List of file types

Image file formats

￿

Bitmap (.bmp). Often a good choice because Windows itself and

 

most Windows programs accept the .bmp file type.

￿

FlashPix (.fpx). A FlashPix file contains a complete image plus

 

several lower resolution copies of that image. The advantage of the

 

FlashPix file format over other file formats is that a program can

 

automatically select the best resolution for a particular job to make

 

editing and using images faster and easier. Cannot be used with

 

256-color output types.

￿

GIF (.gif). GIF is a compressed file format suitable for an image

 

that will be used on the Web or on multiple platforms. You can save

 

your GIF file as an interlaced GIF. Cannot be used with True Color

 

output type.

￿

JPEG (.jpg). JPEG is a compressed file format for images. Its

 

strengths are small file sizes and speed. The trade-off for these

 

advantages, though, is reduced image quality. Because each time

 

an image is compressed with JPEG it loses a little of the image

 

data, avoid compressing a file with JPEG more than once. JPEG is

 

an appropriate file format for an image that will be used on the Web

 

or on multiple platforms.

 

You can save your JPEG file as a progressive JPEG. When used

 

on a Web page, a progressive JPEG is initially sent as just every

 

other line, with the remaining lines sent immediately after. This

 

allows a (somewhat blurry) image to display sooner. Most people

 

prefer this. JPEG can be used only with True Color and Grayscale

 

output types.

￿

PNG (.png). A compressed image file format that might replace

 

GIF. Like GIF, PNG uses non-lossy compression, which means all

 

the visual data is saved and restored when the file is

 

decompressed. Unlike GIF, PNG can be used with the True Color

 

output type, as well as grayscale ones.

￿

TIFF (.tif). Usually created by scanners, TIFF files are widely

 

 

accepted by programs that work with photographs and other

 

 

images. A TIFF file is a bitmapped graphic (also called a raster

 

graphic) and can be any resolution. TIFF image files can be used

 

on multiple platforms.

 

￿

TIFF compressed (.tif). TIFF compressed files for images are

 

 

smaller than standard TIFF files.

 

￿

PCX image (.pcx). The PCX file format is for images used in

 

 

Windows programs such as PC Paintbrush and Paint.

 

￿

Windows Metafile (.wmf). The Microsoft Windows Metafile file

 

 

format is used for scalable (vector) images in Windows programs.

 

It is only available for images using the Black & White Scalable

 

(vector) output type.

 

Text or text-and-image file formats

 

￿

HTML (.htm). HTML is useful for text and graphics that will be

 

 

viewed on the World Wide Web. When this format is selected for a

 

scanned image containing both text and images, the text is

 

 

converted to editable text and is saved as HTML, and the graphics

 

are saved as GIF or JPEG files.

 

￿

PDF (.pdf). PDF is a format useful for text, photos, and drawings.

 

Use Adobe Acrobat Reader to view .pdf files. If no changes need to

 

be made to the file, this file type is useful for sharing (as through

 

e-mail) and filing because of its generally small file size.

 

￿

Rich Text (.rtf). The .rtf format can be used with a page that

 

 

contains text or text and pictures. The formatting of text in an .rtf file

 

can usually be retained and then interpreted by other programs.

￿

Text (.txt). Use .txt file format for saving only the text in the

 

 

selection area and when you are using the Editable Text (OCR)

 

output type. Text will be editable, unformatted, ASCII text.
