Hi i am creating a thumbnail using imagemagick by following command
convert -define jpeg:size=".$this->info[0]."x".$this->info[1]." testi/".$this->filename." -auto-orient -thumbnail 200x200 -unsharp 0x.5 testi/".$this->filename
but this command only runs for jpack input file.
Can anyone tell me the command for any file type? like if gif then output shuld gif ?
分享 What is a jpack file?
The -define will only work for jpg files but I thought if the output file was not a jpg it would be ignored; try removing that.
The output file should be the same name as the input file.
Try writing your code like this so you can see what the command actualy is; you can comment the echo out when its working.
$cmd = "-define jpeg:size={$this->info[0]}x{$this->info[1]} testi/{$this->filename} -auto-orient -thumbnail 200x200 -unsharp 0x.5 testi/{$this->filename}";
echo $cmd;
exec("convert $cmd");
I got a bit lost with the "$this->" business and so the code may not work as written. I try and keep things simple in my commands and would have put the filenames etc. into a variable outside the Imagemagick command.
