Drawing Methods

addsubshape(
 string shapename( ,
 int width,
 int height ) )

Adds a sub-shape with the name shapename that must be defined within the current shape definition

arc(
 int left,
 int top,
 int right,
 int bottom,
 int startingpointx,
 int startingpointy,
 int endingpointx,
 int endingpointy)

Draws an elliptical anticlockwise arc with the ellipse having extents at left, top, right and bottom

The start point of the arc is defined by the intersection of the ellipse and the line from the center of the ellipse to the point (startingpointx, startingpointy)

The end of the arc is similarly defined by the intersection of the ellipse and the line from the center of the ellipse to the point (endingpointx, endingpointy)

For example:

Arc(0, 0, 100, 100, 95, 0, 5, 0);

arcto(
 int left,
 int top,
 int right,
 int bottom,
 int startingpointx,
 int startingpointy,
 int endingpointx,
 int endingpointy)

As for the arc method, except that a line is drawn from the current position to the starting point of the arc, and then the current position is updated to the end point of the arc

bezierto(
 int controlpoint1x,
 int controlpoint1y,
 int controlpoint2x,
 int controlpoint2y,
 int endpointx,
 int endpointy)

Draws a bezier curve and updates the pen position

defSize(int width, int height)

Sets the default size of the element

This can appear in IF and ELSE clauses with different values in each, and causes the element to be resized automatically each time the values change; for example:

  if(HasTag("horizontal","true")) {
           defSize(100,20);
           rectangle(0,0,100,100);
  }
  else {
           defSize(20,100);
           rectangle(0,0,100,100);
  }
 
The above example sets the shape to the specified default size each time the Tagged Value horizontal is changed

When this is set, (Alt+Z) also resizes the shape to the defined dimensions

The minimum value for both int width and int height is 10

drawnativeshape()

Causes Enterprise Architect to render the shape using its usual, non-Shapescript notation; subsequent drawing commands are super-imposed over the native notation

This method is only enabled for element Shape Scripts; line Shape Scripts are not supported

ellipse(
 int left,
 int top,
 int right,
 int bottom)

Draws an ellipse with extents defined by left, top, right and bottom

endpath()

Ends the sequence of drawing commands that define a path

fillandstrokepath()

Fills the previously defined path with the current fill color, then draws its outline with the current pen

fillpath()

Fills the previously defined path with the current fill color

hidelabel(
 string labelname)

Hides the label specified by labelname, where labelname is one of the following values:

• middletoplabel
• middlebottomlabel
• lefttoplabel
• leftbottomlabel
• righttoplabel
• rightbottomlabel

image(
 string imageId,
 int left,
 int top,
 int right,
 int bottom)

Draws the image that has the name imageId in the Image Manager

The image must exist within the model in which the stereotype is used; if it does not already exist in the model, you must import it as reference data or select it from within a technology file

If the image is in a technology file, it should have a filename of the format <technology ID>::<imagename>.<extension>

Reference data

Adding images in MDG technology

lineto(
 int x,
 int y)

Draws a line from the current cursor position to a point specified by x and y, and then updates the pen cursor to that position

moveto(
 int x,
 int y)

Moves the pen cursor to the point specified by x and y

polygon(
 int centerx,
 int centery,
 int numberofsides,
 int radius,
 float rotation)

Draws a regular polygon with center at the point (centerx, centery), and numberofsides number of sides

print(
 string text)

Prints the specified text string

You cannot change the font size, type or color of this text

printifdefined(
 string propertyname,
 string truepart( ,
 string falsepart ) )

Prints the truepart if the given property exists and has a non-empty value, otherwise prints the optional falsepart

You cannot change the font size, type or color of this text

println(
 string text)

Appends a line of text to the shape and a line break

You cannot change the font size, type or color of this text

printwrapped(
 string text)

Prints the specified text string, wrapped over multiple lines if the text is wider than its containing shape

You cannot change the font size, type or color of this text

rectangle(
 int left,
 int top,
 int right,
 int bottom)

Draws a rectangle with extents at left, top, right, bottom. Values are percentages

roundrect(
 int left,
       int top,
       int right,
       int bottom,
       int abs_cornerwidth,
       int abs_cornerheight)

Draws a rectangle with rounded corners, with extents defined by left, top, right and bottom

The size for the corners is defined by abs_cornerwidth and abs_cornerheight; these values do not scale with the shape

setdefaultcolors()

Returns the brush and pen color to the default settings, or to the user-defined colors if available

Color Queries

setfillcolor(
 int red,
 int green,
 int blue)

setfillcolor(
 Color newColor)

Sets the fill color

You can specify the required color by defining RGB values or using a color value returned by any of the Color Queries such as:

GetUserFillColor()

Color Queries

setfixedregion(
 int xStart,
 int yStart,
 int xEnd,
 int yEnd)

Fixes a region in a connector into which a subshape can be drawn, so that the subshape is not rescaled with the length or orientation of the connector line

For an example, see the end of the table in the Example Scripts topic

Example Scripts

relativeTo is one of N, NE, E, SE, S, SW, W, NW, CENTER

xOffset and yOffset are in pixels, not percentage values, and can be negative

setpen(
 int red,
 int green,
 int blue( ,
