Struct PolySegmentRequest

pub struct PolySegmentRequest<'input> {
    pub drawable: u32,
    pub gc: u32,
    pub segments: Cow<'input, [Segment]>,
}

draw lines.

Draws multiple, unconnected lines. For each segment, a line is drawn between (x1, y1) and (x2, y2). The lines are drawn in the order listed in the array of xcb_segment_t structures and does not perform joining at coincident endpoints. For any given line, a pixel is not drawn more than once. If lines intersect, the intersecting pixels are drawn multiple times.

TODO: include the xcb_segment_t data structure

TODO: an example

Fields

• drawable - A drawable (Window or Pixmap) to draw on.
• gc - The graphics context to use.

TODO: document which attributes of a gc are used

• segments_len - The number of xcb_segment_t structures in segments.
• segments - An array of xcb_segment_t structures.

Errors

• Drawable - The specified drawable does not exist.
• GContext - The specified gc does not exist.
• Match - TODO: reasons?

Fields

drawable: u32

gc: u32

segments: Cow<'input, [Segment]>
