mg_psfrag.pro

includes main-level program

Routines

top mg_psfrag

mg_psfrag [, filename] [, output_filename] [, xsize=float] [, ysize=float] [, /inches]

Processes specially formatted text output in .ps and .eps files with LaTeX.

Keyword values to graphics command expecting strings to output as text can be set to values like:

  \tex[<posn>][<psposn>][<scale>][<rot>]{LATEX text}

where posn and psposn are positions and can be one of the following:

  bl = bottom left
  c = center
  t = top
  r = right
  B = baseline

The <scale> parameter is used in place of the CHARSIZE keyword, which will be ignored.

This routine requires sed, latex, and dvips to be installed and available in the system path. Also, ps2eps is needed to if the file to be created is an .eps file.

Parameters

filename in optional type=string default=idl.ps

filename of PS or EPS file to substitue text in

output_filename in optional type=string default=filename

filename of output PS file

Keywords

xsize in optional type=float default=17.78: width of graphic in cm
ysize in optional type=float default=12.7: height of graphic in cm
inches in optional type=boolean: set to specify sizes in inches instead of centimeters

Examples

See the main-level program at the end of this file. To run it:

  IDL> .run mg_psfrag

Produce a .ps or .eps file with text output inside a \tex{}. This text will be translated by LaTeX:

  set_plot, 'ps'
  device, filename='figure.eps', /times, /encapsulated
  xyouts, 3., 5., '\tex[bl][bl][3.0]{Sun symbol: $M_\odot$}', font=0
  plot, findgen(10), /nodata
  device, /close

Note: the entire text must be the \tex{} phrase, it cannot be combined with normal output like:

  xyouts, 3., 5., 'Sun symbol: \tex[bl][bl][3.0]{$M_\odot$}', font=0

Then run MG_PSFRAG on the output:

  mg_psfrag, 'figure.eps', 'figure-subs.eps'

This should produce output like:
