- -------====Website Screenshots configuration - BETA====-------
73
-
74
- If you just want image thumbnails and don't want website screenshots, you can safely leave this as is.
75
-
76
- If you would like to get website screenshots set up, you will need root access to your own server.
77
-
78
- Enable ALLOW_ALL_EXTERNAL_SITES so you can fetch any external web page. This is more secure now that we're using a non-web folder for cache.
79
- Enable BLOCK_EXTERNAL_LEECHERS so that your site doesn't generate thumbnails for the whole Internet.
80
-
81
- Instructions to get website screenshots enabled on Ubuntu Linux:
82
-
83
- 1. Install Xvfb with the following command: sudo apt-get install subversion libqt4-webkit libqt4-dev g++ xvfb
84
- 2. Go to a directory where you can download some code
85
- 3. Check-out the latest version of CutyCapt with the following command: svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt
86
- 4. Compile CutyCapt by doing: cd cutycapt/CutyCapt
87
- 5. qmake
88
- 6. make
89
- 7. cp CutyCapt /usr/local/bin/
90
- 8. Test it by running: xvfb-run --server-args="-screen 0, 1024x768x24" CutyCapt --url="http://markmaunder.com/" --out=test.png
91
- 9. If you get a file called test.png with something in it, it probably worked. Now test the script by accessing it as follows:
92
- 10. http://yoursite.com/path/to/timthumb.php?src=http://markmaunder.com/&webshot=1
93
-
94
- Notes on performance:
95
- The first time a webshot loads, it will take a few seconds.
96
- From then on it uses the regular timthumb caching mechanism with the configurable options above
97
- and loading will be very fast.
98
-
99
- --ADVANCED USERS ONLY--
100
- If you'd like a slight speedup (about 25%) and you know Linux, you can run the following command which will keep Xvfb running in the background.
101
- nohup Xvfb :100 -ac -nolisten tcp -screen 0, 1024x768x24 > /dev/null 2>&1 &
102
- Then set WEBSHOT_XVFB_RUNNING = true below. This will save your server having to fire off a new Xvfb server and shut it down every time a new shot is generated.
103
- You will need to take responsibility for keeping Xvfb running in case it crashes. (It seems pretty stable)
104
- You will also need to take responsibility for server security if you're running Xvfb as root.
105
-

2
- An elem for determining if an elem is within a certain
3
- distance from the edge above or below the screen, and attaching
4
- a function to execute once the elem is in view.
5
-
6
- General Usage:
7
-
8
- * Place the library anywhere in your JavaScript code before you
9
- intend to call the function.
10
-
11
- * To initialize Sonar with a different default distance, modify
12
- the sonar = Sonar() line immediately following the Sonar
13
- library definition. Example:
14
-
15
- sonar=Sonar(100); // Initializes Sonar with a 100px default distance.
16
-
17
- Note:
18
-
19
- * The default distance is 0 pixels.
20
-
21
-
22
- sonar.detect() Usage
23
-
24
- * Use sonar.detect(elem, distance) to check if the
25
- elem is within screen boundaries.
26
-
27
- @elem - The elem you want to detect visibility.
28
- @distance - The distance from the screen edge that should
29
- count in the check. Uses default distance if not specified.
30
-
31
- * Note: sonar.detect() adds a property to
32
- ojbects called sonarElemTop. Test to ensure there
33
- aren't any conflicts with your code. If there
34
- are, rename sonarElemTop to something else in the code.
35
-
36
- * sonar.detect() returns:
37
- true if the elem is within the screen boundaries
38
- false if th elem is out of the screen boundaries
39
-
40
- Example:
41
-
42
- Here's how to check if an advertisment is visible on a
43
- page that has the id, "ad".
44
-
45
- if (sonar.detect(document.getElementById("ad")))
46
- {
47
- alert('The ad is visible on screen!');
48
- }
49
- else
50
- {
51
- alert ('The ad is not on screen!);
52
- }
53
-
54
- sonar.add() Usage
55
-
56
- * This method stores elems that are then polled
57
- on user scroll by the Sonar.detect() method.
58
-
59
- * Polling initializes once the sonar.add() method is passed
60
- an elem with the following properties:
61
-
62
- obj : A reference to the elem to observe until it is within
63
- the specified distance (px).
64
-
65
- id : An alternative to the obj parameter, an "id" can be used
66
- to grab the elem to observe.
67
-
68
- call: The function to call when the elem is within the
69
- specified distance (px). The @elem argument will
70
- include the elem that triggered the callback.
71
-
72
- px : The specified distance to include as being visible on
73
- screen. This property is optional (default is 0).
74
-
75
- Example:
76
-
77
- sonar.add(
78
- {
79
- obj: document.getElementById("0026-get-out-the-way"),
80
- call: function(elem) // elem will include the elem that triggered the function.
81
- {
82
- swfelem.embedSWF("../player.swf", "0026-get-out-the-way", "640", "500", "9.0.0",
83
- {}, {file: "0026-get-out-the-way.flv", fullscreen: true},
84
- {allowfullscreen: true, allowscriptaccess: "always"});
85
- },
86
- px: 400
87
- });
88
-
89
- You can also specify an id tag to be grabbed instead of the elem:
90
-
91
- sonar.add(
92
- {
93
- id: "0026-get-out-the-way",
94
- call: function(elem) // elem will include the elem that triggered the function.
95
- {
96
- swfelem.embedSWF("../player.swf", "0026-get-out-the-way", "640", "500", "9.0.0",
97
- {}, {file: "0026-get-out-the-way.flv", fullscreen: true},
98
- {allowfullscreen: true, allowscriptaccess: "always"});
99
- },
100
- px: 400
101
- });
102
-
103
- Notes:
104
-
105
- * Setting the body or html of your page to 100% will cause sonar to have
106
- an invalid height calculation in Firefox. It is recommended that you
107
- do not set this CSS property.
108
-
109
- Example:
110
-
111
- html, body {
112
- height:100%; // Do not do this.
113
- }
114
-
115
- * If you want to set the default distance to something other
116
- than 0, either update the property directly in the code or
117
- you can do this:
118
-
119
- sonar.blip.d = 100; // Where 100 = 100 pixels above and below the screen edge.
120
-
121
- * Sleep well at night knowing Sonar automatically cleans up the
122
- event listeners on the scroll event once all calls have executed.
123
-
124
- Code History:
125
-
126
- v3 :: 8/14/2009 - David Artz (david.artz@corp.aol.com)
127
- * Fixed a bug in the polling code where splicing caused our
128
- for loop to skip over the next iteration in the loop. This
129
- caused some images in the poll to be detected when they
130
- should have been.
131
- * Re-factored Sonar to use the "Module" JavaScript library
132
- pattern, making our private variables and functions more
133
- private and inaccessible from the public interface.
134
- * Updated the sonar.add() function to return true or false,
135
- useful for determining if Sonar added the elem to the
136
- poll or executed its callback immediately.
137
-
138
- v2 :: 3/24/2009 - David Artz (david.artz@corp.aol.com)
139
- * Added support for IE 8.
140
- * Updated the way scroll top and screen height are detected, now
141
- works in IE/FF/Safari quirks mode.
142
- * Added null check for IE, it was polling for an elem that had recently
143
- been spliced out of the array. Nasty.
144
- * Modified for loop to use standard syntax. for (i in x) is known to be
145
- buggy with JS frameworks that override arrays.
146
- * Added sonar.b property to cache the body element (improving lookup time).
147
-
148
- v1 :: 11/18/2008 - David Artz (david.artz@corp.aol.com)
149
- * Officially released code for general use.

