Magic Bytes

The VDA image format is a legacy raster graphic specification originally developed by Truevision for use with their specialized video hardware. It served as an early variant of the Targa file structure, primarily utilized for high-resolution image capture and digital photo manipulation in professional broadcast environments. As an uncompressed or simple RLE-encoded bitmap format, it carries a low security risk and is now largely considered obsolete, having been superseded by the unified TGA standard.
