Module vector_build 

New vector objects: lines and コマ枠 (frame) borders (from name-studio’s clip-core).

A line is written in the layout CSP 5 gives a pen or polyline object (92-byte header, 88-byte points; see docs/spec/05-vector.md), with the fields that are not decoded copied from a CSP-made object. A frame border copies the header and first point of a border CSP made (FrameTemplate) and sets the corners’ miter values, which CSP uses to draw the border’s outside edge.

Objects name their brush by BrushStyle.MainId, so the brush style id must exist in the file the data goes into: take it from an object of the same file (VectorObject::brush_style).

Structs

FrameTemplate

The layout of one コマ枠フォルダー border, taken from a CSP-made frame folder: its header and first point, whose undecoded fields new borders keep (header 96 bytes and points 88 bytes in CSP 5).

NewFrame

One panel of a コマ枠フォルダー: its outline (layer pixels) and the border’s full width.

NewVectorLine

A line to draw as a new vector object, in layer pixels.

Functions

shape_signature

A short fingerprint of lines’ shapes (points to the pixel, in order), to tell whether a vector layer still holds what was written into it.
