1. Identify and explain the two major font technologies for computer text. Give an advantage and disadvantage of each technology.
Ans: The two major technologies are bitmapped and outline fonts. Bitmapped fonts are displayed as a grid of pixels. Each letter is described by a series of bits to define the pixels making up the letter. Bitmapped fonts require large amounts of memory if there is a wide range of color and letter styles. Different bitmaps must be designed for each size of text to use. They have the advantage of giving a developer precise control over the appearance of each character since they can be edited at the pixel level. Outline fonts store a set of instructions to draw the letter rather than a mapping of pixels. Outline fonts take less memory since they are stored as a command and they can be scaled easily without distortion of the letter shape. Outline fonts do not allow a developer to edit the look of the letter at the pixel level so there is limited creativity in the overall design of the character.
2. Identify and explain the four methods of incorporating text into a multimedia application.
Ans: The four methods of adding text to a multimedia application are direct entry, copy and paste, file import, and using optical character recognition. Most authoring applications provide a means to type the desired text into a box or field on the screen. Graphics text can often just be typed on the screen with a graphics text tool. For pre-existing text blocks three other options exist. The developer can copy the text from another digital text file and paste it into the application. The text may also be imported into the authoring application if it exists in a compatible file format. Finally, the text can be scanned from a printed source and converted to a text file using OCR software. The scanned text may have errors so it is best to spell check and proof read any text that is converted from print using OCR.
