Preserve scroll position during PDF page rendering

Added functionality to maintain the scroll position and viewport
center of the `.pdf-frame` container during PDF page rendering.
This ensures the user's view remains centered on the same content
after re-rendering, even if the canvas dimensions change.

Implemented logic to store the scroll position and viewport center
before rendering and restore them afterward using scaling factors
calculated from the canvas's old and new dimensions.

+# 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/EnvelopeViewer.razor` | **NEW** PDF.js-based viewer (`/envelope/{key}`). Replaces ReportViewer.razor. Simple read-only PDF viewing with zoom/navigation. |
+| `ReceiverUI/Pages/ReportViewer.razor` | **LEGACY** DevExpress-based signing page (`/receiver/{key}`). Still used for signature workflow. Will be deprecated. |
+| `ReceiverUI/wwwroot/js/pdf-viewer.js` | **NEW** PDF.js wrapper: rendering, zoom, pagination, mouse wheel control. |
+| `ReceiverUI/wwwroot/js/receiver-signature.js` | JS: checkbox overlay, signature pad (draw/type/image). |
+| `ReceiverUI/wwwroot/css/envelope-viewer.css` | **NEW** Styles for EnvelopeViewer.razor (external CSS, not inline). |
+| `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)
+```

+
+## EnvelopeViewer (NEW) — PDF.js Read-Only Viewer
+
+**Route:** `/envelope/{EnvelopeKey}`  
+**Purpose:** Simple, modern PDF viewing without signing functionality.  
+**Technology:** PDF.js 3.11.174 + custom JavaScript wrapper
+
+### Architecture
+
+**Blazor Component (`EnvelopeViewer.razor`):**
+- Fetches PDF via `DocumentService.GetDocumentAsync(EnvelopeKey)`
+- Converts to base64 data URL: `data:application/pdf;base64,{base64}`
+- Initializes PDF.js viewer via JSInterop with `DotNetObjectReference` for callbacks
+- Displays controls: Zoom In/Out, Page Navigation, Zoom percentage
+- CSS externalized to `envelope-viewer.css`
+
+**JavaScript (`pdf-viewer.js`):**
+```javascript
+window.pdfViewer = {
+    pdfDoc, canvas, ctx, scale, currentRenderTask,
+    dotNetReference, wheelEventAttached,
+    
+    initialize(canvasId, pdfDataUrl, dotNetRef),
+    renderPage(num),
+    attachWheelEvent(),  // Global Ctrl+Wheel zoom
+    zoomIn(), zoomOut(),
+    nextPage(), previousPage(),
+    dispose()
+}
+```
+
+**CSS (`envelope-viewer.css`):**
+- `.envelope-viewer-layout`: Full-height gradient background
+- `.envelope-action-bar`: Top bar with logo, title, controls (sticky)
+- `.pdf-frame`: Fixed-size white container (`calc(100vh - 200px)` × 90% width, max 1200px)
+- `.pdf-canvas`: `display: inline-block`, unlimited zoom, scrollable when exceeds frame
+- Modern glassmorphism design with gradients and shadows
+
+### Features
+
+1. **Unlimited Zoom:**
+   - Canvas size not restricted by `max-width`
+   - Frame stays fixed, scroll bars appear automatically
+   - `text-align: center` for small sizes, full scroll for zoomed views
+
+2. **Global Mouse Wheel Zoom:**
+   - Event listener on `document.body` (works anywhere on page)
+   - `Ctrl + Mouse Wheel` triggers `zoomIn()`/`zoomOut()`
+   - Calls `dotNetReference.invokeMethodAsync('OnZoomChanged', scale)` to update Blazor UI
+   - `{ passive: false }` to enable `preventDefault()`
+
+3. **Render Task Cancellation:**
+   - Stores `currentRenderTask` to cancel previous render if new one starts
+   - Catches `RenderingCancelledException` to avoid console errors
+   - Queue system (`pageNumPending`) for rapid page changes
+
+4. **Responsive Design:**
+   - Desktop: 90% width, 1200px max
+   - Mobile: 95% width, adjusted heights
+   - Adaptive padding and font sizes
+
+### Flow
+
+1. **Component Load:**
+   ```csharp
+   OnInitializedAsync():
+     - Fetch PDF bytes
+     - Convert to base64 data URL
+     - Set _isLoading = false
+   
+   OnAfterRenderAsync():
+     - Create DotNetObjectReference
+     - JSRuntime.InvokeAsync("pdfViewer.initialize", canvasId, pdfDataUrl, dotNetRef)
+     - Update _totalPages, _currentPage, _pdfLoaded
+   ```
+
+2. **User Interaction:**
+   - Button clicks ? `ZoomIn()`/`ZoomOut()` ? `JSRuntime.InvokeVoidAsync("pdfViewer.zoomIn")`
+   - Ctrl+Wheel ? JS `attachWheelEvent()` ? `dotNetRef.invokeMethodAsync('OnZoomChanged')`
+   - Page buttons ? `NextPage()`/`PreviousPage()` ? `JSRuntime.InvokeAsync("pdfViewer.nextPage")`
+
+3. **Cleanup:**
+   ```csharp
+   DisposeAsync():
+     - JSRuntime.InvokeVoidAsync("pdfViewer.dispose")
+     - _dotNetRef?.Dispose()
+   ```
+
+### Key Differences from ReportViewer
+
+| Feature | EnvelopeViewer (NEW) | ReportViewer (LEGACY) |
+|---------|----------------------|------------------------|
+| Technology | PDF.js + Canvas | DevExpress XtraReports |
+| Route | `/envelope/{key}` | `/receiver/{key}` |
+| Purpose | Read-only viewing | Signature workflow |
+| Dependencies | PDF.js CDN | DevExpress NuGet packages |
+| Zoom | Unlimited, smooth | Report viewer default |
+| Mouse Wheel | Custom Ctrl+Wheel | Browser default |
+| File Size | Minimal (JS + CSS) | Heavy (DX libs) |
+| Maintenance | Simple, standard web | Complex, vendor-specific |
+
+---
+
+## ReceiverUI Signing Flow (ReportViewer.razor — LEGACY)
+
+### 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
+```
+
+---
+
+## NuGet Packages in ReceiverUI
+
+| Package | Version | Purpose |
+|---|---|---|
+| `DevExpress.Blazor.Reporting.Viewer` | 25.2.3 | DxReportViewer (LEGACY, used in ReportViewer.razor) |
+| `DevExpress.Blazor.PdfViewer` | 25.2.3 | PDF viewer (not used in EnvelopeViewer) |
+| `DevExpress.Drawing.Skia` | 25.2.3 | Drawing backend |
+| `itext` | 8.0.5 | PDF stamping (iText7) |
+| `SkiaSharp.*` | 3.119.1 | WASM native rendering |
+
+**External CDN (EnvelopeViewer):**
+- PDF.js 3.11.174 (via `https://cdnjs.cloudflare.com/ajax/libs/pdf.js/3.11.174/pdf.min.js`)
+- PDF.js Worker (`pdf.worker.min.js`)
+
+---
+
+## 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 |
+| **PDF.js: `display: flex` on `.pdf-frame`** | **Prevents left-edge scroll when canvas exceeds container** |
+| **PDF.js: `max-width: 100%` on canvas** | **Limits zoom; user expects unlimited zoom capability** |
+| **Mouse wheel on `.pdf-frame` only** | **Only works when mouse over PDF; should work anywhere on page** |
+
+---
+
+## 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 |
+| **11** | **2025-01-XX** | **Created EnvelopeViewer.razor (`/envelope/{key}`) with PDF.js 3.11.174** |

