Support quality parameter via ImageTagHelper for webp format

[zeto]

It is possible to set the quality attribute for jpg:

e.g. <contentful-image jpg-quality="80">

However this doesn't seem possible with the webp format, even though it is supported underneath in the Images API. Can this parameter be exposed by webp-quality (or maybe unifiying both with a quality attribute) ?

Thank you!

@zeto thanks for the suggestion. Yes, the attribute is poorly named. It is only a wrapper for the quality attribute so if even if you have a webp image I think it should still work if you set the jpg-quality attribute, but I will make sure to rename it (or expose a new one) in the next release.

if (JpgQuality.HasValue && isJpg)
{
    queryBuilder.SetJpgQuality(JpgQuality.Value);
}

It gets discarded at the moment (thats how I found out) due to not being JPG which makes sense due to the name of the parameter, but maybe it should ignore the format, the images API documentation mentions non 8-bit PNGs. (AVIF maybe also applies ?)

I will make sure to rename it (or expose a new one) in the next release.

Thank you!

@zeto ah yes, it's discarded, that's unfortunate. I'll let you know when this is fixed and available.

@zeto thanks for your patience. This should now be fixed in version 7.2.2
