Method Details

matchElement

RenderStyle[] matchElement(GeometryBuffer.GeometryType type,
 TagSet tags,
 int zoomLevel)

Matches a MapElement with the given parameters against this RenderTheme.

Parameters:

zoomLevel - the zoom level at which the way should be matched.

Returns:

matching render instructions

dispose

void dispose()

scaleTextSize

void scaleTextSize(float scaleFactor)

Scales the text size of this RenderTheme by the given factor.

Parameters:

scaleFactor - the factor by which the text size should be scaled.

transformBackwardKey

String transformBackwardKey(String key)

Transform internal key to tile source key. e.g. for lazy fetched tag values via tile source key. Use when tile source and internal keys have 1-1 relation.

Returns:

the backwards transformed tag key.

transformForwardKey

String transformForwardKey(String key)

Transform tile source key to internal key.

Returns:

the forward transformed tag key.

transformBackwardTag

Tag transformBackwardTag(Tag tag)

Returns:

the backwards transformed tag.

transformForwardTag

Tag transformForwardTag(Tag tag)

Transform tile source tag to internal tag.

Returns:

the forward transformed tag.
