Export

Spine can export a single image, sequence of images, video, and JSON or binary data.

To open the Export dialog, press ctrl+E (cmd+E on Mac) or click the Spine logo in the upper left of Spine and choose Export from the menu.

JSON

Spine can export all of the skeleton data as JSON. This data can then be loaded by a Spine runtime and displayed in your applications just as it is in Spine

JSON has some advantages over binary. Most changes to the Spine export format don't invalidate previously exported JSON data. JSON is also human readable and easy for code to parse. The downside is that JSON data is larger and parsing the data is slower.

See JSON Format for detailed information about the JSON data that is exported.

  • Output folder A JSON file will be created in this folder for each skeleton in your project. The name of the file will use the name of the skeleton.
  • Extension The JSON files will use this file extension.
  • Format Spine can optionally write in JSON-like formats that are slightly smaller, easier to read, and easier to edit.
  • JSON Standard JSON.
  • JavaScript Like JSON, but names are only quoted if necessary. The output is valid JavaScript.
  • Minimal Like JSON, but names and values are only quoted if they don't contain rnt or space and don't begin with /{}[]:,". Additionally, names cannot contain : and values cannot contain }],. This format requires a lenient JSON parser, such as the one in libgdx.
  • Pretty print When checked, the JSON is formatted nicely so it is more easily ready by humans. This makes the file slightly larger.
  • Nonessential data When checked, additional data is included in the JSON that is not needed to rendering the skeletons. This makes the file slightly larger. This data is needed if the JSON will be imported back into Spine. See Import for more information.
  • Animation clean up When checked, animation cleaned up is performed before export. This does not modify the project file.
  • Warnings When checked, Spine will show any warning messages after exporting.
  • Pack When checked, it packs either only the images used by attachments or each skeleton's images folder into a texture atlas. This is convenient but running the texture packer separately provides more control over the packing. See Texture Packing for more information.

Binary

Spine can export all of the skeleton data as binary. This data can then be loaded by a Spine runtime and displayed in your applications just as it is in Spine.

Binary has some advantages over JSON. It is smaller and fast to parse by code, but it is not human readable. The downside is that any changes to the Spine export format will invalidate any previously exported binary data, which then needs to be exported again.

See Binary Format for detailed information about the binary data that is exported.

  • Output folder A binary file will be created in this folder for each skeleton in your project. The name of the file will use the name of the skeleton.
  • Extension The binary files will use this file extension.
  • Nonessential data When checked, additional data is included in the binary data that is not needed to rendering the skeletons. This makes the file slightly larger. This data is needed if the binary data will be imported back into Spine. See Import for more information.
  • Animation clean up When checked, animation cleaned up is performed before export. This does not modify the project file.
  • Warnings When checked, Spine will show any warning messages after exporting.
  • Pack When checked, it packs either only the images used by attachments or each skeleton's images folder into a texture atlas. This is convenient but running the texture packer separately provides more control over the packing. See Texture Packing for more information.

GIF

Spine can export an animated GIF, making it easy to share on the Internet. GIF is an image format with only 256 colors and doesn't support translucency, so some loss of quality may occur. Spine's GIF export is very sophisticated and produces the highest quality GIFs that are possible, but does not prioritize for a small file size.

  • Export type The type of export to perform.
    • Animations The current animation, all the animations, or an animation from the dropdown menu are exported as an animated GIF.
    • Current pose The current skeleton pose is exported as a static GIF.
    • Skins The current skin, all the skins, or all plus the version where no skin is active are exported.
  • Defaults Resets all the settings to the defaults.
  • Preview Opens the preview panel for the export window.
  • Output type Either creates a single file or a file per frame.
  • Output file The GIF file to write.
  • Animation repeat The number of times to play each animation.
  • Pause after The number of seconds to pause after playing each animation.
  • Bones If checked, skeleton bones will be rendered.
  • Images If checked, skeleton images will be rendered.
  • Others If checked, other skeleton elements such as paths will be rendered.
  • Linear filtering If checked, Linear filtering will be applied to the image.
  • Multisample AA The depth of multisample anti-aliasing to apply to the image.
  • Viewport crop If checked, it enables cropping the image to a custom dimension. The amount of X and Y offset of the cropping area can be specified in the first two boxes. The size of the area can be specified in pixels in the last two boxes. Enabling this setting also allows resizing the box in the export preview by dragging the orange corners.
  • Size The type of Resizing to perform.
    • Scale The relative scale of the image as a percentage.
    • Fit When selected, the output image will fit within the specified pixel values.
      • Enlarge If checked, and the content is smaller than the specified size, the content of the image is proportionally stretched until one of the sides matches the specified size.
      • Pad If checked, additional space is added to the image to match the specified size.
  • Range If checked, only the specified frames will be exported.
  • Colors The maximum number of colors in the GIF.
  • Color dither The amount of dither to apply to the GIF colors. Dither disperses the colors to prevent hard edges in gradients.
  • Alpha threshold Alpha values below this value are treated as 0.
  • Alpha dither The amount of dither to apply to the GIF transparency. Dither disperses transparency to prevent hard edges.
  • Background The background color to use.
    • Transparent When checked, completely transparent pixels will be transparent instead of the background color. When unchecked, the specified color is used for the background of the GIF.
    • Matte Translucent pixels are made opaque using the matte color.
  • Quality Higher quality produces better colors but takes longer to export.
  • FPS The number of frames per second for the GIF animation. 50 generally provides the best results.
  • Forever When checked, the animation is looped continuously.
  • Include last frame When unchecked, the last frame of each animation is omitted. Unchecking this is useful for looping animations where the first and last frame are identical -- the same frame would be exported twice when this setting is checked.

PNG

Spine can export PNG images. PNG is a lossless image format that supports transparency, so no loss of quality will occur.

