Convert pct to vicar

What is the difference between .pct and .vicar?

Description: A PCT file is an image saved in the Macintosh PICT format, which was developed by Apple in 1984 for storing images using Apple QuickDraw technology. It contains image data in one of two formats, PICT 1, the original format that stores 8 colors, or PICT 2, a newer format that allows thousands of colors (24 and 32-bit images). PCT files support both raster and vector images.; The VICAR (Video Image Communication And Retrieval) Image file format is a flexible, image-processing and data format system used primarily by the planetary science community. Developed by NASA's Jet Propulsion Laboratory (JPL) for storing and managing digital images from space missions, VICAR files are designed to support a wide range of image types, including scientific and engineering data from various spacecraft instruments. This format is characterized by its ability to handle multi-dimensional arrays of data.
