Hi,

there is a problem if I convert from ps (eps) to pdf.
At the version 6.4.2 it works well. The pdf is well and I am able to mark text in it.
With the version 6.7.3-2 the conversion works too, but the result is a bitmap pdf. The size of the file is for the factor 10 bigger.
Version 6.4.2:

Code: Select all

convert -verbose 00976451.eps.ps test.pdf

"gs" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=0 "-sDEVICE=pam" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" -g128x142  "-sOutputFile=/tmp/magick-XXI7ZoFn" "-f/tmp/magick-XXD8ZMaF" "-f/tmp/magick-XXLJKlGW"
/tmp/magick-XXI7ZoFn PNM 128x142 128x142+0+0 8-bit ColorSeparation DirectClass 71.1kb
00976451.eps.ps PS 128x142 128x142+0+0 16-bit ColorSeparation DirectClass 71.1kb
"gs" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=0 "-sDEVICE=pdfwrite" "-sOutputFile=/tmp/magick-XXBROoY6" "-f/tmp/magick-XXTwlvTi"

Version 6.7.3-2:

Code: Select all

convert -verbose -format pdf 00976451.eps.ps test.pdf

"gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pam" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" -g128x142  "-sOutputFile=/tmp/magick-M9IGiCcL-%08d" "-f/tmp/magick-8vmo9Cu4" "-f/tmp/magick-tKSJsJMn"
/tmp/magick-M9IGiCcL-00000001 PAM 128x142 128x142+0+0 8-bit ColorSeparation DirectClass 72.8KB 0.000u 0:00.000
00976451.eps.ps PS 128x142 128x142+0+0 16-bit ColorSeparation DirectClass 72.8KB 0.000u 0:00.000

At the version 6.7.3 the second step is missing (gs ...-sDEVICE=pdfwrite ...).

Is there a mistake by me ??

It looks like the delegates are attempting to 'short-circuit' as you don't modify the image in memory.

Add a -taint between the read of the PS and the write of the PDF.

See IM Examples, File Handling, Delegates for more detail.

No change:

Code: Select all

convert -verbose 00976451.eps.ps -taint pdf:test.pdf
"gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pam" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" -g128x142  "-sOutputFile=/tmp/magick-h0HZ3vA2-%08d" "-f/tmp/magick-CBWolTSC" "-f/tmp/magick-nv9u2lbd"

Try this command:

convert -verbose 00976451.eps.ps -define delegate:bimodal=true test.pdf

Bimodal delegate support is seldom used and it was affecting performance so we made it an option.

It works. This is the right moment to go into the weekend

Thanks a lot

P.S Where can I find some documentation about the Option bimodal

See the PDF format @ http://www.imagemagick.org/script/formats.php. It simply says: To specify direct conversion from Postscript to PDF, use -define delegate:bimodel=true.

Sounds to me that this bimodel is better done simply by forgetting IM enterirely have just using ghostscript directly.

triumir Can you give the actual delegate command that the bimodel delegate generations in your example.