  • Export type The type of export to perform.
    • Animations The current animation, all the animations, or an animation from the dropdown menu are exported as a PNG sequence.

  • Range If checked, only the specified frames will be exported.
  • Background The background color to use.
    • Transparent When checked, the background of the PNG is set to transparent.
  • Compression Higher compression produces smaller files but takes longer to export.
  • FPS The number of frames per second for the PNG sequence.

MOV

Spine can export a QuickTime MOV video file of the current animation. The RAW and PNG encodings for MOV files support transparency, which can be a convenient way to bring Spine animation into other software using a single file.

Please note that video playback support varies for different resolutions and encodings. Some video playback software is unable to play some video files, while other software can play them just fine.

  • Include last frame When unchecked, the last frame of each animation is omitted. Unchecking this is useful for looping animations where the first and last frame are identical -- the same frame would be exported twice when this setting is checked.

Preview panel

The preview panel allows to preview the result of an export. When active, it will reflect the changes made in the export settings.

A white box around shows the border of the rendered animation.

When Crop is enabled, a box with orange corners allows the user to resize the output by clicking on one of the orange corners, or move the box by clicking inside it, then dragging the box.

The dimension expressed in pixels, and estimated size of the export are displayed at the bottom.

The slider and arrows allow to scrub through the render animation frames, while the number indicates the current frame. These frames may not correspond to the ones in the dopesheet, as they depend on the FPS set in the export settings.

Disabling export

It is possible to mark skeletons, attachments, and skins to be exclude from exports. For example, this is useful to use a skeleton or attachment as a background or animation reference.

To do so, select a skeleton, skin, or attachment in the tree, then uncheck Export in the properties at the bottom of the tre.

If an attachment is not exported but it is keyed in animations, the keys will not be exported. If a mesh is not exported, any linked meshes will also not be exported.

Command line

Export and texture packing can be run from the command line, for use with scripts and build servers. When run in this way, Spine starts, does one or more exports or texture packings, then exits.

Prerequisites

Both Spine and the Spine launcher must be version 2.1.00 or higher to perform command line export. Also, if some export parameters are not accepted, it could be those parameters were added in a later version. To update the Spine launcher, use the Spine license link which was emailed when Spine was purchased to download and reinstall Spine.

JSON and binary data export, import, texture packing, and texture unpacking can be performed on a headless machine. To export images or video, an OS windowing system and OpenGL are required.

The output folder is created if it does not exist. Multiple export, import, texture packing, etc can be specified, as seen in the examples. If a command fails, Spine returns a non-zero error code.

Project export

For JSON, binary, image, and video export, the input and output paths are optional. If specified, they override the input and/or output paths specified in the export settings JSON file. The input path is a path to a project, JSON, or binary file. The output path may be a file or folder, depending on the export settings. The export settings JSON file is created using Spine by clicking on the Save button at the bottom of the Export dialog.

If the "clean up" parameter is specified, animation cleaned up is performed before export. This does not modify the project file.

Project import

For project import, the input path is a project, JSON, or binary file. Alternatively, it can be a folder containing .spine, .json, or .skel files. The output path is a project file. If a scale is specified, the project's skeletons are scaled before they are imported.

If a project is imported into another project, all skeletons are imported. If a skeleton name is specified and only one skeleton is imported, then the skeleton is renamed. If multiple skeletons are imported, the skeleton name is ignored and the skeletons keep their existing names.

If a JSON or binary file is imported into a project and a skeleton name is specified, then the skeleton is renamed. If a skeleton name is not specified, the skeleton is named using the JSON or binary file name without the extension.

Animation clean up

For animation clean up, the input path is a project file or folder containing .spine files. Animation clean up is performed for every skeleton and animation in the project and the project file is updated.

Texture packing

For texture packing, the input and output paths are folder paths. The --pack or -p parameter is either the texture atlas name to use when writing output files or a path to a pack settings JSON file. The pack settings JSON file is created using Spine by clicking on the Save button at the bottom of the Texture Packer Settings dialog. The name of the JSON file without the file extension is used as the texture atlas name.

When texture packing occurs, the settings from the specified pack settings JSON file are used. If a texture atlas name is specified instead, then the default settings are used. These settings are overridden by settings defined in any pack.json files found in the input folders. See the Spine texture packer JSON Configuration for more information.

One or more project files can be specified using --project or -j. When whitespace stripping is enabled, the texture packer looks in these projects for each image file. Any meshes found to use the image file are taken into account so whitespace stripping will not remove blank pixels used by the meshes. When --project or -j is specified, the currentProject texture packer setting is ignored, as if it were set to true.

Texture unpacking

For texture unpacking, the input path is an atlas file and the output path is a folder where the unpacked images will be written.

Project information

For project information, the input path is a project file or folder containing .spine files. Information is output for each project file. This can useful to know what version of Spine a project was saved with, how many animations are in the project, and other information.

Windows

Spine for Windows comes with two executables: Spine.exe and Spine.com. The EXE file is a GUI application, it starts Spine without a console window and doesn't wait for Spine to exit. The COM file is a command line application, it directs Spine's output to a console window and waits for Spine to exit.

Either executable can be used for command line export, but generally the COM file is preferred. If the Spine installation folder is on the system path or is the current working directory, specifying Spine without an extension will always execute Spine.com. For example:

Spine -e C:\path\to\export.json

Mac

Command line export when using Spine for Mac is done by launching the Spine executable file directly rather than opening Spine.app. The executable is found inside Spine.app at Spine.app/Contents/MacOS/Spine. For example:

/Applications/Spine/Spine.app/Contents/MacOS/Spine -e /path/to/export.json

Linux

Command line export when using Spine for Linux is done by running the Spine.sh script. For example:

./Spine.sh -e /path/to/export.json
