When printing an invoice with an iban qrcode using l10n_ch module, a little ch flag appears in the center of the qr code. When odoo is started from elsewhere than the root of the odoo code, the flag does not appear. The cause is that a relative path is used to find the flag image. With this commit, an absolute path is computed to find the flag. closes odoo/odoo#61048 X-original-commit: d33785032b1ca2c6e1d4ade7e174d024fae9a151 Signed-off-by: oco-odoo <oco-odoo@users.noreply.github.com> Signed-off-by: Christophe Monniez (moc) <moc@odoo.com>
