Fill Area Attributes
FillOutlineType
FillOutlineType is an integer-value attribute that turns on or off the drawing of an outline around filled areas. Its value should be
FILL_TYPE_NONE (for outline off) or
FILL_TYPE_SOLID (for outline on). The default is to draw solid lines.
FillOutlineColor
FillOutlineColor is a
Color-valued attribute that determines the color used to outline the filled regions. The outline is drawn only if the attribute
FillOutlineType has the value
FILL_TYPE_SOLID. Its default value is
Color.black.
FillType
FillType is an integer-value attribute that turns on or off the drawing of the interior of filled areas. Its value should be
FillColor
FillColor is a
Color-valued attribute that determines the color used to fill a region with a solid color. Its default value is
Color.black.
Gradient
Gradient is a
Color array-valued attribute that fills a region with a gradient color. It does not have a default value.
The value of Gradient should be an array of four colors. These are the colors at the four corners of a square. In order they are: lower-left, lower-right, upper-right and upper-left.
If the lower-side colors are equal (
color[0] equals
color[1]) and the upper-side colors are equal (
color[2] equals
color[3]), then a vertical gradient is drawn.
If the left-side colors are equal (
color[0] equals
color[3]) and the right-side colors are equal (
color[1] equals
color[2]), then a horizontal gradient is drawn.
If the lower-right and upper-left colors (
color[1] and
color[3]) are null, then a diagonal gradient is drawn using the lower-left (
color[0]) and upper-right (
color[2]) colors.
If the lower-left and upper-right colors (
color[0] and
color[2]) are null, then a diagonal gradient is drawn using the lower-right (
color[1]) and upper-left (
color[3]) colors.
If none of the above patterns exist, then no gradient is drawn.
Vertical | | setGradient(Color.red, Color.red, Color.yellow, Color.yellow) |
Horizontal | | setGradient(Color.yellow, Color.red, Color.red, Color.yellow) |
Diagonal | | setGradient(Color.yellow, null, Color.red, null) |
Diagonal | | setGradient(null, Color.yellow, null, Color.red) |
