-# EnvelopeGenerator — Copilot Context Notes (English)
-
-## Purpose
-A digital document signing system. Senders upload PDFs and place signature annotation fields via PSPDFKit (EnvelopeGenerator.Web). Receivers open the document in a Blazor WASM viewer, confirm each signature field via a checkbox overlay, draw/type/upload their signature, and export the stamped PDF.
-
----
-
-## Solution Structure
-
-| Project | Target | Description |
-|---|---|---|
-| `EnvelopeGenerator.API` | net8.0 | ASP.NET Core Web API. Receiver auth (cookie), annotation reading, PDF serving. |
-| `EnvelopeGenerator.ReceiverUI` | net8.0 WASM | Blazor WebAssembly. Receiver UI. YARP proxies API calls. |
-| `EnvelopeGenerator.Web` | net7/8/9 | Razor Pages. Sender UI + PSPDFKit annotation placement. |
-| `EnvelopeGenerator.Application` | multi | MediatR CQRS handlers. |
-| `EnvelopeGenerator.Domain` | multi | Domain models, constants, interfaces. |
-| `EnvelopeGenerator.Infrastructure` | multi | EF Core repos, DB context. |
-| `EnvelopeGenerator.PdfEditor` | multi | iText7 utilities. NOT used in ReceiverUI flow. |
-| `EnvelopeGenerator.DependencyInjection` | multi | DI registration helpers. |
-| VB.NET projects (Service/Form/BBTests) | net462 | Legacy. Do NOT touch. |
-
----
-
-## Key Files
-
-| File | Purpose |
-|---|---|
-| `ReceiverUI/Pages/ReportViewer.razor` | Main receiver page. All signing logic. |
-| `ReceiverUI/wwwroot/js/receiver-signature.js` | JS: checkbox overlay, signature pad (draw/type/image). |
-| `ReceiverUI/wwwroot/fake-data/annotations.json` | Dev-mode fake annotations (YARP proxy target). |
-| `ReceiverUI/Models/AnnotationDto.cs` | Annotation position model. All properties non-nullable. |
-| `ReceiverUI/Services/AnnotationService.cs` | Fetches `List<AnnotationDto>` from API or fake-data. |
-| `ReceiverUI/Services/DocumentService.cs` | Fetches PDF bytes from API. |
-| `ReceiverUI/Services/AuthService.cs` | Manages receiver session cookie. |
-| `API/Controllers/AnnotationController.cs` | GET `api/Annotation/{key}` ? annotation list. |
-| `API/Controllers/DocumentController.cs` | GET `api/Document/{key}` ? PDF bytes. |

-## AnnotationDto — Coordinate System
-
-```
-Unit   : 1/100 inch (DX units) — DevExpress XtraReports native
-Origin : Top-left corner of page
-X      : increases rightward
-Y      : increases downward
-
-A4 in DX units: Width = 827, Height = 1169
-
-Conversions:
-  PSPDFKit (pt, top-left):      xDX = xPsPdf * (100/72)
-  GDPicture (pt, bottom-left):  yDX = (pageHeightPt - yGD - elemHeightPt) * (100/72)
-  DX ? PDF points:              pt  = dx * (72/100)
-```
-
----
-
-## ReceiverUI Signing Flow (ReportViewer.razor)
-
-### On Load (`OnInitializedAsync`)
-1. `AuthService.CheckEnvelopeAccessAsync` ? redirect to login if unauthorized
-2. `AnnotationService.GetAnnotationsAsync` ? fills `_annotations`
-3. `DocumentService.GetDocumentAsync` ? fills `_basePdfBytes` (real mode)
-4. `BuildFreshBaseReport()` ? `XtraReport` for `DxReportViewer`
-
-### Signature Popup
-- Tabs: Draw / Text / Image
-- Fields: full name (required), position (optional), place (required)
-- Saved to `_capturedSignature` record
-- If annotations exist ? popup closes ? JS checkbox overlays installed
-
-### JS Checkbox Overlay (`receiver-signature.js`)
-- `receiverSignature.installAnnotationCheckboxes(annotations, checkedIds, dotNetRef)`
