Use C to implement PHP extended Image_Tool image processing tools

I. Class Document Description

Copy codeThe Code is as follows: class Image_Tool {
/**
* Construct the Image_Tool object
* @ Param string | array $ img_data
* $ Img_data can be the image path
*/
Function _ construct ($ img_data = "");

/**
* Add text annotations or use them as text watermarks
* @ Access public
* @ Param string $ txt UTF8 encoded text
* @ Param float $ opacity sets transparency
* @ Param constant $ gravity
* Set the text placement position:
* NorthWest, North, NorthEast, West, Center, East, SouthWest, South, SouthEast, Static
* @ Param array $ font the following attributes can be set for the font array:
* Name, constant, and font name. If you need to add a Chinese annotation, use a Chinese font. Otherwise, garbled characters are displayed.
* Supported fonts: SimSun (, default), SimKai (SimHei), SimHei (), MicroHei (micron black), and Arial
* Weight, font width, int
* Size, font size, int
* Color: Specifies the font color, for example, "blue", "# 0000ff", and "rgb (255,)". The default value is "black ";
* @ Return boolean
*/
Function annotate ($ txt, $ opacity, $ gravity, array $ font );

/**
* Reinitialize the data of an object to reuse one Image_Tool object multiple times.
* @ Access public
* @ Return void
*/
Function clean ();

*
* Image merging: You can merge multiple images or use them as image watermarks.
* @ Access public
* @ Param int $ src_img: The target image, which can be an ImageTool object or binary image data.
* @ Param int $ x the X coordinate of the merged canvas
* @ Param string $ y the Y coordinate of the merged canvas
* @ Return boolean
*
Function composite ($ src_img, $ x, $ y );

/**
* Error message returned
* @ Access public
* @ Return string
*/
Function errmsg ();

/**
* Error code returned
* @ Access public
* @ Return int
*/
Function errcode ();

/**
* Image Processing
* @ Access public
* @ Param string $ format
* @ Param boolean $ display
* @ Return boolean | if $ display is set to true, void is returned. Otherwise, binary data is returned. False is returned when a failure occurs.
*/
Function exec ($ format, $ display = false );

/**
* Horizontal flip
* @ Access public
* @ Return boolean
*/
Function flipH ();

/**
* Vertical flip
* @ Access public
* @ Return boolean
*/
Function flipV ();

/**
* Retrieving image attributes
* @ Access public
* @ Return array | boolean returns false if an error occurs.
*/
Function getImageAttr ();

/**
* Noise Removal to improve image quality, usually before exec
* @ Access public
* @ Return boolean
*/
Function improve ();

/**
* Proportional scaling is performed when only width or height is specified.
* @ Access public
* @ Param int $ width
* @ Param int $ height
* @ Param boolean $ thumbnail whether to clear additional Image Information
* @ Return boolean
*/
Function resize ($ width, $ height, $ thumbnail = true );

/**
* Scale proportionally. 1 is the original size
* @ Access public
* @ Param float $ ratio
* @ Param boolean $ thumbnail whether to clear additional Image Information
* @ Return boolean
*/
Function resizeRatio ($ ratio, $ thumbnail = true );

/**
* Rotate the image clockwise.
* @ Access public
* @ Param int $ degree rotation degree (0-360)
* @ Return boolean
*/
Function rotate ($ degree = 90 );

/**
* Set the binary data of the image to be processed
* @ Access public
* @ Param string $ img_blob
* @ Return boolean
*/
Function setData ($ img_blob );
}
