This is where I keep assorted Python scripts I write that support design tasks.
Extracts hexadecimal color codes from a text file and generates a PNG file and an SVG file with swatches of those colors.
Several styles of swatches are provided:
ball-grid creates a grid of spheres for each color. The highlight has a
lighter, less saturated variation of the color. The shadow has a darker, more
saturated variant of the color.
circle-grid creates a grid of circles for each color.
color-stack groups colors by hue with overlapping color circles.
gradient-bar groups colors by hue and creates a linear gradient using each
group. A stop is created for each color in the group and a group's stops are
equally spaced within that gradient.
square-grid creates a grid of squares for each color.
python -m designtools.extract_swatches [-h] [--style {ball-grid,gradient-bar,square-grid,circle-grid,color-stack}] text_file [swatch_file]
text_file: The text file to extract color codes from. This may be any text file that contains hexadecimal color codes.swatch_file: Optional. The name of the SVG file to create. If the argument is not given, the script will create a file with the same base name as the input file and append the extension.<style>.svgwhere<style>is replaced with the swatch style ('square-grid' by default).--style: Optional. The style of swatches to render. Valid options areball-grid,gradient-bar,square-grid,circle-grid, andcolor-stack.-h,--help: show the help message and exit.
Scales known numeric sequences around a given value and writes them as columns in a CSV file with sequence names in the first row.
Known sequences: Golden powers (20 values), Fibonacci (41 values), Lucas (39 values), Pell (32 values), Pell-Lucas (31 values), Metallic means (20 values)
python -m designtools.scale_sequence [-h] [--offset OFFSET] file value
file: The name of the CSV file to generate. This file will be overwritten if it already exists.value: The number to scale the sequences around.--offset OFFSET: Optional. The index within the sequence that should equal the given value after scaling. If offset is not given, the offset will be set to half the middle of the shortest known sequence.-h,--help: show the help message and exit.
Generates numeric sequences using known ratios and writes them as columns in a CSV file with sequence names in the first row.
Known ratios: Golden ratio, Supergolden ratio, Silver ratio, Plastic number, Minor second, Major second, Minor third, Major third, Perfect fourth, Augmented fourth, Perfect fifth
python -m designtools.make_sequence [-h] [--count COUNT] file seed
file: The name of the CSV file to generate. This file will be overwritten if it already exists.seed: The value to build the sequence around. This value will be in the middle of the returned sequence. This value may be a float or integer.--count COUNT: The number of items to be created before and after the seed value in the sequences. The count will default to 5 if not given. The length of each generated sequence will always be2 * count + 1.-h,--help: show the help message and exit.
designtools.colorcontains utilities for converting, grouping, and sorting colors.designtools.graphicscontains a utility for rendering color swatches as an SVG image.designtools.graphics.svgcontains a rudimentary (and very incomplete) SVG library based onxml.etree.ElementTree. It is not intended to be useful beyond the included scripts.designtools.mathutilcontains various mathematical constants, sequences, and utilities. This includes things like the Golden Ratio, Golden Angle, Pell numbers, and the Fibonacci sequence.
