php 8.1 compatibility with method _addStringAsSVGImage()

[schplurtz]

Hi,

As DW Igor is approaching, I try the a2s plugin with Igor RC 2 and PHP 8.1

When I want to export to odt a DW page with an SVG image made by a2s, it fails. with Error: Non-static method ODTImage::addStringAsSVGImage() cannot be called statically error.

Is it me who is not using the right method in the a2s renderer, or is this a bug in the odt plugin ?

Just below, the error stack trace and the code I use in the a2s plugin.
