What is an OCI file?
Image created by openCanvas, a drawing program that records stroke events so that images can be automatically redrawn; stores a bitmap image created in the software and uses a proprietary format; often used for anime and other types of digital art.
NOTE: You can record the stroke events used to draw an OCI image and play them back in the software. openCanvas saved event files use the .OC3, .OC4, and .OC5 extensions, where the number is for the version of the software.
