t - offset across the T-axis of the pixel buffer.

x - Top left corner of the tile, X offset.

y - Top left corner of the tile, Y offset.

w - Width of the tile.

h - Height of the tile.

Throws:

java.io.IOException - if there is a problem writing to the pixel buffer.

java.nio.BufferOverflowException - if an attempt is made to write off the end of the file.

getResolutionLevel

public int getResolutionLevel()

Description copied from interface: PixelBuffer

Retrieves the active resolution level.

Specified by:

getResolutionLevel in interface PixelBuffer

Returns:

The active resolution level. The level will be non-negative and less than PixelBuffer.getResolutionLevels(). Resolution level 0 is the smallest resolution and resolution level getResolutionLevels() - 1 is the largest resolution. This is the inverse of how Bio-Formats indexes resolutions.

getResolutionLevels

public int getResolutionLevels()

Description copied from interface: PixelBuffer

Retrieves the number of resolution levels that the backing pixels pyramid contains.

Specified by:

getResolutionLevels in interface PixelBuffer

Returns:

The number of resolution levels. This value does not necessarily indicate either the presence or absence of a pixels pyramid.

getTileSize

public java.awt.Dimension getTileSize()

Description copied from interface: PixelBuffer

Retrieves the tile size for the pixel store.

Specified by:

getTileSize in interface PixelBuffer

Returns:

The dimension of the tile or null if the pixel buffer is not tiled.

getResolutionDescriptions

public java.util.List<java.util.List<java.lang.Integer>> getResolutionDescriptions()

Description copied from interface: PixelBuffer

Return a list of lists each of which has sizeX, sizeY for the resolution level matching the index of the outer index. For example, if an image has 2 resolution levels of size 2048x1024 and 1024x512 then this returns: [[2048,1024],[1024,512]]

Specified by:

getResolutionDescriptions in interface PixelBuffer

Returns:

a list of lists containing sizeX, sizeY for each resolution level

setResolutionLevel

public void setResolutionLevel(int resolutionLevel)

Description copied from interface: PixelBuffer

Sets the active resolution level.

Specified by:

setResolutionLevel in interface PixelBuffer

Parameters:

resolutionLevel - The resolution level to be used by the pixel buffer. The level should be non-negative and less than PixelBuffer.getResolutionLevels(). Resolution level 0 is the smallest resolution and resolution level getResolutionLevels() - 1 is the largest resolution. This is the inverse of how Bio-Formats indexes resolutions.
