Methods
Modifier and Type	Method and Description
`void`	`endReadFromPngRaw()` This is called when the read for the line has been completed (eg for interlaced).
`static IImageLineFactory<ImageLineByte>`	`getFactory(ImageInfo iminfo)`
`int`	`getRowNumber()`
`void`	`readFromPngRaw(byte[] raw, int len, int offset, int step)` Extract pixels from a raw unlfilterd PNG row.
`void`	`setRowNumber(int rowNumber)`
`void`	`writeToPngRaw(byte[] raw)` Writes the line to a PNG raw byte array, in the unfiltered PNG format Notice that the first byte is the filter type, you should write it only if you know it.

    Description copied from interface: IImageLine
    
    Extract pixels from a raw unlfilterd PNG row. Len is the total amount of bytes in the array, including the first byte (filter type) offset and step (0 and 1 for non interlaced) are in PIXELS Notice that when step!=1 the data is partial, this method will be called several times

    Description copied from interface: IImageLine
    
    Writes the line to a PNG raw byte array, in the unfiltered PNG format Notice that the first byte is the filter type, you should write it only if you know it.

public void endReadFromPngRaw()
```
    Description copied from interface: IImageLine
    
    This is called when the read for the line has been completed (eg for interlaced). It's called exactly once for each line. This is provided in case the class needs to to some postprocessing.
