MoinMoin - ImageLink Macro
5
This macro is used to make a link that displays an image (can be given
6
as either attachment or URL) and links to either an URL or a wiki page.
7
Optionally the size of the image can be adjusted.
8
If no target is given the link will point to the image itself.
11
[[ImageLink(image, [target,] [width=width, [height=height]])]]
14
image: image attachment file name or the URL of an image
15
target: link target wiki page or URL (optional)
18
width: rendered image width (optional)
19
height: rendered image heigth (optional)
20
alt: text for img tag "alt" attribute
23
[[ImageLink(M�nchen.png,M�nchen,height=100)]]
24
[[ImageLink(Images/M�nchen.png,M�nchen,height=100)]]
25
[[ImageLink(http://webcam.portalmuc.de/images/webcam/webcam_marienplatz.jpg,M�nchen Marienplatz)]]
26
[[ImageLink(plot.png,width=200)]]
27
[[ImageLink(plot.png,height=200)]]
28
[[ImageLink(plot.png)]]
29
[[ImageLink(http://webcam.portalmuc.de/images/webcam/webcam_marienplatz.jpg,http://www.muenchen.de,width=150)]]
30
[[ImageLink(m�nchen.png,http://www.muenchen.de,width=50)]]
31
[[ImageLink(http://webcam.portalmuc.de/images/webcam/webcam_marienplatz.jpg)]]
32
[[ImageLink(example.png,alt=whateveryouwant(���))]]
36
wrote the first published version of this macro in 2001.
39
2004 intitial new version for MoinMoin 1.2
42
Implemented wikiutil.link_tag and macro.formatter.pagelink.
43
Added title attribute to the created link. One could generalize that to
44
add arbitrary attributes.
46
One could also add class attributes to <a> and/or <img> elements.
47
I do not see the need for such modifications. If however this is
48
to be done in the future one would need to add 'html_class' key to the kw dictionary
49
with a corresponding value to add class to <img> element. To add class to <a> element
50
one needs to add 'css_class' key with a corresponding value to the dictionary passed to
54
2004-12-23 Adapted to MoinMoin Version 1.3.1-1
55
2004-12-23 Syntax change Version 1.3.1-2
56
width and height and probably other keywords must be given as keywords (e.g. height=20)
57
2004-12-31 Version 1.3.1-3 code clean up
58
2005-01-16 Bug fixed in the errorhandler - found and patched by Malte Helmert
59
2005-03-05 Version 1.3.3-5 Bug fixed found by cypress ("If I put [[ImageLink(moinmoin.png)]] it bombs")
60
2005-03-28 Version 1.3.3-6 feature request added by CDPark:
61
"Can we use an external image? And an external target?"
62
2005-04-16 Version 1.3.3-7 no default alt tag definition as requested by CDPark and AlexanderSchremmer
65
2005-04-17 Version 1.3.3-8 code refactored
66
IMG with no alt tag is not recommended in the HTML standard.
67
It keeps a user specified alt tag. If there is none, it tries to make on using the WikiName
68
or image name instead.
71
2005-04-21 Version 1.3.3-9 bug fixed
72
When the image does not exist yet, it gives you a "Upload Image" link, this link does not
73
work. I suspect that this only is a problem on sub-pages, caused by incorrect escaping of
76
2005-12-19 Versiom 1.5.0-10 feature added to link to images on different wiki pages
77
2006-02-14 Version 1.5.2-11 bug fixed for filename of attached image is Chinese (encode added)
78
2006-02-22 Version 1.5.2-12 code refactored

The method used here is pretty dumb. Improvements are welcome.
