ObviousPDF.Json 1.5.0

ObviousPDF.Json

Generate standards-compliant, accessible PDF documents from JSON with zero dependencies.

ObviousPDF.Json is the JSON-to-PDF renderer for ObviousPDF. It accepts a JSON document conforming to the ObviousPDF JSON Schema and produces a tagged, accessible PDF binary. Requires the ObviousPDF core package.

Easy Accessibility (v1.2.0)

Make any JSON-to-PDF document accessible with a single property:

{
  "accessible": true,
  "title": "My Document",
  "language": "en-US",
  "pages": [
    {
      "elements": [
        { "type": "text", "text": "Hello, accessible world!", "x": 72, "y": 720 }
      ]
    }
  ]
}

With "accessible": true, the renderer automatically enables tagged PDF, PDF/UA-1 conformance, auto-tagging for text and images, standard font substitution, and correct form field structure placement. No structureTree section is required.

Use "structureTag": "H1" (or "H2", "BlockQuote", etc.) on any element to override the default /P auto-tag for richer document semantics.

Accessibility Report Generation (v1.3.0)

Get automated feedback on document accessibility:

{
  "accessible": true,
  "generateAccessibilityReport": true,
  "pages": [ ... ]
}

var result = PdfJsonRenderer.RenderWithReport(json, "output.pdf");
if (result.AccessibilityReport != null)
    Console.WriteLine(result.AccessibilityReport.ToString());

Or enable via renderer options:

var options = new PdfJsonRendererOptions { GenerateAccessibilityReport = true };
var renderer = new PdfJsonRenderer(options);
var result = renderer.RenderToFileWithReport(json, "output.pdf");

⚠️ Disclaimer: The automated accessibility reports and checks provided by ObviousPDF are intended solely to assist in the assessment of document accessibility. They are not a comprehensive accessibility audit. To confirm that WCAG or PDF/UA standards are fully met, it is recommended to have human assessment by an accessibility specialist.

Sister Projects

All three pipelines produce identical PDF output and share the same accessibility features. Set "accessible": true (JSON), accessible="true" (XML), or accessible,true (CSV) for automatic PDF/UA-1 compliance.
