d2d - draw 2D

the most minimal, probably most lacking, but simple 2d drawing Go package

What can it do ?

Draw

• Points
• Lines
• Rectangles (Filled and empty)
• Circles (Filled and empty)

of any color that satisfies basic stdlib's color.Color interface

Installation

go get unbewohnte.su:3000/Unbewohnte/d2d - if it doesn't work, your best choice is to just download it manually or copy-paste the code into your project

Usage

The main part of the package - Canvas struct that is essentially just a wrapper to draw.Image. Though the drawing can be done via direct work with shapes, canvas comes with additional quality of life drawing functions such as Border, FillWhole, Grid, FloodFill.

Example

canvas := d2d.NewCanvas(1920, 1080)
canvas.FillWhole(color.RGBA{60, 180, 30, 255})
canvas.Border(5, color.Black)
canvas.DrawFilledCircle(shapes.NewCircle(image.Pt(500, 500), 80), color.Black)
canvas.DrawLine(shapes.NewLine(image.Pt(0, 0), image.Pt(1920, 1080)), color.Black)
canvas.DrawFilledTriangle(
    shapes.NewTriangle(
        image.Pt(900, 20),
        image.Pt(1400, 400),
        image.Pt(500, 300),
    ),
    color.Black,
)

err := canvas.SaveAsPNG("image.png")
if err != nil {
    panic(err)
}
