Ok, got it!

exec('/usr/bin/convert "logogrey.bmp" -colorspace HSL -channel G -separate -format %[fx:mean] info:',$return_info );
echo $return_info[0];

It was the [0] bit as it;s an array being returned.

Thank you. To get a clearer idea I am using

exec('/usr/bin/convert "logo1.bmp" -colorspace HSL -channel G -separate -thumbnail 200x200 -format %[fx:mean] info: ');
I cannot get the 'info' bit returned. I have already looked through the area you mentioned but could not find anything?

Sorry but I'm new to all of this!

Using Powershell I can find if PDF pages have colour using:

$colour = convert "$PDF" -colorspace HSL -channel G -separate -format %[fx:mean] info:
echo $colour

0 = B/W
>0 = colour

All is well.

I want to do this on my hosted website using PHP but don't know how ...

Thanks. I'm not the greatest coder but I put a \n, converted it to a string, searched for the first space and split the string and converted back to an integer - sure someone can do it easier but it does now work!!!

$page_count_raw=$(identify -ping -format %n\n c:\mark\temp\count\Test.pdf)

Dear Gurus,

I'm trying to use the command I've read a few times but cannot get it to work properly. I wish to count the pages in a PDF. I have tried:

identify -format %n image.pdf

However, if it is 2 pages I get 22
If it is 6 I get 666666
If it is 55 I get 555555555555555555555555555555 ...
