Generate webpage snapshots in image format based on linnux + phantomjs

In the code area, I saw a code for generating site snapshots. After reading the code for half a day, I found that the author only posted the Business Code. Instead, the code for generating snapshot images at the core was not provided. Remember to scale down websites provided by google Search

Installation extension:
(1) The following is the installation process on linux. If git is not installed, run yum install git first.
Install casperjs

The Code is as follows:

Cd/
Git clone git: // github.com/n1k0/casperjs.git
Cd casperjs
Ln-sf/casperjs/bin/casperjs/usr/local/bin/casperjs // you can ignore the actual execution in which php is executed/casperjs/bin/casperjs

(2) install phantomjs ,:
After the download, the operation is very simple. simply move the decompressed \ bin \ phantomjs to \ usr \ local \ bin \ phantomjs. \
Test phantomjs -- if there is a result of version, no error is reported. The installation is OK.

(3) install fonts
1. first obtain a set of "" library (Google click), which contains two files: msyh. ttf (common) and msyhbd. ttf (BOLD );
2. Create a sub-directory under the/usr/share/fonts directory, for example, win. The command is as follows:

The Code is as follows:

# Mkdir/usr/share/fonts/win

3. Copy msyh. ttf and msyhbd. ttf to this directory. For example, if the two files are stored in/root/Desktop, run the following command:

The Code is as follows:

# Cd/root/Desktop
# Cp msyh. ttf msyhbd. ttf/usr/share/fonts/win/

4. Create a font index to update the font cache:

The Code is as follows:

# Cd/usr/share/fonts/win
# Mkfontscale (if mkfontscale: command not found is prompted, you must install it yourself # yum install mkfontscale)
# Mkfontdir
# Fc-cache (if fc-cache: command not found is prompted, install # yum install fontconfig)

Now, the font has been installed!
