Help with I.T homework?

Question

This is the question I have to do:
JPEG PNG and GIF images:
Will your word processor display them? What about your spread- sheet program? Can you find any other programs that will open these file types and any that won't?

Plz give as much info as possible. Thanx soo much!! XOX

Answer 1

JPEG/JPG

Short for Joint Photographic Experts Group, the original name of the committee that wrote the standard. JPG is one of the image file formats supported on the Web. JPG is a lossy compression technique that is designed to compress color and grayscale continuous-tone images. The information that is discarded in the compression is information that the human eye cannot detect. JPG images support 16 million colors and are best suited for photographs and complex graphics. The user typically has to compromise on either the quality of the image or the size of the file. JPG does not work well on line drawings, lettering or simple graphics because there is not a lot of the image that can be thrown out in the lossy process, so the image loses clarity and sharpness.



GIF

Short for Graphics Interchange Format, another of the graphics formats supported by the Web. Unlike JPG, the GIF format is a lossless compression technique and it supports only 256 colors. GIF is better than JPG for images with only a few distinct colors, such as line drawings, black and white images and small text that is only a few pixels high. With an animation editor, GIF images can be put together for animated images. GIF also supports transparency, where the background color can be set to transparent in order to let the color on the underlying Web page to show through. The compression algorithm used in the GIF format is owned by Unisys, and companies that use the algorithm are supposed to license the use from Unisys.*



PNG

Short for Portable Network Graphics, the third graphics standard supported by the Web (though not supported by all browsers). PNG was developed as a patent-free answer to the GIF format but is also an improvement on the GIF technique. An image in a lossless PNG file can be 5%-25% more compressed than a GIF file of the same image. PNG builds on the idea of transparency in GIF images and allows the control of the degree of transparency, known as opacity. Saving, restoring and re-saving a PNG image will not degrade its quality. PNG does not support animation like GIF does.

Hope this helped.

Answer 2

Yes Word and Excel will display these image formats but you have to go up to Insert, Picture, From file and navigate to where they are stored, You can also bring them in to Publisher and PowerPoint. If you want to work with them, i.e. edit in an imaging program then just File Open, and no problem.

Answer 3

Hi.



The majority of Word Processors will display them, as does your Spread-Sheet program.





Obviously other types of programs can show them, such as Image Viewers, Paint, GIMP, Paintshop Pro.



Itunes and Windows Media Player will show them in the format of album-art apart from GIF.



Good Luck

Answer 4

Microsoft Word and Excel as well as OpenOffice Writer and Calc will open and display all three. Lots of other programs can handle these formats, from iTunes (displays album artwork) to commercial apps like Lotus Notes.



Those that won't tend to be either old-fashioned or exclusively text-oriented, for example text editors like vi (or vim).
