Descripción | BMP File Format as been widely used on Windows platform. Although
it supports data compression and alpha channels, these features
were not widely used as it was not supported by all image editors. | GIF is a bitmap image format that allows a lossless compression by
reducing the image to 256 distinct colors. It has been replaced by
PNG after fear over patent issues. It is still widely used for
animation as it's the only format that supports animation and that
is widely supported by browsers. | JPEG is the most common image format used by digital cameras, it is
the most common format for storing and transmitting photographic
images on the World Wide Web. | PNG was created to improve GIF image-file format. Removing patent
license issues at that time; and removing 256 colors limitation. | RAW relates to several image file formats since each camera
manufacturer has one or several formats (depending on equipments).
These files contains the data acquired by sensors almost
unprocessed. | TIFF is a file format for storing images losslessly. It is widely
supported by image-manipulation applications, by scanning, faxing,
word processing, optical character recognition and other
applications. | JPEG 2000 is an enhancement of the JPEG standard. It supports
transparency, is able to store lossless data. It is also having a
better compression level. As it is unsupported by several browsers,
it has not been widely used on the Internet. | WebP is an image file format developed by Google, and supposed to
be a new open standard for lossily compressed true color graphics.
It's a direct competitor to JPEG. | SVG is an XML based file format. It allows to create vector
graphics with animation and interaction support. It can be edited
with any text editor. | EPS is a file extension for a graphics file format used in
vector-based images in Adobe Illustrator. EPS stands for
Encapsulated PostScript. An EPS file can contain text as well as
graphics. | PCT is a graphics file format introduced on the original Apple
Macintosh computer as its standard metafile format. It allows the
interchange of graphics (both bitmapped and vector), and some
limited text support, between Mac applications, and was the native
graphics format of QuickDraw. | PCX, standing for PiCture eXchange, was the native file format for
PC Paintbrush and became one of the first widely accepted DOS
imaging standards, although it has since been succeeded by more
sophisticated image formats. | PDF is a file format used to present documents in a manner
independent of application software, hardware, and operating
systems. Each PDF file encapsulates a complete description of a
fixed-layout flat document, including the text, fonts, graphics,
and other information needed to display it. | PSD is the default image file format used by Adobe Photoshop. It
supports layers and transparency. | TGA format is used widely in paint, graphics, and imaging
applications that require the storage of image data containing up
to 32 bits per pixel. TGA has also become popular in the world of
still-video editing. | WMF is an image file format intended to be portable between
applications and may contain both vector graphics and bitmap
components. It acts in a similar manner to SVG files. |

Desventajas | Large file size | Limited to 256 colors (8-bit per pixel). Only binary transparency. | Lossy compression
Not great for text, simple graphics, or illustrations | Lossless only. Poor compression for photographic images. | Large file size | Large file size
Not great for web graphics
Minor software compatibility issues | Processor intensive | Limited to 8-bit. Lossy forces 4:2:0 tv-range YCbCr. | Security issues; can contain executable code (javascript) and
non-embedded (URI) resources, so essentially requires a browser for
proper viewing. Not intended for print. | May lose control of advanced vector editing features | Fonts may be represented incorrectly when moved
cross-platform
QuickTime must be installed to view some PICT files correctly | Large file format
PC compatible only and older PCX versions only support 256 colours. | Longer browser loading times
Non-editable content
Not great for complex graphics printing
Not really useful as a graphic image | | Lacks a superior compression scheme | Not good for exporting or pasting bar graphs with fill patterns to
PowerPoint
Support is limited |
