Imagemagick on linux to convert EMF to PNG

Question

I am trying to convert an image in EMF format to PNG using Imagemagick on Red Hat Enterprise Linux Server release 5.5 (Tikanga), but I am running into the following error:

convert: no decode delegate for this image format `thumbnail.emf' @ error/constitute.c/ReadImage/550. convert: no images defined `1.png' @ error/convert.c/ConvertImageCommand/3068.

How might I fix this?

Try libreoffice first and then imagemagick as I wrote in this answer. – Coldiron

Install libreoffice and run this command on the folder where your emf files are located:

libreoffice --headless --convert-to png *.emf

Another way is to use inkscape:

inkscape -o file.png source.emf

See inkscape --help for more export options (area to export, dpi, image resolution, background color etc).

Not imagemagick, but it works. Can also do svg, (e)ps, pdf and LaTeX. – Flounce

This worked for me in spite of @ArnaudWeil's comment. – Auxin

Maybe MS does put whatever they want into EMF... "** (inkscape:10912): WARNING **: Specified document image5.emf cannot be opened (does not exist or not a valid SVG file)" – Vergne

inkspace -o file.png -d 300 source.emf (options have changed) – Lamarckism

Answer 4

libreoffce will output a png that is a different size than the original image. I used inkscape instead. The arguments have changed (works as of 2024):

inkscape -z -f image16.emf -e image16.png
