Drawing Pride Flags in Python using the drawsvg library.

See examples.ipynb for examples of how to make flags. :)

Basic drawing

Support for drawing as SVG and PNG:

Stripes:

• Horizontal lines
• Vertical lines
• Diagonal lines in the style of the Disability Pride Flag
• Reverse diagonal lines like in anarchist flags
• Seychelles-style lines
• Starburst-type patterns
• Concentric bézier curves in the style of the Mental Health Flag
• Concentric infinity symbols in the style of the Autistic Pride Day logo
• Concentric vees in the style of the varsex flag
• Concentric rectangles in the style of the kymenic flags
• Combining horizontal & vertical lines in the style of the Buddhist flag

Circular shapes:

• Standard Carpenter intersex flag ring
• Concentric rings
• Segmented rings
• Insetting a flag inside a Carpenter ring
• Solid circles
• Solid ellipses
• Concentric ellipses and circles
• Belt like in the Voidpunk flag

Triangular shapes:

• Piles (the triangle that goes on the left-hand side of the Demisexual flag)
• Nested piles (like in the Progress Pride flag)
• Asymmetric piles (like in the tricolour Polyamory flag)
• Inverted triangles like in the Pink Triangle flag
• Ally A (upside-down chevron)
• Inner triangles in the style of the Bissu flag
• The Therian symbol (triangle & circle)

Stars:

• Five-pointed stars
• The five-pointed star with two path lines used in the Outernaut, Varinaut, etc flags
• Stars of David (both standard and outline-only)
• The seven-pointed star used for Otherkin flags
• The Nonhuman Unity symbol
• The Southern Cross
• Stars of arbitrary numbers of points, both traced out and filled in

Crosses and Xs:

• Crosses (like in the Ipsogender flag)
• X-crosses (like in the Crossdresser flag)
• 4-part X (like in the X-Gender flag)
• Concentric Xs (like in the Quasigender flags)
• Concentric Ts (like in the Tgirl flag)

Gender Symbols:

• Gender neutral symbol
• Mars symbol
• Mercury symbol
• Transgender symbol
• Venus symbol
• Xenous symbol

And other possible flag elements:

• Text (e.g. the original Polyamory flag)
• Squares (like in the Dyadic and Endosex flags)
• Half-squares (cut along diagonal, useful for endosex/dyadic flags)
• The rectangular shape used for the Caed- flags (e.g. Caedsexual, Caedromantic)
• Rhombi (squares rotated 45 degrees, used in an Altersex flag)
• Diamonds (rhombi that are squished horizontally)
• Hearts (like in the Biromantic flag)
• The round shape on the side of the Peri- and Varioriented flags
• The Rubber Zigzag
• BDSM Triskelion
• Armpit Fetish stripe shape
• Longhair Fetish shape
• The Pocketgender Flag
• Closet symbols
• Perisex symbols
• Altersex symbols
• Autism spectrum nautilus symbols
• Open infinity symbols
• Métis lemniscates
• Equals symbols like in the alternate Androgyne flag
• The Bipolar Flag
• The Utrinque Zigzag

Examples of use

A Jupyter notebook of examples is available in this directory (examples.ipynb).

Many of the same examples are also available in drawflags/examples.py for even more illustrative examples. Here are just two:

intersex_yellow = '#FDD70A'
intersex_purple = '#7A01AA'
trans_pink = '#F5A9B8'
trans_blue = '#5BCEFA'
trans_stripes = [trans_pink, trans_blue, 'white', trans_blue, trans_pink]

d = draw.Drawing(500, 300)
draw_inset_into_intersex(d, trans_stripes, intersex_yellow, intersex_purple, orientation=HORIZONTAL)
d.save_svg(outdir + 'intersextrans.svg')

d = draw.Drawing(500, 300)
draw_reverse_diagonal_stripes(d, ['#626eb7', '#c7d6ff'])
draw_square(d, 'black')
draw_diagonal_cut_square(d, 'white')
d.save_svg(outdir + 'endosex.svg')

Typical parameters

The standard parameters of a given drawing function (e.g. draw_heart, draw_ellipse, draw_concentric_rectangles, etc) are:

• d: a mutable drawing object that is altered by the function
• colour is specified by either:
  • colours: a list of hex strings
  • primary_colour and (optional) secondary_colour (both hex strings)
• and optional parameters:
  • wid: the width of the rectangular area in which things will be drawn into (defaults to 100% of the width of d's canvas)
  • hei: the height of the rectangular area in which things will be drawn into (default: 100% of d's canvas height)
  • x_start: the x-coordinate of the upper left corner of the rectangular area into which things will be drawn (default: 0)
  • y_start: the y-coordinate of the upper left corner of the rectangular area into which things will be drawn (default: 0)
  • size_ratio: a scaling factor that generally corresponds to the radius (or equivalent) of the object being drawn
  • stretch_ratio: a scaling factor that generally affects the convexity of the object being drawn. Not always used.
  • thick_ratio: a scaling factor that generally corresponds to the line thickness of the stroke width used to draw a given object (usually an outline of the object). Not always used.
  • orientation: a string which indicates the orientation of the object being drawn. Default is always HORIZONTAL.
    • HORIZONTAL ('H'): the default option. ⬆️ Will put a heart in 💜 orientation and a star in ⭐️ orientation.
    • UPSIDE ('U'): 180 degrees of HORIZONTAL. ⬇️ Upside-down heart, upside-down star.
    • VERTICAL ('V'): 90 degrees from HORIZONTAL. ➡️ Will put a heart in the orientation for the tricolour polyamory flag.
    • ARROW ('A'): 180 degrees from VERTICAL. ⬅️
    • DIAGONAL ('D'): -45 degrees from HORIZONTAL. ↖️ Will align with the disability pride flag. Will put a heart in the orientation for the leather flag.
    • BEND ('B'): 180 degrees from DIAGONAL. ↘️
    • REVERSE ('R'): reverse diagonal or 90 degrees from DIAGONAL. ↗️ Used in many anarchist flags. Will put a star in the orientation needed for the boi+boy flag.
    • SINISTER ('S'): 180 degrees from REVERSE. ↙️ Will put a star in the orientation needed for the armpit fetish flag.

Or in order around a circle (clockwise): HORIZONTAL ⬆️, REVERSE ↗️, VERTICAL ➡️, BEND ↘️, UPSIDE ⬇️, SINISTER ↙️, ARROW ⬅️, DIAGONAL ↖️.

Many functions return a number that corresponds to a dimension of the object that was drawn. For example, draw_horiz_bars returns the height of the typical horizontal bar. This number can then be used by later function calls to scale other flag elements.

TODOs

Orientation support

• Rethink the multipile to make the geometry easier
• Vees
• Chevrons
• Seychelles
• Concentric Beziers
• Tees
• Square cutting
• Nautilus (beyond vertical/horiz)

Colour

• get the colour palette of a flag ordered by volume of flag
• get the colour palette of a flag ordered alphabetically in the style of Wikimedia Commons' flag categorization

Double check

• positioning of the dots in the triskelion

Embedding other SVGs

• right now this does what drawsvg does, i.e. embeds the other SVG as an image. Not ideal and should not be used for uploads to Wikimedia Commons.
