imggg - go's image generic geometrics, reimplements image.Point and image.Rectangle to work with any number type you want: int, int8, int16, int32, int64, float32, float64, uint, uint8, uint16, uint32, uint64, uintptr, instead of just int.

Features:

• All the same methods and functions as image, the code is modified directly from https://go.dev/src/image/geom.go.
• Cast them back to the standard library equivalent with the Std() method.
• Get X and Y of a point as two variables quickly with the XY() method.
• Multiply a point by another point with the MulPt() method.

Library made for the egriden game framework. .

Note

Using points and rectangles with floats changes their logic from the intentions of the image library, read more on The Go Blog about the package.

Warning

Operations on unsigned integers is not tested, just try not to underflow things.

Usage

package main

import (
    "github.com/greenthepear/imggg"
    "image"
)

func main(){
    // Be implicit
    floatPoint1 := imggg.Pt[float64](0.2,0.1)
    // Let the compiler figure it out
    floatPoint2 := imggg.Pt(1.6,2.2)
    // Use the classic methods
    rec := imggg.Rectangle[float64]{
		floatPoint1.Mul(10),
		floatPoint2.Div(0.1),
	} // (2,1)-(16,22)

    // Work with the standard library
    img := image.NewRGNA(
        rec.Std()
    )
    ...
}
