This document discusses different formats for images, text, and multimedia files. It explains that image files are either raster-based, made up of pixels that cannot be scaled without distortion, or vector-based, storing images as mathematical formulas that can be scaled. Common raster formats include JPEG, JPEG 2000 and TIFF, while common vector formats are DXF, EPS, CGM and shapefiles. Text files are often created in word processors and can be in proprietary, RTF, or PDF formats. Video and audio files contain moving images and sound, stored in proprietary formats like QuickTime, Windows Media, MPEG, AVI and WAV.

ONLINE FORMATS FOR IMAGES AND
TEXTS

2. Graphics files store an image and are
divided into two basic types:
>raster-based
>vector based files

3. →Stores the image as a
collection of pixels
→Cannot be scaled without
distortion
RASTER-BASED FILES

4. → Joint Photographic Experts Group (JPEG) – it supports wide range of colors
that makes it most popularly used on camera and scanners. This type is
commonly used in the Internet and photo sharing. Though, some details can
be affected when producing a smaller file size.
→ Joint Photographic Experts Group (JPEG2000) – it is an evolving format of the
JPEG developed with multiple compression techniques based on wavelet
technology.
→ Tagged Image File Format (TIFF) – it is the often format choice for high-quality
master image because its quality is as perfect as the original. File size can be
huge. It is commonly used when sending image to be included on printed
books, brochures, or magazines.

6. →Store an image as
mathematical formulas
VECTOR-BASED FILES

7. → Drawing Interchange Format (DXF) – commonly used in computer-
aided design software programs such as those used by engineer or
architects.
→ Encapsulated PostScript (EPS) – widely used in desktop publishing
software programs.
→ Computed Graphics Metafile (CGM) - widely used I many image
oriented software programs and offer a high degree of durability
→ Shapefiles (SHP) – uses vector coordinates to store non-topological
geometry and attribute information for features.
Common types of vector-based file formats

8. → Often created in word
processing software
programs
TEXT FILES

9. → Proprietary formats (Microsoft Word Files) – carry the extension of
the software in which they created
→ Rich Text Format (RTF) – supported by variety of applications and
saved with formatting instructions
→ Portable Document Format (PDF) – contains an image of the page,
including text and graphics. It is widely used for read-only file sharing.
Adobe Acrobat is the most common popular PDF file application.
Common types of text files formats

10. → Contains moving images and
sound data
→They are created and viewed in
proprietary software programs and
stored proprietary formats.
VIDEO AND AUDIO FILES

11. → QuickTime (.MOV)
→ Windows Media Video (.WMV)
→ Motion Picture Experts Group (.MPEG)(MP3)
→ Others such as .AVI and .WAV files
