public class PictReader
extends FormatReader

PictReader is the file format reader for Apple PICT files. Most of this code was adapted from the PICT readers in JIMI (http://java.sun.com/products/jimi/index.html), ImageMagick (http://www.imagemagick.org), and Java QuickDraw.

Source code:

Trac, Gitweb

Field Detail

rowBytes

protected int rowBytes

Number of bytes in a row of pixel data (variable).

strips

protected Vector strips

Vector of byte arrays representing individual rows.

versionOne

protected boolean versionOne

Whether or not the file is PICT v1.

lookup

protected byte[][] lookup

Color lookup table for palette color images.

qtTools

protected LegacyQTTools qtTools

Helper reader in case this one fails.

Constructor Detail

PictReader

public PictReader()

Constructs a new PICT reader.

Method Detail

setLegacy

public void setLegacy(boolean legacy)

Control whether or not legacy reader (QT Java) is used.

get8BitLookupTable

public byte[][] get8BitLookupTable()
                            throws FormatException,
                                   IOException

Description copied from interface: IFormatReader

Gets the 8-bit color lookup table associated with the most recently opened image. If no image planes have been opened, or if IFormatReader.isIndexed() returns false, then this may return null. Also, if IFormatReader.getPixelType() returns anything other than FormatTools.INT8 or FormatTools.UINT8, this method will return null.

Specified by:

get8BitLookupTable in interface IFormatReader

Overrides:

get8BitLookupTable in class FormatReader

Throws:

FormatException

IOException

openBytes

public byte[] openBytes(int no,
               byte[] buf,
               int x,
               int y,
               int w,
               int h)
                 throws FormatException,
                        IOException

Description copied from interface: IFormatReader

Obtains a sub-image of the specified image plane into a pre-allocated byte array.

Specified by:

openBytes in interface IFormatReader

Specified by:

openBytes in class FormatReader

Parameters:

no - the image index within the file.

buf - a pre-allocated buffer.

x - X coordinate of the upper-left corner of the sub-image

y - Y coordinate of the upper-left corner of the sub-image

w - width of the sub-image

h - height of the sub-image

Returns:

the pre-allocated buffer buf for convenience.

Throws:

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

IOException - if there was a problem reading the file.

See Also:

IFormatReader.openBytes(int, byte[], int, int, int, int)

close

public void close(boolean fileOnly)
           throws IOException

Description copied from interface: IFormatReader

Closes the currently open file. If the flag is set, this is all that happens; if unset, it is equivalent to calling Closeable.close().

Specified by:

close in interface IFormatReader

Overrides:

close in class FormatReader

Throws:

IOException

initFile

protected void initFile(String id)
                 throws FormatException,
                        IOException

Description copied from class: 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 FormatReader

Throws:

FormatException - if a parsing error occurs processing the file.

IOException - if an I/O error occurs processing the file
