Clients can get thumbnails by supplying a desired width and height and
|
||
|
|
thumbnailing method::
|
||
|
|
|
||
|
|
=> GET /_matrix/media/r0/thumbnail/<server_name>
|
||
|

/<media-id>?width=<w>&height=<h>&method=<m> HTTP/1.1

|
||
|
|
|
||
|
|
<thumbnail>
|
||
|
|
|
||
|
|
The thumbnail methods are "crop" and "scale". "scale" tries to return an
|
||
|
|
image where either the width or the height is smaller than the requested
|
||
|
|
size. The client should then scale and letterbox the image if it needs to
|
||
|
|
fit within a given rectangle. "crop" tries to return an image where the
|
||
|
|
width and height are close to the requested size and the aspect matches
|
||
|
|
the requested size. The client should scale the image if it needs to fit
|
||
|
|
within a given rectangle.
