The routine gGetPicture() interprets a metafile produced by the gSavdra() or gSavpic() generator. Only the information contained within each picture segment is output. gGetPicture() ignores any information that records the settings of the line and character attributes that were current when each picture segment was opened.
The metafile should be opened prior to calling this routine using the function gFopen(), with the file pointer or unit number passed as appropriate.
A call to gGetPicture() does not affect any of the current settings (line attributes, character attributes, transformation, etc).
