Use C to implement PHP extended Image_Tool image processing tools

This extension is implemented based on ImageMagick. image operations call ImageMagickAPI 1. class documentation.

Class Image_Tool {/*** construct Image_Tool object * @ param string | array $ img_data * $ img_data can be the image path */function _ construct ($ img_data = ""); /*** add text annotations, or the text used for text watermark * @ access public * @ param string $ txt UTF8 encoding * @ param float $ opacity sets the transparency * @ param constant $ gravity * to set the text placement location: * the following attributes can be set for the NorthWest, North, NorthEast, West, Center, East, SouthWest, South, SouthEast, Static * @ param array $ font array: * name, constant, font name. Add Chinese annotations. use a Chinese font. otherwise, garbled characters are displayed. * Supported fonts: SimSun (, default), SimKai (SimHei), SimHei (), MicroHei (Micron black), Arial * weight, font width, int * size, font size, int * color, font color, for example: "blue", "# 0000ff", "rgb (255,)", etc., the default is "black "; * @ return boolean */function annotate ($ txt, $ opacity, $ gravity, array $ font);/*** Re-initialize the object data, it is used to repeatedly reuse an Image_Tool object * @ access public * @ return void */function clean (); ** image synthesis, which can be used to synthesize multiple images, you can also use * @ access public * @ param int $ src_im as an image watermark.
