Class GravatarIconSource

Namespace

Tharga.Team

Assembly

Tharga.Team.dll

Built-in IIconSource that resolves a user subject with an email to its Gravatar image, when enabled via IconSettings. Registered after StoredIconSource and any consumer sources, so an explicitly uploaded user icon (and custom sources) take precedence and Gravatar is a fallback. Returns null for team subjects, users without an email, or when disabled.

Parameters

settings IconSettings

Methods

AvatarUrl(string, string)

The Gravatar URL for email at style.

public static string AvatarUrl(string email, string style)

Parameters

email string

The user's email.

style string

One of All; null or blank means Default.

Returns

string

An absolute URL, or null when email is missing.

PreviewUrl(string, string)

The URL that previews what style looks like, rather than what email looks like.

public static string PreviewUrl(string email, string style)

Parameters

email string

The email to preview against, usually the signed-in user's.

style string

One of All.

Returns

string

An absolute URL, or null when email is missing.

Remarks

f=y is what makes this a preview of the style. Gravatar serves the account's own photo whenever the email has one, whatever d asks for — so without forcing the default, every style previews identically for anybody who has a Gravatar, and a style picker reads as broken.

ResolveAsync(IconSubject, CancellationToken)

Resolve an image for subject, or null to defer to the next source.

public Task<IconImage> ResolveAsync(IconSubject subject, CancellationToken cancellationToken = default)

Parameters

subject IconSubject

cancellationToken CancellationToken

Returns

Task<IconImage>