  == Installation ==
31
  1. Download and unzip plugin
49
  = Whoa, this plugin is using JavaScript. What about visitors without JS? =
50
  No worries. They get the original element in a noscript element. No Lazy Loading for them, though.
51
 
 
 
 
52
  = I'm using a CDN. Will this plugin interfere? =
53
  Lazy loading works just fine. The images will still load from your CDN.
54
 
55
  As of version 0.6.0, serving responsive and hiDPI images will not work if you're using a CDN. Pull zones will be supported in the near future.

- -------====Website Screenshots configuration - BETA====-------
73
-
74
- If you just want image thumbnails and don't want website screenshots, you can safely leave this as is.
75
-
76
- If you would like to get website screenshots set up, you will need root access to your own server.
77
-
78
- Enable ALLOW_ALL_EXTERNAL_SITES so you can fetch any external web page. This is more secure now that we're using a non-web folder for cache.
79
- Enable BLOCK_EXTERNAL_LEECHERS so that your site doesn't generate thumbnails for the whole Internet.
80
-
81
- Instructions to get website screenshots enabled on Ubuntu Linux:
82
-
83
- 1. Install Xvfb with the following command: sudo apt-get install subversion libqt4-webkit libqt4-dev g++ xvfb
84
- 2. Go to a directory where you can download some code
85
- 3. Check-out the latest version of CutyCapt with the following command: svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt
86
- 4. Compile CutyCapt by doing: cd cutycapt/CutyCapt
87
- 5. qmake
88
- 6. make
89
- 7. cp CutyCapt /usr/local/bin/
90
- 8. Test it by running: xvfb-run --server-args="-screen 0, 1024x768x24" CutyCapt --url="http://markmaunder.com/" --out=test.png
91
- 9. If you get a file called test.png with something in it, it probably worked. Now test the script by accessing it as follows:
92
- 10. http://yoursite.com/path/to/timthumb.php?src=http://markmaunder.com/&webshot=1
93
-
94
- Notes on performance:
95
- The first time a webshot loads, it will take a few seconds.
96
- From then on it uses the regular timthumb caching mechanism with the configurable options above
97
- and loading will be very fast.
98
-
99
- --ADVANCED USERS ONLY--
100
- If you'd like a slight speedup (about 25%) and you know Linux, you can run the following command which will keep Xvfb running in the background.
101
- nohup Xvfb :100 -ac -nolisten tcp -screen 0, 1024x768x24 > /dev/null 2>&1 &
102
- Then set WEBSHOT_XVFB_RUNNING = true below. This will save your server having to fire off a new Xvfb server and shut it down every time a new shot is generated.
103
- You will need to take responsibility for keeping Xvfb running in case it crashes. (It seems pretty stable)
104
- You will also need to take responsibility for server security if you're running Xvfb as root.
105
