IMG_PLOT

Name


      IMG_PLOT

Purpose


      Plot on a 24-bit image without using X windows.

Category


Calling Sequence


      img2 = img_plot(img1,x,y)

Inputs


      img1 = Original image. in
      x,y = x,y arrays to plot. in

Keyword Parameters


Keywords


        COLOR=clr Plot color.
          May also be a 3 element array: [R,G,B].
        THICK=thk Curve thickness *def=!p.thickness).
        CHARSIZE=csz Text size (def=!p.charsize).
        CHARTHICK=cthk Text Thickness (def=!p.charthick).
        POSITION=pos plot position in normalized coordinates.
        /DEVICE means pos is in device coordinates.
        /ANTIALIASED means do antialiasing. A bit slower.
        ERROR=err Error flag: 0=ok.

Outputs


      img2 = returned image. out

Common Blocks


Notes


      Note: uses Z buffer, save a copy before if using Z.
        XTHICK and YTHICK control the thickness of the axes
        but either one will control both. They are not
        independent in this routine. Also antialiased
        LINESTYLE will not exactly match normal linestyle.
