how to run code

[shehzad021]

hello brother, this art is really amazing(contour line, noise line and dot line). I'm trying for 2 week to run the code but it's not working. Can you guide how to run and setup files.

[happyRip]

It's all documented, try those steps:

• create your project folder and enter that folder mkdir generativeart && cd generativeart
• initialize your go project with go mod init generativeart
• download required packages
  • go get github.com/jdxyw/generativeart
  • go get github.com/jdxyw/generativeart/arts
• copy any main from examples and save it as main.go file:

package main

import (
        "math/rand"
        "time"

        "github.com/jdxyw/generativeart"
        "github.com/jdxyw/generativeart/arts"
        "github.com/jdxyw/generativeart/common"
)

func main() {
        rand.Seed(time.Now().Unix())
        c := generativeart.NewCanva(500, 500)
        c.SetBackground(common.Black)
        c.FillBackground()
        c.SetColorSchema(common.DarkRed)
        c.SetForeground(common.LightPink)
        c.Draw(arts.NewJanus(10, 0.2))
        c.ToPNG("janus.png")
}

• run the code with go run .
• enjoy your image

can you explain first steps in more detail. I don't know too much about it

[happyRip]

Sure, the question is if you use windows, linux or macos?

[shehzad021]

windows

[happyRip]

For windows:

• open Windows PowerShell in search bar
• go to a directory you'd like to have your project stored in, for me it would be Documents:
  • cd Documents
    • you can specify a full path here, copied from the navigation bar of the File Explorer
      
      and use it as such cd C:\Users\<your_username>\Documents (absolute path)
    • some applications (like Windows Terminal) allow you to 'Open in ...' when you right-click in a folder
      
• from now on follow my previous instructions:

• create your project folder and enter that folder mkdir generativeart && cd generativeart ...

Bear in mind you need to have go installed https://go.dev/doc/install

please explain initialize step also

go mod init is a command that initializes your go project and creates the go.mod file, which is needed to download packages with go get ... command.

Here is the official documentation for the command https://go.dev/ref/mod#go-mod-init

go get ... updates the dependencies of your project. When using github.com/jdxyw/generativeart in your project, it becomes a dependency of your program, so you need to get it. In my test I had to get github.com/jdxyw/generativeart/arts as well

Here is the official documentation for the command https://pkg.go.dev/cmd/go#hdr-Add_dependencies_to_current_module_and_install_them

how can I change colors and save output file (.PNG)

[shehzad021]

and how to save png file

[jdxyw]

You could find this line below from the snippet posted above.

c.ToPNG("janus.png")

[shehzad021]

I want to change color of dot line art

[jdxyw]

You can change the color schema from https://github.com/jdxyw/generativeart/blob/master/example/example_dotline.go#L18. You could pass a predefined color schema or pass a customized color array by yourself.

[shehzad021]

it shows an error when I write any other colors.
# command-line-arguments .\main.go:19:19: undefined: common.Darkblue

[shehzad021]

it shows an error when I write any other colors.
# command-line-arguments .\main.go:19:19: undefined: common.Darkblue

[shehzad021]

No, how to use it.

[happyRip]

Each word begins with a capital letter, so of you have dark blue, you write DarkBlue, but please check if the colors you'd like to try are present in the file sent above

[shehzad021]

it didn't not I tried colors from the file like
LightPink

[jdxyw]

have you used the Go before? Can you run those examples under example folders?

[shehzad021]

all other examples are working with new colors define in common file but only dot line is not working.
