《PHP實戰：MacOS 安裝 PHP的圖片裁剪擴展Tclip》要點：
本文介紹了PHP實戰：MacOS 安裝 PHP的圖片裁剪擴展Tclip，希望對您有用。如果有疑問，可以聯系我們。
Tclip 用于圖片裁剪,有以下特點：PHP實戰
能進行人臉識別.圖片中有人臉,將自動視為人臉區域為重要區域,將不會被裁剪掉.
自動識別其它重要區域.如果圖片中未識別出人臉,則會根據特征分布計算出重區域.
總而言之,自動識別圖片中的重要區域,并且在圖片裁剪時保存重要區域.

安裝opencvPHP實戰
根據github上的闡明,在CentOS上安裝沒有問題,但在我的MacOS上就掛了.PHP實戰
首先遇到的問題便是,opencv安裝不過去.還好,上github下載最新的opencv-2.4.11 安裝成功.PHP實戰
下載地址：https://github.com/Itseez/opencv/releasesPHP實戰
使用當前最新版本 OpenCV 2.4.11PHP實戰
安裝依賴PHP實戰
在安裝opencv之前,先安裝一些依賴包：PHP實戰
代碼如下:
brew install gtk+? pkgconfig libpng zlib libjpeg libtiff cmake
提示： brew的安裝使用請參考 http://brew.sh/PHP實戰
安裝opencvPHP實戰
開始安裝 opencv：PHP實戰
代碼如下:
tar zxf opencv-2.4.11.tar.gz
cd opencv-2.4.11
cmake CMakeLists.txt
make && make install
安裝php tclipPHP實戰
先下載：https://github.com/exinnet/tclip/archive/master.zipPHP實戰
然后繼續：PHP實戰
代碼如下:
unzip tclip-master.zip
cd tclip-master/php_ext
phpize
./configure
如果不出不測,到這一步,應該就掛掉了,提示：PHP實戰
代碼如下:
checking for opencv.pc file in default path... found in /usr/lib/pkgconfig
found in /usr/local/lib/pkgconfig
configure: error: no result from pkg-config opencv --libs --cflags opencv
在 Tclip 作者的頁面上 http://www.bo56.com/tclip%E4%BA%BA%E8%84%B8%E8%AF%86%E5%88%AB%E5%9B%BE%E7%89%87%E8%A3%81%E5%89%AA/#downloadPHP實戰
評論中,也有網友遇到了類似的問題,提出修改方法為：PHP實戰
將 config.m4 中的 判斷語句test ${i:${#i}-3} = “.so”,改為 test ${i:${#i}-6} = ".dylib”,并嘗試將46行的.so 也改稱 .dylib
依然提示no result的差錯～PHP實戰
再翻翻config.m4的代碼和執行 pkg-config opencv --libs --cflags opencv的輸出成果：PHP實戰
代碼如下:
-I/usr/local/include/opencv -I/usr/local/include -L/usr/local/lib -lopencv_calib3d -lopencv_contrib -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_gpu -lopencv_highgui -lopencv_imgproc -lopencv_legacy -lopencv_ml -lopencv_nonfree -lopencv_objdetect -lopencv_ocl -lopencv_photo -lopencv_stitching -lopencv_superres -lopencv_ts -lopencv_video -lopencv_videostab
感覺怎么對不上,于是跑到Linux安裝勝利的服務器執行了一下,輸出結果如下：PHP實戰
代碼如下:
-I/usr/local/include/opencv -I/usr/local/include /usr/local/lib/libopencv_calib3d.so /usr/local/lib/libopencv_contrib.so /usr/local/lib/libopencv_core.so /usr/local/lib/libopencv_features2d.so /usr/local/lib/libopencv_flann.so /usr/local/lib/libopencv_gpu.so /usr/local/lib/libopencv_highgui.so /usr/local/lib/libopencv_imgproc.so /usr/local/lib/libopencv_legacy.so /usr/local/lib/libopencv_ml.so /usr/local/lib/libopencv_nonfree.so /usr/local/lib/libopencv_objdetect.so /usr/local/lib/libopencv_photo.so /usr/local/lib/libopencv_stitching.so /usr/local/lib/libopencv_ts.so /usr/local/lib/libopencv_video.so /usr/local/lib/libopencv_videostab.so
再看他的斷定代碼：PHP實戰
代碼如下:
OPENCV_FLAGS="`pkg-config opencv --libs --cflags opencv`"
for i in $OPENCV_FLAGS;do
if test ${i:0:2} = "-I" ;then
PHP_ADD_INCLUDE(${i:2})
elif test ${i:${#i}-3} = ".so" ;then
dir_name=`dirname $i`
file_name=${i/$dir_name/}
file_name=${file_name/\/lib/}
file_name=${file_name/.so/}
PHP_ADD_LIBRARY_WITH_PATH($file_name,$dir_name,TCLIP_SHARED_LIBADD)
else
AC_MSG_ERROR([no result from pkg-config opencv --libs --cflags opencv])
fi
done
我立刻就明白了,Linux上輸出的都是具體的.so路徑,MacOS上都是相對的路徑,而config.m4中是根據具體路徑和擴展名判斷的,明白了問題,辦理就簡單了.PHP實戰
將 pkg-config opencv --libs --cflags opencv 的執行成果修改為具體的路徑,并替換到config.m4中：PHP實戰
代碼如下:
OPENCV_FLAGS="-I/usr/local/include/opencv -I/usr/local/include /usr/local/lib/libopencv_calib3d.dylib /usr/local/lib/libopencv_contrib.dylib /usr/local/lib/libopencv_core.dylib /usr/local/lib/libopencv_features2d.dylib /usr/local/lib/libopencv_flann.dylib /usr/local/lib/libopencv_gpu.dylib /usr/local/lib/libopencv_highgui.dylib /usr/local/lib/libopencv_imgproc.dylib /usr/local/lib/libopencv_legacy.dylib /usr/local/lib/libopencv_ml.dylib /usr/local/lib/libopencv_nonfree.dylib /usr/local/lib/libopencv_objdetect.dylib /usr/local/lib/libopencv_photo.dylib /usr/local/lib/libopencv_stitching.dylib /usr/local/lib/libopencv_ts.dylib /usr/local/lib/libopencv_video.dylib /usr/local/lib/libopencv_videostab.dylib"
再繼續執行：PHP實戰
代碼如下:
phpize
./configure
make
make install
順利安裝完成.PHP實戰
