# Step 6: PDF Export
|
|
|
|
Implement `PdfStatementService` in `src/Duempelkas.Infrastructure/Services/`.
|
|
|
|
## PDF Document Structure
|
|
|
|
Generate one PDF per account/year with the following sections:
|
|
|
|
### Header
|
|
- Account name (bold, large)
|
|
- Year (e.g., "Statement 2026")
|
|
- Generation date
|
|
|
|
### Opening Balance Section
|
|
- "Carryover from previous year: X.XX €"
|
|
|
|
### Ledger Table
|
|
- Columns: Date, Title, Type, Amount
|
|
- Rows sorted chronologically (oldest → newest)
|
|
- Type column shows "Income", "Expense", or "Transfer" (for linked entries)
|
|
- Transfer rows should include a note like "→ TargetAccountName" or "← SourceAccountName"
|
|
- Amount formatted as "1.234,56 €" (German locale)
|
|
|
|
### Summary Footer
|
|
1. "Carryover from previous year: X.XX €"
|
|
2. "Current year result: X.XX €" (sum of incomes minus sum of expenses)
|
|
3. "Final balance: X.XX €" (carryover + current year result)
|
|
|
|
## Implementation Details
|
|
- Use `QuestPDF.Fluent` API with `Document.Create(...)`.
|
|
- Set `QuestPDF.Settings.License = LicenseType.Community` in startup.
|
|
- Reuse `IBalanceQueryService.GetYearlySummaryAsync` and `IEntryService.GetEntriesAsync` to get the data — do NOT recalculate balances independently.
|
|
- Return `byte[]` from `GenerateYearlyStatementAsync`.
|
|
- Use A4 page size, reasonable margins, and professional typography.
|
|
|
|
## Conventions
|
|
- Keep the PDF layout in a single service method or split into private helper methods.
|
|
- Use `CultureInfo("de-DE")` for number/currency formatting.
