[zxsz4084]

I found function "getImageProperties" can get exif info like this：

Code: Select all

 $im->getImageProperties("exif:*");

getImageProperties:

convert in.jpg -format %[EXIF:*] info:

Dear snibgo：
I am very glad to see you again。

Today I get a question from an ios developer ，he says an img created by iPhone camera size 2448 x 3264 ，but upload to server it return json shows size 3264 x 2448 ，the width and the height is upside down。
I find php function “getimagesize” result is just 3264 x 2448 。I have found some info about exif。It may related to the exif:Orientation 。

http://www.impulseadventure.com/photo/e ... ation.html

when exif:Orientation equal 6 or 8 ， should exchange the width with the height each other ？

"-auto-orient" should solve this. See http://www.imagemagick.org/script/comma ... uto-orient and http://im.snibgo.com/orient.htm
