Outlook does not support rgba

[borgsoftwaresystems]

I'm currently using HTMLSanitizer which in turn uses AngleSharp. We are trying to sanitize code for use in emails but AngleSharp is converting the folllowing:

<p style="background-color:#bbbbbb">
or:
<p style="background-color: rgb(187, 187, 187)">

into:
<p style="background-color: rgba(187, 187, 187, 1)

The problem is that Outlook (for whatever reason) still does not support rgba.

Could you please tell me if there is a way for me to tell AngleSharp to stop converting to rgba? If not, would you consider (if possible) providing a mechanism to support this?

Best regards,
Steve

I think we can support it. But it would require some efforts.

My question is: Is this really an issue in AngleSharp or rather in AngleSharp.Css? Because AngleSharp itself does not know anything about CSSOM such as colors.

Hi,

Many thanks for getting back to me so quickly. Yes, sorry about that, I didn't realise there were separate repositories - it is in AngleSharp.Css.

Shall I create a new issue in that repo and close the one here?

Best regards,

Steve

Transferred!

The Color struct is private.

This seems to keep the color format fixed. Is there a way to detect the color format when parsing the style? So hex stays hex and the same for rgb/a after a ParseStyleSheet call.

I think right now there is no such way.
