Legacy ImageMagick Discussions Archive

I just installed ImageMagick because I need to convert a multi-page PDF into individual PNG files. Right now using GIMP of PS batch commands isn't doing the trick. I'm new to IM and I noticed that on windows, the convert command is for drive management. Is there a different exe windows users run for this?

I also would like to set the destination resolution, so after reading quite a few posts, I amg guessing that my parameters will be

something.exe -density 300 file.pdf -scale 825x1125 .\test\output-%d.png

would this be correct?

edit: just to add, I have installed ImageMagick-7.0.4-5-Q16-x64-dll.exe
and have run the test:
magick logo: logo.gif
magick identify logo.gif
magick display logo.gif
everything seems to be ok

try
But be sure you are using the IM convert.exe and not the Window convert.exe. Many IM Windows users rename the IM convert.exe to something like IMconvert.exe.

What is your IM version? If you are using IM 7, then change convert.exe to magick.exe

The only binaries that I have in the folder are:
dcraw.exe
ffmpeg.exe
hp2xx.exe
imdisplay.exe
magick.exe

I haven't renamed anything yet since I haven't seen a convert.exe but it did cross my mind to do that.

Yes. For "something.exe" use "magick". No need to rename anything.

For "-scale", you might prefer "-resize".

thanks for the super quick answers!

OK, You have IM 7, so

First try
That will show you the version of IM and the delegate libraries to be sure you can process PDF, JPG, PNG, TIFF etc. Show me what you have.

Then try
-resize is better than -scale. The latter will do block averaging and be more blurry.

For IM 7, in these documents, where it uses "convert", you should use "magick". If you need mogrify, montage, identify, etc, then use "magick.exe identify ...." etc. That is preface all the others with magick first.

Sorry, I am not a Windows user and so do not know much about Windows syntax.
