Data Fields | |
| enum axoverlay_anchor_point | anchor_point |
| enum axoverlay_position_type | postype |
| gfloat | x |
| gfloat | y |
| gint | width |
| gint | height |
| gint | z_priority |
| enum axoverlay_colorspace | colorspace |
| gboolean | scale_to_stream |
This struct contains data used to create a new overlay.
| enum axoverlay_anchor_point axoverlay_overlay_data::anchor_point |
The anchor point for the overlay. The default is AXOVERLAY_ANCHOR_TOP_LEFT.
| enum axoverlay_colorspace axoverlay_overlay_data::colorspace |
The colorspace must be set to one of the constants in overlay_colorspace. Note that when using the palette colorspaces only the alpha channel has any effect (when rendering with cairo). The palette colors needs to be set manually by invoking dbus. The default is ARGB32.
| gint axoverlay_overlay_data::height |
The height of the overlay. It should be set to the size that the overlay should have on a stream of max resolution. Unless scale_to_stream is set to FALSE the size will later be scaled to the actual stream resolution.
| enum axoverlay_position_type axoverlay_overlay_data::postype |
The postion type. This parameter controls how the x and y parameters are interpreted. See documentation of position_type for details.
| gboolean axoverlay_overlay_data::scale_to_stream |
If this parameter is set to TRUE the size of the overlay will be scaled to match the resolution of the stream. If it is set to FALSE the developer is responsible for handling this in the adjustment_callback. The default is TRUE.
| gint axoverlay_overlay_data::width |
The width of the overlay. It should be set to the size that the overlay should have on a stream of max resolution. Unless scale_to_stream is set to FALSE the size will later be scaled to the actual stream resolution.
| gfloat axoverlay_overlay_data::x |
The x coordinate for the position of the top-left corner of the overlay.
| gfloat axoverlay_overlay_data::y |
The y coordinats for the position of the top-left corner of the overlay.
| gint axoverlay_overlay_data::z_priority |
The z priority of the overlay. An overlay with higher priority will be placed in front of an overlay with lower priority in case they overlay. The default is 0.
