Fixes in this release
| Key | Category | Summary |
|---|---|---|
| TOTALNET‑283 | Bug | [Conversion] Cannot trigger conversion.Convert() method |
| TOTALNET‑341 | Bug | [Viewer] GroupDocs.Viewer.Exceptions.GroupDocsViewerException: ‘CAD document rendering failed’ during rendering DXF file |
| TOTALNET‑351 | Bug | [Conversion] Converting certain HTML to PDF ignores ’nowrap’ rules in HTML table .NET |
TOTALNET‑283 — Conversion warmup optimization
In context of this issue we analyzed the ways to warm up the process when running GroupDocs.Conversion and GroupDocs.Viewer and applied the following optimizations:
| Approach | Result |
|---|---|
| Parallelize viewer warmups | Dropped viewer phase from ~3,500 ms to ~2,100 ms |
| Parallelize conversion with viewers too | Saved another ~1,100 ms — conversion now overlaps with viewers |
Multi-stage Dockerfile with aspnet runtime image | Smaller image, faster builds (17 s vs 92 s) |
| ReadyToRun pre-compilation | Reduced JIT overhead ~30–40 % |
What actually worked:
- Removed redundant warmup step — the “view converted PDF” step duplicated the PDF viewer warmup.
- Full parallelization — all 5 steps (conversion + 4 viewers) run concurrently via
Task.WaitAll. - ReadyToRun + runtime image —
dotnet publishwith-p:PublishReadyToRun=trueinstead ofdotnet runon SDK image.
Final result: 5,628 ms → 2,173 ms (61 % faster).
The remaining ~2,170 ms is the hard floor — libraries and font initialization inside GroupDocs.Viewer and GroupDocs.Conversion that runs once per process and cannot be cached or moved to build time.
TOTALNET‑341 — DXF rendering failure (partial fix)
This version includes a partial fix for the reported issue. Rendering of certain DXF files now works correctly when a valid license is configured. The fix resolves the licensing validation path but does not yet cover trial-mode rendering. In upcoming releases we will extend support to trial mode and complete the DXF rendering improvements.
TOTALNET‑351 — HTML-to-PDF nowrap handling
The original stylesheet used on the pre-conversion step employed a “force everything to fit” approach that overrode all cell wrapping with !important rules, which led to formatting issues in the final PDF file.
Solution: Reworked the stylesheet to defer to inline styles and properly handle nowrap rules already defined in the HTML.
Testing improvements: Previously, tests only checked the final document structure without verifying table formatting. This issue is now covered with visual tests that check the output, significantly reducing the chance of regression.
