Processor/%name%/Mask/%index%/{Value}
The value that will be set to all the pixels within the mask. Default is 1

Parameters

data	the container containing the mask where the element should be added
s	the settings element to read the mask element parameters from

void pp240::ellipse	(	result_t &	data,
		CASSSettings &	s
	)

private

add a ellipsodial element to the mask

adds an ellipsodial to the mask. Will iterate trhough the sqare that contains the ellipse and checks which pixels should be masked.

User definable Parameters:

Processor/%name%/Mask/%index%/{CenterX|CenterY}
The central point of the ellipse. Default is 500|500.

Processor/%name%/Mask/%index%/{SemiAxisX|SemiAxisY}
The semi axis along x and y of the ellipse. By definition the longer one defines the major axis and the smaller on the minor axis. Default is 5|4.

Processor/%name%/Mask/%index%/{Value}
The value that will be set to all the pixels within the mask. Default is 1

Parameters

data	the container containing the mask where the element should be added
s	the settings element to read the mask element parameters from

void pp240::ring	(	result_t &	data,
		CASSSettings &	s
	)

private

add a ring

define the ring by two ellipses; an inner and outer ellipse. The area covered by the out but not by the inner will be masked. The two ellipsoids can have different centers and axis. Therefore the ring can take any shape.

User definable Parameters:

Processor/%name%/Mask/%index%/{InnerCenterX|InnerCenterY}
The central point of the inner ellipse. Default is 500|500.

Processor/%name%/Mask/%index%/{InnerSemiAxisX|InnerSemiAxisY}
The semi axis along x and y of the inner ellipse. By definition the longer one defines the major axis and the smaller on the minor axis. Default is 5|4.

Processor/%name%/Mask/%index%/{OuterCenterX|OuterCenterY}
The central point of the outer ellipse. Default is 500|500.

Processor/%name%/Mask/%index%/{OuterSemiAxisX|OuterSemiAxisY}
The semi axis along x and y of the outer ellipse. By definition the longer one defines the major axis and the smaller on the minor axis. Default is 20|20.

Processor/%name%/Mask/%index%/{Value}
The value that will be set to all the pixels within the mask. Default is 1

	)

private

add a square element to the mask

sets all pixels covered by the square to 0.

User definable Parameters:

Processor/%name%/Mask/%index%/{LowerLeftX|LowerLeftY}
The lower left pixel of the square element. The indizes given are included in the square. Default is 0|0.

Processor/%name%/Mask/%index%/{UpperRightX|UpperRightY}
The upper right pixel of the square element. The indizes given are included in the square. Default is 1023|1023.

Processor/%name%/Mask/%index%/{Value}
The value that will be set to all the pixels within the mask. Default is 1

void pp240::triangle	(	result_t &	data,
		CASSSettings &	s
	)

private

add a triangluar element to the mask

To see whether a point is within a triangle one can use barycentric coordinates. See http://en.wikipedia.org/wiki/Barycentric_coordinates_(mathematics) for details. A point within barycentric can be defined by converting to these coordinates. The bayrocentric coordinates are represented by three points A, B, C. Each point can be represented by $\vec{P} = \lambda_1\vec{A} + \lambda_2\vec{B} + \lambda_3\vec{C}$ where $\lambda_1, \lambda_2, \lambda_3$ can be determined from $\vec{P}$ using the components of the triangle points and the wanted point $\vec{P} = (x,y) ; \vec{A} = (x_1,y_1); \vec{B} = (x_2,y_2); \vec{C} = (x_3,y_3)$ with these definition the following equalities are given:

$\begin{eqnarray*} \lambda_1&=&\frac{(y_2-y_3)(x-x_3)+(x_3-x_2)(y-y_3)}{(y_2-y_3)(x_1-x_3)+(x_3-x_2)(y_1-y_3)}\\ \lambda_2&=&\frac{(y_3-y_1)(x-x_3)+(x_1-x_3)(y-y_3)}{(y_2-y_3)(x_1-x_3)+(x_3-x_2)(y_1-y_3)}\\ \lambda_3&=&1-\lambda_1-\lambda_2 \end{eqnarray*}$

With this we know that $\vec{P}$ lies within the triangluar when

$0 \leq \lambda_i \leq 1$

User definable Parameters:

Processor/%name%/Mask/%index%/{PointA_X|PointA_Y}
The triangles first point. Default is 500|500.

Processor/%name%/Mask/%index%/{PointB_X|PointB_Y}
The triangles first point. Default is 500|500.

Processor/%name%/Mask/%index%/{PointC_X|PointC_Y}
The triangles first point. Default is 500|500.

Processor/%name%/Mask/%index%/{Value}
The value that will be set to all the pixels within the mask. Default is 1
