## org.biojava.bio.program.blast2html
Class SimpleAlignmentStyler

    java.lang.Object
      org.biojava.bio.program.blast2html.AbstractAlignmentStyler
          org.biojava.bio.program.blast2html.SimpleAlignmentStyler

    public class SimpleAlignmentStyler

extends AbstractAlignmentStyler

Simple implementation for specifying markup styles. Has 3 modes of operation: SHOW_ALL, SHOW_SAME & SHOW_DIFF.

SHOW_ALL - returns the default style for all given residues. SHOW_SAME - only returns a markup style if the styles for both characters are the same. SHOW_DIFF - only returns a markup style if the styles for both are different. Styles can be easily defined in two ways.
1. Add each style by calling `addStyle( poChar, poColour )` For example, `String oRed = "FFA2A2"; oStyler.addStyle( "-", oRed ); oStyler.addStyle( "N", oRed ); oStyler.addStyle( "A", oRed ); oStyler.addStyle( "T", oRed ); oStyler.addStyle( "C", oRed ); oStyler.addStyle( "G", oRed );`

2. Alternatively the styles could be specified in a java properties file and loaded by calling `readColourMapFromProperties( poFilename )`, or `readColourMap()` and setting the system property 'colourMap' to the correct filename.
This file should be in java properties format, mapping characters to colours, specified in HEX RGB. For example:

     # set everything red
     - = FFA2A2
     N = FFA2A2
     A = FFA2A2
     T = FFA2A2
     C = FFA2A2
     G = FFA2A2

Note this is simply character based, so if you want to colour gaps then you need to specify a colour for the gap character.

If no colour is specified for a character then it is uncoloured.

Field Detail

### SHOW_ALL

    public static int SHOW_ALL

  Return default styles

### SHOW_SAME

    public static int SHOW_SAME

  Only return if the two colour classes for query and subject are the same

### SHOW_DIFF

    public static int SHOW_DIFF

  As NORMAL except only return if the two colour classes for query and subject are the different

Constructor Detail

### SimpleAlignmentStyler

    public SimpleAlignmentStyler(int piStyle)

  Creates a new `SimpleAlignmentStyler` instance.

  The int flag should be one of SimpleAlignmentStyler.SHOW_ALL, SimpleAlignmentStyler.SHOW_SAME or SimpleAlignmentStyler.SHOW_DIFF.

  Parameters:
    `piStyle` - (one of SimpleAlignmentStyler.SHOW_SAME or SimpleAlignmentStyler.SHOW_DIFF).
  Throws:
    `IllegalArgumentException` - - if style not one of allowed values

Method Detail

### readColourMapFromProperties

    protected void readColourMapFromProperties(String poFileName)

  Setup styles from java property file.

  Parameters:
    `poFileName` - - the file name of the property file.

### readColourMap

    protected void readColourMap()

  Read the the properties file that specifies the character/colour mapping. The location of the property file is specified by the system property 'colourMap'.

### getStyle

    public void getStyle(String poFirst,
                         String poSecond,
                         String[] poStyleHolder)

  Returns the styles for the two aligned characters in the form of predefined font classes.

  Null is acceptable value for no style.

  Specified by:
    `getStyle` in class `AbstractAlignmentStyler`
  Parameters:
    `poFirst` - - the first char in the alignment
    `poSecond` - - the second char in the alignment
    `poStyleHolder` - - an array to hold the styles, [0] = first etc
