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
• FILL_TYPE_NONE for fill off.
• FILL_TYPE_SOLID for fill by a single, solid color. This is the default.
• FILL_TYPE_GRADIENT for fill by a color gradient.
• FILL_TYPE_PAINT for fill by a Paint object. This is usually a TexturePaint object.
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.
