PSIMAGE - PostScript IMAGE plot of a uniformly-sampled function f(x1,x2) psimage n1= [optional parameters] postscriptfile Required Parameters: n1 number of samples in 1st (fast) dimension Optional Parameters: d1=1.0 sampling interval in 1st dimension f1=0.0 first sample in 1st dimension n2=all number of samples in 2nd (slow) dimension d2=1.0 sampling interval in 2nd dimension f2=0.0 first sample in 2nd dimension perc=100.0 percentile used to determine clip clip=(perc percentile) clip used to determine bclip and wclip bperc=perc percentile for determining black clip value wperc=100.0-perc percentile for determining white clip value bclip=clip data values outside of [bclip,wclip] are clipped wclip=-clip data values outside of [bclip,wclip] are clipped bclip and wclip will be set to be inside [lbeg,lend] if lbeg and/or lend are supplied threecolor=1 supply 3 color values instead of only two, using not only black and white, but f.e. red, green and blue brgb=0.0,0.0,0.0 red, green, blue values corresponding to black grgb=1.0,1.0,1.0 red, green, blue values corresponding to grey wrgb=1.0,1.0,1.0 red, green, blue values corresponding to white bhls=0.0,0.0,0.0 hue, lightness, saturation corresponding to black ghls=0.0,1.0,0.0 hue, lightness, saturation corresponding to grey whls=0.0,1.0,0.0 hue, lightness, saturation corresponding to white bps=12 bits per sample for color plots, either 12 or 24 d1s=1.0 factor by which to scale d1 before imaging d2s=1.0 factor by which to scale d2 before imaging verbose=1 =1 for info printed on stderr (0 for no info) xbox=1.5 offset in inches of left side of axes box ybox=1.5 offset in inches of bottom side of axes box width=6.0 width in inches of axes box height=8.0 height in inches of axes box x1beg=x1min value at which axis 1 begins x1end=x1max value at which axis 1 ends d1num=0.0 numbered tic interval on axis 1 (0.0 for automatic) f1num=x1min first numbered tic on axis 1 (used if d1num not 0.0) n1tic=1 number of tics per numbered tic on axis 1 grid1=none grid lines on axis 1 - none, dot, dash, or solid label1= label on axis 1 x2beg=x2min value at which axis 2 begins x2end=x2max value at which axis 2 ends d2num=0.0 numbered tic interval on axis 2 (0.0 for automatic) f2num=x2min first numbered tic on axis 2 (used if d2num not 0.0) n2tic=1 number of tics per numbered tic on axis 2 grid2=none grid lines on axis 2 - none, dot, dash, or solid label2= label on axis 2 labelfont=Helvetica font name for axes labels labelsize=18 font size for axes labels title= title of plot titlefont=Helvetica-Bold font name for title titlesize=24 font size for title titlecolor=black color of title axescolor=black color of axes gridcolor=black color of grid axeswidth=1 width (in points) of axes ticwidth=axeswidth width (in points) of tic marks gridwidth=axeswidth width (in points) of grid lines style=seismic normal (axis 1 horizontal, axis 2 vertical) or seismic (axis 1 vertical, axis 2 horizontal) legend=0 =1 display the color scale lnice=0 =1 nice legend arrangement (overrides ybox,lx,width,height parameters) lstyle=vertleft Vertical, axis label on left side =vertright (Vertical, axis label on right side) =horibottom (Horizontal, axis label on bottom) units= unit label for legend legendfont=times_roman10 font name for title following are defaults for lstyle=0.

A "vector" of curve files and curve colors may be specified as curvefile=file1,file2,etc. and curvecolor=color1,color2,etc, and the number of pairs of values in each file as npair=npair1,npair2,... . You may eliminate the blocky appearance of psimages by adjusting the d1s= and d2s= parameters, so that psimages appear similar to ximages. All color specifications may also be made in X Window style Hex format example: axescolor=#255 Some example colormap settings: red white blue: wrgb=1.0,0,0 grgb=1.0,1.0,1.0 brgb=0,0,1.0 white red blue: wrgb=1.0,1.0,1.0 grgb=1.0,0.0,0.0 brgb=0,0,1.0 blue red white: wrgb=0.0,0.0,1.0 grgb=1.0,0.0,0.0 brgb=1.0,1.0,1.0 red green blue: wrgb=1.0,0,0 grgb=0,1.0,0 brgb=0,0,1.0 orange light-blue green: wrgb=1.0,.5,0 grgb=0,.7,1.0 brgb=0,1.0,0 red light-blue dark blue: wrgb=0.0,0,1.0 grgb=0,1.0,1.0 brgb=0,0,1.0 AUTHOR: Dave Hale, Colorado School of Mines, 05/29/90 MODIFIED: Craig Artley, Colorado School of Mines, 08/30/91 BoundingBox moved to top of PostScript output MODIFIED: Craig Artley, Colorado School of Mines, 12/16/93 Added color options (Courtesy of Dave Hale, Advance Geophysical).
