Add size keywords in Image class

[v923z]

As discussed on the mailing list, it seems that it would be useful to add size-specific keywords to the image class, something like

Image('foo.png', width=100, height=20)

Don't forget the SVG class too if that makes sense. Might even be nice if we are downsizing the display of a large image to make it linked to show the full size image.

I just thought about the same lacking feature... but then thought that it might be worth just adding generic backend_opts keywords options, e.g.

 Image('foo.png', html_opts=", width=100, height=20")

which would result in a patch:

-            return u'<img src="%s" />' % self.url
+            return u'<img src="%s" %s/>' % (self.url, self.html_opts)

to handle it -- not sure though what would happen for embed=True

but may be such way it would be more scalable to accommodate ad-hoc demands ;-)

This was closed by #2231

What was the actual decision? It seems there is not any of these options implemented?

[minrk]

This was implemented as described in 1.0 by #2231. The Image constructor accepts width and height kwargs, which affect the display size of the image.

Here is what I am getting, it is fine for image filename alone but with other args it gives error as:

Are you on master ?

This is the version I am using. I am not sure I understood your question though.

You are not in master... the current stable version is 1.1.0, and we call master the development version 2.0.0.
I suggest you to use the current stable version...

[Carreau]

Yes, the keyword have been added recently, you should be ale o upgrade using EPD, I would also suggest migrating to Canopy that replace EPD now.

[moghimis]

I am sorry. I have just updated my Canopy. Works fine. Thanks for your time.
Thanks for all of your efforts.
