Tool Documentation
Welcome to the official tool documentation, here you'll find information on the current tools available in PixaPencil.
The pencil tool is the most basic and simple tool you'll find in the app. It functions exactly how a regular pencil tool might function in another pixel art application such as Aseprite.
To use the tool, simply tap, and while holding your finger on the screen, move it (your finger) to draw your desired path. If the result is too pixelated for your liking, then your canvas size may be too small.

The fill tool 'fills' adjacent pixels which are similar in color value with the user's selected color. This tool is useful when you might want to color in large areas inside your projects.

Using Bresenham's line algorithm, the line tool gives you the ability to draw pixelated lines.

The rectangle tool gives you the ability to draw filled or outlined rectangles.

The square tool gives you the ability to draw filled or outlined squares. It functions similarly to the rectangle tool, the only difference is that it allows you to draw perfect squares.

The square tool gives you the ability to draw filled or outlined circles using a modified midpoint circle algorithm.

The spray tool helps with simulating real life spray paint, but in pixel art form. By tapping on the spray paint icon (as demonstrated in the video below), the user can further refine the tool's 'Radius' and 'Strength' values.

The polygon tool allows you to draw polygonal paths by clicking on coordinates on the canvas. To start a new path, simply tap on the polygon icon (as demonstrated in the video below).

The dither tool allows you to draw checkerboard patterns. You will find this tool in many other pixel art apps, as it's renowned for its usefulness in shading or simply creating patterns. (Note that I am using a thicker brush for the video demonstration.)

The shading tool - as the name suggests - allows you to darken/lighten certain areas on the canvas. Simply tap on the tool icon to change shading modes (from lighten to darken or darken to lighten).
