class turtlethread.Turtle(pattern=None, scale=1, angle_mode='degrees', mode='standard')[kilde]#

Turtle object that to make embroidery files. Mirrored after the official turtle library.

This class has the same API as the builtin turtle.Turtle class with documented changes, for more information see the official documentation of the builtin turtle library

One turtle-step is equivalent to 0.1 mm (unless scaled otherwise).

Parameters:
patternturtlethread.stitches.EmbroideryPattern (optional)

The embroidery pattern to work with. If not supplied, then an empty pattern will be created.

scalefloat (optional, default=1)

Scaling between turtle steps and units in the embroidery file. Below are some example scaling

  • scale=1 - One step is one unit in the embroidery file (0.1 mm)

  • scale=10 - One step equals 1 mm

  • scale=2 - The scaling TurtleStitch uses

angle_mode«degrees» or «radians» (optional, default=»degrees»)

How angles are computed.

mode«standard», «world» or «logo» (optional, default=»standard»)

Mode «standard» is compatible with turtle.py. Mode «logo» is compatible with most Logo-Turtle-Graphics. Mode «world» is the same as ’standard’ for TurtleThread.

Mode

Initial turtle heading

Positive angles

"standard"

To the right (east)

Counterclockwise

"logo"

Upward (north)

Clockwise

property angle_mode#

The angle mode, either «degrees» or «radians».

circle(radius, extent=None, steps=None)[kilde]#

Draw a circle or arc, for more info see the official turtle.circle() documentation.

Parameters:
radius: float

Radius of the circle

extent: float

The angle of the arc, by default it is a full circle

steps: float

The circle is approximated as a sequence of steps line segments. If the steps are not given, then the optimal number of line segments for the current stitch length is selected.

cleanup_stitch_type()[kilde]#

Cleanup after switching stitch type.

home()[kilde]#

Move the needle home (position (0, 0)), for more info see the official turtle.home() documentation

jump_stitch(skip_intermediate_jumps=True)[kilde]#

Set the stitch mode to jump-stitch and cleanup afterwards.

With a jump-stitch, trim the thread and move the needle without sewing more stitches.

Parameters:
skip_intermediate_jumpsbool (optional, default=True)

If True, then multiple jump commands will be collapsed into one jump command. This is useful in the cases where there may be multiple subsequent jumps with no stitches inbetween. Multiple subsequent jumps doesn’t make sense but it can happen dependent on how you generate your patterns.

running_stitch(stitch_length)[kilde]#

Set the stitch mode to running stitch and cleanup afterwards.

With a running stitch, we get stitches with a constant distance between each stitch.

One step is equivalent to 0.1 mm, we recommend setting the minimum length between each stitch to 30 (3 mm).

Parameters:
stitch_lengthint

Number of steps between each stitch.

save(filename)[kilde]#

Save the embroidery pattern as an embroidery or image file.

Saves the embroiery pattern to file. Supports standard embroidery file formats, such as .dst, .jef and .pes, and utility formats such as .png, .svg and .txt. For a full list of supported file formats, see the pyembroidery documentation.

Parameters:
filenamestr
show_info()[kilde]#

Display information about this turtle’s embroidery pattern.

start_jump_stitch()[kilde]#

Set the stitch mode to jump-stitch (not recommended, use jump_stitch-context instead).

With a jump-stitch, trim the thread and move the needle without sewing more stitches.

start_running_stitch(stitch_length)[kilde]#

Set the stitch mode to running stitch (not recommended, use running_stitch-context instead).

With a running stitch, we get stitches with a constant distance between each stitch.

One step is equivalent to 0.1 mm, we recommend setting the minimum length between each stitch to 30 (3 mm).

It is recommended to use the running_stitch-context instead of the start-functions since they will automatically cleanup afterwards.

Parameters:
stitch_lengthint

Number of steps between each stitch.

start_triple_stitch(stitch_length)[kilde]#

Set the stitch mode to triple stitch (not recommended, use triple_stitch-context instead).

Triple stitch is equivalent to running stitch, but the thread moves back and forth three times for each stitch.

One step is equivalent to 0.1 mm, we recommend setting the minimum length between each stitch to 30 (3 mm).

Parameters:
stitch_lengthint

Number of steps between each stitch.

triple_stitch(stitch_length)[kilde]#

Set the stitch mode to triple stitch and cleanup afterwards.

Triple stitch is equivalent to running stitch, but the thread moves back and forth three times for each stitch.

One step is equivalent to 0.1 mm, we recommend setting the minimum length between each stitch to 30 (3 mm).

Parameters:
stitch_lengthint

Number of steps between each stitch.

visualise(turtle=None, width=800, height=800, scale=1, done=True, bye=True)[kilde]#

Use the builtin turtle library to visualise this turtle’s embroidery pattern.

Parameters:
patternpyembroidery.EmbPattern

Embroidery pattern to visualise

turtleturtle.Turtle (optional)

Python turtle object to use for drawing. If not specified, then the default turtle is used.

widthint

Canvas width

heightint

Canvas height

scaleint

Factor the embroidery length’s are scaled by.

donebool

If True, then turtle.done() will be called after drawing.

byebool

If True, then turtle.bye() will be called after drawing.
