convert: Unrecognized option (-strip)

[lucg]

Hi,

My web hosting provider currently offered ImageMagick 5.4.7. When I run the following code

Code: Select all

system("exec 2>&1; convert temp/$file    -resize 400x500\> -quality 70 -density 72x72 -strip $newname");

I get an error message : convert: Unrecognized option (-strip). Is it because the strip option was implemented after version 5.4.7? If that's the case, is there a work around I could use to get the same result as strip?

Thanks.

Try -thumbnail instead of -resize as that automaticaly strips the EXIF data etc.

-thumbnail is not a recognized option.

Is there a file format that would not retain the info that -strip gets rid of? This way, I could convert my files to this file format first and then convert them back to jpeg.

Thanks.

I am on a lot later version than you but your resize gives me a problem; what if you use this instead ?

Code: Select all

system("exec 2>&1; convert temp/$file -resize \"400x500>\" -quality 70 -density 72x72 -strip $newname");

Also if you run this it should give the information of what is and isn't supported in your IM setup.

Code: Select all

<?php
// Build the array of items to be used
exec("convert convert -list list", $IMarray, $code);
// Start the loop to find and display the results
foreach ($IMarray as $value) {
echo "<br>system (\"convert -list $value\")";
echo "<pre>";
system("convert -list $value");
echo "</pre><hr>";
}
?>

The equivalent option to -strip in IM version 5 was +profile '*'.

You version of IM however is more than 7 years old!!!!!
