Pysar.Viewer

Framework-neutral viewer logic for Pysar, a cross-platform report engine for .NET: page geometry, zoom, tile planning and the tile cache. It depends on the core Pysar package and is the shared core behind every platform-specific ReportView control.

A built report renders as scrollable, zoomable pages, rasterised one visible tile at a time. Only the visible region is rasterised, so memory follows the size of the viewport rather than the zoom level.

This package is not referenced directly — it arrives transitively with a platform package, which supplies the actual UI control:

Platform package Control
Pysar.Maui .NET MAUI ReportView
Pysar.Avalonia Avalonia ReportView
Pysar.Wpf WPF ReportView (Windows only)
Pysar.Blazor Blazor <ReportView> component

The properties are the same on every platform. PageBorderColor and PageBorderThickness frame each page, which is what tells a page from the surface behind it when both are light; the line is drawn outside the paper, so the report itself is never covered by it. PageSpacing is the gap between two pages, in device independent units — it does not scale with the zoom, so the gap looks the same however far in the reader is.

A fit mode resolves to a factor only the control knows, so bind EffectiveZoom to show the percentage: Zoom holds what was asked for, not what the view settled on.

## Zoom & gestures

**Trackpad wheel events are now aggregated into a single gesture.**
Wheel events are timestamped and grouped using a new `WheelGestureGap`, and the wheel
anchor in `ReportView` is kept persistent for the duration of the gesture instead of
being recomputed per event.

**Sub-threshold pinch frames are deferred.**
`GestureModel.PinchByStep` / `PinchByScale` now report whether the change actually
reached the `ZoomModel`. Small frames are accumulated and only written once they exceed
`ZoomStepThreshold`. This fixes the visual drift between the model zoom and the rendered
pages during slow pinches.

Added tests covering the accumulation behaviour and confirming that presenter and page
layout do not drift across many sub-threshold frames.

## Internal

- `InternalsVisibleTo` added for the WPF test assembly, enabling direct unit tests of
 internal `Pysar.Wpf` logic without widening the public API.
