Convert PTIF to SGI

The PTIF (Pyramid Encoded TIFF) file format, developed by Image Magick, is a specialized variant of the TIFF image format designed to store multiple resolutions of the same image within a single file. This enables efficient zooming and panning in applications without losing image quality. PTIF files are commonly used in geospatial imaging, remote sensing, and medical imaging due to their ability to handle large, high-resolution images efficiently. The format was introduced to address the need for handling large image datasets more effectively in these fields.

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.
