Adds a new page to the OCR document.
Syntax
Parameters
- image
- An RasterImage object that references the new page to be inserted into the internal OCR list of pages.
- pageIndex
-
Position in the list of pages at which to insert the new page.
Use -1 to append the page to the end of the list.Use zero-based indexing.
For example, if there are 10 pages in the list, the index of the last page is 9. If you insert a page within the list, the indices of other pages will change automatically to accommodate the insertion.
