Hello ! I have a question about maxsize, minsize attribute. There is a description as follows: The minsize and maxsize attributes limit the amount of stretching (in either direction). These two attributes are given as multipliers of the operator's normal size in the direction or directions of stretching, or as absolute sizes using units. For example, if a character has maxsize="3", then it can grow to be no more than three times its normal (unstretched) size. (MathML2.0 spec, "3.2.5.8 Stretching of operators, fences and accents") It says that "<mo maxsize/minize=3>" specifies to render the size of a operator as 300% of unstretched size of the operator. In contrast, samples in MathML test suite seem to imply that "<mo maxsize/minize=3>" specifies to render the size of a operator as 300% of "stretched" size of the operator. For example, In the case of Presentation/TokenElements/mo/moSminmax20 <mstyle minsize='1cm' maxsize='3cm'> <mrow> <mo>(</mo> <mfrac> <mi>y</mi> <mi>z</mi> </mfrac> <mo maxsize='25%'>)</mo> --- (1) <mo>+</mo> <mo minsize='225%'>(</mo> --- (2) <mfrac> <mi>y</mi> <mi>z</mi> </mfrac> <mo maxsize='infinity'>)</mo> </mrow> </mstyle> </math> >From the sample rendering, the size of parenthesis (1) seems to be 25% of the height of a fraction, and the size of parenthesis (2) seems to be 225% of the height of a fraction. The height of these parentheses are not 25% nor 225% of "unstretchd" size. Is there any misunderstanding ? Tokushige Kobayashi Antenna House, Inc.
