PyPixelArt - A keyboard-centered pixel editor

Overview

PyPixelArt - A keyboard-centered pixel editor

pypixelart-compressed

The idea behind PyPixelArt is uniting:

  • a cmdpxl inspired pixel image editor applied to pixel art.
  • vim 's keyboard-centered approach to improve productivity. Pretty hard to do with an image editor, but it'll be fun to try xD
  • Some very useful functionalities from aseprite and other pixel art editors, such as screen symmetry.

Features and keybindings

  • Draw : i
  • Erase: x
  • Undo: u
  • Save: w
  • Zoom: n, b
  • Move Cursor: k, j, l, h
  • Grid: g
  • Symmetry: s
  • Color selection: c
  • Color: 1, 2, 3, 4, 5, 6
  • Help: Space

Installation

Install the package with:

pip install pypixelart

Usage

Run with pypixelart.

You can also specify the file path and resolution: for example, to create a new image that is 20px wide and 10px tall you can use

pypixelart -f new_image.png -res 20,10

To get the full list of options:

$ pypixelart --help
Usage: pypixelart [OPTIONS]

Options:
  -f, --filepath PATH      Path for the file you want to open
  -res, --resolution TEXT  Image height and width separated by a comma, e.g.
                           20,10 for a 20x10 image. Note that no spaces can be
                           used.
  --help                   Show this message and exit.

  • Fixed a bug where symmetric pixels wouldn't be drawn or erased if the corresponding pixel was already colored or blank, respectively.

    #13

    What does this implement?

  • Allow drawing symmetric pixel when the pixel at the cursor has the same color

    Allow drawing symmetric pixel when the pixel at the cursor has the same color

    After drawing a pixel, setting symmetry on and drawing again the symmetric pixel is not drawn. This happens because of the validation that returns from the draw_pixel function if the current pixel is already of the same color. Fix it so that it is possible to draw a symmetric pixel if the pixel at the cursor already is of that color.

  • Added symmetry functionality to the erase_pixel function.

    Added symmetry functionality to the erase_pixel function.

    #18

    What does this implement?

    This expands the symmetry functionality — that was already present in the draw_pixel function — to the erase_pixel function.

  • Rework the undo function

    Rework the undo function

    The current implementation of the undo function is not following the proper design pattern for it and works by indefinitely copying the image into a list, which is very inefficient and problematic. Rework the function following the proper pattern, improving memory efficiency, and limiting the number of times the undo can be done. A redo keybinding would be great as well, but not necessary.

  • Use lines to draw grid

    Use lines to draw grid

    The draw_grid function works in a very inefficient manner, by drawing a square for every pixel. Draw it using lines instead, creating horizontal and vertical lines covering the whole grid.

  • Improve zoom's initialization value

    Improve zoom's initialization value

    The current zoom value is initialized to a fixed value of 1000% of the image size. For very small images this makes the UI text clip, and for big images, the image overflows the screen. To avoid this, initialize the zoom value to make the image take a portion of the current screen size.

  • Add logging

    Add logging

    The package was made without the use of logging, which is really bad for debugging and maintenance in general, so for this issue:

    • Create a click command-line option to pass the logging level.
    • Add logging to track application events.

  • Inform the user when saving an image

    Inform the user when saving an image

    ~~The current saving function writes to the console to say the image was saved. It should show a dialog with text saying whether it saved successfully(and the path, if so) or if there was an error, say so and log the exception.~~

    Instead of a dialog, it would make more sense to do it like vim and show the message in #15's input after writing :w, so this issue now depends on #15 being completed.

  • Load palettes from lospec API

    Load palettes from lospec API

    Use the lospec API to load and save palettes to JSON files. Depends on #15 because this'll work with a command and on #6 because currently, the palettes are built-in, not loaded from files.

  • Add an input field to enter commands

    Add an input field to enter commands

    When the user presses escape or CTRL + c, show an input field at the bottom of the screen that gets input, just like vim's. Close if one of the buttons to show it is pressed again. If enter is pressed, try to run the command and show an error message where the input is if the command errors out or doesn't exist. No commands need to be implemented yet, just make a working input field.

  • Navigation improvements

    Navigation improvements

    Add more vim navigation keybindings:

    • $ or A to go to the end of a row
    • G to go the bottom left, num + G to go to the num row
    • num + h / j / k / l to move num in any direction
    • 0 to go to the start of a line Depends on #5 because of keybinding conflicts
