Class PixelMask

java.lang.Object
  apollo.gui.genomemap.PixelMask

All Implemented Interfaces:

PixelMaskI

public class PixelMask
extends java.lang.Object
implements PixelMaskI

Class which records which pixels in a tier have been drawn already, used in drawing optimisation. The yindex in these methods corresponds to a given "tier" that is being masked. Separate masks are tracked for each tier.

Field Summary

protected static org.apache.log4j.Logger

logger

Constructor Summary

PixelMask(int levels, int size)
levels is the number of vertical levels/tiers size is the maximum x coord

Method Summary

boolean	isCompletelyObscured(int start, int stop, int yindex) start and stop are for x coords, yindex corresponds to vertical level Returns true if the range of xcoords in the yindex level is completely masked out
void	setPixelRangeState(int start, int stop, boolean state, int yindex) start and stop are for x coords, state is to set to toggle mask, yindex corresponds to vertical level
void	setPixelState(int pix, boolean state, int yindex)
java.lang.String	toString()
