Thanks!!!

Two issues regarding the latest laplacian script.

1. The download link still points to gradient script.

2. I managed to "steal" the laplacian script, but I don't know how to use
it. E.g., how to apply the "Laplacian 1" convolution? Based on the help
text, I thought it should be:

 $ laplacian -f 1 zelda3.jpg zelda3.l3.jpg
 
but, this is what I get:

2D Laplacian Kernel
0         -1        0         
-1        4         -1        
0         -1        0         

2D Final Laplacian Kernel
0         -1.000    0         
-1.000    4.000     -1.000    
0         -1.000    0         

IM Final Laplacian Kernel
0,-1.000,0,-1.000,4.000,-1.000,0,-1.000,0

convert: unable to open image `/laplacian_7058.mpc': Permission denied.

--- FILE zelda3.jpg DOES NOT EXIST OR IS NOT AN ORDINARY FILE, NOT READABLE OR HAS ZERO SIZE ---


laplacian:

USAGE: laplacian [-f filter] [t thresh] [-m mix] infile outfile
USAGE: laplacian . . .

but I have the zelda3.jpg:

$ ls -lgG zelda3.jpg
-rw------- 1 17145 09-23 17:43 zelda3.jpg

Please help. 

thanks
