Working With Graphics

Created by Dianna Moore

Two Types of 2D Graphics

• Bitmap

• Vector

Bitmap• 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

Bitmap

Bitmapped images are also referred to as Raster Images

• 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.

• No matter how you stretch vector images, they won’t pixilate

• Most clipart graphics are vector images and they are

resolution independent• Not useable for realistic images

– Too cartoon-like

Resolution• 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

Editing Images• Crop

– Trim a graphic image

Editing Images• Handle

– A small square that appears around graphics.

– Used to change the size or shape of the object

• Graphic shapes contain8 handles around an image

• Bounding Box– Lines with handles

around the image when it is selected

Editing Images• Standoff

– The distance within which text is kept away from a graphic• Text wrap• Also called the

offset

• This image has a text wrap so no text comes in contact with it

Editing Images• Proportion

– Sizing elements in relationship to their relative size

– By holding down the shift key, you can keep the images proportions the same

Skewing

• Option that lets you distort objects such as text boxes, drawn or imported graphics, or groups for a special effect

Creating Documents• Standard/Letter page size

– Default 8 ½” X 11”• Legal size

– 8 ½” X 14”• Tabloid size

– 11” X 17”• Custom size

– Anything else

Creating Documents• Don’t crowd your page with graphics

Creating Documents• You should have ONE dominant

graphic• Vary the size and shape of graphics
