PNM Photo Editor with Mirror Effect Downloads
PNM (Portable Anymap Format) is a collection of exchangeable Netpbm image formats, including the portable pixmap format (PPM), the portable graymap format (PGM) and the portable bitmap format (PBM).
Mirror effect represents a digital filter that creates a reflected duplicate of an object. The reflected duplicate is identical to the object, but it's shown in a reversed position.
Within this collection you will find several applications that will allow you to open and edit PNM image files. Furthermore, all these programs also apply mirror effects to pictures.
