gridder

Built on top of Go Graphics github.com/fogleman/gg with the idea to simplify visualizing Grids using 2D Graphics.
Dependencies
Install
go get github.com/shomali11/gridder
Examples
Example 1
Exploring the GridConfig
configuration object. The Rows
and Columns
represent the rows and columns of the grid you wish to visualize. You can customize the grid by playing various options from style, color and width.
package main
import (
"image/color"
"log"
"github.com/shomali11/gridder"
)
func main() {
imageConfig := gridder.ImageConfig{Name: "example1.png"}
gridConfig := gridder.GridConfig{
Rows: 4,
Columns: 8,
MarginWidth: 0,
LineDashes: 0,
LineStrokeWidth: 2,
BorderDashes: 0,
BorderStrokeWidth: 10,
LineColor: color.Gray{},
BorderColor: color.RGBA{B: 255, A: 255},
BackgroundColor: color.White,
}
grid, err := gridder.New(imageConfig, gridConfig)
if err != nil {
log.Fatal(err)
}
grid.SavePNG()
}
[Result](examples/example1/example1.png)
Example 2
Exploring the ImageConfig
configuration object. This defines the image that will be generated. You can customize the Width
and Height
to generate larger images.
package main
import (
"image/color"
"log"
"github.com/shomali11/gridder"
)
func main() {
imageConfig := gridder.ImageConfig{
Width: 500,
Height: 500,
Name: "example2.png",
}
gridConfig := gridder.GridConfig{
Rows: 4,
Columns: 4,
MarginWidth: 20,
LineDashes: 10,
LineStrokeWidth: 2,
BorderDashes: 20,
BorderStrokeWidth: 4,
LineColor: color.RGBA{R: 255 / 2, A: 255},
BorderColor: color.RGBA{B: 255 / 2, A: 255},
BackgroundColor: color.RGBA{G: 255 / 2, A: 255},
}
grid, err := gridder.New(imageConfig, gridConfig)
if err != nil {
log.Fatal(err)
}
grid.SavePNG()
}
[Result](examples/example2/example2.png)
Example 3
