- Syntax:
g = h.Glyph()- Description:
Specification of a drawing. The drawing can be rendered on a Graph as many times as desired using
graph.glyph(g, x, y, scalex, scaley, angle)
The drawing style uses commands reminiscent of postscript.
- Example:
Rotated ellipse
from neuron import h, gui gr = h.Graph() gl = h.Glyph() gl.circle(0,0,1) gl.fill(3) gl.s(2, 3) gr.glyph(gl, 150, 100, 30, 60, h.PI/4*h.DEG)

:class:`Graph`, :meth:`Graph.glyph`
.. method:: Glyph.path
Syntax:
``g = g.path()``
Description:
Begin a new path.
.. method:: Glyph.m
Syntax:
``g = g.m(x, y)``
Description:
Set the current point to the coordinates.
.. method:: Glyph.l
Syntax:
``g = g.l(x, y)``
Description:
A line from the current point to the coordinates.
.. method:: Glyph.curve
Syntax:
``g = g.curve(x,y, x1,y1, x2,y2)``
Description:
Draw a curve from the current point to x,y
.. method:: Glyph.close
Syntax:
``g = g.close()``
Description:
A line from the current point to the first point of the path.
.. method:: Glyph.circle
Syntax:
``g = g.circle(x, y, r)``
Description:
A circle at location x, y and radius r. This is implemented using
the glyph methods new_path, move_to, curve_to, and close_path.
Can stroke and/or fill.
.. method:: Glyph.s
Syntax:
``g = g.s()``
``g = g.s(colorindex)``
``g = g.s(colorindex, brushindex)``
Description:
Render the current path as a line.
.. method:: Glyph.fill
Syntax:
``g = g.fill()``
``g = g.fill(colorindex)``
Description:
For a closed path, fill the interior with the indicated color.
.. method:: Glyph.cpt
Syntax:
``g = g.cpt(x,y)``
Description:
Draw a small open rectangle at the coordinates. Intended to indicate
special locations on the glyph which can be selected. Not very useful
at this time.
.. method:: Glyph.erase
Syntax:
``g = g.erase()``
Description:
The drawing is empty
.. method:: Glyph.label
Syntax:
``g = g.label("string", x, y, fixtype, colorindex)``
Description:
Not implemented
.. method:: Glyph.glyph
Syntax:
``g = g.glyph(glyphobject, x, y, scale, angle)``
Description:
Not implemented
.. method:: Glyph.gif
Syntax:
``g = g.gif("filename")``
Description:
Reads the gif image in the file. All :class:`Glyph` arguments still work
when the glyph contains a gif image. The gif image is drawn first so
other drawing specs will appear on top of it.
