A PFM (Portable Float Map) file is a type of raster image file format used to store grayscale or color bitmap images with high precision. Unlike many other image formats, PFM files store pixel values as floating-point numbers, allowing for a wide range of values between 0 and 1 or -1 and 1 for each pixel. This high precision makes PFM files suitable for tasks like high dynamic range (HDR) imaging, where pixel values may need to represent a wide range of luminance or color data. PFM files are commonly used in computer graphics and image processing applications.

PFM files consist of a header section and an image data section. The header contains information about the image, such as its width, height, and whether it is in color or grayscale. The image data is stored as a sequence of floating-point values, with each value representing the intensity or color of a pixel. PFM files are known for their simplicity and ease of use, as they do not use complex compression or encoding schemes. This simplicity makes them a preferred choice for certain types of image manipulation tasks.

One of the key advantages of PFM files is their ability to accurately represent high dynamic range images, which contain a wide range of brightness levels. Because PFM files can store floating-point pixel values, they can faithfully capture the subtle variations in luminance or color that are often present in HDR images. This makes PFM files valuable in industries such as computer graphics, visual effects, and photography, where precise image data is crucial for achieving realistic and visually appealing results.
