Constructor Detail

SvgGradientNode

public SvgGradientNode(@NonNull
                       com.android.ide.common.vectordrawable.SvgTree svgTree,
                       @NonNull
                       org.w3c.dom.Node node,
                       @Nullable
                       java.lang.String nodeName)

Method Detail

deepCopy

@NonNull
public SvgGradientNode deepCopy()

isGroupNode

public boolean isGroupNode()

Returns true the node is a group node.

copyFrom

protected void copyFrom(@NonNull
                        SvgGradientNode from)

We do not copy mSvgLeafNode, boundingBox, or mGradientUsage because they will be set after copying the SvgGradientNode. We always call deepCopy of SvgGradientNodes within a SvgLeafNode and then call setSvgLeafNode for that leaf. We calculate the boundingBox and determine the mGradientUsage based on the leaf node's attributes and reference to the gradient being copied.

dumpNode

public void dumpNode(@NonNull
                     java.lang.String indent)

Dumps the current node's debug info.

transformIfNeeded

public void transformIfNeeded(@NonNull
                              java.awt.geom.AffineTransform rootTransform)

Transforms the current Node with the transformation matrix.

flatten

public void flatten(@NonNull
                    java.awt.geom.AffineTransform transform)

writeXml

public void writeXml(@NonNull
                     java.io.OutputStreamWriter writer,
                     boolean inClipPath,
                     @NonNull
                     java.lang.String indent)
              throws java.io.IOException

Writes content of the node into the VectorDrawable's XML file.

Parameters:

writer - the writer to write the group XML element to

inClipPath - boolean to flag whether the pathData should be apart of clip-path or not

indent - whitespace used for indending output XML

Throws:

java.io.IOException

addGradientStop

public void addGradientStop(java.lang.String color,
                            java.lang.String offset,
                            java.lang.String opacity)

setGradientUsage

public void setGradientUsage(@NonNull
                             SvgGradientNode.GradientUsage gradientUsage)

setSvgLeafNode

public void setSvgLeafNode(@NonNull
                           com.android.ide.common.vectordrawable.SvgLeafNode svgLeafNode)

parseLocalTransform

protected void parseLocalTransform(@NonNull
                                   java.lang.String nodeValue)

getTree

protected void fillPresentationAttributes(java.lang.String name,
                                          java.lang.String value)

fillEmptyAttributes

public void fillEmptyAttributes(java.util.Map<java.lang.String,java.lang.String> parentAttributesMap)

getAttributeValue

public java.lang.String getAttributeValue(@NonNull
                                          java.lang.String attribute)

Returns a string containing the value of the given attribute. Returns an empty string if the attribute does not exist.

copyFrom
