applyEdit
fun applyEdit(editRecord: FormEditRecord): MutableList<Rect!>
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 FormEditRecord
s, performs a click on android.graphics.pdf.models.FormEditRecord#getClickPoint()
For set text type FormEditRecord
s, sets the text value of the form widget.
For set indices type FormEditRecord
s, sets the android.graphics.pdf.models.FormEditRecord#getSelectedIndices()
as selected and all others as unselected for the form widget indicated by the record.

render
fun render(
destination: Bitmap,
destClip: Rect?,
transform: Matrix?,
params: RenderParams
): Unit
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 android.annotation.WorkerThread
as it is long-running task.
Parameters | |
---|---|
destination |
Bitmap: Destination bitmap to write to. This value cannot be null . |
destClip |
Rect?: If null, default zoom is applied. In case the value is non-null, the value specifies the top top-left corner of the tile. |
transform |
Matrix?: Applied to scale the bitmap up/down from default 1/72 points. This value may be null . |
params |
RenderParams: Render params for the changing display mode and/or annotations. This value cannot be null . |
Exceptions | |
---|---|
java.lang.IllegalStateException |
If the document/page is closed before invocation. |
searchText
fun searchText(query: String): MutableList<PageMatchBounds!>
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 android.annotation.WorkerThread
as it is long-running task.
Parameters | |
---|---|
query |
String: plain search string for querying the document This value cannot be null . |
Return | |
---|---|
MutableList<PageMatchBounds!> |
List of PageMatchBounds representing the bounds of each match on the page. This value cannot be null . |
Exceptions | |
---|---|
java.lang.IllegalStateException |
If the document/page is closed before invocation. |
selectContent
fun selectContent(
start: SelectionBoundary,
stop: SelectionBoundary
): PageSelection?
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 android.annotation.WorkerThread
as it is long-running task.
Parameters | |
---|---|
start |
SelectionBoundary: boundary where the selection starts (inclusive) This value cannot be null . |
stop |
SelectionBoundary: boundary where the selection stops (exclusive) This value cannot be null . |
Return | |
---|---|
PageSelection? |
collection of the selected content for text, images, etc. |

---|---|
java.lang.IllegalStateException |
