useOldPhysicalSizeCalculation

public boolean useOldPhysicalSizeCalculation()

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 FormatReader

isThisType

                   throws java.io.IOException

Description copied from interface: IFormatReader

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

Specified by:

isThisType in interface IFormatReader

Overrides:

Throws:

java.io.IOException

get8BitLookupTable

public byte[][] get8BitLookupTable()

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

get16BitLookupTable

public short[][] get16BitLookupTable()

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.

                        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

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.
