Stykz can export all of the frames of your animation as a series of image files in PNG, JPEG or GIF format.
To export the a sequence of images, select File > Export Animation.... When the Export animation dialog box shows up, select from the Format dropdown menu:
If you choose Sequence of PNG Images, the frames will be exported as PNG images with the background color of each frame opaque. If you choose Sequence of Transparent PNG Images, the frames will be exported as PNG images with the background color of each frame transparent. The other two choices (Sequence of JPEG Images and Sequence of GIF Images) will cause each frame to be exported in the selected format.
NOTE: If you export the sequence of frames as GIF and you have not been using Web Colors, the colors of your exported images may be dithered or banded since the GIF format supports only 256 colors.
The last thing to do is give the sequence a name and click Save; each frame will be exported in the selected format, and they will be numbered starting with 1 (so if you entered "My Anim" as the sequence name, the first frame will be "My Anim1", the second "My Anim2", and so on).
NOTE: It is recommended that you create a folder beforehand to hold the exported image sequence.
