Xceed’s Guide to Combo Charts, Watermarks, Smarter Splitting, and Sharper PDF Output

Xceed Words for .NET 5.1 delivers a leap forward in document automation cutting boilerplate, boosting output fidelity, and scaling to real production pipelines. This release arms .NET developers with direct APIs for Combo Charts, one-line watermarks, deterministic document splitting, and more predictable PDF rendering. Here’s how these features empower your team to build faster, communicate clearer, and ship with confidence.

Combo Charts: Context-Rich Data in a Single Visual

Communicate multiple data series in one view with Combo Charts now native to Xceed Words 5.1. Blend column, line, and other chart types to tell a story that’s instantly clear to stakeholders.

Finance: Revenue bars with margin trend lines
Operations: Throughput bars with SLA compliance lines
Product analytics: Event counts with conversion-rate overlays

Outcome: Grasp trends and comparisons at a glance no more juggling multiple charts or manual overlays.

One-Line Watermarks: Granular, Automated Branding

Watermarking is now a one-liner. Instantly apply or remove watermarks at any step in your pipeline:

AddWatermark: Apply a watermark with a single call
RemoveWatermark: Strip watermarks for final, signed, or audience-specific versions

For precision, choose:

TextWatermark: For compliance labels like “Confidential,” “Draft,” or localized text always with brand-consistent typography
PictureWatermark: For logo marks with full control over opacity and scale

Benefits: Toggle compliance per environment, standardize branding, and automate removal for production outputs—no more manual edits or risk of leaking drafts.

Smarter Splitting: Deterministic, Automated Output

Break up large documents with DocX.Split and SplitCriteria no more manual cutting or error-prone scripts.

ByHeadings: Split by document outline (e.g., H1/H2 chapters) perfect for chapterized reports or per-recipient mail-merge outputs
BySections: Split on section boundaries ideal for documents with layout changes (margins, orientation, headers/footers)

Workflows unlocked: Publish per-chapter PDFs, automate per-audience packets, and ingest parts into CMS or approval systems with zero manual intervention.

Sharper PDF Output & Reliability Improvements

Automatic reset of Paragraph.DefaultLineRuleAuto prevents cross-document style side effects in multi-document flows.
“Exactly” line spacing preserved in PDF even for EndOfLine-only paragraphs ensuring alignment and pagination in dense layouts.

Result: More predictable, pixel-perfect PDFs and safer document automation at scale.

Practical Implementation Patterns

Watermark pipeline:
Draft build: AddWatermark(TextWatermark)
Review build: AddWatermark(PictureWatermark) (brand logo)
Final build: RemoveWatermark()
Post-generation splitting:
Generate full report → DocX.Split(SplitCriteria.ByHeadings) → Export each part to PDF
PDF regression checks:
Re-export complex docs with “Exactly” spacing → Validate pagination/alignment at scale

Xceed Words for .NET 5.1 reduces boilerplate utilities, increases output fidelity, and scales with real-world production needs. With direct APIs for charts, watermarks, and splitting plus more predictable PDF rendering your team spends less time fixing layouts and more time shipping features.
