Pysar.Wpf

WPF integration for Pysar, a cross-platform report engine for .NET: pack URI and assembly manifest asset access, font registration, a scrollable, zoomable ReportView, and printing. It installs a DefaultReportPlatformHandler over WpfAssetFileSystem for file and font access.

Windows only. On macOS and Linux the package is not produced; the real WPF sources compile only under net10.0-windows.

Setup

Call UsePysar from Application.OnStartup:

protected override void OnStartup(StartupEventArgs e)
{
    base.OnStartup(e);
    this.UsePysar(pysar => pysar
        .AddFont("Fonts/Ubuntu-Regular.ttf", "Ubuntu")
        .AddFont("Fonts/Ubuntu-Bold.ttf", "Ubuntu", FontStyle.Bold));
}

Showing a report

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

Ctrl + wheel zooms around the pointer; a plain wheel scrolls; double-click toggles fit width and close-up. 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.

Printing

Printing uses the same vector PDF pipeline as export:

var printer = new WpfReportPrinter(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`.
