hi how would i use the imagemagick command line code that i got from the user section in php
If i read the manual correctly this should keep the sizing within the aspect ratio right? height of 125px with a max width of 190px
convert large.jpg -auto-orient -thumbnail 190x125 tn_small.jpg

-thumbnail 190x125 will scale to 190 (assuming your image width>height)
-thumbnail 190x125^ will scale to 125 (assuming your image width>height)
on windows you need ^^ (as ^ is an escape character)
see
http://www.imagemagick.org/script/comma ... php#resize (-thumbnail should follow the same scheme as -resize)

See Rubble Web for examples of using command line IM from PHP scripts.

Versions after 6. something need the image reading in first.
-thumbnail strips the image anyway so you do not need -strip
-auto-orient only works if the image has the option ?
So I would try:
Code: Select all
exec("convert watermarked.jpg -thumbnail 190x125 -quality 75 tn_small.jpg");
What do you mean when you say its not working?

i changed it to resize and move the quality after the main image and everything works now
Code: Select all
exec("convert watermarked.jpg -quality 75 -resize 190x125 tn_small.jpg");
