Ideally you’ll be able to use your tweened and optimized Spriter animations directly in the game authoring system of your choice, but obviously this can’t always be the case.  Sometimes you’ll need to create animations for a game engine that can’t support Spriter files directly. Similarly, sometimes you might create an animation for things like explosions which end up using dozens of tweened, rotating and scaling images at once, but plastering your game-screen with lots of these explosions might adversly effect your frame-rate.  Therefore it would be better for your game if the explosion could be converted to just a sequence of full frame images (to reduce the need for all the seperate draws and tweening calculations). For these types of circumstances, Spriter lets you export finished animations as sequential images at any frame rate (number of frame images per second) you’d like. Here’s how: 1) Once your animation is finished, make sure that animation is selected in the Animations Palette and then from Spriter’s menu choose File/Export To PNG.

2) A file selector will appear, allowing you to designate the location and name for the images to be saved.  Navigate to or create the folder you’d like the images to be saved in and then type the name for the images and press enter or click on the save button.
3) The Export Keyframes To PNG Dialogue box will appear, giving you a plethora of options to choose from while exporting your animation as sequential images.  First, decide if you want to only export the keyframes themselves, if you’d like to export frames based on a specific number of frames per second, or if you’d lust like to tell Spriter how many frames total the export should create for the entire animation. You can also just tell Spriter to export an image per however many miliseconds you’d like.  These are the first 3 options in the palette.
4) Using the second part of the export dialogue you can decide how your animation will be trimmed. Most of the time, You’ll want to leave it at the default settings, as its sure to not accidentall clip (remove) parts of any of the frame.  But, if you want more specific controll, or specifically want to crop the animation, then you can use the settings in this part of the palette to specify exact cropping coordinates. Just click the grey rectangle that says “trim rect to animation” and the other options will appear.  Choosing any of them will reveal additional settings specific to that cropping option.
5) You can use the bottom section of the palette to decide at what scale you’d like to export your animation.  By default it will be set to 100 percent. (actual size).  Just use these settings to determine what size you’d like the animation exported to.  Once you’ve decide and you’ve made sure all the settings from the previous steps are correct, just click OK and the exporting will commence into the folder you had selected.
6) Notice the option checkbox called “batch export” at the top left of the export dialogue window.  If you check this option, you’ll be able to choose to export all or any number of specific animations all at once, all with identical settings.  This can save you tons of time and assure all animations are cropped (and trimmed) to the same exact dimensions etc.
