Margin 0 error code is output in png files.

[tuncaybahadir]

First of all, thank you for your near-perfect package.

The subject was opened before, but the subject was suspended because the friend who opened it moved to Mars.

The problem is, when margin is given as 0 when generating qr code in png format, the qr generated is incorrect. In the qr code, white dots are formed in black colors on the left edge. When creating a QR code, the location of the white dots changes according to the given text. Many devices cannot read the qr code due to white dots. When the margin is given at 1 and above, the error disappears.

I am sending details about the error below.

Tools Used;

php 8.4
bacon/bacon-qr-code 3.0

`

  new ImageRenderer(
        new RendererStyle(400, 0),
        new ImagickImageBackEnd()
    );

    $writer = new Writer($renderer);
    $writer->writeFile('Quar package create qr code', 'bacon.png');

`

When we give a value of margin 1 or above, no problem occurs.

`

  new ImageRenderer(
        new RendererStyle(400, 1),
        new ImagickImageBackEnd()
    );

    $writer = new Writer($renderer);
    $writer->writeFile('Quar package create qr code', 'bacon.png');

I looked into this, and I'd file this under just another IMagick rendering issue, of which there are already plenty in that library. I'd highly recommend to just use the SVG renderer, there's not really any good reason nowadays not to :)

Thank you for your valuable reply. I use svg in many processes. But I know that I need to use png format when adding an image on qr code. How can I do this process in svg?

You could use something like php-svg.

It has a basic rasterizer, which will generate a gd object, though that's quite resource intensive.

What I'd do is load the SVG in it, and just add an <image/> tag with an image as data URL included.
