The canvas background as a CSS color string; omitted or empty for transparent

Reference

blockId

requiredstring · at-uri

The AT-URI of this block record

height

ref

The canvas height in pixels

Reference

shapes

ref

The shapes in the drawing as a sequence of shape block ids in z-order (later = on top)

Reference

title

ref

The name of the drawing

Reference

width

ref

The canvas width in pixels

Reference

#ellipse

object

An ellipse or circle (set rx == ry for a circle)

Properties

blockId

requiredstring · at-uri

The AT-URI of this block record

cx

ref

Center X coordinate in pixels

Reference

cy

ref

Center Y coordinate in pixels

Reference

fill

ref

Fill style as a CSS color string; omitted or empty for no fill

Reference

opacity

ref

Opacity from 0 to 1 (defaults to 1)

Reference

rotation

ref

Rotation in radians around (cx, cy) (defaults to 0)

Reference

rx

ref

X radius in pixels

Reference

ry

Reference

stroke

ref

Stroke style as a CSS color string; omitted or empty for no stroke

Reference

strokeWidth

ref

Stroke width in pixels (defaults to 1)

Reference

#group

object

A named collection of shape block ids — a tag that lets a set of shapes be referred to together (selected, named, toggled). Membership is order-independent; z-order comes from #main.shapes

Properties

blockId

requiredstring · at-uri

The AT-URI of this block record

name

ref

The display name of the group

Reference

shapes

ref

The set of member shape block ids

Reference

#image

object

A placed image — positions and sizes a page.corvus.contentBlocks#image within the drawing. The image asset itself lives in the referenced block (its blob, alt text, and aspect ratio); this variant only carries the placement

Properties

blockId

requiredstring · at-uri

The AT-URI of this block record

height

ref

Height in pixels

Reference

image

ref

Register whose value is the at-uri of the page.corvus.contentBlocks#image block to render

Reference

opacity

ref

Opacity from 0 to 1 (defaults to 1)

Reference

rotation

ref

Rotation in radians around the image's center (defaults to 0)

Reference

width

ref

Width in pixels

Reference

x

ref

Top-left X coordinate in pixels

Reference

y

ref

Top-left Y coordinate in pixels

Reference

#path

object

A vector path — a sequence of commands that map directly to canvas path operations. Commands are inline values in the sequence and have no stable identity across edits (editing a command means deleting and re-inserting it). Use #stroke instead for freehand brush traces.

Properties

blockId

requiredstring · at-uri

The AT-URI of this block record

commands

ref

The path commands as an RGA sequence of #pathCommand objects

Reference

fill

ref

Fill style as a CSS color string; omitted or empty for no fill

Reference

opacity

ref

Opacity from 0 to 1 (defaults to 1)

Reference

rotation

ref

Rotation in radians applied around (x, y) at render time (defaults to 0)

Reference

stroke

ref

Stroke style as a CSS color string; omitted or empty for no stroke

Reference

strokeWidth

ref

Stroke width in pixels (defaults to 1)

Reference

x

ref

Origin X offset applied to the path at render time (defaults to 0)

Reference

y

ref

Origin Y offset applied to the path at render time (defaults to 0)

Reference

#pathCommand

object

A single path command. Used inline as a value in a #path.commands sequence — NOT its own block, NOT addressable, no stable identity across edits

Properties

coords

array

Coordinate arguments; interpretation depends on op. Angles for the A command are encoded in milliradians (0 to 2π × 1000) so they fit an integer

itemsinteger

  • knownValues: M | L | C | Q | A | Z

#rect
