+ <gradientpaint> +

+The gradientpaint tag provides a way to fill a shape with a linear +color gradient pattern. If Point P1 with Color C1 and Point P2 with +Color C2 are specified in user space, the Color on the P1, P2 +connecting line is proportionally changed from C1 to C2. Any point +P not on the extended P1, P2 connecting line has the color of the +point P' that is the perpendicular projection of P on the extended P1, +P2 connecting line. Points on the extended line outside of the P1, +P2 segment can be colored in one of two ways. +<ul> +<li>If the gradient is cyclic then the points on the extended +P1, P2 connecting line cycle back and forth between the colors C1 +and C2. +<li>If the gradient is acyclic then points on the P1 side of +the segment have the constant Color C1 while points on the P2 side +have the constant Color C2. +The two colors are defined in a nested point tag of this tag. +point +

Attributes
cyclic
+Does the gradient cycle repeatedly between the two colors C1 and C2. +false +

+ <colorpaint> +

+Fills the area defined by the parent tag with a color. +

Attributes
color
+The color to be used to fill the parent tag's area. +The color definition is compatible with the +HTML one. E.g. black is '#000000' and red is '#FF0000'. However it +is possible to append two hex numbers for the alpha channel. Thus +'#FF000080' is red with alpha blending of 50%. +
required=true
rtexprvalue=true

+ <texturepaint> +

+The texturepaint tag provides a way to fill the area of the parent tag +with a texture that is specified as an image. The texture is anchored to +the upper left corner of the parent tags area. +

Attributes
