Convert SGI to VDA

The SGI file extension stands for Silicon Graphics Image, a raster graphics file format developed by Silicon Graphics Inc. primarily for their IRIS workstations. This format, originating in the late 1980s, supports uncompressed and RLE-compressed data with up to 48-bit color (16 bits per channel for RGB) and an alpha channel. SGI files are widely utilized in 3D graphics, visualization, and high-end imaging due to their ability to store high-quality images and intricate details, making them an essential asset in professional graphics and animation industries.

The VDA file extension, associated with Truevision Advanced Raster Graphics Adapter (TARGA), is a raster graphics file format developed by Truevision Inc. It was designed for high-color and true-color display on IBM-compatible PCs, supporting resolutions matching NTSC and PAL video formats. VDA files are used for digital photos, textures, and video editing, offering various color depths (8 to 32 bits) and alpha channel transparency. The format includes both lossless and lossy compression options, ensuring high-quality image preservation.
