+### isConvertToGrayScale() {#isConvertToGrayScale--}
+```
+public boolean isConvertToGrayScale()
+```
+
+
+PDF file is composed of Text, Image, Attachment, Annotations, Graphs and other objects. You may come across a requirement to convert a PDF from RGB colorspace to grayscale so that it would be faster while printing those PDF files. Also when the file is converted to grayscale, the size of the document is also reduced but with this change, the quality of the document may drop. Currently, this feature is supported by the Pre-Flight feature of Adobe Acrobat.
+
+***Note:** The default value is  false .*
+
+**Returns:**
+boolean -  true  if the PDF is converted to grayscale,  false  otherwise.

+
+### isSubsetFonts() {#isSubsetFonts--}
+```
+public boolean isSubsetFonts()
+```
+
+
+Every font used to display text on the page contains set of glyphs for font characters. PDF specification supports "font subset" i.e. font with only those glyphs which are used. This may cause issues when text should be updated (since probably required glyphs are absent in the font), but for the document which is not planned to change this allows to decrease size.
+
+***Note:** The default value is  false .*
+
+**Returns:**
+boolean -  true  if fonts are subsetted,  false  otherwise.

+public boolean isCompressImages()
+```
+
+
+If the source PDF file contains images, consider compressing the images and setting their quality. In order to enable image compression, set this option to true. All the images in a document will be re-compressed. The compression is defined by the ImageQuality property, which is the value of the quality in percent. 100% is unchanged quality. To decrease image quality, set the ImageQuality property less than 100.
+
+***Note:** The default value is  false .*
+
+**Returns:**
+boolean -  true  if images are compressed,  false  otherwise.

+
+**Parameters:**
+| Parameter | Type | Description |
+| --- | --- | --- |
+| removePrivateInfo | boolean |  true  to remove private information,  false  otherwise. |
+
+### isUnembedFonts() {#isUnembedFonts--}
+```
+public boolean isUnembedFonts()
+```
+
+
+If the document uses embedded fonts it means that all font data is placed in the document. The advantage is that the document is viewable regardless of whether the font is installed on the user\\u2019s machine or not. But embedding fonts makes the document larger. The unembed fonts method removes all embedded fonts. This decreases the document size but the document may become unreadable if the correct font is not installed.
+
+***Note:** The default value is  false .*
+
+**Returns:**
+boolean -  true  if embedded fonts are unembedded,  false  otherwise.
+### setUnembedFonts(boolean unembedFonts) {#setUnembedFonts-boolean-}
+```
+public void setUnembedFonts(boolean unembedFonts)

+
+***Note:** The default value is  false .*
+
+**Parameters:**
+| Parameter | Type | Description |
+| --- | --- | --- |
+| unembedFonts | boolean |  true  to unembed the embedded fonts,  false  otherwise. |
+
+### isLinkDuplicateStreams() {#isLinkDuplicateStreams--}
+```
+public boolean isLinkDuplicateStreams()
+```
+
+
+Sometimes a document contains several identical resource streams (for example images). This may happen for example when a document is concatenated with itself. The output document contains two independent copies of the same resource stream. We analyze all resource streams and compare them. If streams are duplicated they are merged, that is, only one copy is left, references are changed appropriately and copies of the object are removed. Sometimes this decreases the document size.
+
+***Note:** The default value is  false .*
+
+**Returns:**
+boolean -  true  if duplicate streams are linked,  false  otherwise.
+### setLinkDuplicateStreams(boolean linkDuplicateStreams) {#setLinkDuplicateStreams-boolean-}
+```
+public void setLinkDuplicateStreams(boolean linkDuplicateStreams)
+```
+
+
+Sets whether to link duplicate streams in the PDF.
+
+***Note:** The default value is  false .*
+
+**Parameters:**
+| Parameter | Type | Description |
+| --- | --- | --- |
+| linkDuplicateStreams | boolean |  true  to link duplicate streams,  false  otherwise. |
+
+### isAllowReusePageContent() {#isAllowReusePageContent--}
+```
+public boolean isAllowReusePageContent()
+```
+
+
+If this property is set to true, the page content will be reused when optimizing the document for identical pages.
+
+***Note:** The default value is  false .*
+
+**Returns:**
+boolean -  true  if page content is reused,  false  otherwise.
+### setAllowReusePageContent(boolean allowReusePageContent) {#setAllowReusePageContent-boolean-}
+```
+public void setAllowReusePageContent(boolean allowReusePageContent)
+```
+
+
+Sets whether to allow reusing page content in the PDF.
+
+***Note:** The default value is  false .*
+
+**Parameters:**
+| Parameter | Type | Description |
+| --- | --- | --- |
+| allowReusePageContent | boolean |  true  to allow reusing page content,  false  otherwise. |
+
+### isRemoveUnusedStreams() {#isRemoveUnusedStreams--}
+```
+public boolean isRemoveUnusedStreams()
+```
+
+
+Sometimes a document contains unused resource streams. These streams are not \\u201cunused objects\\u201d because they are referenced from a page\\u2019s resource dictionary. This may happen in cases where an image has been removed from the page but not from the page resources. Also, this situation often occurs when pages are extracted from the document and document pages have \\u201ccommon\\u201d resources, that is, the same Resources object. Page contents are analyzed in order to determine if a resource stream is used or not. Unused streams are removed. Sometimes this decreases the document size.
+
+***Note:** The default value is  false .*
+
+**Returns:**
+boolean -  true  if unused streams are removed,  false  otherwise.
+### setRemoveUnusedStreams(boolean removeUnusedStreams) {#setRemoveUnusedStreams-boolean-}
+```
+public void setRemoveUnusedStreams(boolean removeUnusedStreams)
+```
+
+
+Sets whether to remove unused streams from the PDF.
+
+**Parameters:**
+| Parameter | Type | Description |
+| --- | --- | --- |
+| removeUnusedStreams | boolean |  true  to remove unused streams,  false  otherwise. |
+
+### isRemoveUnusedObjects() {#isRemoveUnusedObjects--}
+```
+public boolean isRemoveUnusedObjects()
+```
+
+
+A PDF document sometimes contains the PDF objects that are not referenced from any other object in the document. This may happen, for example, when a page is removed from the document page tree but the page object itself isn\\u2019t removed. Removing these objects doesn\\u2019t make the document invalid but rather shrinks it.
+
+***Note:** The default value is  false .*
+
+**Returns:**
+boolean -  true  if unused objects are removed,  false  otherwise.
+### setRemoveUnusedObjects(boolean removeUnusedObjects) {#setRemoveUnusedObjects-boolean-}
+```
+public void setRemoveUnusedObjects(boolean removeUnusedObjects)
+```
+
+
+Sets whether to remove unused objects from the PDF.
+
+***Note:** The default value is  false .*
+
+**Parameters:**
+| Parameter | Type | Description |
+| --- | --- | --- |
+| removeUnusedObjects | boolean |  true  to remove unused objects,  false  otherwise. |