-- One `.annot-sig-cb-wrapper` div per annotation, absolutely positioned over viewer scroll container
-- Position: `left = pageRect.left + ann.x * scaleX`, `top = pageRect.top + ann.y * scaleY`
-  - `scaleX = pagePixelWidth / 827`, `scaleY = pagePixelHeight / 1169`
-- Click ? `dotNetRef.invokeMethodAsync('OnAnnotationToggled', id, checked)`
-
-### Apply Signatures ("Unterschriften anwenden" — `SubmitSignaturesAsync`)
-
-**Real PDF mode (`_basePdfBytes` is set):**
-- Calls `StampSignaturesOnPdf` using **iText7** directly on PDF bytes
-- Coordinate conversion: `xPt = ann.X * (72/100)`, `yPt = pageHeight - ann.Y * (72/100) - sigHeight` (Y flip: DX top-down ? PDF bottom-up)
-- Returns stamped bytes ? loaded into new `XtraReport` with `XRPdfContent`
-- Viewer refreshed with `ViewerKey++`
-
-**Dev/fake mode (`_basePdfBytes` is null):**
-- Falls back to `AddSignatureAtAnnotation` (XtraReports DetailBand + BeforePrint counter)
-- This is intentionally left as a dev fallback only
-
-### Export
-- `reportViewer.ExportToAsync(ExportFormat.Pdf)`
-
----
-
-## StampSignaturesOnPdf — iText7 Implementation
-
-```csharp
-// Located in ReportViewer.razor @code section
-// Called by SubmitSignaturesAsync when _basePdfBytes is available
-
-static byte[] StampSignaturesOnPdf(
-    byte[] sourcePdfBytes, byte[] signatureImageBytes,
-    string signerFullName, string signerPosition, string signaturePlace,
-    IReadOnlyList<AnnotationDto> annotations)
-{
-    // Opens PDF with PdfReader/PdfWriter
-    // For each annotation:
-    //   pageNum = ann.Page (clamped to totalPages)
-    //   xPt = ann.X * (72f/100f)
-    //   imgBottomY = pageHeight - ann.Y * (72f/100f) - sigHeightPt  ? Y-axis flip
-    //   PdfCanvas.AddImageFittedIntoRectangle(imageData, rect, false)
-    //   Separator line at bottom of image
-    //   Canvas text block below separator (font: Helvetica 7pt, color: RGB(73,80,87))
-    // Returns stamped byte[]
-}
-```
-
----
-
-## BuildFreshBaseReport()
-
-```csharp
-// Real PDF mode:
-var report = new XtraReport();
-var detail = new DetailBand();
-report.Bands.Add(detail);
-detail.Controls.Add(new XRPdfContent { Source = _basePdfBytes, GenerateOwnPages = true });
-return report;
-
-// Dev/fake mode: returns pre-built report from ReportStorage
-```

-## Mistakes History — Do NOT Repeat
-
-| Mistake | Why Wrong |
-|---|---|
-| `BottomMarginBand` for per-page signatures | Repeats on every page; Y offset wrong |
-| `imageY = (page-1) * 1169 + ann.Y` | Inflates DetailBand; 35 pages ? 140 pages |
-| `e.Graph?.PrintingSystem` in BeforePrint | `Graph` not on `CancelEventArgs` |
-| `ctrl.Report?.PrintingSystem` | `PrintingSystem` not on `XtraReportBase` in WASM |
-| Adding stamp endpoint to `DocumentController` | Not needed; stamping is done client-side in ReceiverUI |
-| iText7 via API (server-side) | Unnecessary; iText7 runs fine in WASM directly |
-
----
-
-## DevExpress Article (2023-08-28) — Why It Does NOT Apply
-
-The article describes **X.509 cryptographic digital signatures** via `PdfDocumentSigner` + `Pkcs7Signer`.  
-Our use case is **visual/image stamping** at specific page coordinates — different problem, different API.  
-`XRPdfSignature` in the article requires pre-placed fields in the report designer, not runtime coordinates.

