Low quality QR codes

[ianzren]

Describe the bug Not sure if this is a bug or intended but noticed that the generated QR code is of much lower quality than the example in the docs. I ran the "simplest" example given locally which produced this pdf.

Docs

The generated PDF looks high quality in Chrome and Firefox but low quality in Safari. Physically printing the PDF also always returns a low quality qr code.

Simplest example code

func main() {
    m := GetMaroto()
    document, err := m.Generate()
    if err != nil {
        log.Fatal(err)
    }

    err = document.Save("./cmd/ian/ian.pdf")
    if err != nil {
        log.Fatal(err)
    }
}

func GetMaroto() core.Maroto {
    m := maroto.New()

    m.AddRow(20,
        code.NewBarCol(4, "barcode"),
        code.NewMatrixCol(4, "matrixcode"),
        code.NewQrCol(4, "qrcode"),
    )

    m.AddRow(10, col.New(12))

    m.AddRow(20,
        image.NewFromFileCol(4, "docs/assets/images/biplane.jpg"),
        signature.NewCol(4, "signature"),
        text.NewCol(4, "text"),
    )

    m.AddRow(10, col.New(12))

    m.AddRow(20, line.NewCol(12))

    return m
}

I don't know what this can be. But I know that there are printed codes that are in good quality, since maroto is used in production envs world wide.

I don't know if this is relevant information, but testing in the Debiam document viewer, I had the same result as you, but when zooming in on the image the quality seems to have remained as in the example in the documentation, this low quality is not related to some configuration in the pdf reader? Unfortunately I don't have access to a printer or safari to validate this possibility.

Since there is no response after 2 weeks, and we know that the QRCodes and Barcodes are working in other platforms I will close this.
