Convert vda to sixel

What is the difference between .vda and .sixel?

Description: The VDA file format, short for Targa Bitmap Image File, is a variant of the TGA file format (Truevision Advanced Raster Graphics Adapter) used for storing digital images. Developed by Truevision Inc., VDA files are raster graphics files that support various color depths, ranging from 1 to 32 bits per pixel, which includes support for alpha channels and compression. This format is designed to be highly flexible and is capable of storing high-quality images used in video editing and animations.; Created by Digital Equipment Corporation (DEC), SIXEL is a bitmap image format in an escaped sequence (seen as six pixels high and one pixel wide). You have to convert it into a more accessible format if you don’t have a DEC terminal to view it.
