Image Editing Tools for
Web Design and Development
August 24, 2013
Image editing involves methods of altering images, to both digital photographs and traditional photographs. Applications used to create interactive Web graphics are the primary tools designers use to alter images. Many image editing programs are also used to render or create computer art from scratch. Designers must consider the important elements of a digital tool when trying to choose one for a specific purpose.
One of the requirements for many of the tools designers use is having a procedure to allow the user to select part(s) of an image, and applying a change without affecting the rest of the image. Most graphics applications have several methods of accomplishing this; a marquee tool selects rectangular areas, a lasso tool enables a freehand trace of an area, and a magic wand tool selects objects or areas in the image by the closeness of its color or luminance. These are in addition to “more advanced abilities such as edge detection, masking, alpha compositing, and color and channel-based extraction” (Arms & Fleischhauer, 2003). Animating the border of a selected area in an image helps the user to differentiate the border from the image background.
Layers are another feature designers should consider when choosing an image editor, and fortunately, they are common to many graphics applications. Layers are stacked on top of each other, but each layer is capable of being positioned in a way that is altered and blended with the layers below it; this can be done without affecting any of the other layers. This work routine has become the norm for the majority of graphics applications available today because it enables extreme flexibility for the user and its ease of use.
Moving on, resizing, or scaling images is again, another important process designers use when editing; this means making them larger or smaller. Many images...
