What is Lychee?

Lychee is a paint app designed to use code to draw images instead of brushstrokes. Lychee is built in pure Java, using the GUI framework Swing with no external dependencies. Lychee uses Zest, our custom programming language, to draw images. This has many advantages:

Smaller image files
More shareability
More friendship
More zestiness

You may be asking: why not just use SVG? Our answer: embrace the zest. Live the wild life. Live the Lychee life.

Why is Lychee?

Lychee is useful for a few different applications:

Simple graphic design work
Learning to code
Providing a more intuitive alternative to SVG

line([0:0], [100:100], 5, "red");
line([0:0], [100:100], 5, "#bf3344");

Parameters:

start: Coordinate
end: Coordinate
width: int
color: String

erase

Erases a straight line from the starting coordinates to the ending coordinates, using the provided width. Cannot be colored.

erase([0:0], [100:100], 5);

Parameters:

start: Coordinate
end: Coordinate
width: int

fill

Fills a rect with the chosen color from the starting coordinates, using the provided height and width.

fill([0:0], 50, 100, "red");
fill([0:0], 50, 100, "#bf3344");

Parameters:

start: Coordinate
width: int
height: int
color: String

circle

Draws a circle from the starting coordinates, using the provided height and width. Can be colored.

circle([0:0], 30, 30, "red");
circle([0:0], 30, 30, "#bf3344");

Parameters:

start: Coordinate
width: int
height: int
color: String

text

Draws text from the starting coordinates, using the provided font size. Can be colored.

text([50:50], 30, "hello", "red");
text([50:50], 30, "hello", "#bf3344");

Parameters:

start: Coordinate
fontSize: int
text: String
color: String

layer

Creates a layer. Commands in higher layers will be drawn over lower layers. Any command not inside a layer block will be drawn on layer 0.

layer(1) {
    //commands go here
}

Parameters:

layer: int

Notes

A color can be written as a word or a hexcode, but words have a limited selection of colors (black, white, red, orange, yellow, green, blue, purple, pink)
Coordinates are in [x:y] format
Zest supports comments on lines beginning with //
