Question 3 Explanation:
Line Attributes: Basic attributes of a straight line segment are its type, its width, and its color. In some graphics packages, lines can also be displayed using selected pen or brush options.
AREA-FILL ATTRIBUTES: Basic attributes of an area-fill are
Fill Styles: Areas are displayed with three basic fill styles: hollow with a color border, filled with a solid color, or Wed with a specified pattern or design.
Pattern Fill
Soft Fill: the linear soft-fill algorithm repaints an area that was originally painted by merging a foreground color F with a single background color 8, where F + B.The current RGB color P of each pixel within the area to be refilled is some linear combination of F and B:
P = tF + (1- t)B
where the “transparency” factor t has a value between 0 and 1 for each pixel. RGB component of the colors
P = (PR, PC, PR), F = (FR, Fc, FR), B = (BR, Bc, BB)
Text Attributes: Following are the text attributes:
Font : is the choice of font (or typeface), which is a set of characters with a particular design style such as New York, Courier, Helvetica, London, ‘Times Roman, and various special symbol groups.
Font size
Font colour
Marker Attributes: A marker symbol is a single character that can be displayed in different colors and in different sizes. We select a particular character to be the marker symbol with
setMarkerType (int)
Hence Marker attributes are type, size and color.
