Provides a panel for generating design-time or run-time VCL objects for a SVG. Unlike the TRSSVGImage component, the TRSSVGPanel component does not draw the SVG using canvas operations. Rather, it generates the VCL controls to draw the SVG.

The TRSSVGPanel for the VCL is much more limited in capabilities and compatibility with the SVG specification than the FMX version. The limitations include no clipping, rotated and scaled controls may be clipped, and flickering. It is recommended to use the TRSSVGPanel only on tested SVGs to prevent errors.

Represents property ShowHint.

published property

SVGDocument

Specifies the SVG document to display in the control. The SVGDocument and SVGRootID properties control exactly which SVG document and which branch of the SVG document hierarchy to display.

protected property

SVGRoot

Represents property SVGRoot.

published property

SVGRootID

Specifies which node of the SVGDocument to draw as the top- level SVG document.

Use the SVGRootID property to display only a portion of the SVGDocument .

WrapMode

Specifies whether and how to resize, replicate, and position the SVG image for rendering the TRSSVGImage surface.

The WrapMode property should be one of the constants defined in the TSVGImageWrapMode type:

iwOriginal-- displays the SVG with its original dimensions.

iwFit-- best fit (keeping SVG proportions--the ratio between the width and height) for the TRSSVGImage rectangle. Default.

iwStretch--stretches the SVG to fill the entire rectangle of this TRSSVGImage component.

iwTile--tiles the TRSSVGImage image to cover the entire rectangle of the TRSSVGImage component.

iwCenter-- center the SVG inside the TRSSVGImage component
