.. _glyph: Glyph ----- .. class:: Glyph Syntax: ``g = h.Glyph()`` Description: Specification of a drawing. The drawing can be rendered on a Graph as many times as desired using .. code-block:: none graph.glyph(g, x, y, scalex, scaley, angle) The drawing style uses commands reminiscent of postscript. Example: Rotated ellipse .. code-block:: python 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) .. image:: ../images/glyphcircle.png :align: center .. seealso:: :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. .. seealso:: :meth:`Graph.gif`, :meth:`Graph.glyph`
