Constructor Detail

VectraReader

public VectraReader()

Constructs a new Vectra reader.

Method Detail

isThisType

public boolean isThisType(java.lang.String name,
                          boolean open)

Description copied from class: FormatReader

Checks if a file matches the type of this format reader. Checks filename suffixes against those known for this format. If the suffix check is inconclusive and the open parameter is true, the file is opened and tested with FormatReader.isThisType(RandomAccessInputStream).

Specified by:

isThisType in interface IFormatReader

Overrides:

isThisType in class FormatReader

open - If true, and the file extension is insufficient to determine the file type, the (existing) file is opened for further analysis.

getSeriesUsedFiles

public java.lang.String[] getSeriesUsedFiles(boolean noPixels)

Description copied from interface: IFormatReader

Returns an array of filenames needed to open the current series. If the 'noPixels' flag is set, then only files that do not contain pixel data will be returned. The first element in the array is expected to be the path passed to IFormatHandler.setId(String), if appropriate based upon 'noPixels'. The remaining elements are expected to be in a consistent order; if a directory listing is necessary to build the list then it should be sorted first.

Specified by:

getSeriesUsedFiles in interface IFormatReader

Overrides:

getSeriesUsedFiles in class FormatReader

openBytes

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

Overrides:

openBytes in class MinimalTiffReader

Parameters:

no - the plane index within the current series.

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.

java.io.IOException - if there was a problem reading the file.

See Also:

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

openThumbBytes

public byte[] openThumbBytes(int no)
                      throws FormatException,
                             java.io.IOException

Description copied from interface: IFormatReader

Obtains a thumbnail for the specified image plane from the current file, as a byte array.

Specified by:

openThumbBytes in interface IFormatReader

Overrides:

openThumbBytes in class MinimalTiffReader

Throws:

FormatException

java.io.IOException

close

public void close(boolean fileOnly)
           throws java.io.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 MinimalTiffReader

Throws:

java.io.IOException

getOptimalTileWidth

public int getOptimalTileWidth()

Description copied from interface: IFormatReader

Returns the optimal sub-image width for use with openBytes.

Specified by:

getOptimalTileWidth in interface IFormatReader

Overrides:

getOptimalTileWidth in class MinimalTiffReader

getOptimalTileHeight

public int getOptimalTileHeight()

Description copied from interface: IFormatReader

Returns the optimal sub-image height for use with openBytes.

Specified by:

getOptimalTileHeight in interface IFormatReader

Overrides:

getOptimalTileHeight in class MinimalTiffReader

initStandardMetadata

protected void initStandardMetadata()
                             throws FormatException,
                                    java.io.IOException

Description copied from class: BaseTiffReader

Parses standard metadata. NOTE: Absolutely no calls to the metadata store should be made in this method or methods that override this method. Data will be overwritten if you do so.

Overrides:

initStandardMetadata in class BaseTiffReader

Throws:

FormatException

java.io.IOException

initMetadataStore

protected void initMetadataStore()
                          throws FormatException

Description copied from class: BaseTiffReader

Populates the metadata store using the data parsed in BaseTiffReader.initStandardMetadata() along with some further parsing done in the method itself. All calls to the active MetadataStore should be made in this method and only in this method. This is especially important for sub-classes that override the getters for pixel set array size, etc.

Overrides:

initMetadataStore in class BaseTiffReader

Throws:

FormatException

handleFilter

private void handleFilter(org.w3c.dom.Element filter,
                          int channel)

processParentNode

private void processParentNode(org.w3c.dom.Node parent,
                               java.lang.String prefix)

getScanProfileXML

public java.lang.String getScanProfileXML()

Returns an XML string corresponding to the ScanProfile node. The QPTIFF specification indicates that the ScanProfile is XML, but in practice it may be XML or JSON.

getImageName

private java.lang.String getImageName(int coreIndex)

getIFDComment

private java.lang.String getIFDComment(int ifdIndex)

getImageType

private java.lang.String getImageType(int ifdIndex)

getIFDIndex

private int getIFDIndex(int coreIndex,
                        int no)

Returns the index of the IFD to be used for the given core index and image number. The IFD order in general is: - IFD #0 to n-1: full resolution images (1 RGB for BF data, n grayscale for FL) - IFD #n: RGB thumbnail - IFD #n+1 to (n*2)-1: 50% resolution images (optional) - IFD #n*2 to (n*3)-1: 25% resolution images (optional) ... - macro/overview image (optional) - label image (optional)