+
+A4 boyutlar? DX units cinsinden: Geni?lik = 827, Yükseklik = 1169

+
+## 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)

+
+### 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.

+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+## Getting Started

+
+### General Usage
+
+#### Using Open Iconic's SVGs
+
+We like SVGs and we think they're the way to display icons on the web. Since Open Iconic are just basic SVGs, we suggest you display them like you would any other image (don't forget the `alt` attribute).
+
+```
+<img src="/open-iconic/svg/icon-name.svg" alt="icon name">
+```
+
+#### Using Open Iconic's SVG Sprite
+
+Open Iconic also comes in a SVG sprite which allows you to display all the icons in the set with a single request. It's like an icon font, without being a hack.
+
+Adding an icon from an SVG sprite is a little different than what you're used to, but it's still a piece of cake. *Tip: To make your icons easily style able, we suggest adding a general class to the* `<svg>` *tag and a unique class name for each different icon in the* `<use>` *tag.*  
+
+```
+<svg class="icon">
+  <use xlink:href="open-iconic.svg#account-login" class="icon-account-login"></use>
+</svg>
+```
+
+Sizing icons only needs basic CSS. All the icons are in a square format, so just set the `<svg>` tag with equal width and height dimensions.
+
+```
+.icon {
+  width: 16px;
+  height: 16px;
+}
+```
+
+Coloring icons is even easier. All you need to do is set the `fill` rule on the `<use>` tag.
+
+```
+.icon-account-login {
+  fill: #f00;
+}
+```
