Working With Graphics

Two Types of 2D Graphics Bitmap Bitmap Vector Vector

Bitmap A computer graphic file that contains dot-by-dot representations of the original graphic image A computer graphic file that contains dot-by-dot representations of the original graphic image –Basically, it’s an image made up of pixels When you try and stretch a bitmap image, it becomes pixilated When you try and stretch a bitmap image, it becomes pixilated

Bitmap Bitmapped images are also referred to as Raster Images Raster Images are often created with a camera or scanner. Raster Images are often created with a camera or scanner.

Vector Defined by mathematical equations instead of pixels, so they always have a high quality. Defined by mathematical equations instead of pixels, so they always have a high quality. No matter how you stretch vector images, they won’t pixilate No matter how you stretch vector images, they won’t pixilate Most clipart graphics are vector images and they are Most clipart graphics are vector images and they are resolution independent resolution independent Not useable for realistic images Not useable for realistic images –Too cartoon-like

Resolution Refers to the number of pixels in an image Refers to the number of pixels in an image –Usually stated as dpi (dots per inch) or ppi (pixels per inch) The higher the resolution, the more pixels will be in your image, the clearer your image will be The higher the resolution, the more pixels will be in your image, the clearer your image will be

Editing Images Crop Crop –Trim a graphic image

Editing Images Handle Handle –A small square that appears around graphics. –Used to change the size or shape of the object Graphic shapes contain 8 handles around an image Graphic shapes contain 8 handles around an image Bouncing Box Bouncing Box –Lines with handles around the image when it is selected

Editing Images Standoff Standoff –The distance within which text is kept away from a graphic Text wrap Text wrap Also called the offset Also called the offset This image has a text wrap so no text comes in contact with it This image has a text wrap so no text comes in contact with it

Editing Images Proportion Proportion –Sizing elements in relationship to their relative size –By holding down the shift key, you can keep the images proportions the same

Creating Documents Standard/Letter page size Standard/Letter page size –Default 8 ½” X 11” Legal size Legal size –8 ½” X 14” Tabloid size Tabloid size –11” X 17” Custom size Custom size –Anything else
