Pysar.Avalonia

Avalonia integration for Pysar, a cross-platform report engine for .NET: avares:// application asset access, font registration and a scrollable, zoomable ReportView. It installs a DefaultReportPlatformHandler over AvaloniaAssetFileSystem for file and font access.

Setup

Assets are declared with ReportAsset; Pysar packages them as AvaloniaResource items read through avares://. Register from the application builder:

AppBuilder.Configure<App>()
    .UsePlatformDetect()
    .UsePysar();

The family string in the report has to be the Avalonia FontFamily string — fonts:Inter#Inter after WithInterFont or AddFontCollection with the key fonts:Inter, or avares://MyApp/Fonts#Ubuntu for an Avalonia resource folder — not a file path. A bare name (Ubuntu, Inter) is a system-font lookup; if TryGetGlyphTypeface substitutes the default face (Helvetica), Pysar treats that as a miss. AddFont still wins, and a library ReportAsset still needs one AddFont: the file is not copied into the head, and FontManager does not see it. A XAML FontFamily resource is not a registration. Styles stay Normal, Bold, Italic and BoldItalic. SemiBold, Light, stretch and per-character fallbacks are not shared, and Bold against a Regular-only file is not a real bold — the bytes that come back may be the regular face, because Avalonia's simulations are not kept on the SKTypeface. This bridge is Avalonia only. Console, the design-time preview, MAUI, WPF and Uno do not have FontManager and keep AddFont.

Showing a report

<pysar:ReportView Report="{Binding Report}"
                    ZoomMode="FitWidth"
                    Zoom="{Binding Zoom}"
                    EffectiveZoom="{Binding EffectiveZoom}"
                    CurrentPage="{Binding CurrentPage}"
                    PageSpacing="24" />

On the desktop, Ctrl or Cmd with the wheel zooms around the pointer, a plain wheel scrolls, and a double click magnifies and returns. PageBorderColor and PageBorderThickness frame each page; PageSpacing is the gap between pages and does not scale with the zoom. Bind EffectiveZoom to show the zoom percentage — Zoom holds what was asked for, not what the view settled on.

Trackpad pinch on macOS is handled natively, in MacPinchMonitor. Avalonia delivers no pinch gesture on that platform, so the zoom comes from an AppKit local event monitor for NSEventTypeMagnify, reached through the Objective-C runtime. It is a no-op everywhere else.

Printing

Printing uses the same vector PDF pipeline as export:

var printer = new AvaloniaReportPrinter(ReportViewRenderer.Instance);
await printer.PrintAsync(builtReport);

The report must already have Build() called.

## Avalonia fonts

**Report fonts can come from Avalonia `FontManager`.**
`UsePysar` installs a typeface fallback before your configuration. The family string in the report must be the Avalonia `FontFamily` string — `fonts:Inter#Inter` after `WithInterFont`, or `avares://MyApp/Fonts#Ubuntu` for a resource folder — not a file path. A bare name is a system-font lookup; if `TryGetGlyphTypeface` substitutes Helvetica, Pysar treats that as a miss.

`AddFont` still wins. A library `ReportAsset` still needs one `AddFont`: the file is not copied into the head, and `FontManager` does not see it. A XAML `FontFamily` resource is not a registration. Styles stay `Normal`, `Bold`, `Italic` and `BoldItalic`. This bridge is Avalonia only. Console, the design-time preview, MAUI, WPF and Uno keep `AddFont`.

## PDF export

**PDF/A-2b is an option of PDF, not another format.**
Pass `new PdfExportOptions { PdfA = true }` to `SavePdfAsync`, `RenderToPdfAsync`, `RenderToPdfBytesAsync`, or `IReportExportService.ExportAsync`. Skia writes the archival document setup: XMP `pdfaid` identification, a document UUID, and an sRGB output intent. It does not validate the file. A font Skia cannot embed still fails a checker, and the UUID makes those bytes non-reproducible. Existing overloads are unchanged.

## Images

**SVG is drawn from the bytes, not only from a `.svg` path.**
A stream or embedded source whose bytes start with `<svg` (optional XML declaration) is rendered as SVG. A decode or parse failure is recorded on the image cache, so the same bad bytes are not decoded again. Fixes #23.

## Rendering

**A built report may be rendered more than once, only sequentially.**
PDF and then page bitmaps, or a retry of the same export, is supported. Do not render one instance concurrently. `PageNumber` and `PageCount` are scratch written during the pass, and `OnPageChanged` runs again on every render.

## Uno

**Android report pages no longer depend on OpenGL ES.**
`UsePysar` sets `UseOpenGLOnSkiaAndroid` to false before the window is created. OpenGL ES draws image textures as opaque black, which hid every report page.

## Internal

- Host startup (Avalonia, MAUI, WPF, Uno) shares one installation sequence, `PysarInstallation`.
- `InternalsVisibleTo` for `Pysar.Avalonia` and `Pysar.Avalonia.Tests`.
