This fixes and avoids "error: call to 'abs' is ambiguous".

Thanks for the PR. Makes sens to me. But I have a question: where did you see this error message? (platform/compiler/version?)

platform: Ubuntu 22.10
compiler: Android SDK 33, Android NDK r19c(19.2.5345600) / r20c(20.1.5948944)
version: 1.4.0

I received that error message when I built LibreOffice with zxing-cpp.
However, that error occurred only in building PDFEncoder.cpp.
