[LDView] Different behaviour between command line and call from php application

[Hans Willison]

Hi,

When I create a snapshot from the command line, like so:

Code:

C:\>LDView64.exe "temp_3001-4.ldr" -SaveSnapshot="3001-4.png"

then LDView uses all the settings and preferences which I defined previously via the GUI.

When I use the same command from within a php application like so:

PHP Code:

<?php 

system('LDView64.exe "temp_3001-4.ldr" -SaveSnapshot="3001-4.png"');

I set all of the LDView options on the command line for the Parts Tracker (to avoid exactly the issue you're running into). Everything is settable and the documentation is extensive. If you have a question, ask and I can help.

Almost certainly the process (I assume a web server) running PHP is running under a different user account, and therefore has a different registry. LDView's settings are (by design) user-specific.

That's the solution! I am currently not on my PC so I can't check it there, but on my laptop it works as desired without changing anything!

The reason is: on my laptop I start my webserver environment (xampp) manually via xampp_start.exe. So webserver and PHP run under the user account I'm logged in.

On my PC xampp is started as a service at startup and is running under whatever user account windows services are running (Local System?). I will check as soon as I regain access to my PC.

On the other hand the -FOV setting works on my laptop, but didn't on my PC. I will also recheck on my PC.

Thank you all for your help

Short summary:

1) I'm back on my PC and changed the user account for the apache service from 'system' to my own user account and ldview works as desired when called from within my PHP application.
2) I also rechecked the -FOV setting and it works as desired. I obviously made a mistake on my previous attempts.
3) Now having two working solutions for my problem I decided on a third variant : I let my PHP application write all ldview commands to a batch file which I execute manually from a command prompt (which turns out better for mass creation of part images).
