Convert SVGZ to PGM

SVGZ, or Scalable Vector Graphics Compressed, is a file extension for compressed SVG files, utilizing the GZIP compression method. Introduced to optimize web performance, SVGZ retains the scalability and resolution independence of SVG while reducing file size, leading to faster load times and reduced bandwidth usage. This format is particularly valuable in web development, digital graphics, and applications requiring efficient transmission and rendering of vector graphics. SVGZ emerged as part of efforts to enhance web technologies, catering to the increasing demand for high-quality, scalable visuals in a more efficient manner.

The Portable Graymap (PGM) file extension, originating in the late 1980s as part of the Netpbm project, stands for "Portable Gray Map". It serves as a simple, versatile format for grayscale images, enabling easy reading and writing by various programs. Due to its straightforward structure and plain text encoding, it's often used in academic and research settings where ease of parsing and accessibility are crucial. PGM files store grayscale images in a compact, efficient manner, making them an essential tool for image processing tasks.
