    In This Topic

    This function loads and stitches together a tiled image, returning a HIGEAR handle to the image in memory.

    Declaration:

     
    Copy Code
    AT_ERRCOUNT ACCUAPI IG_load_tiles_stitch_W(
       const LPAT_WCHAR lpwszFileName,
       UINT nPage,
       LPAT_STITCH lpStitch,
       LPHIGEAR lphIGear
    );
    

    Arguments:

    Name Type Description
    lpwszFileName const LPAT_WCHAR Set to the Unicode filename of the image to load and stitch.
    nPage UINT Page number to load and stitch if this is a multi-page file. Note that page numbers begin at 1, not 0. Set nPage to 1 if this is not a multi-page file.
    lpStitch LPAT_STITCH Set to a structure of type AT_STITCH, which defines the reference tile number, and the number of row and columns of tiles.
    lphIGear LPHIGEAR ImageGear returns a HIGEAR handle to the newly stitched image in memory.

    Return Value:

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

    Supported Raster Image Formats:

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

    Sample:

    None

    Remarks:

    The AT_STITCH structure allows you to supply ImageGear with information on which tiles to use as the upper-left corner in the new stitched image, and how many tile rows and columns should be stitched together. For a graphical representation of how this works, see Working with Tiled Images.

    The nPage argument is set to 1 or greater if you are loading from a multi-page file, to indicate which page (image) you want to load. Set nPage to 1 for a non-multi-page file.

    If you set nPage to < 1, ImageGear will default the value to 1; if you set nPage to greater than the number of pages in the document, ImageGear will default the value to the last page number.
