Convert ptiff to pnm

What is the difference between .ptiff and .pnm?

Description: Ptiff is a type of image file that is created by compressing a TIFF (Tagged Image File Format) image using a wavelet-based encoding, known as pyramidal encoding. This type of file can store both lossy and lossless compressed images and is often used for storing large-scale images such as aerial photographs or medical images.; The PNM (Portable Any Map Image) file format is a subset of the broader Netpbm format, designed for storing various types of digital images. It acts as an umbrella term for three specific types of grayscale, color, and black-and-white images, represented by PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap) formats respectively. PNM files are known for their simplicity and ease of conversion to other image formats.
