/**
|
||||
* A subclass of <code>ImageWriteParam</code> for encoding images in
|
||||
* the BMP format.
|
||||
*
|
||||
* <p> This class allows for the specification of various parameters
|
||||
* while writing a BMP format image file. By default, the data layout
|
||||
* is bottom-up, such that the pixels are stored in bottom-up order,
|
||||
* the first scanline being stored last.
|
||||
*
|
||||
* <p>The particular compression scheme to be used can be specified by using
|
||||
* the <code>setCompressionType()</code> method with the appropriate type
|
||||
* string. The compression scheme specified will be honored if and only if it
|
||||
* is compatible with the type of image being written. If the specified
|
||||
* compression scheme is not compatible with the type of image being written
|
||||
* then the <code>IOException</code> will be thrown by the BMP image writer.
|
||||
* If the compression type is not set explicitly then <code>getCompressionType()</code>
|
||||
* will return <code>null</code>. In this case the BMP image writer will select
|
||||
* a compression type that supports encoding of the given image without loss
|
||||
* of the color resolution.
|
||||
* <p>The compression type strings and the image type(s) each supports are
|
||||
* listed in the following
|
||||
* table:
|
||||
*
|
||||
* <p><table border=1>
|
||||
* <caption><b>Compression Types</b></caption>
|
||||
* <tr><th>Type String</th> <th>Description</th> <th>Image Types</th></tr>
|
||||
* <tr><td>BI_RGB</td> <td>Uncompressed RLE</td> <td>{@literal <= } 8-bits/sample</td></tr>
|
||||
* <tr><td>BI_RLE8</td> <td>8-bit Run Length Encoding</td> <td>{@literal <=} 8-bits/sample</td></tr>
|
||||
* <tr><td>BI_RLE4</td> <td>4-bit Run Length Encoding</td> <td>{@literal <=} 4-bits/sample</td></tr>
|
||||
* <tr><td>BI_BITFIELDS</td> <td>Packed data</td> <td> 16 or 32 bits/sample</td></tr>
