◆ BOOST_AUTO_TEST_CASE() [6/9]

BOOST_AUTO_TEST_CASE ( PPIFromNonIntegerPixelsPerCm )

Verify PPI is computed without integer truncation when pixels/cm is non-integer.

PNG stores resolution as pixels-per-meter (e.g. 3780 PPM for ~96 DPI). wxWidgets converts to pixels-per-cm as a string ("37.8"). The old code used GetOptionInt() which truncated "37.8" to 37 before multiplying by 2.54, giving 94 instead of the correct 96. This tests that the full precision path is used.
