Constructor & Destructor Documentation

◆ MonoImageSettings() [1/2]

com.foxit.sdk.addon.optimization.MonoImageSettings.MonoImageSettings ( )

Constructor.

This constructor is to construct a monochrome image settings object with default setting options. User can also calling "set" methods in this class to change these setting options. Please refer to comment of these "set" methods for more details about default values.

◆ MonoImageSettings() [2/2]

com.foxit.sdk.addon.optimization.MonoImageSettings.MonoImageSettings ( MonoImageSettings  other)

Constructor, with another result information object.

Parameters
[in]otherAnother monochrome image settings object.

Member Function Documentation

◆ isEmpty()

boolean com.foxit.sdk.addon.optimization.MonoImageSettings.isEmpty ( )

Check whether current object is empty or not.

When the current object is empty, that means current object is useless.

Returns
true means current object is empty, while false means not.

◆ setCompressionMode()

void com.foxit.sdk.addon.optimization.MonoImageSettings.setCompressionMode ( int  mode) throws com.foxit.sdk.PDFException

Set compression mode used for optimizing monochrome images in a PDF document.

For a newly constructed object, if this function is not called to set option, that means to use com.foxit.sdk.addon.optimization.MonoImageSettings.e_ImageCompressCCITT4 as the deault value of this option.

Parameters
[in]modeImage compression mode. Please refer to values starting from com.foxit.sdk.addon.optimization.MonoImageSettings.e_ImageCompressHigh and this should be one of these values.
Returns
None.

◆ setImageDPI()

void com.foxit.sdk.addon.optimization.MonoImageSettings.setImageDPI ( int  dpi) throws com.foxit.sdk.PDFException

Set the image DPI used for optimizing monochrome images in a PDF document.

For a newly constructed object, if this function is not called to set option, that means to use 250 as the deault value of this option.

Parameters
[in]dpiDPI value.
Returns
None.

◆ setStretchMode()

void com.foxit.sdk.addon.optimization.MonoImageSettings.setStretchMode ( int  mode) throws com.foxit.sdk.PDFException

Set stretch mode used for optimizing monochrome images in a PDF document.

For a newly constructed object, if this function is not called to set this option, that means to use com.foxit.sdk.addon.optimization.MonoImageSettings.e_StretchBicubic as the deault value of this option.

Parameters
[in]modeStretch mode. Please refer to values starting from com.foxit.sdk.addon.optimization.ImageSettings.e_StretchOff and this should be one of these values.
Returns
None.
