Constructor Detail

PictReader

public PictReader()

Constructs a new PICT reader.

Method Detail

getDimensions

public Dimension getDimensions(byte[] stuff)
                        throws loci.formats.FormatException

Get the dimensions of a PICT file from the first 4 bytes after header.

Throws:

loci.formats.FormatException

open

public BufferedImage open(byte[] pix)
                   throws loci.formats.FormatException,
                          IOException

Open a PICT image from an array of bytes (used by OpenlabReader).

Throws:

loci.formats.FormatException

IOException

isThisType

public boolean isThisType(byte[] block)

Description copied from interface: loci.formats.IFormatReader

Checks if the given block is a valid header for this file format.

openBytes

public byte[] openBytes(int no,
               byte[] buf)
                 throws loci.formats.FormatException,
                        IOException

Description copied from interface: loci.formats.IFormatReader

Obtains the specified image from the current file into a pre-allocated byte array of (sizeX * sizeY * bytesPerPixel).

Parameters:

no - the image index within the file.

buf - a pre-allocated buffer.

Returns:

the pre-allocated buffer buf for convenience.

Throws:

loci.formats.FormatException - if there was a problem parsing the metadata of the file.

IOException - if there was a problem reading the file.

openImage

public BufferedImage openImage(int no)
                        throws loci.formats.FormatException,
                               IOException

Description copied from interface: loci.formats.IFormatReader

Obtains the specified image from the current file.

Specified by:

openImage in interface loci.formats.IFormatReader

Overrides:

openImage in class loci.formats.FormatReader

Throws:

loci.formats.FormatException

IOException

initFile

protected void initFile(String id)
                 throws loci.formats.FormatException,
                        IOException

Description copied from class: loci.formats.FormatReader

Initializes the given file (parsing header information, etc.). Most subclasses should override this method to perform initialization operations such as parsing metadata.

Overrides:

initFile in class loci.formats.FormatReader

Throws:

loci.formats.FormatException

IOException
