PPM

Portable Pixmap Image File

The .ppm file extension is used for Portable PixMap format files and is intended to be an intermediate format that can be used in the development and conversion of other file formats. This format was specifically designed so that it could easily be exchanged between various platforms. It is very simple but not very storage efficient. Before the PPM format was introduced, Jef Poskanzer invented the PBM format in the year 1980 for transmission of monochrome bitmaps as ASCII text in email messages. He also developed a tool library for easy conversion of the PBM files to other graphical formats and vice versa. This library was called Pbmplus and was released in 1988. Later Poskanzer developed the PPM format along with the PGM format and the requisite tools that were added to Pbmplus.
ICO

Icon File

The .ICO filename extension refers to the ICON image file format originally developed by Microsoft. The extension is used to represent computer icon images of varying sizes designed for the operating system Microsoft Windows. Its use today has extended to developing icons for programs designed using the Microsoft developer's suite Visual Studio and other applications. Similar to other device independent bitmap file formats, the ICON file format is also in the raster graphics class of image formats where each individual pixel is part of an orthogonal dot matrix data structure with support for a limited palette of color information. As a resource file, the .ico file format has its strength in contextual use. This allows for multiple icon images of different color depth or size to be stored within the resource file and used when appropriate.

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.
