No matter what, second parameter of convert always invalid.

[blindley]

I'm trying out some things from the examples on the main site, like this:

Code: Select all

convert -background lightblue -fill blue -font Candice -pointsize 72 label:Anthony label.gif

I get the error:

Code: Select all

Invalid Parameter - lightblue

In fact, no matter what I enter, as long as there are 2 or more parameters, it always just tells me the second parameter is invalid. I'm doing this in Windows Powershell.

Can you get anything to work? The problem may be that windows is using its convert program and not Imagemagicks.

Yes, that was it. Thanks. I moved ImageMagick to the front of my path now.

Thats interesting as most people seem to rename the Imagemagicks convert program - I have never had this problem on any of my installs - so making Imagemagick the first item on the enviromental path fixes it?

Well, I would do that, but seeing as how I've never ever used or even heard of this Windows convert program, and I have no idea what it does and doubt I'll ever use it, I'm not worried about the name collision. Besides, when I add things to my path, it's only on a per powershell-session basis. I have a script that allows me to simply type

Code: Select all

Add-Path("imagemagick","python3","whateverelse")

and voila. It used to add them to the end, now it adds them to the beginning.

so making Imagemagick the first item on the enviromental path fixes it?

Yep.

Hi. I am trying to run this command via R. I am using the following command: `system("convert -delay 80 *.png example_1.gif")` and i get the same error. Does anyone know how could i fix it ? (i do not know how to add imagemagick in the path also)

[snibgo]

I don't know R. Perhaps it has documentation that tells you how to change the path. Or perhaps it simply inherits the path from the operating system (Windows, Unix, whatever).

Sorry for the gravedigging, but as I installed ImageMagick-7.0.7-28-Q16-x64-static today, the "convert" command appears to show similar behaviour as outlined here.

Is there a simple (cmd ?) fix for this ?

[snibgo]

At your v7 installation, you probably didn't tick the box for "legacy" components, so it didn't install convert.exe, so that command runs the Microsoft program.

I suggest you use "magick" instead of "convert".

[Rye]

Ok. However, which of these "is" the "legacy checkbox" ?



The problem isn't "convert.exe"... I rely on "mogrify" for many scripts (for which I don't want to change it)...

IM 7 uses magick. When you use convert, it is actually running the legacy IM 6. So if you really want the new features of IM 7, then use magick, not convert.

[Rye]

Ah ok, that makes sense.

[snibgo]

From ImageMagick-7.0.7-28-Q16-HDRI-x64-dll.exe, I get this:

I don't know why you don't have that option.

For "mogrify", "identify" etc use "magick mogrify", "magick identify" etc.

[Rye]

I know why.
The static built is missing that option.
The others have it.

This is good to know since IM's behavior on this seems a bit misleading. That is, on my High Sierra system, I get the following identical output when getting the version of both commands:

Code: Select all

I have only v. 7 installed (via homebrew).

Yet it does look like `convert` is not the same as `magick`, though it is the same as `magick convert`, based on its inability to use the new fx function, as in

Code: Select all

magick rose: -resize %[fx:w*5]x show:

That is, replacing or supplementing `magick` with `convert` results in an error, whereas `magick` all by itself works as expected.

Is there an easier way to tell/show that convert is actually using version 6?
