anyone know how I can fix this install error?

Fred, could you have two ghostscript programs installed?

Not that I am aware. But I guess it is possible if they are not in the same directory.

freds-mac-mini:/usr/local/bin fred$ ls -al gs*
-rwxr-xr-x 1 root wheel 10408028 Feb 25 2008 gs
-rwxr-xr-x 1 root wheel 376 Feb 25 2008 gsbj

No need for a restart. The problem appears to be a Ghostscript installation problem. You can test by running Ghostscript directly from the command line.

• convert logo: logo.ps
  "gsc" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=0 "-sDEVICE=pam" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" -g121x87 "-sOutputFile=logo.pam" "logo.ps"

convert logo: logo.ps

"gsc" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=0 "-sDEVICE=pam" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" -g121x87 "-sOutputFile=logo.pam" "logo.ps"

Ok, now try the pnmraw device. It is generally available to all Ghostscript installations. It appears that your problem is with Ghostscript, not ImageMagick.

[fmw42]

thanks. I tend to agree that the problem is with Ghostscript. I will try your suggestion as soon as I can.

This morning I tried:

convert rose: rose.pdf
convert rose.pdf rose.png

which worked fine.

But

convert rose: rose.ps
convert rose.ps rose.png

Does this tell you anything further.

This is very strange:

This works fine to create a ps file via a pdf file and then convert the ps to png.
convert logo: logo.pdf
convert logo.pdf logo.ps
convert logo.ps logo.png

But if I try to convert directly to ps and then convert that to png it fails. What is the significance of this?
convert logo: logo.ps
convert logo.ps logo.png

Error: /invalidfont in /findfont
Operand stack:
Times-Roman

...
as per my message above.

Also this works:

convert logo: logo.pdf
convert logo.pdf logo.ps
"gsc" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=0 "-sDEVICE=pnmraw" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" -g121x87 "-sOutputFile=logo.pnm" "logo.ps"

But this fails:

convert logo: logo.ps
freds-mac-mini:~ fred$ "gsc" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=0 "-sDEVICE=pnmraw" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" -g121x87 "-sOutputFile=logo.pnm" "logo.ps"
Error: /invalidfont in /findfont
Operand stack:

...
etc as per my post above.


Do I need to reinstall Ghostscript? Or is this a font issue? If I need to re-install GS, what version do you recommend? What are the IM folks using currently? (Ghostscript is now up to 8.64)
