OfficeIMO.Html

Shared HTML behavior for every converter

Browse the HTML examples for source files, rendered previews, and downloads.

OfficeIMO.Html owns HTML parsing, resource policy, base-URI resolution, accessible structure, layout scenes, and direct image rendering. Word, Excel, PowerPoint, Markdown, and focused bridge packages reuse this owner instead of implementing separate web-content rules.

using OfficeIMO.Html;

HtmlConversionDocument source = HtmlConversionDocument.Parse(
    "<h1>Status</h1><p>Generated by OfficeIMO.</p>");
byte[] png = source.ToPng(new HtmlRenderOptions { ViewportWidth = 720 });

Outputs and projections

• Render directly to PNG, JPEG, TIFF, SVG, and lossless WebP.
• Create PDF output with OfficeIMO.Html.Pdf.
• Convert semantic content to Word and Markdown through their focused adapter packages.
• Add OfficeIMO.Html.Rtf only for HTML/RTF conversion.
• Add OfficeIMO.Mhtml for bounded MHT/MHTML load and save, and OfficeIMO.Mhtml.Pdf for archive-to-PDF conversion.
• Add OfficeIMO.Email.Image only when an email body must be rendered to images.
• Apply URL, media, size, node, and depth policies before untrusted web content enters a document workflow.
• Require a no-loss render when a static template must stay inside the declared contract; otherwise every unsupported value remains visible through stable diagnostics.

The static renderer includes paged-media margin content, running elements, page counters, row and column subgrid, basic-shape clipping, vector SVG, tagged-PDF roles, and PDF bookmarks. JavaScript and live browser state remain an explicit browser-adapter concern rather than an automatic fallback.
