more strong convert function

[littledu]

I want to solve the rgba for old ie, the code maybe:

background-color:rgba(207,10,60,0.5);
filter:progid:DXImageTransform.Microsoft.gradient(enabled='true',startColorstr='#7FCF0A3C', endColorstr='#7FCF0A3C');

startColorstr=#7F... , 7F is from opacity(0.5). In less, no function convert. Can you supply more strong function in less?

Maybe the function called like:

LESS:

opacity-no-text(#cf0a3c,.5);

CSS

background-color:rgba(207,10,60,0.5);
filter:progid:DXImageTransform.Microsoft.gradient(enabled='true',startColorstr='#7FCF0A3C', endColorstr='#7FCF0A3C');

just a example. that is all.

i'm so sorry, my english is so poor, thanks!

You can do this already:

.test {
    @color: rgba(207,10,60,0.5);
    @msColor: argb(@color);
    background-color: @color;
    filter: ~"progid:DXImageTransform.Microsoft.gradient(enabled='true',startColorstr='@{msColor}', endColorstr='@{msColor}')";
}

--output:

.test {
  background-color: rgba(207, 10, 60, 0.5);
  filter: progid:DXImageTransform.Microsoft.gradient(enabled='true',startColorstr='#80cf0a3c', endColorstr='#80cf0a3c');
}

Just in case all those quotes are not really necessary there, the following syntax should work just fine:

.test {
    @c: argb(rgba(207, 10, 60, 0.5));
    filter: progid:DXImageTransform.Microsoft.gradient(
        enabled=true, startColorstr=@c, endColorstr=@c
    );
}

@ALL
Thanks for your answer. i know the argb function, but i think the alpha convert like

(0.5 * 255).toString(16) -> 7f

so, i was wrong.

@seven-phases-max Ah, I didn't realize escaping was no longer necessary for MS's filter:progid: format.
