Detailed Description

One of a number of interfaces (all starting with nsISVGRenderer*) to be implemented by an SVG rendering engine.

This interface serves as a factory for rendering engine-related objects. Each rendering engine needs to make available an nsIRenderer-object with a contract id of the form "@mozilla.org/svg/renderer;1?tech=NAME".

Engines implemented at the moment include an ms windows gdi+ engine ("@mozilla.org/svg/renderer;1?tech=GDIPLUS") and a (somewhat) cross-platform libart engine ("@mozilla.org/svg/renderer;1?tech=LIBART").

Member Function Documentation

nsISVGRendererPathGeometry nsISVGRenderer::createPathGeometry (  in nsISVGPathGeometrySource  src  )

Create a rendering engine-native path geometry object for the source object given by 'src'. Parameters: src  The source object describing the path for which this object is being created. Returns: A rendering engine-native path geometry object.

nsISVGRendererGlyphMetrics nsISVGRenderer::createGlyphMetrics (  in nsISVGGlyphMetricsSource  src  )

Create a rendering engine-native glyph metrics object for the source object given by 'src'. Parameters: src  The source object describing the glyph for which this metrics object is being created. Returns: A rendering engine-native glyph metrics object.

nsISVGRendererGlyphGeometry nsISVGRenderer::createGlyphGeometry (  in nsISVGGlyphGeometrySource  src  )

Create a rendering engine-native glyph geometry object for the source object given by 'src'. Parameters: src  The source object describing the glyph for which this object is being created. Returns: A rendering engine-native glyph geometry object.

nsISVGRendererCanvas nsISVGRenderer::createCanvas (  in nsIRenderingContext  ctx, in nsIPresContext  presContext, [const] in nsRectRef  dirtyRect )

Create a rendering engine-native canvas object for the Mozilla-native rendering context 'ctx' and presentation context 'presContext'. Parameters: ctx  Mozilla-native rendering context. presContext  Presentation context. dirtyRect  Area that the canvas should cover. Returns: A rendering engine-native canvas object.

nsISVGRendererRegion nsISVGRenderer::createRectRegion (  in float  x, in float  y, in float  width, in float  height )

Create a rendering engine-native region object for the given axis-aligned rectangle. Parameters: x  X-coordinate of rectangle (pixels). y  Y-coordinate of rectangle (pixels). width  Width of rectangle (pixels). height  Height of rectangle (pixels). Returns: A rendering engine-native region object.
