Implementations

impl InlineMaskRegion

pub fn inline_mask_data(&self) -> (Rectangle, Vec<u8>)

Get data for an inline mask region.

This returns the values in the reference coordinate space (from the parent region item). The mask location is represented by a left top corner position, and a size defined by a width and height.

The mask is held as inline data on the region, one bit per pixel, the most significant bit first pixel, no padding. If the bit value is 1, the corresponding pixel is part of the region. If the bit value is 0, the corresponding pixel is not part of the region.
