Hi Agama,

Many thanks for the reply. I have just tried that on an image I know is corrupt and it does the same, just hangs and uses 100% of one of my cpu's. Had to kill the process.

Doesnt throw an error or anything!

I have the latest build so its all up to date.

Any other ideas what I could possibly try?

thanks for your help.

mike

          echo zero image 
       fi
   done

Hi Mirni,

Thanks for the response. That has confused me massively! Smilie

So by looking at this it looks like it finds images that are 0x0 pixels and echos...?

How can I incorprate my -trim syntax in to this and make it recursive on a directory?

Sorry if I sound stupid! Smilie

cheers,

Mike

NAME
pamdice - slice a Netpbm image into many horizontally and/or vertically SYNOPSIS
pamslice -outstem=filenamestem [-width=width] [-height=height] [-verbose] [filename] You can use the minimum unique abbreviation of the options. You can use two hyphens instead of one. You can separate an option name from its value with white space instead of an equals sign. DESCRIPTION
Reads a PAM, PBM, PGM, or PPM image as input. Splits it horizontally and/or vertically into equal size pieces and writes them into sepa- rate files as the same kind of image. See the -outstem option for information on naming of the output files. The -width and -height options determine the size of the output pieces. pnmcat can rejoin the images. OPTIONS
-outstem=filenamestem This option determines the names of the output files. Each output file is named filenamestem_y_x.type where filenamestem is the value of the -outstem option, x and y are the horizontal and vertical locations, respectively, in the input image of the output image, zero being the leftmost and top, and type is .pbm, .pgm, .ppm, or .pam, depending on the type of image. -width=width gives the width in pixels of the output images. The rightmost pieces are smaller than this if the input image is not a multiple of width pixels wide. -height=height gives the height in pixels of the output images. The bottom pieces are smaller than this if the input image is not a multiple of height pixels high. -verbose Print information about the processing to Standard Error. SEE ALSO
