Netpbm format - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Portable_anymap Netpbm format From Wikipedia, the free encyclopedia (Redirected from Portable anymap) The phrase Netpbm format commonly refers to any or all Portable pixmap of the members of a set of closely related graphics formats used and defined by the Netpbm project. The portable Filename .ppm, .pgm, .pbm, pixmap format (PPM), the portable graymap format extension .pnm (PGM) and the portable bitmap format (PBM) are image file formats designed to be easily exchanged between Internet image/x-portable- platforms. They are also sometimes referred to collectively media type pixmap, -graymap, [1] as the portable anymap format (PNM). -bitmap, -anymap all unofficial Developed Jef Poskanzer Contents by 1 History Type of Image file formats 2 File format description format 2.1 PBM example 2.2 PGM example 2.3 PPM example 3 16-bit extensions 4 See also 5 References 6 External links History The PBM format was invented by Jef Poskanzer in the 1980s as a format that allowed monochrome bitmaps to be transmitted within an email message as plain ASCII text, allowing it to survive any changes in text formatting. Poskanzer developed the first library of tools to handle the PBM format, Pbmplus, released in 1988. It mainly contained tools to convert between PBM and other graphics formats. By the end of 1988, Poskanzer had developed the PGM and PPM formats along with their associated tools and added them to Pbmplus. The final release of Pbmplus was December 10, 1991. In 1993, the Netpbm library was developed to replace the unmaintained Pbmplus. -

PFC LUCIA BERROCAL SAEZ.Pdf
El presente proyecto fin de carrera consiste en el diseño, desarrollo e implementación de una aplicación informática cuya función sea la identificación de distintos ficheros de imagen, audio y video y la interpretación y presentación de los metadatos asociados a los mismos. El software desarrollado, EXTRACTORDATOS_LBS, reconocerá el tipo de formato del fichero bajo estudio a partir del análisis de los bytes de identificación contenidos en la cabecera del archivo. En base a la información registrada en dicha cabecera, la aplicación interpretará el contenido de los metadatos asociados al fichero, mostrando por pantalla aquellos que resulten de interés para el análisis de los mismos. Previamente a la implementación del software se acomete el análisis teórico de los formatos de diversos archivos multimedia, recogidos en múltiples normas y recomendaciones. Tras esa identificación, se procede al desarrollo de la aplicación EXTRACTORDATOS_LBS , que informa de los parámetros de interés contenidos en las cabeceras de los archivos. El desarrollo se ilustra con los diagramas conceptuales asociados a la arquitectura del software implementado. De igual forma, se muestran las salidas por pantalla de una serie de ficheros de muestra, y se presenta el manual de usuario de la aplicación. La versión electrónica de este documento acompaña el ejecutable que permite el análisis de los archivos. This final project consists in the design, development and implementation of a computer application whose function is the identification of different image, audio and video files and the interpretation and presentation of their metadata. The software developed, EXTRACTORDATOS_LBS, will recognize the type of the file under study through the analysis of the identification bytes contained on the file’s header. -
TP1 Image File Manipulation
M1Mosig Introduction to Visual Computing TP1 Image File Manipulation The objective of this practical work is to implement basic image manipu- lation tools, e.g. read, write and convert. To this aim, and without loss of generality, the simple image file formats PBM (Portable Map) will be consid- ered. 1 "Portable Map" image file formats The netpbm file formats PBM, PGM and PPM are respectively: portable bitmap, portable grayscalemap and portable pixmap (also called PNM for portable anymap). They were originally designed in the early 80’s to ease image exchange between platforms. They offer a simple and pedagogical solution to develop image manipulation tools. In these formats, an image is a matrix of pixels where values represent the illumination in each pixel: white and black (PBM), grayscale (PGM) or 3 values RGB (PPM). Definition The PNM file content is as follows: 1. A ’magic number’ that identifies the file type. A pbm image’s magic number is the two characters ’P1’ (ASCII) or ’P4’ (binary). 2. Whitespace (blanks, TABs, CRs, LFs). 3. The width and height (separated with a whitespace) in pixels of the image, formatted as ASCII characters in decimal. 4. Only for PGM and PPM: The maximum intensity value between 0 and 255, again in ASCII decimal, followed by a whitespace. 5. Width × Height numbers. Those numbers are either decimal values coded in ASCII et separated by a whitespace for the formats P1, P2, P3, or directly binary values (usually 1 byte) in the case of P4, P5, P6. In the latter case, there is no whitespace between values. -

Image Formats
Image Formats Ioannis Rekleitis Many different file formats • JPEG/JFIF • Exif • JPEG 2000 • BMP • GIF • WebP • PNG • HDR raster formats • TIFF • HEIF • PPM, PGM, PBM, • BAT and PNM • BPG CSCE 590: Introduction to Image Processing https://en.wikipedia.org/wiki/Image_file_formats 2 Many different file formats • JPEG/JFIF (Joint Photographic Experts Group) is a lossy compression method; JPEG- compressed images are usually stored in the JFIF (JPEG File Interchange Format) >ile format. The JPEG/JFIF >ilename extension is JPG or JPEG. Nearly every digital camera can save images in the JPEG/JFIF format, which supports eight-bit grayscale images and 24-bit color images (eight bits each for red, green, and blue). JPEG applies lossy compression to images, which can result in a signi>icant reduction of the >ile size. Applications can determine the degree of compression to apply, and the amount of compression affects the visual quality of the result. When not too great, the compression does not noticeably affect or detract from the image's quality, but JPEG iles suffer generational degradation when repeatedly edited and saved. (JPEG also provides lossless image storage, but the lossless version is not widely supported.) • JPEG 2000 is a compression standard enabling both lossless and lossy storage. The compression methods used are different from the ones in standard JFIF/JPEG; they improve quality and compression ratios, but also require more computational power to process. JPEG 2000 also adds features that are missing in JPEG. It is not nearly as common as JPEG, but it is used currently in professional movie editing and distribution (some digital cinemas, for example, use JPEG 2000 for individual movie frames). -