-
-## Change Log
-
-| Session | Date | Change |
-|---|---|---|
-| 1–3 | — | Core infrastructure: services, YARP proxy, JS overlay, signature pad |
-| 4 | — | `AddSignatureAtAnnotation` with BottomMarginBand — ? repeated on all pages |
-| 5 | — | `BeforePrint` + `e.Graph?.PrintingSystem` — ? compile error |
-| 6 | — | BeforePrint counter — ? correct pattern, wrong band |
-| 7 | — | Switched to DetailBand — ? correct band |
-| 8 | — | `(page-1)*1169+Y` offset — ? 35?140 page inflation |
-| 9 | — | Fixed: `BoundsF.Y = ann.Y` + counter; created COPILOT_CONTEXT.md |
-| 10 | — | Investigated DevExpress article — not applicable to our case |
-| 10 | — | Added iText7 to ReceiverUI; implemented `StampSignaturesOnPdf` — ? deterministic coordinates, no page count side effects |
-| 10 | — | Split COPILOT_CONTEXT.md into COPILOT_CONTEXT_EN.md and COPILOT_CONTEXT_TR.md |

-Y artar  : a?a??ya do?ru
-
-A4 boyutlar? DX units cinsinden: Geni?lik = 827, Yükseklik = 1169
-
-Dönü?ümler:
-  PSPDFKit (pt, sol-üst):      xDX = xPsPdf * (100/72)
-  GDPicture (pt, sol-alt):     yDX = (pageHeightPt - yGD - elemHeightPt) * (100/72)
-  DX ? PDF points:             pt  = dx * (72/100)
-  PDF Y ekseni çevirme:        imgBottomY = sayfaYüksekli?iPt - ann.Y*(72/100) - elemanYüksekli?iPt
-```

-
-## ReceiverUI ?mzalama Ak??? (ReportViewer.razor)
-
-### Sayfa Yüklenince (`OnInitializedAsync`)
-1. `AuthService.CheckEnvelopeAccessAsync` ? yetkisizse login sayfas?na yönlendir
-2. `AnnotationService.GetAnnotationsAsync` ? `_annotations` listesi dolar
-3. `DocumentService.GetDocumentAsync` ? `_basePdfBytes` dolar (gerçek mod)
-4. `BuildFreshBaseReport()` ? `XtraReport` olu?turulur, `DxReportViewer`'a verilir
-
-### `BuildFreshBaseReport()` Mant???
-```
-_basePdfBytes dolu ? XtraReport + DetailBand + XRPdfContent { GenerateOwnPages = true }
-_basePdfBytes bo? (ForceToUseFakeDocument=true) ? ReportStorage'dan LargeDatasetReport ?ablonu (XtraReport, designer'dan geldi?i gibi)
-```
-
-> NOT: `_basePdfBytes` dal? korunur (gerçek PDF modu). Dev ve test sunucusunda `PredefinedReport` (LargeDatasetReport) `XtraReport` olarak do?rudan kullan?l?r — PDF'e export ED?LMEZ.
-
-### ?mza Popup'? ("Unterschrift erstellen")
-- Sekmeler: Çizim / Yaz? / Resim
-- Alanlar: Ad soyad (zorunlu), pozisyon (opsiyonel), yer (zorunlu)
-- `_capturedSignature` record'una kaydedilir
-- Annotation varsa popup kapan?r ? JS checkbox overlay kurulur
-
-### JS Checkbox Overlay (`receiver-signature.js`)
-- `receiverSignature.installAnnotationCheckboxes(annotations, checkedIds, dotNetRef)` C#'tan ça?r?l?r
-- Her annotation için `.annot-sig-cb-wrapper` div'i, viewer scroll container'?na absolute olarak yerle?tirilir
-- **Koordinat hesab?:** `left = pageRect.left + ann.x * scaleX`, `top = pageRect.top + ann.y * scaleY`
