Glyph

class Glyph
Syntax:

g = new 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.

Graph, Graph.glyph()


Glyph.new_path()
Syntax:

g = g.path()

Description:

Begin a new path.


Glyph.move_to()
Syntax:

g = g.m(x, y)

Description:

Set the current point to the coordinates.


Glyph.line_to()
Syntax:

g = g.l(x, y)

Description:

A line from the current point to the coordinates.


Glyph.curve_to()
Syntax:

g = g.curve(x,y, x1,y1, x2,y2)

Description:

Draw a curve from the current point to x,y


Glyph.close_path()
Syntax:

g = g.close()

Description:

A line from the current point to the first point of the path.


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.

Example:

Rotated ellipse

objref gr, gl
gr = new Graph()

gl = new Glyph()
gl.circle(0,0,1)
gl.fill(3)
gl.s(2, 3)

gr.glyph(gl, 150, 100, 30, 60, PI/4*DEG)

Glyph.stroke()
Syntax:

g = g.s()

g = g.s(colorindex)

g = g.s(colorindex, brushindex)

Description:

Render the current path as a line.


Glyph.fill()
Syntax:

g = g.fill()

g = g.fill(colorindex)

Description:

For a closed path, fill the interior with the indicated color.


Glyph.control_point()
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.


Glyph.erase()
Syntax:

g = g.erase()

Description:

The drawing is empty


Glyph.label()
Syntax:

g = g.label("string", x, y, fixtype, colorindex)

Description:

Not implemented


Glyph.glyph()
Syntax:

g = g.glyph(glyphobject, x, y, scale, angle)

Description:

Not implemented


Glyph.gif()
Syntax:

g = g.gif("filename")

Description:

Reads the gif image in the file. All 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.
