    This function deletes the nCount number of elements starting with the nStartPage index from the page array of the multi-page image.

    Declaration:

     
    Copy Code
    AT_ERRCOUNT ACCUAPI IG_mpi_page_delete( 
            [IN] HMIGEAR hMIGear, 
            [IN] UINT nStartPage, 
            [IN] UINT nCount
    );
    

    Arguments:

    Name Type Description
    hMIGear HMIGEAR The handle to the allocated multi-page image.
    nStartPage UINT The first page to delete.
    nCount UINT The total number of pages to delete.

    Return Value:

    Returns the number of ImageGear errors that occurred during this function call. If there are no errors, the return value is IGE_SUCCESS.

    Supported Raster Image Formats:

    All pixel formats supported by ImageGear for C and C++.

    Sample:

    MFC Multipage

    Example:

     
    Copy Code
    HMIGEAR hMIGear;     /* handle to multi-page image */
    AT_ERRCOUNT nErrCount = IGE_SUCCESS; /* will hold returned error count */
    UINT nPageCount = 0; /* number of pages that should get from multi-page image */
    UINT i;
    HIGEAR hIGear;         /* handle of an image */
     ...
    /* initialize of multi-page image and assign it with external file */
    nErrCount = IG_mpi_page_count_get( hMIGear, &nPageCount );
    /* delete all pages and shrink array to entries pages */
    nErrCount = IG_mpi_page_delete( hMIGear, 0, nPageCount );
    

    Remarks:

    If the deleted pages are valid images, they are deleted with the function IG_image_delete(). Pages with higher indexes are shifted by removing the number and number of pages is decreased so that all pages are numbered from 0 to nPageCount-1.

    For multi-page vector documents, this function DELETES a page in the underneath vector document data. The following formats are currently supported by this API: PDF, PostScript.
