Convert SCT to PPM

The Scitex Continuous Tone (SCT) file format, developed by Scitex, is used for high-end image processing and supports CMYK, RGB, and grayscale images. SCT files are uncompressed, ensuring high image quality, and are typically used with Scitex graphics processors and image editing software. This format was designed to maintain the integrity of large, detailed images used in professional graphics workflows.

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.
