OpenType outlines not the same as Type 1? (Gill and Minion)

Hello,

one of our designers was tasked with switching existing layouts and designs from using PostScript Type 1 fonts to OpenType fonts. To my surprise he reported a difference between the fonts. I have attached an image that clearly shows the difference:

type1-vs-opentype.png

The ones on the left are the PostScript Type 1 versions of Gill Sans and Minion, the ones on the right are the OpenType versions of Gill Sans Std and Minion Pro. Aren't these supposed to be the same? It was my understanding thatOpenType fonts can contain the same outlines as the PostScript Type 1 fonts.

Is there a recommended way of moving from PostScript Type 1 to OpenType?

Thank you!

    The outlines of Gill Sans seem like they haven't change. The one difference I see is the position of the first baseline. This happens because Type 1 fonts don't have a OS/2 table which holds vertical metrics values. In InDesign, to control the position of the first baseline and the baseline grid, use the 'Baseline Options' pane of the 'Text Frame Options' dialog.

    As for Minion, design and spacing changes were made during the conversion to OpenType, as documented in this page http://www.adobe.com/type/opentype/T1_to_OTF_FAQ.htm
