EMUs measuring unit

EMUs are the measuring unit to add contents in MS PowerPoint presentations.

"EMU" is the acronym for English Metric Unit. EMUs are equivalent to 1/360,000 of a centimeter, 1/914,400 inches or 1/12,700 points.

phppptx includes a method to transform EMUs from and to other units: cm, in, pt, px.

// transform cm to emu
$value = OOXMLResources::transformUnits('2cm', 'emu');

// transform pt to emu
$value = OOXMLResources::transformUnits('14pt', 'emu');

// transform emu to pt
$value = OOXMLResources::transformUnits('32400emu', 'pt');
