Constructor Detail

ECGPanel

public ECGPanel(short[][] samples,
                int numberOfChannels,
                int nSamplesPerChannel,
                String[] channelNames,
                int nTilesPerColumn,
                int nTilesPerRow,
                float samplingIntervalInMilliSeconds,
                float[] amplitudeScalingFactorInMilliVolts,
                float horizontalPixelsPerMilliSecond,
                float verticalPixelsPerMilliVolt,
                float timeOffsetInMilliSeconds,
                int[] displaySequence,
                int width,
                int height)

Construct a component containing an array of tiles of ECG waveforms.

Parameters:

samples - the ECG data as separate channels

numberOfChannels - the number of channels (leads)

nSamplesPerChannel - the number of samples per channel (same for all channels)

channelNames - the names of each channel with which to annotate them

nTilesPerColumn - the number of tiles to display per column

nTilesPerRow - the number of tiles to display per row (if 1, then nTilesPerColumn should == numberOfChannels)

samplingIntervalInMilliSeconds - the sampling interval (duration of each sample) in milliseconds

amplitudeScalingFactorInMilliVolts - how many millivolts per unit of sample data (may be different for each channel)

horizontalPixelsPerMilliSecond - how may pixels to use to represent one millisecond

verticalPixelsPerMilliVolt - how may pixels to use to represent one millivolt

timeOffsetInMilliSeconds - how much of the sample data to skip, specified in milliseconds from the start of the samples

displaySequence - an array of indexes into samples (etc.) sorted into desired sequential display order

width - the width of the resulting component (sample data is truncated to fit if necessary)

height - the height of the resulting component (sample data is truncated to fit if necessary)

Method Detail

paintComponent

public void paintComponent(Graphics g)

Draw the data onto the supplied graphic with the specified background.

Overrides:

paintComponent in class JComponent

Parameters:

g - the graphic to draw into

main

public static void main(String[] arg)

For testing.

Display the specified sample values as an array of tiles in a window, and take a snapshot of it as a JPEG file.

Parameters:

arg - an argument selecting the input type ("RAW", "DICOM" or "SCPECG"), followed by either 8 more arguments, the raw data filename (2 bytes per signed 16 bit sample interleaved), the number of channels, the number of samples per channel, the number of tiles per column, the number of tiles per row, the sampling interval in milliseconds, the amplitude scaling factor in millivolts, and the time offset in milliseconds for the left edge of the display or 4 more arguments, the SCPECG or DICOM data filename, the number of tiles per column, the number of tiles per row, and the time offset in milliseconds for the left edge of the display
