Network Packet Troubleshooting Guide-class Linux platform background informationI've been testing k8s recently, and if you know or get in touch with Docker, you know that most of the networks associated with Docker are on bridging, routing, Iptables. If you happen to have contact with k8s, and understand the principle behind it, you must know that Kube-proxy iptables play to fly up. Of course, you may think of some of the wrong tools, such as I used to grab the package tool, or route tracking to

------------------------------------------------------------------------------------------- There are no string types in the C language, but there are many string-handling functions available for the convenience of manipulating strings. such as: input and output string, copy of string, connection, comparison and other operation functions. It is important to note that in the use of input and output, i.e. gets,The puts function should introduce the header file In addition, the use of connectedWhe

Copy CodeThe code is as follows: Original image $DST = "/upload/20120914/20120914040740-0.jpg"; Note that the picture path should be correct Get the original picture information $DST _info = getimagesize ($DST); Switch ($DST _info[2]) { Case 1: $DST _im =imagecreatefromgif (

Add watermark to the picture is a common and very useful function of PHP program, let me give you a detailed introduction to the PHP PNG transparent background Watermark program code bar. The code is as follows Copy Code Original image$DST = "/upload/20120914/20120914040740-0.jpg"; Note that the picture path should be correctGet the original picture information$DST _info = getimage

The prototype of the known strcpy function is:Char *strcpy (char *dst, const char *SRC); Implementing the strcpy function Explain why you want to return char * If you consider the case of DST and src memory overlap, strcpy how to implement implementation code for 1.strcpyChar* STRCPY (Char*DST,Const Char*SRC)//[1]{assert (

Most of the site generated thumbnails are proportional operation, today we look at can be fixed picture size "> picture size, not enough place automatically fill in the blanks Oh."

Sometimes upload images need to add a watermark to the site, watermark can be divided into text watermark and image watermark, the following implementation of these two kinds of watermark text watermark is to add text on the picture, mainly using the Imagefttext method of GD library, and need font file. The effect figure is as follows: The implementation code is as follows: nbsp; code as follows: $dst _path = ' dst.jpg '; nbsp;//Create an instance

Copy Code code as follows: Original image $DST = "/upload/20120914/20120914040740-0.jpg"; Note that the picture path should be correct Get the original picture information $DST _info = getimagesize ($DST); Switch ($DST _info[2]) { Case 1: $DST _im =imagecreatefro

Text watermark Text watermark is to add text on the picture, mainly using the Imagefttext method of GD library, and need font file. The effect chart is as follows: The implementation code is as follows: Copy Code code as follows: $dst _path = ' dst.jpg '; Create an instance of a picture$DST = imagecreatefromstring (file_get_contents ($DST _path

Copy Code code as follows: function My_image_resize ($src _file, $dst _file, $dst _width=32, $dst _height=32) { if ($dst _width echo "Params width or height error!"; Exit (); } if (!file_exists ($src _file)) { Echo $src _file.

Most of the site generated thumbnails are proportional operation, today we have to see the size of the image can be fixed "> image size, not enough to automatically fill the blank Oh.

Text Watermark Text watermark is to add text on the picture, the main use of GD library Imagefttext method, and the need for font files. As follows: The implementation code is as follows: Copy the Code code as follows:$dst _path = ' dst.jpg '; Create an instance of a picture$DST = imagecreatefromstring (file_get_contents ($DST _path)); Make a text.$font = './SIM
