Introduction

We try to have screenshots on our website for all games that we support. The purpose of this page is to describe how new screenshots are to be made to ensure uniform overall quality. In particular, what scaler you should use, how files should be named etc.

For each game, we would like to have a small (say, between 2 and 5) number of screenshots which give users a good idea of what the game looks like to play. If the game is available in different languages or versions, it would also be nice to have a screenshot or two showing the differences of those versions. Take a look at our existing screenshots of The Secret of Monkey Island as an example.

How to make screenshots

Here are additional rules on how to make screenshots which were settled in the last couple of years: (Of course any suggestions are welcome!)

  • Check if this particular screenshot hasn't already been committed.
    • If there is no visual difference between an already submitted screenshot and your game version, don't submit it.
    • If you are submitting screenshots for non-English game, use only those which have visual difference (changed graphics) or have something written in that language.
  • ScummVM settings
    • Pick an interesting scene to take the screenshot of.
    • 320x200 games should be run with HQ2x (Ctrl+Alt+3) mode with aspect correction (Ctrl+Alt+a) mode on. I.e. it should be 640x480 image.
    • 640x480 games should be run without scaler.
    • On platforms which use the SDL backend (Win32 and *nix included) Alt+S creates a screenshot file called scummvmXXXXX.bmp inside the current directory.
    • Make sure your screenshot is 640x480 and was made with HQ2x scaler (if originally 320x200). Otherwise it won't be accepted.
    • If the game runs at a different resolution (such as 512x384, or 800x600), use the normal mode (no scaling) and make sure your screenshot is at the original resolution.
  • Screenshot file details.
    • Screenshots should not contain any window decorations.
    • The only supported file format is PNG with maximum compression.
    • Preferably run OptiPNG and advpng after that. Use default parameters for OptiPNG and -4 parameter for advpng for best results. If you don't, we'll have to do it later.
  • File name is gametarget[-platform][-lang]-X-full.png where:
      • gametarget is the game target name, see our compatibility page for the full list
      • platform is an optional parameter for cases when you submit non-PC game version screenshots
      • lang is an optional parameter when screenshot for non-English version
      • X is a sequental number.
    • Create a .txt file containing the file names followed by full game name and optionally provide the platform name and language in parenthesis. For example "Indiana Jones and the Fate of Atlantis (Amiga German)"
      • There is no need to provide titles for every file if they're all the same. Use your discretion.
  • If possible, use the mkthumb.sh script to produce thumbnail versions of your screenshots. If you don't have it or can't use it, then save in interlaced JPEG scaled down to 256 pixel width with quality 0.33 (or higher, watch for the compression artifacts). Optionally you can commit/submit only PNG and TXT and we will create the thumbnails for you.

How to make game icon

On screenshots page you may see the set of nice 'headshots' used for the games. If you are submitting screenshots for a new game, you may help with creating the icon too.

You will need GIMP 2.8.x for making the icon:

  1. Pick some distinguishable graphics from the game. In most cases, it is head of the main character or image of the main item in the game (such as the hourglass for Ween)
  2. Make its background transparent by carefully painting over all unneeded pixels
    • Magnify the image
    • If the background is not solid-colored, fill it with some color unused in the image. Acid green works well in most cases :)
    • With Select By Color tool select the background
    • Invert the selection
    • Add layer mask -> use selection as layer mask
    • Apply the layer mask
  3. Downscale image to 44x44 or less. Make sure that you're using bicubic scaling, and that features of the image are still recognizable
  4. Open file scummvm_badges.xcf
  5. Copy the badge and paste it into the new layer
  6. Select the layer with the badge
  7. Run Filters → Light and Shadow → Drop Shadow...
    • Offset X: 0
    • Offset Y: 2
    • Blur radius: 2
    • Color: black
    • Opacity: 64
    • Allow resizing: ticked
  8. Select the icon with the rectangle selection tool, up to 48x48 area. If the shadow is bigger, you will have to go back to step 3
  9. Edit → Copy Visible
  10. Edit → Paste as → New Image
  11. Make sure the canvas size is 58x58
  12. Save the result as PNG

You're done.

Now consider using optipng, advpng (see the previous section), but that is optional.

Below is the original instructions for Photoshop CS2+ for making the image shadow:

  1. Open file scummvm_badges.psd in Photoshop. You will need at least CS2 version
  2. Open your icon in Photoshop
  3. Copy/paste icon to scummvm_icons.psd file at some free place
  4. Open badges layer group, first badge, right click on it and select 'Copy layer styles'
  5. Switch to your pasted layer with game icon
  6. Paste layer styles to the game icon layer
  7. Select the icon with the selection tool, up to 44x44 area. If the shadow is bigger, you will have to go back to previous stage
  8. Click on Edit → 'Copy Merged' menu item
  9. File → New... (it will automatically have dimensions of the image in clipboard)
  10. Paste the image
  11. Save it as PNG

How to submit screenshots

  • If you have write access to our web source repository, you can commit it directly to the relevant directory.
  • Alternatively, you can submit it via our patch tracker.
    • There is a restriction on 250kb per file. There are 2 options you can do:
      1. Submit several files (you may add them one by one)
      2. Upload somewhere in one archive and provide link in the bugreport
  • If you didn't perform some actions with the screenshot file, for example if you didn't compress it or were unable to produce thumbnails, please mark your submission accordingly.
