Detailed Description

Program to split an image into overlapping tiles.

Function Documentation

◆ img_tile_with_overlap()

int img_tile_with_overlap	(	Bimage *	p,
		Bstring	outputfile,
		Vector3< int >	size,
		Vector3< int >	overlap,
		int	digits,
		int	first_number,
		DataType	nudatatype
	)

Writes overlapping tiles into new images.

Parameters

*p	image = tile.
outputfile	output file name.
size	tile size.
overlap	tile overlap.
digits	number of digits in tile file number.
first_number	first tile file number.
nudatatype	tile datatype.

Returns

int number of tiles.

Each tile is copied into a new image and written with a numbered file name.
The tiles at the ends of the block may not be the same size as the
other tiles, being truncated at the end of the input data.
A text file with the extension ".tiles" is written with the positions
of the tiles, and it is needed to patch the image together again.

◆ main()
