- Is there a bug in PBMPLUS for VMS, as found on the VMSNET.SOURCES archives?
- After copying the saveset, unpacking the files and doing @SETUP I want to
- convert color PCX files to readable PBM files (I know that the color information
- is lost, that is actually useful in this application). On a Unix machines I
- can use something like
- "pcxtoppm file.pcx | ppmtopgm | pgmtopbm -threshold | pnmnoraw > file.pbm"
- The corresponding sequence under VMS should be "@p2b file", where p2b.com is:
-
- $! pcx -> ppm
- $ define/user sys$output 'p1'.ppm
- $ pcxtoppm 'p1'.pcx
- $! ppm -> pgm
- $ define/user sys$output 'p1'.pgm
- $ ppmtopgm 'p1'.ppm
- $! pgm -> pbm
- $ define/user sys$output 'p1'.pbm_raw
- $ pgmtopbm -threshold 'p1'.pgm
- $! pbm -> pbm (ASCII)
- $ define/user sys$output 'p1'.pbm
- $ pnmnoraw 'p1'.pbm_raw
-
- The first step works fine, but then the ppmtopgm step breaks down and I get
- a file with 3 lines of header and no data... What am I doing wrong?
