Member Function Documentation

containerSize()

const SkSize & SkSVGDOM::containerSize

(

)

const

DEPRECATED: use getRoot()->intrinsicSize() to query the root element intrinsic size.

Returns the SVG dom container size.

If the client specified a container size via setContainerSize(), then the same size is returned.

When unspecified by clients, this returns the intrinsic size of the root element, as defined by its width/height attributes. If either width or height is specified in relative units (e.g. "100%"), then the corresponding intrinsic size dimension is zero.

setContainerSize()

void SkSVGDOM::setContainerSize

(

const SkSize &

containerSize

)

Specify a "container size" for the SVG dom.

This is used to resolve the initial viewport when the root SVG width/height are specified in relative units.

If the root dimensions are in absolute units, then the container size has no effect since the initial viewport is fixed.

    // TODO: inval
    fContainerSize = containerSize;
