![]() When checked, the background of the images within the PSD is set to transparent. A layer for each animation frame will be created inside the PSD file. Spine can export Adobe Photoshop PSD image files. It can be very useful to export the current pose in the middle of an animation as layers in a PSD so you can more easily redraw attachment images for that pose. When checked, the background of the APNG is set to transparent. It is supported by most modern browsers and has much higher quality than GIF, but the file size is usually larger. APNG is a lossless animated image format that supports transparency, so no loss of quality will occur. See texture packing for more information. This is convenient but running the texture packer separately provides more control over the packing. When checked, the exported images are packed into a texture atlas. The number of frames per second for the PNG sequence. Higher compression produces smaller files but takes longer to export. PNG is a lossless image format that supports transparency, so no loss of quality will occur. ![]() 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. When unchecked, the last frame of each animation is omitted. When checked, the animation is looped continuously. The number of frames per second for the GIF animation. Higher quality produces better colors but takes longer to export. Translucent pixels are made opaque using the matte color. ![]() When unchecked, the specified color is used for the background of the GIF. When checked, completely transparent pixels will be transparent instead of the background color. The type of dispersion and how the alpha range is used can be chosen for the best results. Dither disperses transparency to prevent hard edges. The amount of dither to apply to the GIF transparency. Dither disperses the colors to prevent hard edges in gradients.Īlpha values below this value are treated as 0. The amount of dither to apply to the GIF colors. 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. GIF also doesn't support translucency, so pixels can only be either opaque or transparent. GIF is an image format with only 256 colors, so some loss of quality may occur. Spine can export animated GIFs, making it easy to share animations on the internet. This data is used if the binary data is imported back into Spine. When checked, additional data is included in the binary data that is not usually needed at runtime. The binary files will use this file extension. The name of the file will use the name of the skeleton. However, it is not human readable and it is not easy to write tools to parse and manipulate the data.Ī binary file will be created in this folder for each skeleton in your project. See packing during data export for more information.īinary data is much smaller than JSON and it is very fast to parse at runtime. When checked, a texture atlas is packed during the data export. When checked, Spine will show any warning messages after exporting. When checked, animation clean up is performed for the exported data. This data is used if the JSON data is imported back into Spine. When checked, additional data is included in the JSON data that is not usually needed at runtime. See recovering work for more information. In many cases this is not possible, data will be lost, and warnings will be shown.Įxporting to older versions is intended only as a last resort to partially recover work when a project was accidentally saved with a newer version of Spine. If an older JSON version is chosen, Spine attempts to write data compatible with that older version of the Spine Runtimes. When checked, the JSON is formatted to be more easily read by humans. This format requires a lenient JSON parser, such as the one in libgdx.
