Aquileo | [InkMLLibJ] : channel attributes type and orientation wrong

Fri, 14 Aug 2009 14:55:51 -0000

When defining channels with InkMLLibJ, the exported InkML is not conform with the schema. The problem affects the attributes "type" and "orientation" of the element "channel".

For example the following code :

final TraceFormat traceFormat = new TraceFormat();
final Channel chanX = new Channel("X", ChannelType.INTEGER);
chanX.setUnits("dev");
traceFormat.addChannel(chanX);
final Channel chanY = new Channel("Y", ChannelType.INTEGER);
traceFormat.addChannel(chanY);
chanY.setUnits("dev");
final Channel chanF = new Channel("F", ChannelType.DECIMAL);
chanY.setMin("0.0");
chanY.setMax("1.0");
traceFormat.addChannel(chanF);
final Channel chanOTx = new Channel("OTx", ChannelType.INTEGER);
traceFormat.addChannel(chanOTx);
chanOTx.setMin("-60");
chanOTx.setMax("60");
chanOTx.setUnits("deg");
final Channel chanOTy = new Channel("OTy", ChannelType.INTEGER);
traceFormat.addChannel(chanOTy);
chanOTy.setMin("-60");
chanOTy.setMax("60");
chanOTy.setUnits("deg");

gives the following output with InkMLLibJ :
<traceFormat id='fmt1'><channel name='X' units='dev' defaultValue='0' type='INTEGER' orientation='POSITIVE' /><channel name='Y' min='0.0' max='1.0' units='dev' defaultValue='0' type='INTEGER' orientation='POSITIVE' /><channel name='F' defaultValue='0' type='DECIMAL' orientation='POSITIVE' /><channel name='OTx' min='-60' max='60' units='deg' defaultValue='0' type='INTEGER' orientation='POSITIVE' /><channel name='OTy' min='-60' max='60' units='deg' defaultValue='0' type='INTEGER' orientation='POSITIVE' /></traceFormat>

When using the method Ink.toInkML() with Java 1.6, we get the following exception :
java.lang.ClassCastException: java.util.HashMap$Values cannot be cast to java.util.ArrayList

Aquileo | inkMLLibj: Trace.getTraceDataAsString() error

Fri, 22 Aug 2008 16:13:13 -0000

Module: inkMLLibj
Version: 0.5.0
Class: com.hp.hpl.inkml.Trace#getTraceDataAsString()
The method does some strange line count estimations in line 642 - 654 which results in insufficient data when writing a Trace into a XML file. See test class below.

public class Test
{
public static void main(String[] args)
{
Trace trace = new Trace();
trace.setAssociatedContext(Context.getDefaultContext());
float x = 1.23456789f;
float y = 1.23456789f;
for (int i = 0; i < 11; i++)
{
trace.addToTraceData("X", new float[] {x++});
trace.addToTraceData("Y", new float[] {y++});
}
String data[] = trace.getTraceDataAsString();
for (int i = 0; i < data.length; i++)
{
System.out.print(data[i]);
if (i < data.length -1 && !data[i].trim().endsWith(","))
{
System.out.print(" <-- Error: this must be the last line");
}
System.out.println();
}
}
}
