applyEdit

public List<Rect> applyEdit (FormEditRecord editRecord)

Applies a FormEditRecord to the PDF.

Apps must call render(android.graphics.Bitmap, android.graphics.Rect, android.graphics.Matrix, android.graphics.pdf.RenderParams) to render new bitmaps for the corresponding areas of the page.

For click type FormEditRecords, performs a click on FormEditRecord.getClickPoint()

For set text type FormEditRecords, sets the text value of the form widget.

For set indices type FormEditRecords, sets the FormEditRecord.getSelectedIndices() as selected and all others as unselected for the form widget indicated by the record.

close

public void close ()

Closes this page.

getFormWidgetInfoAtIndex

public FormWidgetInfo getFormWidgetInfoAtIndex (int annotationIndex)

Returns information about the widget with annotationIndex.

getFormWidgetInfoAtPosition

public FormWidgetInfo getFormWidgetInfoAtPosition (int x, 
                int y)

Returns information about the widget at the given point.

getFormWidgetInfos

public List<FormWidgetInfo> getFormWidgetInfos ()

Returns information about all form widgets on the page, or an empty list if there are no form widgets on the page.

getFormWidgetInfos

public List<FormWidgetInfo> getFormWidgetInfos (int[] types)

Returns information about all form widgets of the specified types on the page, or an empty list if there are no form widgets of the specified types on the page.

getGotoLinks

public List<PdfPageGotoLinkContent> getGotoLinks ()

Gets bookmarks and goto links present on the page of a pdf document. Goto Links are the internal navigation links which directs the user to different location within the same document.

getHeight

public int getHeight ()

Returns the height of the given Page object in points (1/72"). It is not guaranteed that all pages will have the same height and the viewport should be resized to the given page height.

getImageContents

public List<PdfPageImageContent> getImageContents ()

Return list of PdfPageImageContent found on the page, ordered left to right and top to bottom. It contains all the content associated with images found on the page including alt text. The list will be empty if there are no results found. Currently, localisation does not have any impact on the order in which PdfPageImageContent is returned.

getIndex

public int getIndex ()

Gets the page index.

getLinkContents

public List<PdfPageLinkContent> getLinkContents ()

Get the bounds and URLs of all the links on the given page.

getTextContents

public List<PdfPageTextContent> getTextContents ()

Return list of PdfPageTextContent found on the page, ordered left to right and top to bottom. It contains all the content associated with text found on the page. The list will be empty if there are no results found. Currently, localisation does not have any impact on the order in which PdfPageTextContent is returned.

getWidth

public int getWidth ()

Returns the width of the given Page object in points (1/72"). It is not guaranteed that all pages will have the same width and the viewport should be resized to the given page width.

render

public void render (Bitmap destination, 
                Rect destClip, 
                Matrix transform, 
                RenderParams params)

Renders a page to a bitmap. In case of default zoom, the Bitmap dimensions will be equal to the page dimensions. In this case, Rect parameter can be null.

In case of zoom, the Rect parameter needs to be specified which represents the offset from top and left for tile generation purposes. In this case, the Bitmap dimensions should be equal to the tile dimensions.

Note: The method will take care of closing the bitmap. Should be invoked on the ERROR(/android.annotation.WorkerThread) as it is long-running task.

searchText

public List<PageMatchBounds> searchText (String query)

Search for the given string on the page and returns the bounds of all the matches. The list will be empty if there are no matches on the given page. If this function was invoked previously for any page, it will wait for that operation to complete before this operation is started.

Note: Should be invoked on the ERROR(/android.annotation.WorkerThread) as it is long-running task.

selectContent

public PageSelection selectContent (SelectionBoundary start, 
                SelectionBoundary stop)

Return a PageSelection which represents the selected content that spans between the two boundaries. The boundaries can be either exactly defined with text indexes, or approximately defined with points on the page. The resulting selection will also be exactly defined with both indexes and points. If the start and stop boundary are both at the same point, selects the word at that point. In case the selection from the given boundaries result in an empty space, then the method returns null. The start and stop SelectionBoundary in PageSelection resolves to the "nearest" index when returned.

Note: Should be invoked on a ERROR(/android.annotation.WorkerThread) as it is long-running task.

finalize

protected void finalize ()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the finalize method to dispose of system resources or to perform other cleanup.

The general contract of finalize is that it is invoked if and when the Java virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. The finalize method may take any action, including making this object available again to other threads; the usual purpose of finalize, however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded.

The finalize method of class Object performs no special action; it simply returns normally. Subclasses of Object may override this definition.

The Java programming language does not guarantee which thread will invoke the finalize method for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates.

After the finalize method has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded.

The finalize method is never invoked more than once by a Java virtual machine for any given object.

Any exception thrown by the finalize method causes the finalization of this object to be halted, but is otherwise ignored.
