| image Computer images can be created and viewed in many different formats The term formats refers to the idea that images are devised and stored by varying programs and methods (techniques). Virtually every image creation/manipulation program has a unique format, often incompatible with other image programs. There are many software packages available for image creation and/or manipulation see list on left and/or click here here here here There are two basic types of graphic images: Raster/bitmap images and Vector images. For more click here In the interest of consistency, on the Web there are only three image formats that are relatively safe for rendering images. These formats are used because: Most image capable browsers are configured to read image files based on these formats. Each of these formats compresses images, i.e. makes the images smaller, for faster Web page loading Each of the formats is relatively easy to display, and are commonly available in the most popular image creation programs. The three image formats are: JPEG for Joint Photographics Experts Group, which is named for the organization that created this image format. As the organization's name indicates, this is a good format for photographs. This method also does an excellent job of compressing files. It is not the best format for displaying drawings or illustrations. Often, files produced in this format will have a file name extension of jpg or jpeg, as in: filename.jpeg. Typically, this type of image format is pronounced "jay-peg." For those interested in the nitty-gritty details of the JPEG format, the official site is: www.jpeg.org/ GIF for Graphics Interchange Format, was initiated by the CompuServe online company. There are two versions of this format in common use: GIF87 and GIF89a. The GIF89a version is the most popular because with it images can be animated, among other features. This format tends to read colors in distinct patterns. As a result, this format is best used for drawings and other illustrations - which usually have distinct areas of contrasting colours. Typically, files produced in this format have a file name extension of gif. This type of image format is pronounced "giff" or "jiff." PNG for Portable Network Graphics is the newest of the graphics formats, and it is rapidly gaining widespread attention. It does an excellent job of compressing images, and is completely free and unhindered by proprietary concerns (the JPEG format is also not proprietary, but the GIF format is owned by the UNISYS Corp., which has exerted some ownership muscle in limiting GIF use.) Because the PNG format is free to use and more efficient, the W3C has been promoting it. However, there is one significant drawback to using the PNG format. Older browsers, such as any before Netscape® 4 or Internet Explorer® 4, can't view PNG images. The future seems to favor PNG, but for designers who have a large base of users with older browsers, it is not a viable image format. Usually images with the PNG format are named with a png extension, as in filename.png. Typically, the png image format is pronounced "ping." A good site for details on the PNG format is: www.cdrom.com/pub/png/ more ..... http://mylibrarian.com/lis/workpad13/workpad13.html type Of the many classes of type that are available (such as serif, sans-serif, slab, display, and script), the most commonly specified are serif and sans-serif (usually shortened to "sans") typefaces. Serif: What you see used in almost all newspapers, novels and textbooks is a serif typeface. Well-designed serif type is considered highly readable and is the oldest class of lettering used in print. Sans Serif: This class of type is without (sans) serifs. There are many styles from conservative to cutting-edge. Generally, sans faces are used for short to medium copy, headlines, footers, etc. Sans type is considered less readable than serif, and is thus rarely specified for lengthy texts (such as books). One rule of thumb in the use of type is that usually no more than two faces should be incorporated into a given piece. Additionally, using two of the same class typefaces (e.g., two sans faces) in the same layout typically does not work. In many cases, a combination of one serif and one sans face is used…one for the copy and the other for headlines and other special uses). Of course, there are always exceptions to the rule when the client's content calls for it. The way a piece of print looks is greatly influenced by the type face used. Differing type faces can create differing emotional messages for the viewer, for instance a large bold type could suggest authority. Good use of type is a skill that will give pleasure to the viewer when done well. more Text, the fundamental media ..... the most prevalent media and may be even the most important media is text. As we look at various Web sites, multimedia Web sites, we see excellent use of text and very poor use of text. What makes good use of text you might ask? Well, we are glad you did. We want to talk about some guidelines. First, the absolute major criteria of successful use of text is that it must be legible. For information about TYPOGRAPHY click here |
