Re: [ferret_users] How to remove the white spots from the postscriptfigures?

It can't tell from these commands but it seems to me that probably what you are seeing is what others have been writing about as "odd lines" on the postscript.  This is an artifact of the graphics package.  On a plot of data that has a very fine grid this might not be distinguished as lines but might look like other wiggly shapes.  This is what is being discusses in this thread:

Or depending on what you need the image for, making a gif image, by starting Ferret in the -gif mode, will also produce an image without the appearance of this effect.

Hello Ansley,
Please see my code below.

SET MEMORY/SIZ=416  ! Fix insufficient memory issue.

 set mode meta ! for figure saving
 FILL/L=1 CLIM_SST[i=1:8192:10,j=1:4096:10]!plot sst variable.
 Go fland
 ppl clsplt !close the plot.
 sp Fprint -o "/DATA/month01_combined_sst.ps"
 metafile.plt !save ps file.

Since the file size is very large I could not attach the ps file.

Thanks in advancce,

We need more information.  Do you think you are seeing the "white lines"
that have been discussed in this Users List, such as this thread,
(where Roman has attached a figure - see if your case is similar)

If you are seeing something else, then are you closing the plot before
converting it to postscript

    ppl clsplt
    sp Fprint -o file.ps metafile.plt

Hello All,
When I created the postscript figures using the following command I
got white spots in the figures.

sp Fprint -o file.ps metafile.plt

I even converted the ps files to pdf and eps also, but the white spots
still remain there.

Can somebody suggest me some useful tips to remove these from the

Thanks in advance,
