Struct Attributes 

pub struct Attributes {
    pub records: Vec<Record>,
}

A parsed attribute list.

Fields

records: Vec<Record>

The records, in stored order.

Implementations

impl Attributes

pub fn parse(blob: &[u8]) -> Result<Self>

Parses a TextLayerAttributes blob.

pub fn to_bytes(&self) -> Vec<u8>

The blob, records in the same order (unchanged records give the same bytes).

pub fn get(&self, id: u32) -> Option<&[u8]>

The bytes of the first record with this id.

pub fn set(&mut self, id: u32, data: Vec<u8>)

Replaces the first record with this id, or appends one.

pub fn font_size(&self) -> Option<f64>

Font size in points.

pub fn bbox(&self) -> Option<[i32; 4]>

Text block bounding box in layer pixels (record 42: x0, y0, x1, y1).

pub fn set_bbox(&mut self, bbox: [i32; 4])

Sets record 42.

pub fn block_size(&self) -> Option<[i32; 2]>

Text block width and height in pixels (record 63).

pub fn quad(&self) -> Option<[i32; 8]>

Four corners in 1/100 px relative to the anchor (record 64).

pub fn balloon(&self) -> Option<u32>

The 1-based index of the balloon object the block sits in (record 45).

pub fn render_offscreen(&self) -> Option<u32>

Id of the offscreen CSP rendered the text into (record 50; 0 = render again).

pub fn clear_render_offscreen(&mut self)

Make CSP render the text again on opening (needed after changing it).

pub fn font(&self) -> Option<Font>

The font (record 57).

pub fn transform(&mut self, scale: f64, dx: f64, dy: f64)

Move and scale the geometry records (bbox, block size, quad).
