set_posfig_dim - change defaut transformation for exporting in postscript

Calling Sequence

set_posfig_dim(w,h)

set_posfig_dim(0,0)

Parameters

• w : graphic figure width, number of pixels
• h : graphic figure height, number of pixels

Description

set_posfig_dim(w,h) set the coordinates transformation to be used when exporting a graphic window in postscript. The graphic figure zoomed with ratios w/<graphic figure width> horizontally and h/<graphic figure height> vertically.

This function is particularily useful when one wants an export a graphic figure exactly as it is shown on the screen. For that w and h has to be set respectively to <graphic figure width> and <graphic figure height>

set_posfig_dim(0,0) resets the default values: w=600 , h=424 .

Examples

    // make a figure with a specific shape 
    f=scf(0);f.figure_size=[800,300];
    plot2d()
    set_posfig_dim(f.figure_size(1),f.figure_size(2))
    filename='foo'; // ! no extension
    xs2ps(0,filename)
    //add the Postscript file header and create <filename>.eps file
    if MSDOS then
      unix_s(pathconvert('""'+WSCI+'/bin/BEpsf'+'""',%f)+' -p ' +filename)
    else
      unix_s(pathconvert('SCI/bin/BEpsf',%f)+' -p ' +filename)
    end
