public class FakeReader
extends FormatReader

FakeReader is the file format reader for faking input data. It is mainly useful for testing.

Examples:

• showinf 'multi-series&series=11&sizeZ=3&sizeC=5&sizeT=7&sizeY=50.fake' -series 9
• showinf '8bit-signed&pixelType=int8&sizeZ=3&sizeC=5&sizeT=7&sizeY=50.fake'
• showinf '8bit-unsigned&pixelType=uint8&sizeZ=3&sizeC=5&sizeT=7&sizeY=50.fake'
• showinf '16bit-signed&pixelType=int16&sizeZ=3&sizeC=5&sizeT=7&sizeY=50.fake'
• showinf '16bit-unsigned&pixelType=uint16&sizeZ=3&sizeC=5&sizeT=7&sizeY=50.fake'
• showinf '32bit-signed&pixelType=int32&sizeZ=3&sizeC=5&sizeT=7&sizeY=50.fake'
• showinf '32bit-unsigned&pixelType=uint32&sizeZ=3&sizeC=5&sizeT=7&sizeY=50.fake'
• showinf '32bit-floating&pixelType=float&sizeZ=3&sizeC=5&sizeT=7&sizeY=50.fake'
• showinf '64bit-floating&pixelType=double&sizeZ=3&sizeC=5&sizeT=7&sizeY=50.fake'
• showinf 'SPW&plates=2&plateRows=3&plateCols=3&fields=8&plateAcqs=5.fake'

Method Detail

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

                                     IOException

Description copied from interface: IFormatReader

Gets the 16-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.INT16 or FormatTools.UINT16, this method will return null.

Specified by:

get16BitLookupTable in interface IFormatReader

Overrides:

get16BitLookupTable 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.

isSingleFile

public boolean isSingleFile(String id)
                     throws FormatException,
                            IOException

Description copied from interface: IFormatReader

Returns true if this is a single-file format.

Specified by:

isSingleFile in interface IFormatReader

Overrides:

isSingleFile in class FormatReader

Throws:

FormatException

IOException

isThisType

public boolean isThisType(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 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.

Specified by:

getSeriesUsedFiles in interface IFormatReader

Overrides:

getSeriesUsedFiles in class FormatReader

findLogFiles

private void findLogFiles()

close

public void close(boolean fileOnly)
           throws IOException

Specified by:

close in interface IFormatReader

Overrides:

close in class FormatReader
