- Description
- The PPMA file format, also known as Portable Bitmap, is a plain text format used for representing bitmap images. This format is a part of the Netpbm suite, which includes various formats for portable grayscale, color, and bitmap images. PPMA files specifically store color images using ASCII text to describe the width, height, maximum color value, and the pixel values in terms of red, green, and blue components. It is designed for simplicity and ease of transfer between different computer systems, though the ASCII representation makes it less efficient in terms of file size compared to binary image formats.
- Image stored in the JPEG XR format, which was originally developed by Microsoft for Windows Media software; supports deep color images with 48-bit RGB; used for high-resolution professional image editing; also supports lossless and lossy compression.
