[SOLVED] ImageMagick path on Windows

We are at beta3 now. See if using a experimental version works:
FAQ: How do I upgrade?

Windows is not a supported platform for G3.

Just the opposite. The quirks and bloat is staying out by focusing on a single platform. EVERY TIME you make something cross platform your code base is larger than if you focused on a smaller set.

Yes. If a dedicated Windows, PHP developer wanted to come on board, they'd be welcome with open arms. They'd have to be able to dedicate 100s of hours per year to coding and support, but they'd be very welcome. Windows is not what we know for support and know what the devs know for programming so we've given more focus to the project unlike G2 which was the "every thing under the sun" application. Which made if very hard to code for and learn and why it took so long to get even a fraction of the traction we have for themes and modules happening in G3 already.

Linux
Apache 2.2
PHP 5.2.3 or newer
MySQL 5.x or newer

G2 isn't going away. G3 is not going to satisfy all of the G2 users.

I've ran G3 on Windows using XAMPP (Apache, MySQL, PHP) without major issue. But I never installed IM and configured that.

Take a look at /modules/gallery/helpers/graphics.php

There you'll see that it's using a Linux specific command to find the binaries, which is probably failing on Windows. You'll need to at least modify the line that contains exec("which convert") to make that work on Windows.

Thanks for the feedback guys. I can understand what you are saying regarding platform independence. I always had the thought that using PHP functions would free you of any ties to the underlying operating system or web server, obviously not though. I can definately offer assistance on the Windows/IIS side of things, but I struggle to spell PHP let alone code it.

Anyway, I was able to get around the issue I reported by going to admin -> settings -> advanced and manually setting the values for graphics_toolkit_path and graphics_toolkit. Works a treat. Just need to figure out why my G2 import stalls at picture 1906 of 3880 each time.

Cheers

Windows uses the where command to locate the information. I would also be recommended if you use the output variable in the exec call rather than assigning it to $path. Mainly because at least in windows you can get multiple lines returned. I changed line line 388 of graphics.php to the following:
exec("where convert", $paths);
$path = $paths[0];

it was

$path = exec("which convert");

It works on my Windows 7 install only because ImageMagick is the first in my PATH variable. there is a convert.exe in the Windows/System32 directory which will also come up when using the where command in Windows.

A true solution to the problem would be to use the PHP_OS in an if statement

if(stristr(PHP_OS, 'win')){
exec("where convert", $paths);
$path = $paths[0];
} else {
$path = exec("which convert");
}

In the GraphicsMagick section it would be similar
if(stristr(PHP_OS, 'win')){
exec("where gm", $paths);
$path = $paths[0];
} else {
$path = exec("which gm");
}

This still isn't perfect since it assumes that the first location found is the ImageMagick directory and the correct one. I found ImageMagick does not uninstall previous versions so this could be a problem as well if the ImageMagick directory is not first int he path.

Psychoph, seems like you have a solution many of us windows users are looking for. How to get ImageMagick working with G3. I don't know if it's me , but for some reason I can't find files graphics.php and movie.php anywhere on my PC. I have G3 installed, I looked through all the folders, made an extensive search and nothing. I'd like to modify the lines you suggested to make it work, but I don't have those files.
Would you advise please?
Tom.

I can sort of understand that, except the team is forcing OS specific support only for an os with the use of which. Alternatives I can think of would be:
1. Create an administrator configurable variable that point to the commands to be used, defaulting to linux commands, rather than hard coding.
2. Windows system administrators create an alias to where with the name which so that the linux which command is found probably a .bat that just calls where i will have to research that
3. Use the graphics toolkit directory variable to find the files if they are not found by which.

I guess as far as I can think there are a lot of options to code to OS differences through variables that don't sacrifice speed in the process. At the moment I don't know how to create server variables in gallery 3 but there is already a set of 20-30 in the advance settings seems simple enough to add which command, or use the graphics tool kit directory.

I personally will probably just stick with replacing which with where in my code and deal with collisions with git if the core team changes the code.
