Hello ConTeXist.

I would like use modes alternative to change of image dimensions in different documents (presentation or print version). Compilation in ConTeXt TeXLive 2012 version will compile without error, but without visual effect. Compilation with the standalone version fails. What is problem or eventually. how to solve my problem another way. The \doifmodeelse command isn’t expandable and can’t be used in this form.

Thanks Jaroslav Hajtmar

Here is my minimal example:

\enablemode[presentation]

\def\alternativewidth#1#2{ \doifmodeelse{presentation} {width=#1} {width=#2} }

\useexternalfigure[COW][cow.pdf][height=5cm, \alternativewidth{3cm}{5cm}] \startmode[presentation] \useexternalfigure[COW][cow.pdf][height=5cm,width=3cm] \stopmode

\startnotemode[presentation] \useexternalfigure[COW][cow.pdf][height=5cm,width=5cm] \stopnotmode

or

\startmode[presentation] \definemeasure[alternativewidth][3cm] \stopmode

\startnotmode[presentation] \definemeasure[alternativewidth][5cm] \stopnotmode

\useexternalfigure[COW][cow.pdf][height=5cm,width=\measure{alternativewidth}]
