Imagemagick Help

[emma57573]

I have a line of code that has been working for over a year, then two days ago it failed in a few areas on my site and I hadnt made any changes. I contacted the host and there was no server updates etc.

 

Its a php/imagemagick issue, basically the "widthxheight^    - Minimum values of width and height given, aspect ratio preserved" command does not work and fails to import the image at all when I add ^ to my code.

 

I need it though and im getting fustrated, for now ive changed my code to:

			exec("convert $path1 -thumbnail 200x180 -colorspace rgb -gravity center -extent 170x150 $path2");

 

which works ok but is not spot on like it was before, what I really want is

 

			exec("convert $path1 -thumbnail 170x150^ -colorspace rgb -gravity center -extent 170x150 $path2");

 

 

What ever I do I cant get ^ to work anymore but oddly all other imagemagick commands are fine.
