From 344e884d93bc35a8011427963f39575e56a5418a Mon Sep 17 00:00:00 2001 From: Johan Klokkhammer Helsing Date: Wed, 14 Nov 2018 15:47:00 +0100 Subject: Add deprecated support for wl_scaler [ChangeLog][Compositor] Add deprecated support for the deprecated wl_scaler. Some clients are stuck on the unofficial Weston protocol wl_scaler instead of the standardized and stable wp_viewporter. This implements optional support for wl_scaler. This patch has been written to be easily removable in Qt 6, and touches a minimal amount of other code. The implementation can be tested using the new manual test compositor: tests/manual/wlscaler. Weston 1.11.1 has a demo client named weston-resizor, which can be used to test. Note that although newer versions of Weston also have weston-resizor, those versions use wp_viewporter instead of wl_scaler, so you really need 1.11.1 or earlier to test.

This does not affect any other objects, + wl_viewport objects included. + + + + + + + + + + Instantiate an interface extension for the given wl_surface to + crop and scale its content. If the given wl_surface already has + a wl_viewport object associated, the viewport_exists + protocol error is raised. + + + + + + + + + + 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.