-  - `scaleX = sayfaPixelGeni?li?i / 827`, `scaleY = sayfaPixelYüksekli?i / 1169`
-  - Bu koordinatlar sayfa-relatif ve do?ru çal???yor
-- T?klan?nca `dotNetRef.invokeMethodAsync('OnAnnotationToggled', id, checked)` ça?r?l?r
-
-### ?mza Uygulama ("Unterschriften anwenden" — `SubmitSignaturesAsync`)
-
-**Tek ortak yol (her iki mod):**
-- `SubmitSignaturesAsync` ? `BuildFreshBaseReport()` + `WireAnnotationSignatures(report, _capturedSignature)`
-- `WireAnnotationSignatures` ? `report.AfterPrint` olay?na abone olur
-- Belge olu?unca `report.PrintingSystem.Pages` dolu olur; her annotation için `Pages[ann.Page-1]` sayfas?na:
-  - `ImageBrick { Image = imza görseli, Rect = (ann.X, ann.Y, 230, 70), SizeMode = ZoomImage }`
-  - `TextBrick  { Text = bilgi metni, Rect = (ann.X, ann.Y+75, 230, 65) }`
-  - `Page.AddBrick(brick)` ile bas?l?r
-- Brick `Rect`'leri annotation `X`/`Y` (1/100 inch) ? checkbox overlay ile birebir ayn? koordinat, do?ru sayfa+konum
-- `ViewerKey++` ile viewer yenilenir
-
-**Gerçek PDF modu (`_basePdfBytes` dolu):** Yukar?daki ile ayn?; rapor `XRPdfContent`'ten olu?ur, brick'ler yine `AfterPrint` ile `PrintingSystem.Pages` üzerine bas?l?r.

-## GÖREV 1: ?mza Konum Hatas? (BUG) — ÇÖZÜLDÜ
-
-### Kullan?c?n?n ?ste?i
-Annotation'lardan okunan sayfa ve X/Y koordinatlar?na göre, t?pk? checkbox overlay'ler gibi, imzalar do?ru sayfa ve konumda görünsün. `_basePdfBytes` dal? korunsun; dev/test'te designer ile olu?turulan `PredefinedReport` `XtraReport` olarak do?rudan kullan?lmaya devam etsin (PDF'e export yok).
-
-### ÇÖZÜM (Oturum 12) ?
-`WireAnnotationSignatures` metodu, `report.AfterPrint` olay?nda `report.PrintingSystem.Pages[ann.Page-1].AddBrick(...)` ça??rarak imza görselini (`ImageBrick`) ve bilgi metnini (`TextBrick`) do?rudan hedef sayfaya, annotation `X`/`Y` (1/100 inch) konumunda basar.
-
-**Neden çal???r:**
-- `AfterPrint`, belge tamamen olu?tuktan sonra tetiklenir; `PrintingSystem.Pages` art?k gerçek/nihai sayfalar? içerir.
-- Sayfa indeksleme (`Pages[ann.Page-1]`) band veya veri-sat?r? tekrar?ndan **ba??ms?zd?r** ? `LargeDatasetReport`'un veri-ba?l? `detailBand1` sorununu tamamen atlar.
-- Brick `Rect` koordinatlar? raporun yerel 1/100 inch sistemindedir ? checkbox overlay ile birebir ayn?, do?ru konum.
-- Yeni sayfa eklenmedi?i için sayfa say?s? katlanmaz (35 sayfa ? 35 sayfa).
-
-**Derleme s?ras?nda ö?renilen API gerçekleri:**
-- `PrintOnPage` olay? `e.Page` VERMEZ (yaln?zca `PageIndex`/`PageCount`) ? brick eklenemez. Do?ru olay `AfterPrint` + `PrintingSystem.Pages`.
-- `Page` tipinde `InsertBrick` YOK; do?ru metot `Page.AddBrick(brick)` (brick'in `Rect`'i konumu belirler).
-- `ImageBrick.BorderStyle` tipi `BrickBorderStyle`'dir (`BorderDashStyle` de?il). Border için `Sides` + `BorderColor` kullan?ld?.
