Change Log¶
v0.8 - 15-Aug-2020
Changed Header anchors to pinN for consistency with Ic.
Improved label placement with respect to anchor positions.
Prevent duplicate figures from showing in Jupyter Element representation
Improvements for headless server operation to prevent popup window
Added some undocumented features to documentation
Added Drawing.get_imagedata function for returning raw image bytes
Fixed pip installation issue with module capitalization. Must import lowercase schemdraw.
v0.7.1 - 26-Jun-2020
Bug fix: restore usage outside of Jupyter, so that Matplotlib window is shown when calling Drawing.draw().
v0.7 - 21-Jun-2020
Dropped support for Python 2. Now requires 3.7+.
Elements are now subclasses of Element. Previous (dict) element names are translated into new class names. Any user-defined elements will need to be converted to classes. The group_elements function is replaced with ElementDrawing class.
Allow fontsize or size keyword arguments interchangeably in Drawing and add_label
Updated flow.Decision to use keyword arguments for labeling decision branches
The Ic element label offset parameter changed from lblofst to lofst to avoid conflict with the main element label.
Direct access to Drawing.fig and Drawing.ax are no longer available. Instead, Drawing.draw() returns a schemdraw.Figure instance with fig and ax attributes.
Implemented Jupyter representation functions for both Drawing and Element classes.

v0.6.0, 11-Feb-2020
Refactored internals to allow more control over individual components of drawing. Should have no effect unless the user is accessing internal attributes of the Element object. This also adds the segments list to the Element object, which allows finer control over individual bits of the drawing.
Updated add_label so that “top” labels should always appear on top, regardless of flip/reverse
Swapped the direction of current sources, so that a current source with direction “up” has the arrow pointing up.
Added “zorder” parameter in the element definition dictionary and add method
Added elements.ic and elements.multiplexer functions as replacements to blackbox and mux. These include more functionality such as adjusting indiviudal pin rotation, color, and inverter bubbles.
Labels can be placed relative to an anchor position using the add_label method. This could be useful, for example, in labeling pin numbers on a logic gate or opamp.
Added new anchors to OPAMPs for power supply and offset nulls.
- New Elements:
MIC
MOTOR
- Documentation:
Upgraded documentation to Sphinx and moved to readthedocs.org at https://schemdraw.readthedocs.io/en/latest/.
Changed preferred import to import SchemDraw.elements as elm. Apparently some people still use import * with pylab; this suggestion will help avoid conflicts.
- v0.5.0, 21-Jul-2019
Added flowcharting symbol methods to SchemDraw.flow module
Added signal processing symbols to SchemDraw.dsp module
Implemented fill parameter on Drawing.add to fill shapes and closed paths with a solid color
- New elements:
Fuse
CapacitorVar,
DiodeTunnel
Jfet
Diac
Triac
SCR
- v0.4.0, 03-Nov-2018
Fixed drawing of NOT and related gates to property extend the path
Fixed arrow translation when grouping elements
Fixed sidelabels and plabels of blackbox when empty
Fixed arc drawing due to change in Matplotlib 2.2 on asymmetric partial arcs
- v0.3.0, 03-Jul-2017
Added function for drawing multiplexers/demultiplexers
Updates to labelI() method to allow reversing arrow and changing length
Add CSS to documentation
