Static Public Attributes | |
static final int | e_ImageCompressHigh = 10003 |
Compression mode: high. | |
static final int | e_ImageCompressjpeg = 10005 |
Compression mode: jpeg. | |
static final int | e_ImageCompressjpeg2000 = 10006 |
Compression mode: jpeg2000. | |
static final int | e_ImageCompressRetain = 10007 |
Compression mode: retain, which means no compression. | |
static final int | e_StretchBicubic = 0x80 |
When this is set, that means to do bicubic interpolation for zooming. | |
static final int | e_StretchDownsample = 0x04 |
When this is set, that means not to do halftone for shrinking or rotating. | |
static final int | e_StretchInterpol = 0x20 |
When this is set, that means to do interpolation for zooming. | |
static final int | e_StretchNoSmooth = 0x100 |
When this is set, that means not to do any interpolation for stretching. | |
static final int | e_StretchOff = 0x00 |
When this is set, that means do without stretching. | |
This class represents downsampling/recompression settings for color and grayscale images. This class object can be set to class OptimizerSettings and then be used to optimize a PDF document.
com.foxit.sdk.addon.optimization.ImageSettings.ImageSettings | ( | ) |
Constructor.
This constructor is to construct a color/gray 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.
com.foxit.sdk.addon.optimization.ImageSettings.ImageSettings | ( | ImageSettings | other | ) |
Constructor, with another image setting object.
[in] | other | Another ImageSettings object. |
boolean com.foxit.sdk.addon.optimization.ImageSettings.isEmpty | ( | ) |
Check whether current object is empty or not.
When the current object is empty, that means current object is useless.
void com.foxit.sdk.addon.optimization.ImageSettings.setCompressionMode | ( | int | mode | ) | throws com.foxit.sdk.PDFException |
Set compression mode used for optimizing color/gray 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.ImageSettings.e_ImageCompressjpeg as the deault value of this option.
[in] | mode | Image compression mode. Please refer to values starting from com.foxit.sdk.addon.optimization.ImageSettings.e_ImageCompressHigh and this should be one of these values. |
void com.foxit.sdk.addon.optimization.ImageSettings.setImageDPI | ( | int | dpi | ) | throws com.foxit.sdk.PDFException |
Set the image DPI used for optimizing color/gray images in a PDF document.
For a newly constructed object, if this function is not called to set option, that means to use 150 as the deault value of this option.
[in] | dpi | DPI value. |
void com.foxit.sdk.addon.optimization.ImageSettings.setQuality | ( | int | quality | ) | throws com.foxit.sdk.PDFException |
Set the quality for lossy compression modes, used for optimizing color/gray images in a PDF document.
For a newly constructed object, if this function is not called to set this option, that means to use 2 as the deault value of this option.
[in] | quality | Quality value for lossy compression modes. Valid range: from 1 to 5. 5 means lossless (if possible). |
void com.foxit.sdk.addon.optimization.ImageSettings.setStretchMode | ( | int | mode | ) | throws com.foxit.sdk.PDFException |
Set stretch mode used for optimizing color/gray 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.ImageSettings.e_StretchBicubic as the deault value of this option.
[in] | mode | Stretch mode. Please refer to values starting from com.foxit.sdk.addon.optimization.ImageSettings.e_StretchOff and this should be one of these values. |
