`set-map-mode`

The mapping mode of the device context defines the unit of measurement used to convert logical units to device units. Text drawing is not handled consistently with the mapping mode on some platforms. (Setting the user scale does scale the text appropriately; see set-user-scale.) Also, the mapping mode is currently ignored for PostScript output.

The mapping mode can be one of the following:

wx:const-mm-twips -- each logical unit is 1/20 of a point, or 1/1440 of an inch
wx:const-mm-points -- each logical unit is a point, or 1/72 of an inch
wx:const-mm-metric -- each logical unit is 1 millimeter
wx:const-mm-lometric - each logical unit is 1/10 of a millimeter
wx:const-mm-text -- each logical unit is 1 pixel

Restrictions on the magnitude of drawing coordinates are described with wx:dc%.
