Convert FTS to PPM

The Flexible Image Transport System (FTS) file extension, is predominantly utilized for the storage, transmission, and manipulation of scientific and astronomical data. Developed by NASA in the late 1970s, this standardized format facilitates data interchange among the astronomical community. FTS is highly extensible, supporting various data types such as images, tables, and multidimensional arrays. Its widespread adoption stems from its capability to encapsulate metadata efficiently, enabling accurate and effective exchange of complex datasets among researchers and institutions.

The Portable Pixmap (PPM) file extension, an image format within the Netpbm family, stores simple, uncompressed images. Introduced in the late 1980s, PPM supports RGB color and grayscale images, making it suitable for basic image processing and conversion tasks. Its plain text encoding simplifies debugging and data manipulation, although its lack of compression results in larger file sizes compared to modern formats. As such, PPM finds limited use in contemporary applications, mainly in educational and experimental settings where ease of implementation and readability are prioritized.
