type GIFCompareOptions ¶ added in v0.9.0

type GIFCompareOptions struct {
	RequireFrameChange bool
	Image              imagediff.Options
}

GIFCompareOptions controls exact display-pixel comparison. When RequireFrameChange is true, a constant animation is rejected even if the expected file is also accidentally constant.

type GIFComparison ¶ added in v0.9.0

type GIFComparison struct {
	Expected, Actual *GIFInspection
	FrameIndex       int
	FrameResult      *imagediff.Result
}

GIFComparison contains the frame diagnostics available on a pixel mismatch. FrameResult can be written as a self-contained HTML report.

func CompareGIF(expectedBytes, actualBytes []byte, options GIFCompareOptions) (*GIFComparison, error)

type GIFInspection ¶ added in v0.9.0

type GIFInspection struct {
	Width, Height             int
	LoopCount                 int
	Delays                    []int
	TotalDurationCentiseconds int
	FrameHashes               [][sha256.Size]byte
	ChangedFramePairs         int
	// contains filtered or unexported fields
}

GIFInspection is the decoded, display-equivalent GIF contract used by the raster E2E suite. FrameHashes are hashes of composited NRGBA pixels in playback order, not hashes of palette indices or encoded bytes.

func InspectGIF(gifBytes []byte) (*GIFInspection, error)

type PDFImage ¶ added in v0.9.0

type PDFImage struct {
	ObjectNumber  int
	Width, Height int
	Pixels        *image.NRGBA
}

type PDFInspection ¶ added in v0.9.0

type PDFInspection struct {
	Pages         []PDFPage
	Images        []PDFImage
	ExternalLinks []string
	InternalLinks int
}

PDFInspection is the bounded structural and raster view of PDFs emitted by D2's go-pdf/fpdf writer. It intentionally is not a general PDF parser.

func InspectD2PDF(content []byte) (*PDFInspection, error)

type PDFPage ¶ added in v0.9.0

type PDFPage struct {
	ObjectNumber  int
	Width, Height float64
	ExternalLinks []string
	InternalLinks int
}

type PagedImageComparison ¶ added in v0.9.0

type PagedImageComparison struct {
	Page   int
	Result *imagediff.Result
}

PagedImageComparison retains the first embedded-image mismatch so callers can write its self-contained HTML diagnostics.

func ComparePDFImages(pdfContent []byte, expectedPNGs [][]byte, options imagediff.Options) (*PagedImageComparison, error)

func ComparePPTXImages(pptxContent []byte, expectedPNGs [][]byte, options imagediff.Options) (*PagedImageComparison, error)
