any news on this - I'd still be very happy if this feature would be implemented

@dlemstra did you find a way to automate the limiting of the density with which the image is read to the max. possible value?

e.g. convert -units PixelsPerInch -density max %1 -resize 3307x -density 300 %1.jpg

For me the two emf seem to have the same content (drawing wise) - same size (lenght x width), different file size (the bigger one works).

The question is how should I know that is an appropriate density for each file. The conversion should be fully automated in background before uploading the ...

Thanks! That does work.

The output in the end should always be 3307x* with 300 dpi for optimal printing. The input files do not always have the same size. Now if I hardcode "-density 10" I might reduce the image size to much and would then upscale the image. Which will not return good results.

I usually don't work with linux so just for testing I downloaded a Ubuntu virtualbox image and installed ImageMagick.

Unfortunately I couldn't find a delegate library for EMF. Is there actually one for Linux?

I was able to create a pdf from the emf using unoconv though - still not what I want ...

Thanks I changed my script and also updated to the latest version

I appreciate your comments but they do not provide anything pointing to an solution.

Did you download the sample and verify your recommendations work on your system?

Actually it does not matter what parameter I use. Also in a very Basic Syntax "convert <emf> <jpg>" I do get this error.

It must bei relativ to the files somehow. Its not the geometry size as files containing the same geometry plus additional geometris work.

Hi,

I try to convert EMF to JPG format. The vector graphics in the EMF files are rather big so I downsize the files using the command
convert -geometry "3307x2244" -units PixelsPerInch -compress "JPEG" %1 -density 300 %1.jpg

Output:
convert.exe: UnableToReadImageData `00010003_1247.emf' @ error ...

the file is generated by an adobe flash app and should be imported into SAP

the problem is I could not get flash to save the bitmap in any other format and import into SAP does not work properly unless the bitmap is 8bit only

thanks - useful hint but did not solve the problem

seems its doing something
convert img.bmp -type palette -depth 8 img_new.bmp

filesize is reduced from 880k to 13k, image looks like it should BUT its still 32bit and not 8
convert img.bmp -colorspace Gray -type palette -depth 8 img_new.bmp does ...

Trying to convert a 24/32bit bmp or jpg to a 8bit bmp using ImageMagick-6.7.6-4-Q16-windows-x64-static with the following commands fail:
convert img.bmp -depth 8 img_new.bmp or
convert img.jpg -depth 8 img_new.bmp

conversion of 8bit bmp or jpg into 8bit bmp fails as well

conversion of 24bit bmp ...
