Incorrect SVG rendering in TCPDF since version 6.8.2 #834
Description
Description: I noticed that SVG files are no longer rendered correctly starting with TCPDF version 6.8.2. In my test case, a simple green downward arrow SVG is displayed properly in version 6.6.5, but gets distorted in 6.8.2 and 6.10.0.
Steps to reproduce: Use the following minimal PHP script:
AddPage(); $pdf->ImageSVG('@' . $svg, 15, 30, 50, 50, '', '', '', 0, false); $pdf->Output('php://stdout', 'I'); php testpgm.php icon.svg > output.pdf Expected result: A clean green downward arrow. Actual result: Starting with TCPDF 6.8.2, the SVG is rendered incorrectly (see comparison below). Comparison: ✅ TCPDF 6.6.5 → correct rendering ❌ TCPDF 6.8.2 / 6.10.0 → distorted rendering Screenshots:
❌ TCPDF 6.8.2 / 6.10.0 → distorted rendering
✅ TCPDF 6.6.5 → correct rendering
I am not so sure working here in GitHub, but I think I managed to include the SVG as well. I also had the issue with other SVG files (for the record: I use an extension within typo3 CMS that relies on tcpdf). I managed to locate the issue down to tcpdf and with a bit of AI help generated this testcase.
