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 multi-page image and assign it with external file */ nErrCount = IG_mpf_page_count_get( hMIGear, &nPageCount ); if ( !nErrCount && (nPageCount > 0) ) IG_mpf_page_save( hMIGear, 0, 1, IG_COMPRESSION_NONE, IG_MPF_SAVE_INSERT ); |
|
Remarks:
If nSaveMode is IG_MPF_SAVE_INSERT, then the specified nCount number of pages are inserted, starting with nStartPage index, and all previous pages are shifted to a higher page number. If nSaveMode is IG_MPF_SAVE_REPLACE, then the function replaces the specified nCount number of pages, starting with the nStartPage index. If a page is NULL in the multi-page image, it is skipped and not saved.
This function takes each specified Nth page from a multi-page image and saves it as the Nth page into an external file. If the image is not associated with an external file, then it returns an error.

Not all format filters support IG_MPF_SAVE_REPLACE mode. Use the IG_fltr_info_get() function to obtain information about the supported features for specific format filters. |
