getCompressionTypes

public String[] getCompressionTypes()

Overrides:

getCompressionTypes in class ImageWriteParam

setCompressionType

public void setCompressionType(String compressionType)

Set the compression type. Must be 'lossless' (default) or 'lossy'.

Overrides:

setCompressionType in class ImageWriteParam

getCompressionType

public String getCompressionType()

Overrides:

getCompressionType in class ImageWriteParam

unsetCompression

public void unsetCompression()

Overrides:

shouldWriteSOPMarkers

public boolean shouldWriteSOPMarkers()

setWriteSOPMarkers

public void setWriteSOPMarkers(boolean writeSOPMarkers)

Write SOP markers after each packet.

Parameters:

writeSOPMarkers - flag if sop markers should be written

shouldWriteEPHMarkers

public boolean shouldWriteEPHMarkers()

setWriteEPHMarkers

public void setWriteEPHMarkers(boolean writeEPHMarkers)

Write EPH marker after each header packet.

Parameters:

writeEPHMarkers - flag if eph markers should be written

setCompressionQuality

public void setCompressionQuality(float quality)

Set the compression quality. Automatically switches compression type to lossy. ImageWriteParam.setCompressionType(java.lang.String) must have been set to ImageWriteParam.MODE_EXPLICIT. Quality must be between 0.0 (worst) and 1.0 (best).

Overrides:

setCompressionQuality in class ImageWriteParam

getNumResolutions

public int getNumResolutions()

setNumResolutions

public void setNumResolutions(int numResolutions)

Set the number of resolutions to encode in the output image. Each resolution will be 2^num times smaller than the native resolution.

Parameters:

numResolutions - the num resolutions

getProgressionOrder

public OpenJp2ImageWriteParam.ProgressionOrder getProgressionOrder()

setProgressionOrder

public void setProgressionOrder(OpenJp2ImageWriteParam.ProgressionOrder progOrder)

Set the progression order of the encoded image.

Parameters:

progOrder - the progression order
