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 Professional.
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.
