Imagemagick: Producing PDF output inserts weird 'Producer' metadata

[KurtPfeifle]

When IM7 produces PDF output, it inserts weird Producer values (this metadata is optional) into the PDF metadata (it uses the path to ImageMagick's local index.html documentation file). While this issue is not too important, it still looks very weird.

Suggestions:

1. Insert a part of the string which is printed by the magick -version command -- for example insert ImageMagick 7.0.7-29 Q16 x86_64 20180324 http://www.imagemagick.org.

2. Consider to also fill the (optional) Creator: field in the PDF metadata.

^{According to the PDF-1.7 spec (table 317, page 550):}

1. ^{Producer is meant to name the product that converted a document from an originally different format to PDF.}
2. ^{Creator is meant to name the product that created the original document before it was converted to PDF.}

Steps to reproduce

ImageMagick version:

magick -version Version: ImageMagick 7.0.7-29 Q16 x86_64 20180324 http://www.imagemagick.org Copyright: © 1999-2018 ImageMagick Studio LLC License: http://www.imagemagick.org/script/license.php Features: Cipher DPC HDRI OpenMP Delegates (built-in): bzlib cairo djvu fftw fontconfig freetype gslib gvc heic jbig \ jng jp2 jpeg lcms lqr lzma openexr pangocairo png ps raw rsvg tiff webp wmf \ x xml zlib

Create a PDF with ImageMagick:

magick logo: logo.pdf

Check the PDF properties:

pdfinfo logo.pdf | grep Producer Producer: /usr/local/share/doc/ImageMagick-7//index.html

Update

Just noticed: IM v6 (6.9.9-26) uses the same way to name "Producer" metadata...
