- <description summary="crop and scale interface to a wl_surface">
- An additional interface to a wl_surface object, which allows the
- client to specify the cropping and scaling of the surface
- contents.
-
- This interface allows to define the source rectangle (src_x,
- src_y, src_width, src_height) from where to take the wl_buffer
- contents, and scale that to destination size (dst_width,
- dst_height). This state is double-buffered, and is applied on the
- next wl_surface.commit.
-
- The two parts of crop and scale state are independent: the source
- rectangle, and the destination size. Initially both are unset, that
- is, no scaling is applied. The whole of the current wl_buffer is
- used as the source, and the surface size is as defined in
- wl_surface.attach.
-
- If the destination size is set, it causes the surface size to become
- dst_width, dst_height. The source (rectangle) is scaled to exactly
- this size. This overrides whatever the attached wl_buffer size is,
- unless the wl_buffer is NULL. If the wl_buffer is NULL, the surface
- has no content and therefore no size. Otherwise, the size is always
- at least 1x1 in surface coordinates.
-
- If the source rectangle is set, it defines what area of the
- wl_buffer is taken as the source. If the source rectangle is set and
- the destination size is not set, the surface size becomes the source
- rectangle size rounded up to the nearest integer. If the source size
- is already exactly integers, this results in cropping without scaling.
-
- The coordinate transformations from buffer pixel coordinates up to
- the surface-local coordinates happen in the following order:
- 1. buffer_transform (wl_surface.set_buffer_transform)
- 2. buffer_scale (wl_surface.set_buffer_scale)
- 3. crop and scale (wl_viewport.set*)
- This means, that the source rectangle coordinates of crop and scale
- are given in the coordinates after the buffer transform and scale,
- i.e. in the coordinates that would be the surface-local coordinates
- if the crop and scale was not applied.
-
- If the source rectangle is partially or completely outside of the
- wl_buffer, then the surface contents are undefined (not void), and
- the surface size is still dst_width, dst_height.
-
- The x, y arguments of wl_surface.attach are applied as normal to
- the surface. They indicate how many pixels to remove from the
- surface size from the left and the top. In other words, they are
- still in the surface-local coordinate system, just like dst_width
- and dst_height are.
-
- If the wl_surface associated with the wl_viewport is destroyed,
- the wl_viewport object becomes inert.
-
- If the wl_viewport object is destroyed, the crop and scale
- state is removed from the wl_surface. The change will be applied
- on the next wl_surface.commit.
