cutycapt

老大临时安排任务，要定期对大量（万为单位）的网站截图并归档保存。最早使用的是window下的一个解决方案：webshotcmd.exe+批处理。 运行了一段时间，发现经常弹出webshotcmd.exe程序未响应的窗口，需要人工点击确定后才能继续截图，而且webshocmd未注册版本截出的 图是灰色的，不方便查看。 google了下，发现了linux的两个截图工具cutycapt和phantomjs，经过测试，cutycapt截图较慢，但比较稳定，phantomjs截图速度较快，但时有出现进程假死的情况。权衡利弊，决定使用cutycapt+shell脚本的方式截图： webshot.sh #/bin/bash #webhsot #by caishzh 2013 WEBSHOTDIR="/data/webshot" mkdir -p $WEBSHOTDIR while read LINE do DISPLAY=:0 cutycapt --url=http://$LINE --max-wait=90000 --out=$WEBSHOTDIR/$LINE.jpg >/dev/null 2>&1 done<domain.txt 脚本很简单，就不注释了，domain.txt是网址列表。 cutycapt的安装和使用参照这里 。 执行脚本，可以正常截图，图片质量也很高。但另一个问题出现了

I am having a problem getting CutyCapt to work with SSL URLs, I have the most recent version of CutyCapt ( CutyCapt.cpp 10 2013-07-14 21:57:37Z ), it works perfect with all non-SSL URLs, when I try to grab a URL with SSL using the following command: ./xvfb-run ./CutyCapt --min-width=1280 --min-height=720 --max-wait=6000 \ --url="https://apple.com" --out="testssl.jpg" I get the following error: QPainter::begin: Paint device returned engine == 0, type: 3 QPainter::setRenderHint: Painter must be active to set rendering hints QPainter::setBrush: Painter not active QPainter::pen: Painter not active

Duplicate What is the best way to create a web page thumbnail? I want to display a thumbnail image of an HTML page. How can I do this? You might want to see if CutyCapt or IECapt are a good fit for your needs. Provide more information like if you are using PHP, ASP.net or a windows Application. If you are using PHP for example you can profit of the variety of Open Source extensions that can do the work for you. See how to Generate a Thumbnail of Any Webpage using PHP . Also have a look at WebThumb . I found several web sites that offer a service that will do this for you using http://www

上一篇中（ linux多线程网页截图-shell ），使用shell多进程对大量的网站截图，大大减少了截图的时间。但慢慢的也发现了这种方式的弊端：每个进程分配的网站数量是相等的，有些进程截图较快，有些较慢，个别进程在其它进程已经截图完成后，还要运行10多个小时才能把分配的网站截图完。 如何把现有的“平均分配”截图方式改成“能者多劳”呢？ 刚好最近在学习python，而python可以很方便的支持多线程。找了些资料，使用threading+queue的方式实现了“能者多劳”的多线程截图方式： #coding:utf-8 import threading,urllib2 import datetime,time import Queue import os class Webshot(threading.Thread): def __init__(self,queue): threading.Thread.__init__(self) self.queue=queue def run(self): while True: #如果队列为空，则退出，否则从队列中取出一条网址数据，并截图 if self.queue.empty(): break host=self.queue.get().strip('\n') shotcmd="DISPLAY=:0 cutycapt --url=http:

I'm writing a specialized crawler and parser for internal use, and I require the ability to take a screenshot of a web page in order to check what colours are being used throughout. The program will take in around ten web addresses and will save them as a bitmap image. From there I plan to use LockBits in order to create a list of the five most used colours within the image. To my knowledge, it's the easiest way to get the colours used within a web page, but if there is an easier way to do it please chime in with your suggestions. Anyway, I was going to use ACA WebThumb ActiveX Control until I
