Extracting Vector Line Art from PDF Datasheets for CAD Editors

TLDR

Hardware engineers who need to extract component pinouts or mechanical dimensions from PDF datasheets are often stuck taking blurry raster screenshots or redrawing shapes manually. GINEXYS PDF Processor intercepts PDF vector path streams, computes CTM matrix transformations, and packages resolved SVG vectors to transmit directly to GINEXYS Schema Editor via OS IPC.

The Search Query: PDF Vector Line Art Extraction

Engineers search for:

• "extract vector paths from pdf datasheet javascript"
• "pdf vector line art to svg converter for cad"
• "extract vector shapes from pdf and send over ipc"

Intercepting PDF Vector Stream Operators

PDF Processor parses drawing operators (moveto, lineto, rect, closepath) from PDF page streams, applying Current Transformation Matrix (CTM) transformations to convert point units into normalized canvas coordinates.

// Resolving vector line segments and closed rects in analyzePanel.js
const hSegs = pageData.hSegs; // Horizontal line segments
const vSegs = pageData.vSegs; // Vertical line segments
const rects = pageData.closedRects; // Closed vector rectangles
console.log(Detected ${hSegs.length + vSegs.length} wire segments and ${rects.length} component boxes.);

Rule of thumb: extract CTM matrix transformations directly from the vector stream rather than rasterizing pages into PNG images.

Serializing CAD Vectors into Classified SVG Envelopes

The extracted geometry is formatted into an SVG document with classified data-geo-class attributes:

<svg viewBox="0 0 800 600" xmlns="http://www.w3.org/2000/svg">
  <!-- Classified wire vector line -->
  <line x1="120" y1="45" x2="300" y2="45" stroke="#333" data-geo-class="wire" />
  <!-- Classified IC component box -->
  <rect x="300" y="30" width="80" height="120" stroke="#333" data-geo-class="component" />
</svg>

Transmitting Geometry via OS IPC Bridge

With one click in analyzePanel.js, PDF Processor sends the SVG payload over CwsBridge to open Schema Editor automatically:

// Send vectors over CwsBridge IPC
window.CwsBridge.send('cws:tool:launch', { toolId: 'svg_wiring', focusAfterLaunch: true }, 'os');
const pointerId = await window.CwsBridge.requestStore(svgPayload, 'svg-vector');

Conclusion

Vector geometry extraction eliminates manual tracing, allowing CAD engineers to import clean vector schematics directly from PDF datasheets.
