How to use -magnify?

[holden]

This bit of code gives me an error:

Code: Select all

convert image.png -magnify imagebig.png

I get this:

convert: unrecognized option `-magnify' @ error/convert.c/ConvertImageCommand/2030.

From what I can tell no value is needed after the -magnify command, based on the limited info availble here and in the manual. I only want to do a 2x scale. Thanks!

It works fine for me, IM v6.9.0-0. Perhaps your version is too old.

How old is your version of IM? It may need a more current version of IM. Please, when posting a questions, always identify you version of IM and platform.

trying to use the same command by OP on IM version 7.0.06-0 and still get the same error. Is it discontinued in this version or an alternative exists? Please help!

Works fine for me on IM 6.9.8.10 Q16 non-HDRI Mac OSX and IM 7.0.6.1 Q16 HDRI Mac OSX. The -magnify option was created in more recent versions of ImageMagick, although I cannot find a record where that started in the changelog. So it won't work on very old versions of IM 6.

It works fine in IM 7, but note you need to use "magick" rather than "convert"
