Detailed Description

Cursor information.

Metadata to describe the position and appearance of a pointing device.

Examples: video-dsp-src.c, video-play-pull.c, video-play.c, video-src-alloc.c, video-src-fixate.c, video-src-reneg.c, and video-src.c.

Field Documentation

◆ id

uint32_t spa_meta_cursor::id

cursor id.

an id of 0 is an invalid id and means that there is no new cursor data

Examples: video-dsp-src.c, video-src-alloc.c, video-src-fixate.c, video-src-reneg.c, and video-src.c.

◆ flags

uint32_t spa_meta_cursor::flags

extra flags

◆ position

struct spa_point spa_meta_cursor::position

position on screen

Examples: video-dsp-src.c, video-play-pull.c, video-play.c, video-src-alloc.c, video-src-fixate.c, video-src-reneg.c, and video-src.c.

◆ hotspot

struct spa_point spa_meta_cursor::hotspot

offsets for hotspot in bitmap, this field has no meaning when there is no valid bitmap (see below)

Examples: video-dsp-src.c, video-src-alloc.c, video-src-fixate.c, video-src-reneg.c, and video-src.c.

◆ bitmap_offset

uint32_t spa_meta_cursor::bitmap_offset

offset of bitmap meta in this structure.

When the offset is 0, there is no new bitmap information. When the offset is >= sizeof(struct spa_meta_cursor) there is a struct spa_meta_bitmap at the offset.

Examples: video-dsp-src.c, video-play-pull.c, video-play.c, video-src-alloc.c, video-src-fixate.c, video-src-reneg.c, and video-src.c.
