nPage2 UINT Number of page 2 to swap with page 1.

Return Value:

Returns 0 if successful. Otherwise, returns the number of ImageGear errors that occurred during this function call.

None

Example:

 
Copy Code
AT_ERRCOUNT     nErrcount;            // Count of returned errors on stack
nErrcount = IG_fltr_pageswap_file("picture_multipage.tif", IG_FORMAT_TIF, 1, 2);

Remarks:

Use IG_fltr_info_get function to determine whether the format filter supports page swapping. If the flags returned by this function contain IG_FLTR_PAGESWAPSUPPORT, then the format filter supports the swapping procedure.
