What is a .OC4 file?
The file extension .OC4 is associated with a type of file known as an openCanvas 4 Event File. This kind of file is specifically created by a drawing program called openCanvas. openCanvas is a software application designed for artists and illustrators to create digital drawings and paintings. One of the unique features of openCanvas is its ability to record and save the process of creating an artwork. This is where the .OC4 file comes into play.
An .OC4 file essentially captures and stores all the different drawing actions, such as brush strokes, that an artist makes while creating an image in openCanvas version 4. This includes every line drawn, every color chosen, and every eraser action, among other things. The purpose of saving these actions in an .OC4 file is so that they can be played back later within the software. By opening an .OC4 file in openCanvas, you can watch a replay of how the original drawing or painting was made, step by step. This can be very useful for learning techniques, sharing your drawing process with others, or reviewing your own work.
To open an .OC4 file, you need to have the openCanvas software, specifically version 4, since this file extension is designed for that version. However, it's worth noting that openCanvas has different versions, and each version has its own corresponding file extension for event files. For example, openCanvas version 3 uses .OC3 files, and version 5 uses .OC5 files for saving drawing events. This means that if you have a different version of openCanvas, you might not be able to open an .OC4 file unless the software supports backward compatibility with older file formats.
In summary, if you come across an .OC4 file and you're interested in seeing the drawing process it contains, you'll need to use the Portalgraphics openCanvas software, specifically version 4, to open and view the playback of the drawing events saved within the file.
