pub struct CreateRequest {
    pub damage: Damage,
    pub drawable: Drawable,

}
Expand description

Creates a Damage object to monitor changes to a drawable..

This creates a Damage object to monitor changes to a drawable, and specifies the level of detail to be reported for changes.

We call changes made to pixel contents of windows and pixmaps ‘damage’ throughout this extension.

Damage accumulates as drawing occurs in the drawable. Each drawing operation ‘damages’ one or more rectangular areas within the drawable. The rectangles are guaranteed to include the set of pixels modified by each operation, but may include significantly more than just those pixels. The desire is for the damage to strike a balance between the number of rectangles reported and the extraneous area included. A reasonable goal is for each primitive object drawn (line, string, rectangle) to be represented as a single rectangle and for the damage area of the operation to be the union of these rectangles.

The DAMAGE extension allows applications to either receive the raw rectangles as a stream of events, or to have them partially processed within the X server to reduce the amount of data transmitted as well as reduce the processing latency once the repaint operation has started.

The Damage object holds any accumulated damage region and reflects the relationship between the drawable selected for damage notification and the drawable for which damage is tracked.

§Fields

  • damage - The ID with which you will refer to the new Damage object, created by xcb_generate_id.
  • drawable - The ID of the drawable to be monitored.
  • level - The level of detail to be provided in Damage events.
