Known Subclasses:

MultiEpsDiagramDrawer

Class to write a EPS file containing the asked diagram This class follows the DrawDiagram Frameworks.

The main routine to draw a diagram is 'draw' which call 1) initialize: setup things for the diagram (usually open a file) 2) convert_diagram : Update the diagram in the correct format if needed 3) draw_diagram : Perform diagram dependent operation 4) conclude : finish the operation.

Instance Methods

[hide private]

initialize(self)
Operation done before starting to create diagram specific EPS content First open the file in write mode then write in it the header and the library of particle type.

source code

conclude(self)
Operation to perform when all code related to a specific diagram are finish.

source code

rescale(self, x, y)
All coordinates belongs to [0,1].

source code

line_format(self, x1, y1, x2, y2, name)
Specify the text format of a specific Particles.

source code

draw_vertex(self, vertex, bypass=['QED', 'QCD'])

draw_straight(self, line)
ADD the EPS code for this fermion line.

source code

draw_dashed(self, line)
ADD the EPS code for this Higgs line.

source code

draw_wavy(self, line, opt=0, type='d')

draw_scurly(self, line)
ADD the EPS code for this gluino line.

source code

draw_swavy(self, line)
ADD the EPS code for this neutralino line.

source code

draw_double(self, line, type='r')
ADD the EPS code for this neutralino line. source code

put_diagram_number(self, number=0)
ADD the comment 'diagram [number]' just below the diagram.

source code

Method Details

[hide private]

initialize(self)

source code

Operation done before starting to create diagram specific EPS content First open the file in write mode then write in it the header and the library of particle type.

Overrides: core.drawing.DiagramDrawer.initialize

conclude(self)

source code

Operation to perform when all code related to a specific diagram are
finish. Operation :
- Add the 'end of page' code
- write unwritten text and close the file. [DrawDiagram.conclude]

Overrides: core.drawing.DiagramDrawer.conclude

rescale(self, x, y)

source code

All coordinates belongs to [0,1]. So that in order to have a visible graph we need to re-scale the graph. This method distort the square in a oblong. Deformation are linear.

line_format(self, x1, y1, x2, y2, name)

source code

Specify the text format of a specific Particles. EPS format for Particle is either [X Y X Y NAME] or [X Y X Y NUM NAME]. In this routine we will consider only the first format. The second can be matched by redefining name in [NUM NAME].
