A .ppm extension file comprises of two parts which include the header and the image related data. The header, in turn, is distributed into three parts that are demarcated by line feeds. The first line comprises of the magical PPM identifier which can either be P3 for the ASCII version or P6 for the binary version, and the next line has the image's height and width displayed in ASCII characters and the last line indicates the maximum color value of the pixels. The image data formatting is dependent on the magical identifier, given in the first line of the header. Each pixel consists of 3 decimal values ranging from 0 to the specified maximum value written in ASCII characters. The 0 in the decimal values denotes that the color is not present or is turned off and the maximum value denotes that the color is at its maximum level. Conventionally the image data is stored in a left to right and top to bottom order with each pixel being stored as a byte. The usual RGB (Red ñ Green ñ Blue) order is followed to store the components.
JPEG files store meta information of the images. Meta information includes the technical details of the images such as color spaces, color profiles and the height and width of images. Adobe RGB and sRGB are examples of JPEG color profiles. JPEG file compression is mostly used in the compression of photographs and life-like paintings which involve a nice range of tone and ample variations in color. However, the JPEG file extension is not suitable for multiple edits and isn't reliable for compressing highly technical data other than visual content. Applications, where JPEG formats cannot be used, include scientific data, technical processes, and medical imaging functions. Each time an image undergoes JPEG compression, a drop in the resolution quality occurs. The best way to avoid this is to save the image in a lossless format and carry out its distribution by exporting it as a JPEG file. Lossless formats allow users not to lose out on image quality and restores all the pixel information when returned to its original size. This means you can revert the image back to its original size and quality, unlike lossy compression.
