1 Objective 1

2  Also known as raster images.  Made up of pixels in a grid.  Pixels: tiny dots of individual color that makes up what you see on your screen. Tiny dots come together in the form of the images you see.  When the image is enlarged, you can see each individual square dot of color.

3  Bitmap images are resolution dependent.  Resolution: # of pixels in an image.  Stated in:  Dpi (dots per image)  Ppi (pixels per image)  Its difficult to increase or decrease the size of an image without sacrificing a degree of image quality.  Reducing the image: throws away pixels.  Increasing the image: creates new pixels.

6  All scanned images are bitmap  Digital camera images are bitmap  Images can be converted from one format to another.

7  Made up of many individual, scalable objects.  Objects indentified by mathematical equations rather than pixels.  Always render the highest quality.  Objects consist of:  Lines  Curves  Shapes with editable attributes: such as color, fill, and outlines.

8  Changing the attributes of a vector object does not affect the object itself.  Freely change any # of object attributes without destroying the basic object.  Vector images are resolution independent.  Increase or decrease the size to any degree and your lines will remain crisp and sharp on screen and print.

9  Fonts are a type of vector object.  Vector images are not restricted to a rectangular shape like bitmap images.  Disadvantage of vector images: unsuitable for producing photo-realistic imagery.

10  AI (Adobe Illustrator)  CDR  CMX

11  Adobe Illustrator  CorelDRAW  Xara Xtreme  Serif DrawPlus

12  Image editors (pixel/bitmap based)  Illustration software (vector-based)

13  Most popular type of graphics software  Also known as paint applications  Allows you to create bitmap-based images from scratch using a variety of painting tools intended to mimic natural painting tools.  Most image editors include features for photo enhancement and retouching  Advantage: you can get a great deal of detail, as much as a photograph.  Disadvantage: confined by the pixel resolution of the image.

14  Because they consist of points and objects rather than pixels on a grid, they are free from the confines of pixel resolution.  Cannot contain the high level of detail as bitmapped images so they often have a cartoon-like appearance.  Most often used to create stylized, cartoon- like images, logos, maps, and other design elements that need to be output at any size.
