- 새 helpers/text-frame.ts — 정렬 · 가운데 맞춤 · 실제 글꼴 폭(굵게 · 기울임) · 회전 · 여러 줄 묶음 · 도각 칸 = 테두리 한 셈
- TextEntity 스침 · 고름 테두리 = 그 네 귀(여러 줄은 묶음 하나) · distanceTo = 테두리 안 0 · getBoundingBox 그대로
- 입력 칸 자리 · 폭 · 높이 = 같은 셈(여유 = 안쪽 여백) · 더블클릭 범위 = 테두리 + 집기 반경
- measureTextScreen 글꼴 받음 · 디버그 창구 textFrame(화면 네 귀)
- 리본 스침 = 바탕만(hover 기기만) · 켜짐 = 테두리 + 밑줄 · 누른 뒤 blur(초점 테두리 남음 막음)
- 시험 text-frame.test.ts 새로 · text-inplace-edit.test.ts 칸 폭 · 여백 · test_cad_host_tabs 줄바꿈 무관

Aislo B08 2D Drawing

This directory is maintained as part of the Aislo project and is not connected to an upstream Git repository. It provides the independent browser-based 2D drawing workspace used only by the B08 page.

The drawing engine is based on OpenWebCAD by Bert Verhelst and retains its MIT license notice in LICENSE.md and public/THIRD_PARTY_LICENSES.txt.

Aislo integration boundary

  • Business drawings enter the iframe only as same-origin JSON messages with type aislo:b08:load-drawing.
  • Browser-side DXF/DWG parsing is intentionally excluded.
  • DXF, DWG and PDF input/output are separate future modules and require a new dependency-license review before implementation.

Original project description

This is a React-based canvas drawing application that allows users to draw various shapes, such as lines, rectangles, and circles, on a fullscreen canvas. The application also includes features for selecting and erasing shapes, as well as exporting the drawing as an SVG file.
