Functions

func CopyDir

func CopyDir(srcDir, dstDir string) error

CopyDir recursively copies a folder from src to dst

func DecodeImageFromBytes

func DecodeImageFromBytes(data []byte) (image.Image, error)

DecodeImageFromBytes decodes an image from a byte slice

func DiffImagesPink

func DiffImagesPink(img1, img2 image.Image) (diff *image.RGBA, mismatch float64)

DiffImagesPink compares two images and creates a diff image with pink highlights Only compares the overlapping region (intersection of both bounds)

func DiffImagesPinkWithBounds

func DiffImagesPinkWithBounds(img1, img2 image.Image) (diff *image.RGBA, mismatch float64)

DiffImagesPinkWithBounds compares two images and highlights out-of-bounds areas The diff image covers the union of both image bounds

func LoadImage

func LoadImage(path string) (image.Image, error)

LoadImage loads an image from a file path

func SaveImage

func SaveImage(path string, img image.Image) error

SaveImage saves an image to a file path

Types

type DimensionDiff

type DimensionDiff struct {
	WidthDiff  int // positive = test wider, negative = test narrower
	HeightDiff int // positive = test taller, negative = test shorter
}

DimensionDiff holds dimension difference information

func CompareDimensions

func CompareDimensions(img1, img2 image.Image) (same bool, diff DimensionDiff)

CompareDimensions checks if two images have the same dimensions
