|
||||
* Protocol for requesting fractional surface scales
|
||||
*
|
||||
* @section page_desc_fractional_scale_v1 Description
|
||||
*
|
||||
* This protocol allows a compositor to suggest for surfaces to render at
|
||||
* fractional scales.
|
||||
*
|
||||
* A client can submit scaled content by utilizing wp_viewport. This is done by
|
||||
* creating a wp_viewport object for the surface and setting the destination
|
||||
* rectangle to the surface size before the scale factor is applied.
|
||||
*
|
||||
* The buffer size is calculated by multiplying the surface size by the
|
||||
* intended scale.
|
||||
*
|
||||
* The wl_surface buffer scale should remain set to 1.
|
||||
*
|
||||
* If a surface has a surface-local size of 100 px by 50 px and wishes to
|
||||
* submit buffers with a scale of 1.5, then a buffer of 150px by 75 px should
|
||||
* be used and the wp_viewport destination rectangle should be 100 px by 50 px.
|
||||
*
|
||||
* For toplevel surfaces, the size is rounded halfway away from zero. The
|
||||
* rounding algorithm for subsurface position and size is not defined.

|
||||
*
|
||||
* An additional interface to a wl_surface object, which allows the
|
||||
* client to specify the cropping and scaling of the surface
|
||||
* contents.
|
||||
*
|
||||
* This interface works with two concepts: the source rectangle (src_x,
|
||||
* src_y, src_width, src_height), and the destination size (dst_width,
|
||||
* dst_height). The contents of the source rectangle are scaled to the
|
||||
* destination size, and content outside the source rectangle is ignored.
|
||||
* 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 local 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, then src_width and src_height must be integers, and the
|
||||
* surface size becomes the source rectangle size. This results in cropping
|
||||
* without scaling. If src_width or src_height are not integers and
|
||||
* destination size is not set, the bad_size protocol error is raised when
|
||||
* the surface state is applied.
|
||||
*
|
||||
* 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 (wp_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 src_x or src_y are negative, the bad_value protocol error is raised.
|
||||
* Otherwise, if the source rectangle is partially or completely outside of
|
||||
* the non-NULL wl_buffer, then the out_of_buffer protocol error is raised
|
||||
* when the surface state is applied. A NULL wl_buffer does not raise the
|
||||
* out_of_buffer error.
|
||||
*
|
||||
* If the wl_surface associated with the wp_viewport is destroyed,
|
||||
* all wp_viewport requests except 'destroy' raise the protocol error
|
||||
* no_surface.
|
||||
*
|
||||
* If the wp_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.
