Graphics software is used to create images or manipulate existing images on a computer. Most programs consist of two basic parts – a working area and a toolbox or panel. The working area contains the image and displays the changes as they are made, while the toolbox contains a range of functions such as cropping, text input, and brush tools. Some programs also support video or animation input, or optimize images to be exported in video applications.
Types Of Graphics Software
Kinds of Graphics Softwares include the following:
Vector illustration software
Vector illustration software uses mathematical equations to define each element in the image.
They allow small images to be resized without affecting image proportions or resolution.
They are used to create simple lines, shapes, and figures.
Their files are usually very small, since they do not have to define each pixel in the image.
Bitmap software
Bitmap software, also called raster software, assigns properties to every pixel in the image.
They work with fixed image sizes. Images can get blurry or lose quality when resized.
They are commonly used to edit imported images, such as photographs.
They make much larger files than vector programs because they contain data about each pixel.
Choosing Graphics Software (Buying Tips)
Image import: Choose a graphics software that imports images directly from sources other than the hard disk, such as digital cameras and memory cards. Look for one with quick import tool to speed up transfers from external sources.
File formats: Choose a graphics software that lets you save your work in a wide range of file formats. If you will use the image for web publishing, look for web-friendly formats like .jpeg and .gif. For print publications, look for large formats such as .tiff.
