Enhancement: Allow for PNG stretch sizingMethod #17

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
At present IE7.js only uses the AlphaImageLoader crop sizingMethod (for CSS
background images), however there are situations where you would want to
use stretch. For example when the background is just a repeated semi
transparent pixel.

You *could* make the assumption that any background that isn't set to
no-repeat should use stretch rather than crop. Or alternatively, allow for
an extra flag in the file name, something like -stretch-trans.png, that
will trigger stretch rather than crop.

What do you think?

Mmm. It sounds like a good idea. Let me post it on the discussion group to see 
what
others think.

This sounds like an excellent idea. I've made workarounds for this before by
stretching bg images on server side. A solution within IE7 would be wonderful.
Perhaps, though, it's best to also implement a similar file name ending 
criteria as
Jack proposes.

My approval,

Changing this to "enhancement". I will try to add this functionality in a 
future release.

One thought:
If background-attachment:repeat-x is specified, could the bg be stretched
horizontally only, retaining the height?

@svarven,
No unfortunately you can't do that, AlphaImageLoader is fairly limited, it's 
stretch
across the entire element or don't stretch at all I'm afraid.

Sorry, I just realised I made a mistake. I meant "scale", not "stretch".

Unawared, I opened a new thread regarding the same suggestion.

How difficult is it to implement this idea?

it will be great for ie8.js

OK. This is how it will work in the next release. If you want the image to crop 
(how it 
currently works) then use no-repeat:

e.g. background-image: url(my-trans.png) no-repeat;

If you want the image to stretch (to imitate tiling) then omit the no-repeat 
flag.

This will apply in version 2.1.
