it, then maybe it would warrant it's own answers. As of now this isn't the case. – bummzack Apr 11 '12 at 22:04

    The accepted answer there doesn't make any reference to packing lots of images into one atlas. You don't have to take my word for it, you can go and read it. That question is nominally about spritesheets because they are mentioned in the title, but the question is mostly about animation techniques for generating the frames used in a spritesheet. – jhocking Apr 12 '12 at 00:04

Am I the only one who uses SpriteSheetPacker? It's free and open source so you can modify it and learn how it works.

I've been using TexturePacker to create sprites from a folder of PNG images. I'm porting a game originally developed in Flash, so I'm simply exporting each frame of the MovieClip to png and then importing those images in Texture Packer.

Another similar tool is Zwoptex

(The latter is Mac software, but TP has a version for Windows too.)

ImageMagick has a command line utility that can join images into what it calls a "montage." It can be tiring getting the right command line parameters to do what you want, but it's a very powerful and flexible tool. I use it very frequently for building spritesheets.

I have decided to open source my 2D spritesheet and animation tool. It supports automatic sprite selection, combining images, sprite grouping, and multi-sprite animation with rotation.

It is written in Java, the github repo is here: https://github.com/darkFunction/darkFunction-Editor

Website for the project is: http://darkfunction.com/editor

I really like libgdx's (game framework) packer. Maybe a bit cumbersome to set up the framework just for the packer, though.

The packer works great. Read the libgdx texturepacker doc here, and see for yourself. My favourite feature is that is also saves a document with info about all the textures in the big spritesheet/atlas, so you can easily make a script that gets them for you. Libgdx also has this build in, so I can load/display any texture by it's original filename, even though it's in a big atlas. There also exists a GUI for the packer.

Excerpt from a pack-file with info about some textures:

ferdige1.png
format: RGBA8888
filter: Nearest,Nearest
repeat: none
mainmenu
  rotate: false
  xy: 2, 2
  size: 800, 480
  orig: 800, 480
  offset: 0, 0
  index: -1
plankeu3
  rotate: false
  xy: 804, 2
  size: 64, 384
  orig: 64, 384
  offset: 0, 0
  index: -1
levelSelect
  rotate: false
  xy: 2, 484
  size: 591, 373
  orig: 591, 373
  offset: 0, 0
  index: -1
plankeu2
  rotate: false
  xy: 870, 2
  size: 64, 256
  orig: 64, 256

I ended up using this Processing script. You can download Processing for free at Processing.org. All files need to be in the same folder, and have a filename ending in a 4 digit number.

ArrayList<PImage> images = new ArrayList

<PImage>();

void setup() {
  String folder = "file location ...";
  String file = "file prefix ...";
  String outfile = "output.png";
  int fileCount = 30;
  int cols = 7;
  int rows = 5;

  println("Loadgin...");
  for (int i = 1; i <= fileCount; i++) {
    String number = "" + i;
    if(number.length() == 1) number ="000" + number;
    else if(number.length() == 2) number = "00" + number;
    PImage img = loadImage(folder+file + number +".png");
    images.add(img);   
  }

  println("Starting...");
  PImage img = createImage(images.get(0).width * cols, images.get(0).height * rows, ARGB);
  for (int x = 0; x < images.get(0).width; x++) {
    for (int y = 0; y < images.get(0).height; y++) {
      for (int z = 0; z < images.size(); z++) {
        img.set(
          x+images.get(0).width* (z%cols),
          y +images.get(0).height * int(z/cols),
          images.get(z).get(x,y));
      }
    } 
  }
  println("Saving...");
  img.save(folder + outfile);
}

I use a Photoshop script to make spritesheets, see this article on my blog.

It can make old skool tile grids as well as texture atlases, and can export a custom text file containing image size and position info. It works on PC and Mac, it's open source and written to be extensible.

I don't know if I understood question correcttly but I know the software that operates with textures and makes animation, sprite sheets anf .gif animations. see http://www.spritetools.com/

The Compass framework has a sprite generation tool.
