<DL>
|
|
<DD>Performs filtering on a row of an image. This method may be

overridden in order to provide a custom algorithm for choosing

|
the filter type for a given row.
|
|
|
|
<p> The method is supplied with the current and previous rows
|
|
of the image. For the first row of the image, or of an
|
|
interlacing pass, the previous row array will be filled with
|
|
zeros as required by the PNG specification.
|
|
|
|
<p> The method is also supplied with five scratch arrays.
|
|
These arrays may be used within the method for any purpose.
|
|
At method exit, the array at the index given by the return
|

value of the method should contain the filtered data. The
|
|
return value will also be used as the filter type.
|
|
|
|
<p> The default implementation of the method performs a trial
|
|
encoding with each of the filter types, and computes the sum of
|
|
absolute values of the differences between the raw bytes of the
|
|
current row and the predicted values. The index of the filter
|
|
producing the smallest result is returned.
|
|
|
|
<p> As an example, to perform only 'sub' filtering, this method
|
|
could be implemented (non-optimally) as follows:
|
|
|
|
<pre>
|
|
for (int i = bytesPerPixel; i < bytesPerRow + bytesPerPixel; i++) {
|
|
int curr = currRow[i] & 0xff;
|
|
int left = currRow[i - bytesPerPixel] & 0xff;
|
|
scratchRow[PNG_FILTER_SUB][i] = (byte)(curr - left);
|

|
return PNG_FILTER_SUB;

The filtered row will be returned as one of the entries
|
|
of this array. The returned filtered data should start

|
at index <code>bytesPerPixel</code>; The initial

|
<code>bytesPerPixel</code> bytes are not used.<DD><CODE>bytesPerRow</CODE> - The number of bytes in the image row.

This value will always be greater than 0.<DD><CODE>bytesPerPixel</CODE> - The number of bytes representing a single
