Public functions

applyEdit

Added in 1.0.0-alpha19

suspend fun applyEdit(record: FormEditInfo): Unit

Applies the changes specified by record to the form.

Any areas which are invalidated due to this operation are notified via OnPdfContentInvalidatedListener callback.

It is recommended to maintain a list of androidx.pdf.models.FormEditInfo applied to the document so they can be saved and restored across destructive events like low memory kills or configuration changes.

Parameters
`record: FormEditInfo`	The `androidx.pdf.models.FormEditInfo` to apply to the form.

Throws
`IllegalArgumentException`	if the provided `record` cannot be applied to the widget indicated by the index, or if the index does not correspond to a widget on the page.

applyEdits

suspend fun applyEdits(editsDraft: EditsDraft): List<String>

Applies a list of edits to the document sequentially. The edits are sorted by page number before applying using EditsDraft.getOperationsSortedByPage.

Parameters
`editsDraft: EditsDraft`	: edits to be applied on pdf document.

Returns
`List<String>`	List of annotationId for each operation in sequence of the order they were enqueued.

Throws
`PdfEditApplyException`	if any of the edit failed to be applied.

createWriteHandle

Added in 1.0.0-alpha19

fun createWriteHandle(): PdfWriteHandle

Creates a PdfWriteHandle which can be used to save the document to a ParcelFileDescriptor.
