IDynamicRenderer::get_ClipRectangle method (rtscom.h)

Article
02/22/2024

Gets or sets the clipping rectangle for the DynamicRenderer Class object.

This property is read/write.

Syntax

HRESULT get_ClipRectangle(
  RECT *prcClipRect
);

Parameters

prcClipRect

Return value

None

Remarks

The ClipRectangle property is set immediately and applies to the stroke that is being drawn. It differs from the IDynamicRenderer::DrawingAttributes Property property, which applies to the next stroke drawn. This allows the clip rectangle to grow as the stroke is drawn.

When calling the IDynamicRenderer::Refresh Method from within a Paint event handler, set the IDynamicRenderer::ClipRectangle Property to the Paint event's rectangle.

Note If the ClipRectangle is expanded in mid-stroke, then a IDynamicRenderer::Refresh Method call is required in order to display the new ink. This refresh call must be made every time new ink appears in a new area; however, doing so may cause performance problems when inking in the new area.
