A context within which sequence information may be rendered. It
encapsulates the rendering direction, the size of the leading and
trailing (header/footer, left/right areas), scale and the currently
rendered symbols, features and region.

Method Details
-
getDirection
int getDirection()Gets the direction in which this context expects sequences to be rendered - HORIZONTAL or VERTICAL.- Returns:
- The Direction value
-
getScale
double getScale()Gets the scale as pixels per Symbol- Returns:
- The scale value
-
sequenceToGraphics
Converts a sequence index into a graphical coordinate. You will need to use this in conjunction with getDirection to correctly lay graphics out.- Parameters:
i
- Index within the sequence- Returns:
- Equivalent graphical position in pixels
-
graphicsToSequence
Converts a graphical position into a sequence coordinate. You will need to have used getDirection to decide whether to use the x or y coordinate.- Parameters:
d
- A pixel position- Returns:
- The corresponding sequence index
-
graphicsToSequence
Converts a graphical position into a sequence coordinate. This will use getDirection to decide whether to use the x or y coordinate.- Parameters:
point
- a point representing the position- Returns:
- the corresponding sequence index
-
getSymbols
The SymbolList that is currently rendered by this SequenceRenderContext.- Returns:
- The Sequence value
-
getFeatures
The features to render.- Returns:
- a FeatureHolder with the Features to render
-
getRange
The range of the SymbolList to render.- Returns:
- the RangeLocation specifying which indices (inclusive) to render
-
getLeadingBorder
Gets the LeadingBorder attribute of the SequenceRenderContext object. This represents the space between the beginning of the rendering area and the beginning of the sequence.- Returns:
- The LeadingBorder value
-
getTrailingBorder
Gets the TrailingBorder attribute of the SequenceRenderContext object. This represents the space between the end of the sequence and the end of the rendering area.- Returns:
- The TrailingBorder value
-
getFont
Gets the Font attribute of the SequenceRenderContext object- Returns:
- The Font value
