You are correct. WMF is a vector format. In fact the scale information is stored in the WMF header records as 'number of vector units' per inch. This scale is used later in the conversion of pen width (which is specified in vector units) to points. I don't remember the details very well (I wrote a module for converting data from WMF to MIF format several years ago), but WMF has several other device control data besides the usual vector and font stuff.
Hope this helps. Srini _____________________________________________ Ponniah Srinivasan CertainTech, Inc.
