simple yet all you need for protyping

pysimpledraw

pysimpledraw is a simple drawing application built with Python, using FreeSimpleGUI for the graphical user interface and tkinter for canvas operations. It allows users to create and manipulate basic shapes, add text, import images, and perform common drawing operations.

Why pysimpledraw?

pysimpledraw aims to provide a lightweight and easy-to-use drawing tool for quick sketches, annotations, or simple diagrams. It serves as a demonstration of how to integrate FreeSimpleGUI with tkinter for creating interactive graphical applications.

Features

• Drawing Tools: Rectangle, Circle, Line, Freehand, Triangle, Diamond.
• Text Tool: Add and edit text on the canvas.
• Color Palette: Predefined colors (Black, Red, Green) and a custom color chooser.
• Line Thickness: Thin and Thick options.
• Eraser: Remove objects from the canvas.
• Object Manipulation:
  • Select and move objects.
  • Delete selected objects.
  • Resize text (Small, Medium, Large via context menu).
  • Resize imported images (via context menu with preset ratios).
• Image Import:
  • Import an image as a background.
  • Import pictures as draggable and resizable objects.
• Canvas Operations:
  • Clear All: Resets the canvas.
  • Undo/Redo: Revert and reapply actions.
  • Save: Save the current canvas content as an image (e.g., PNG).
  • Pan: Right-click and drag on empty canvas space.
• Context Menus:
  • Middle-click on text objects for size options.
  • Middle-click on image objects for resize options.
• Keyboard Shortcuts: Quick access to tools and actions.

Installation

1. Clone the repository (if applicable):

   git clone <your-repository-link>
   cd pysimpledraw
   

2. Ensure Python is installed. (Python 3.6+ recommended)
3. Install dependencies: The application relies on FreeSimpleGUI, Pillow (PIL), and pyperclip. You can install them using pip:

   pip install FreeSimpleGUI Pillow pyperclip
   

   Or, if a requirements.txt file is provided:

   pip install -r requirements.txt
   

   (Note: A pyproject.toml is present, which might be used with tools like Poetry or Hatch for dependency management. If so, follow their respective installation procedures.)

Usage

As a Standalone Script

Navigate to the directory containing main.py (e.g., pysimpledraw) and run:

python main.py

As a Package (using -m)

If pysimpledraw is structured as a runnable package (e.g., with an __main__.py or if main.py is intended to be run this way), you might be able to run it from the parent directory (pysimpledraw):

python -m pysimpledraw.main

(This assumes pysimpledraw is in your Python path or you are in the pysimpledraw directory which contains pysimpledraw.)

GUI Features and Operations

The application window is divided into sections: Instructions, Tools, and the Canvas.

Instructions Panel

• Mouse:
  • Left Button: Draw shapes or add text (double-click).
  • Middle Button: Access context menus for text (size) or images (resize).
  • Right Button: Select objects, move selected objects, or pan the canvas (if clicking on empty space).
• Double Click:
  • On an existing text object: Edit the text.
  • On an empty area: Place new text.
• Shortcuts: See the "Keyboard Shortcuts" section below.

Tools Panel

Shape Tools:

• r ectangle: Selects the rectangle drawing tool.
• c ircle: Selects the circle drawing tool.
• a rrow: Selects the arrow drawing tool.
• t line: Selects the line drawing tool.
• f ree: Selects the freehand drawing tool.
• T riangle: Selects the triangle drawing tool.
• d iamond: Selects the diamond drawing tool.
• e rase: Selects the eraser tool (click on an object to delete it).
