Don't know why this didn't show up yesterday. imagedestroy has done nothing starting with Php 8.0.0, and will be deprecated in Php 8.5. Perhaps you can skip it for Php 8+. You call it 21 different times across 6 modules:

• lib/Cpdf
• src/Adapter/CPDF
• src/Adapter/GD
• src/Adapter/PDFLib
• src/Renderer/AbstractRenderer
• php-svg-lib/src/svg/Surface
