Convert ORA to SIXEL

The ORA file extension stands for OpenRaster Image File, a format designed for the exchange of layered raster graphics between different software applications. Proposed in 2006 by developers from KDE and Krita, OpenRaster aims to provide an open alternative to proprietary formats like Adobe's PSD. The format encapsulates image layers, blending modes, and metadata within a ZIP archive containing XML and PNG files. Its primary use is to facilitate interoperability among various graphic editors, ensuring that complex image data can be shared and edited across different platforms.

The SIXEL, or "six pixels", is a bitmap graphics format created by Digital Equipment Corporation (DEC) for their terminals and printers. Initially designed for DEC dot matrix printers like the LA50, it enabled the efficient transfer of bitmap graphics using a series of ASCII characters. Each character represents a 6-pixel high row, making it suitable for 7-bit serial communication. This format was later adapted for modern terminal emulators, extending its utility beyond its original scope.
