L_LTDOC2_API L_INT EXT_FUNCTION L_Doc2AddPage(hDoc, pBitmap, nPageIndex)
L_HDOC2 hDoc; |
handle to the OCR document |
pBITMAPHANDLE pBitmap; |
pointer to the bitmap handle |
L_INT nPageIndex; |
position at which to insert the page |
Adds a new page to the OCR document.
Parameter |
Description |
hDoc |
Handle to the OCR document. |
pBitmap |
Pointer to the bitmap handle, that references the new page being inserted into the internal OCR list of pages. |
nPageIndex |
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. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
This function converts the inserted page(s) to be matched with the OCR requirements.
In addition, this function checks the color order for each bitmap loaded. If a bitmap has the color order reversed (i.e. white to black) then the function will convert the color order to be normal (i.e. black to white).
