GoodNotes Template Generator

This template generator will generate PDF templates for GoodNotes. Its a highly customizable Python script, that uses python scripts as patterns, a json file as the source of the color theme and a json file as a library of paper formats.

Usage

1. Clone the repository to your local machine:

   git clone https://github.com/rekkep/goodnotes_template_generator.git

2. Navigate to the project directory:

   cd goodnotes_template_generator

3. Run the script with the desired paper size:

   python generate_pdfs.py <paper_size> <theme> --patterns <pattern> --orientation <orientation> --density <density> --margin <margin> --thickness <thickness>

   Available default paper sizes: all, a3, a4, a5, a6, a7, standard_landscape, goodnotes_standard, letter, tabloid

   Available default themes: dracula, default_white, default_dark, default_yellow, black, midnight, onenote, notability-classic, template (All themes must be in lowercase)

   Available default patterns: all, blank, dots, hexagons, lines, squares

   density: how dense the pattern should be (doesn't work with hexagon)

   Available orientations: all, landscape, portrait

   thickness: line/dot thickness

   For example:

   python generate_pdfs.py a4 dracula

4. The generated PDF templates will be stored in the out\{theme}\{paper_format} directory.

TODOs

• remove unnecessary arguments from pattern functions
• option for perfect fitted squares (see patterns\helper\perfect_fill.py)
• more patterns
  • lines with different thickness
  • squares with sub squares

Requirements

• Python >= 3.13.0 (Haven't tried lower versions)
• reportlab (pip install reportlab)

Customization

Adding new Themes:

Open themes\themes.json and add a new theme. Themes need to follow the given format:

"template_name": {
        "inspiration": "inspired by", // optional
        "background_color": "HexColorCode",
        "line_color": "HexColorCode"
    }

Adding new Paper Sizes:

Open \paper_size\paper_sizes.json and add a new paper size. Paper sizes need to follow the structure:

"paper_name": [width_in_pixel, height_in_pixel]

Adding new Patterns:

Add your pattern as a .py file in the patterns dir. This file should generate the pdf inside the generate_template function. As for now, the function can only accepts output_file, paper_format, density, margin, theme, thickness as options and all of them must be present. Therefor the pattern-file should look something like this:

from reportlab.pdfgen import canvas

def generate_template(
    output_file: str,
    paper_format: tuple,
    theme: dict,
    density: int,
    margin: list,
    thickness: float
    ):

    width, height = paper_format
    c = canvas.Canvas(output_file, pagesize=(width, height))

    # Apply background color
    c.setFillColor(theme['background_color'])
    c.rect(0, 0, width, height, fill=True, stroke=False)
    
    c.save()

Examples

Dots with dracula theme and thickness of 1:

Hexagons with all helplines and in the Midnight theme:

Hexagons with no helplines and in the GoodNotes yellow theme:

Lines with Notability-classic theme and [20, 20, 20, 20] as margin

Squares with OneNote theme

Best Options

Lines

--margin "[30,40,20,20]"
--density 35

Squares

--margin "[-5, -5, -5, -5]"
--density 54

Dots

--margin "[-5, -5, -5, -5]"
--density 54
--thickness 0.5
