Working with Multi-Page Documents

Along with a single-page image handle (HIGEAR), ImageGear provides support for multi-page images. The HMIGEAR handle represents an array of single-page images. You can use ImageGear to:

Create and delete an internal representation of a multi-page image (HMIGEAR handle)
Open and associate a multi-page image file with an external file
Access and manipulate pages within the multi-page image
Manipulate pages in the external image file, such as loading, saving, swapping, and deleting pages
Retrieve information about multi-page images and about associated external files

The list of functions are divided into two categories:

Those that work with external associated multi-page files. These functions appear as IG_mpf_... .
Those that deal with multi-page image arrays. These functions begin with IG_mpi_... .

For example, the function IG_mpf_page_swap() swaps pages in the external file.
