Basic Drawing Types
Basically, there are three kinds of drawings in Rogue Wave® Views: lines, regions, and strings, with the attributes applied depending on the individual drawing needs and capabilities.
Lines
This category includes straight lines, curves and open-ended sets of connected straight lines or curves. Attributes are applied to lines as follows:
Color Straight lines or curves are drawn with the current foreground color.
Line Style The current line style (such as solid, dots or dashes) determines how the straight lines or curves are drawn.
Line Width An unsigned integer indicates the current line width.
Pattern Using monochrome (two-color), lines are drawn with the current pattern, but this is noticeable only with thick lines.
Color Pattern Using color, lines are drawn with the current color pattern. Here again, this effect is noticeable only for thick lines.
Regions
This term designates closed sets of connected lines or curves. Attributes are applied to regions as follows:
Color The closed curve around a region retains its original color; that is, the current foreground color.
Pattern Regions are filled with the current fill pattern or fill mask pattern.
Color Pattern Regions are filled with the current color pattern.
Fill Style This value determines if patterns are to be handled as masks, monochrome patterns or color patterns.
Fill Rule Determines the fill strategy for self-intersecting polygons. For details see
Fill Rule.
Arc Mode Determines how an arc is closed for filling. For details see
Arc Mode.
Strings
Attributes are applied to strings as follows:
Color The actual characters are printed with the foreground color.
Font The font in which the string is printed.
