create an MonoImageSettings object with default options

Method Detail

setImageDPI

public void setImageDPI(double maximum,
               double resampling)

Sets the maximum and resampling dpi for monochrome images. By default these are set to 450 and 300 respectively.

Parameters:

maximum - the highest dpi of an image before it will be resampled

resampling - the image dpi to resample to if an image is encountered over the maximum dpi

setCompressionMode

public void setCompressionMode(int mode)

setDownsampleMode

public void setDownsampleMode(int mode)

forceRecompression

public void forceRecompression(boolean force)

Sets whether recompression to the specified compression method should be forced when the image is not downsampled. By default the compression method for these images will not be changed.

Parameters:

force - if true the compression method for all images will be changed to the specified compression mode

forceChanges

public void forceChanges(boolean force)

Sets whether image changes that grow the PDF file should be kept. This is off by default.

Parameters:

force - if true all image changes will be kept.
