avatar aspect ratio

[robert-king]

plunkr not working,

but avatars are having their aspect ratios changes (cards and lists):

<img matListAvatar src="..." alt="...">

If my profile pictures aren't square, they get crushed/distorted into a different aspect ratio.

I'm on latest chrome on mac, using material 2.00-beta.12

The plunker's have been fixed, could you provide a reproduction as I am not quite sure what you are seeing.

[robert-king]

plunker stil doesn't work for me:

e.g. click the edit in plunker button on https://material.angular.io/components/list/overview

[robert-king]

Here is an example:

<mat-list role="list">
  <mat-list-item role="listitem">
    <img mat-list-avatar src="https://upload.wikimedia.org/wikipedia/commons/9/93/Denali_National_Park_Polychrome_Mountains_Wide_17350px.jpg" alt="...">
    Item with distorted avatar if not perfectly square.
    </mat-list-item>
</mat-list>

I guess can use something like:

.example-header-image {
  background-image: url('https://material.angular.io/assets/img/examples/shiba1.jpg');
  background-size: cover;
}

but would be nice if the list-avatar etc had the option to be automatically using cover

[robert-king]

actually it's quite hard using css background-image: url(..), because to get my images from the server with security, i need to use bearer tokens to get the image (e.g. use auth interceptor), and then I need to turn the blob into a link, sanatize / bypass security, etc etc. I created a pipe which works on [src], would have been quite nice to just use avatar & [src].

[odahcam]

I think that what ur trying to say is that avatars does not looks good if they're not a square image.

The list-avatar really distorts the image to get some squared picture.

This could be an issue, idk, but is really awful to see that distorted images.

[robert-king]

yeah, aspect ratio is changed to 1:1, which looks really bad unless you have a square image.

[robert-king]

i think something that would be useful is a circular image component that displays a circular image thats centered e.g.
<mat-circle-img [src]="..">
and it would have to use background: cover, or do it's own calculations to centre the image.