-
-### Denenen Eski Çözümler (ba?ar?s?z — referans)
-
-| Deneme | Yakla??m | Sonuç | Ba?ar?s?zl?k Sebebi |
-|---|---|---|---|
-| 1 | `BottomMarginBand` + `XRPictureBox`/`XRLabel` | Her sayfan?n alt?na ç?kt? | Band her sayfada tekrarlan?r, sayfa filtresi yok |
-| 2 | `BeforePrint` + `e.Graph?.PrintingSystem` | Derleme hatas? | `CancelEventArgs`'ta `Graph` yok |
-| 3–6 | `DetailBand` + `BeforePrint` counter | Yanl?? sayfa/konum | ?ablonun `detailBand1`'i veri sat?r? ba??na tetiklenir, sayfa ba??na de?il |
-| 7 | iText7 export/reload döngüsü | 35 ? 70 sayfa | Margin uyu?mazl???, `GenerateOwnPages` sayfalar? böldü |
-| 8 | Fake modda `BottomMarginBand` fallback | Her sayfan?n alt?nda | Koordinat yanl?? |
-
----
-
-## YAPILMAMASI GEREKENLER
-
-| Hata | Neden Yanl?? |
-|---|---|
-| `BottomMarginBand`/`DetailBand` ile sayfa-spesifik imza | Band veri-sat?r?/sayfa ba??na tekrarlan?r, koordinat kayar |
-| `BeforePrint` counter ile sayfa filtresi | Veri-ba?l? raporda sat?r ba??na tetiklenir, güvenilmez |
-| `PrintOnPage` ile brick ekleme | `e.Page` yok; brick eklenemez |
-| `Page.InsertBrick(...)` | Yok; do?ru metot `Page.AddBrick(...)` |
-| iText7 export+reload döngüsü | Margin uyu?mazl???ndan sayfa say?s? katlan?r |
-| ?ablonu PDF'e export edip `XRPdfContent`'e yükleme | ?stenmiyor; designer raporu do?rudan kullan?lmal? |
-| Stamplama için API endpoint ekleme | Gereksiz; brick'ler client'ta bas?l?r |

-## BEKLEYEN D??ER GÖREVLER (Sonraki Chat'te Yap?lacak)
-
-### 2. ?mza Arka Plan? Özelli?i
-?mza görselinin ve bilgilerinin kaplad??? alan kadar, yar? saydam hafif gri opak dikdörtgen arka plan ekle. Böylece imza ve bilgiler arka plandaki metinlerden etkilenmez ve okunur kal?r. (Art?k brick tabanl?: `ImageBrick`/`TextBrick`'in arkas?na bir arka plan `Brick` dikdörtgeni eklenebilir.)
-
-### 3. Checkbox Renk ve Stil ?yile?tirmesi
-Mevcut checkbox'lar?n rengi ve kenarl?klar? çok dikkat çekici. Koyu füme tonlar?nda, desenli, sade ve profesyonel görünümlü bir stil olsun. (`receiver-signature.js` ve ilgili CSS.)
-
-### 4. Sayfa Aç?l???nda Otomatik ?mza Popup'?
-Sayfa aç?l?r aç?lmaz imza popup'? ç?ks?n. "Kay?tl? hiç bir imzan?z yok, tan?mlay?n?z" mesaj? gösterilsin. Kullan?c? imzas?n? tan?mlamadan ilerleyemesin. Mevcut "Unterschrift erstellen" butonu "?mzay? de?i?tir" olarak güncellensin.
-
-### 5. Otomatik ?mza Uygulama
-Kullan?c? tüm checkbox'lar? onaylad??? anda imzalar otomatik olarak uygulanmaya ba?las?n (butona t?klamaya gerek kalmas?n). Sayfan?n üstünde imza say?s? ve imzalanmas? gereken sayfalar hakk?nda bilgi gösterilsin.
-
-### 6. Checkbox - DevExpress Toolbar Pozisyon Uyumsuzlu?u (BUG)
-- Checkbox'lar browser'?n boyut/konumuna neredeyse anl?k tepki veriyor
-- DevExpress toolbar de?i?ikliklerine geç tepki gösteriyor
-- Zoom de?i?ince bazen 2-3 PDF yan yana gelebiliyor; checkbox o konumda do?ru görünüyor ama iki PDF'in yan yana gelmesi kald?r?lmal?
-- `DocumentViewer.razor`'daki `DxDocumentViewer` + `DxDocumentViewerTabPanelSettings` bile?enleri daha uygun olabilir mi? De?erlendirmesi yap?lacak.
